Computer Networking Business: Start-up and Hiring Key Employees

Hiring employees in the computer networking business is an exact science. Many computer networking business owners don't have the knowledge required to hire the best and most experienced employees, even though hiring these people is one of the most beneficial factors of business growth. There is a formula to follow that can help you, as a business owner hire the right employees for your computer networking business.

Hiring is a very systematic process, and each computer networking business has to be ready for a very long process. Once you make a list of the most useful candidates for the jobs, the interview process begins. Be prepared to conduct second and even third interviews to ensure you get the right people to help you in your computer networking business.

Classified Ads That Emphasize Opportunity

Job postings for your computer networking business should advertise an opportunity, not simply a job or a position. The words you use to describe the opportunity should reflect the full scope of your company and attract those looking for a career, not just a shorter-term job.

The Job Description

The employees you want will expect a clear description of the job and its responsibilities. In your description, include definitions, expectations, salary, bonuses and all perks.

Honest And Open Reference Conversations

Establish an open and friendly relationship right off the bat with candidate references in order to open up communication. Ask about the applicant's strengths and weaknesses after you've put the reference at ease, and keep in mind that most often a reference is only trying to protect himself when he is guarded with information.

Resumes And Applications

You should demand an applicant fill out completely both an application and a resume. A computer networking business will find out much more about a candidate by expecting both items. Applications provide the answers to important questions regarding felony arrest, citizenship, etc., and make work history easier to determine than a resume alone.

Listening Skills

The ability to listen is a critical skill in the computer networking business, and if a candidate cannot stay focused or truly process what you are saying in an interview, chances are he will not listen as a service-oriented employee.

Following specific guidelines when hiring all employees will guarantee your hires are consistently of the best quality and best fit for your particular computer networking business.

Computer network engineers are prepared for a variety of duties involved in designing new computers, testing computers, and maintaining existing computer network systems.

Computer Network Installation

Computer network installation has become an essential prerequisite for any efficient modern-day business as it allows employees to truly work as a team by sharing information, accessing the same database and staying in touch constantly. For a computer network to give the best results, a lot of detailed planning and foresight is required before installation.

Firstly, an organisation needs to clearly define its requirements – how many people would use the network, how many would use it locally (within the office) and how many might require remote access (from a different location), how many computers and other devices (servers, printers, scanners) would be connected to the network, what are the needs of the various departments and who would be in charge of running/managing the network. It also helps if one can anticipate the direction the company would take in the near future so potential growth can be factored in during computer network installation.

The technology issues should also be ironed out in advance – hardware, software, servers, switches, back-up devices, cables and network operating systems. Make sure you have the required licenses to run the software on all your machines before installing a computer network. Alongside computer network installation should proceed the building of a dedicated technical support staff, either within your own organisation or outside consultants. Delegate responsibility clearly for network management. Before installing the network, you also need to choose the security mechanism to protect corporate data and keep viruses at bay.

The transition to a new or upgraded computer network can bring some teething problems. To minimise chances of confusion, the company might need to train its staff to make them familiar with the new system. Careful planning will to a large extent prevent crises like system downtime and network crashes.

Wireless Computer Network Rentals: The New Technology Trend

Consider the convenience and added benefits of renting today's wireless technology.

Wireless networks have a big advantage over wired networks, especially for short term projects where the internet and rental computers, printers and projectors are deployed.

Wireless networks are easier and faster to setup than wired networks. Wireless devices add flexibility and save time. With wireless you can move your laptops, projectors and printers around and still maintain connectivity. Best of all, you don't have to run cat5 wires to routers, computers, printers and switches.

Here are some of the wireless products that are commonly rented for company projects:

Wireless Router Rentals

A wireless router is a networking device that connects computers to the internet. With a router you can share an internet connection between multiple computers on the network. Note: The internet cable needs to be connected directly into the wireless router.

Rent Wireless Access Point (WAP)

A wireless access point is a networking device that allows wireless-equipped computers and other devices to communicate with a wired network. A WAP may also be used to expand the range of an existing wireless network.

Rent Wireless Adapters

A wireless adapter is a device that adds wireless network functionality to a computer or laptop. There are three types of wireless adapters. PCI Adapters are for desktop computers. As the name suggests, they can be installed in an available PCI slot. PCMCIA Adapters, also known as PC Cards, are for notebooks. Installation is as simple as pushing the card into an available PCMCIA slot. Lastly, there are USB Adapters. These adapters are compatible with desktop and notebook computers.

Rent Wireless Print Servers

A wireless print server connects a printer to the wireless network, allowing any computer on the network to wirelessly access the printer at any time.

Rent Wireless Projectors

A wireless projector allows a computer user to wirelessly connect and display the computer video on a screen. All you need is a wireless adapter in your computer or notebook and the software that comes with the projector. Today's advanced wireless projectors allow one computer to connect to multiple projectors AND multiple computers to connect to a single projector.

If you want to have a really impressive presentation, consider renting two or more wireless projectors. Bring your multimedia presentation to the next level by putting on multiple unique screens of your data and video presentation. For example: have animation on one screen and data on another!

Another benefit of wireless projectors is having the ability to have multiple presenters displaying their presentations right from their own wireless laptop or computer. Consider a corporate meeting with presentations from finance, operations, sales and marketing managers.

Local Area Networks - Computer Networking

Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.

LANs systems can be defined and connected in many different ways. This is the reason for the standardization for every one can have a common ground to start from. “The LANs described Herein are distinguished from other types of data networks in that they are optimized for a moderate size geographic area such as a single office building, warehouse, or a campus. The IEEE 802 LAN is a shared medium peer-to-peer communications network that broadcasts information for all stations to receive. As a consequence, it does not inherently provide privacy. The LAN enables stations to communicate directly using a common physical medium on a point-to-point basis without any intermediate switching node being required. There is always need for an access sublayer in order to arbitrate to access to the shared medium. The network is generally owned, used, and operated by a single organization. This is in contrast to Wide Area Networks (WANs) that interconnect communication facilities in different parts of a country or are used as a public utility. These LANs are also different from networks, such as backplane buses, that are optimized for the interconnection of devices on a desk top or components within a single piece of equipment.”(IEEE 802 Standard 1990) That is the standard definition for LANs by Institute of Electrical and Electronics Engineer committee 802. They are the committee used to set the standard in workmanship and operations for technicians that set-up and perform maintenance on LANs systems. And through all the technical words what they are trying to say is a LAN is a small area network that distributes information among computer in a small work environment unlike WANs that distribute information across global areas. “It is usually the case that LAN is owned by the same organization that owns the attached devices. For WANs, this is less often the case, or at least a significant fraction of the network assets are not owned. This has two implications. First, care must be taken in the choice of LAN, since there may be substantial capital investment (compared to dial-up or leased charges for wide-area networks) for both purchase and maintenance. Second, the network management responsibility for a local network falls solely on the user”. (Local and metropolitan area networks 1997).

The question now is you have a standard and you have a connection now how do you manage the system to run flawlessly?” Networks use protocols, or rules, to exchange information though a single shared connection. These protocols prevent collisions of data caused by simultaneous transmission between two or more computers. Computers on most LANs use protocols known as Ethernet or Token Ring. An Ethernet-linked computer checks if a shared connection is used. If not, the computer transmits data. Since computer can sense an idle connection and send data at the same time, transmitting computers continue to monitor their shared connection and stop transmitting if a collision occurs. Token Ring protocols pass a special message called a token through the network. A computer that receives the token is given permission to send a packet of information or, if the computer has no packet to send, it passed the token to the next computer.”(Local Area Network Microsoft 2000) I know that it is complicated to understand, but for the actual user the software takes care of most all of the management for you.

There are seven things that a LANs can do that you cannot with ease do with non-networked stand-alone systems. First sharing files “ A LAN enables many user to share a single copy of a file stored on a central file server computer.”(Introduction to Networking 1992) Transferring files “A LAN enables you to copy files from machine to machine without having to exchange floppy disks.”(Understanding Data Communications 1993) Access information and files “A LAN enables anyone to run the accounting software, for example, or other application software from any of the workstations”(Introduction to Networking 1992) Share applications “A LAN enables two people to use the same copy of the Microsoft Word word processing program simultaneously”(Introduction to Networking 1992) Simultaneously key data into an application. Printer sharing and electronic mail with in the system.

In conclusion the LAN has become essential in the modern work environment. The ever-growing need for advancement has become a very profitable industry in its self and it will continue to grow for a long time to come. For now we are barely skimming the possibilities and uses for this new networking technology.

Cabling Your Home for Computer Network - Still a Requirement?

With proliferation of wireless networking and communication equipment it is oh-so-tempting to cut the cord and save a significant sum of money in the process. But is everything that a regular computer networking user needs can be done using just wireless network? Let’s take a look at some pros and contras:

1. One important advantage of having a cabled network is the available bandwidth or simply speed. At the present point in time the speed of connection via a simple and inexpensive CAT5E cable can be 1000Mbit/sec, whereas the best that IEEE802.11g (one of the many flavors of Wi-Fi) can offer is only 54Mbit/sec. It may not seem so significant if you think you are only browsing Internet, and the DSL speed available to you is 1.5Mbit/sec. However, if you need to print via your network connection on a remote printer, you should realize that the print jobs, depending on the amount of graphic data in them, can easily reach dozens and even hundreds megabytes. Since 1Byte=8bit one 100MByte print job will take 15 seconds (and in reality this time can be much longer) to transmit via a Wi-Fi wireless connection, and this time shrinks to mere 1 sec or less on wired 1000MBit/s Ethernet connection. Same principal applies to transferring files, backing up files on other computers in the network etc.

2. It is not possible today and with all probability will not be possible in the future to transmit power needed for your networking device via the wireless link. Unless, of course, you would be willing to be subjected to very high levels of microwave radiation. Thus a device that was marketed to you as “un-tethered” will in fact be very much tethered via the power cord or will have to be re-charged every so often. The power requirements are increasingly important for devices that are expected to be always online, such as phone sets. Therefore it is best to have it connected via a cable that can deliver both power and the communication signal at the same time.

3. Wireless communications are very much proprietary and require whole gamut of conversion equipment to transmit multi-media signals. The same CAT5E cable can without any modification support phone, computer network, balanced line level audio signal, baseband video signal as well as host of other, more specialized, control applications’ signals. With inexpensive adapters called “baluns” the same cable can carry significant number of channels of broadband television or carry a baseband video, such as security camera output, through great distances. All of those applications, except the computer network of course, will require specialized expensive conversion equipment if they needed to be transmitted via a Wi-Fi link.

4. The cost benefit of not running wires around the house is not as simple as issue as it seems. Having installed a wireless network at home you have only eliminated the need to wire for a single application – computer network. A modern home, however, requires all kinds of wiring to run even without regard to computers. The power and phones are obvious examples, as well as thermostats and security systems. Pre-wired speakers are common and most homes today have intercom systems as a desirable option, and those also require extensive wiring. It is very likely that the same contractor running the intercom or security cables is qualified to run computer cables – CAT5E or better. If you are building a home, you should definitely check if computer cabling option is available in your new home, and our advice is to go ahead and purchase it before the walls close. It is going to be a pretty involved and expensive procedure to install the cables later. As an added cost benefit of a wired computer network you will find that all modern computers ship with wired Ethernet network interface card included, and the latest models ship with 1000MBit/sec cards that are essentially free for the computer’s owner.

There are multiple sources of information available on proper planning and design of a residential cabling for voice, data, audio, video and other applications. One of the best sources is the TIA/EIA-570B standard, most resent release of which has been published in 2004. The standard outlines recommended types of the cables, principals of cable distribution in a single- and multi-dwelling units as well as recommended amount of cables to be installed based on the size of the house.

In conclusion, cutting the wire seems like a step forward, some sort of liberation of computer from the bonds of the infrastructure. I would caution the reader, however, to take a more balanced and informed approach before joining the “wireless revolution”. There are still (and will remain in foreseen future) sound reasons to include properly designed cabling system into the list of your dream home options.

An Overview Of Computer Networks

My second degree, or should I say my second go through inside the education system was in networking. I'm a certified Novell and Microsoft engineer, not that I'm all that excited about the fact. Networking is actually pretty mindless work once you learn it. It's pretty much do it by the numbers based on what the customer wants. After you hook everything up the software installation is pretty straight forward. My 16 year old daughter could do it or as GEICO would say, a caveman could do it.

In this article I'm just going to cover the basics of what a network is and the types of networks. I'll go into more detail in later articles.

A network is simply a means for computers to speak to each other, or communicate with each other. With a network, computers can receive emails from each other, send files to each other, instant message each other and a variety of other things. This is something that we take for granted today but there was a time when networks were not so sophisticated and not all that efficient either.

There are basically two types of networks.

The simplest network is a LAN or Local Area Network. This is where all the computers in the network are located in one place such as an office building. Within this type of network you have 2 ways to connect.

The simplest way is peer to peer. This is where 2 or more computers are hooked up directly to each other. In other words if you have 5 computers you would have computer 1 hooked into computer 2 which would be hooked into computer 3 and so on. In this type of connection each computer is dependent on the other. So if computer 3 would go down then computers 1 and 2 would not be able to communicate or exchange information with computers 4 and 5 and visa versa. That is the main problem with a peer to peer network. Also in peer to peer networks the write process between computers leads to data corruption problems. This is not something they teach you in school but something you learn from experience.

The more common type of LAN connection is client server. This is where all the computers in the network are connected to each other via a central computer. This kind of connection does require more work in set up but is more efficient, carries data better and if one computer goes down the others aren't affected. However, should the server go down then all the computers on the network would be affected as far as their ability to get information from the other computers and the server itself. They, however, would still be able to do work locally on their own such as with a word processing program, unless the word processing program was located on the server. Then it would not be available. Usually, however, most applications are installed on each computer. What is most commonly lost when a server goes down is the ability to retrieve data that is common to everyone in the network, say an in house database of all employees.

The second type of network is a WAN or wide area network. This is where several LAN networks or even single computers are connected to a much larger network. A perfect example of a WAN is the Internet. This is where users from all over the world can interact with each other through email, chat rooms and instant messaging. WANs are enormous to say the least and are very intricate in their design, requiring hubs from all over the world to stay connected. One hub goes down and it can affect connections for millions of people though there are protocols instituted to reroute connections if a hub does go down.

Get the Highest Speed Out of Your Wireless Computer Network

When it comes to a wireless standard, the first thing we all look at is how fast will this baby run! And you know the trade-offs, you can spend a lot of money to get the fastest thing running, or you can back off a little and save a lot.

The good thing about wireless networks is that the price difference between wireless standards is almost gone. There are some things that could add up, but I will explain the difference and why you might want to go that route or not.

Now, let's get to the different wireless standards you can choose from.

1. 802.11b - 11Mbit at 2.GHz
2. 802.11a - 54Mbit as 5.0GHz
3. 802.11g - 54Mbit at 2.4GHz
4. Hybrid Systems

When you get ready to purchase your equipment, you will see a lot of systems saying that they are faster than these standards listed above. Most will say 108Mbit per second, some 125Mbit per second and a few even higher. To operate at these speeds usually requires you to only use their network cards to access their access points, some of them require a specific card from them to get that speed. If any other card connects, then they will drop back to the standard speed and you lose the extra speed you probably paid extra to get.

What Should You Get

I was purchasing equipment for a completely new wireless setup. We only had one older wireless computer and I replaced the card in it with a new one. I did purchase a system that advertised the 108Mbit speeds since I knew who was going to connect to it.

If you are building a new network setup, I suggest you purchase a system that will run faster than the standard, but only if you know who is connecting. If not, then get a system that runs on the 802.11g standard. The price is about the same as 802.11b but runs 5 times faster.

Computer Network Management

Today it is almost inconceivable for a business not to have computers, whether it is a construction company or a high technology firm. When a business has more than one computer, they are almost always connected together in a local area network. These networks may be more or less advanced and therefore more or less costly.

Companies invest so much (in terms of both money and time) in a local area networks because there are many advantages that a local area network brings to a business and how it is administered.

Some businesses use a local area network in such a way they are highly dependent on it always working. If the company's network fails, then you may see all the employees chatting away in the corridors because they can't do their work. This means big losses for the company and causes stresses on the employees. All companies must consider their local area networks a vital asset and downtime must be avoided. This imposes huge demands on the network staff to keep such networks running almost 100% of the time.

The advantages of Computer Network Management

One of the main advantages of installing and maintaining LANs is the opportunity they create for better communication and cooperation between employees and customers.

Security considerations: Local Area Network security can be both a help and hindrance. Comprehensive security is beneficial because it provides a central and safe strategy for data access and disaster recovery. All information is protected by the design and implementation of the network security solution. On the other hand, interconnecting computers in local area networks creates a security risk, since doing so makes it technically possible for intruders to access many machines on the network at once.

Cost considerations: Installing a local area network is a relatively expensive project. Servers, cabling, switches, routers and software can all be expensive and should never be purchased without expert advice. Keeping the network operating and secure also requires a lot of resources and can be costly.

Surprisingly, a local area network can bring a number of cost savings. Sharing resources avoids the need to purchase equipment for each individual. Even more important is the security that a local area network can provide. Data loss could cost a business a great deal of money and in some cases, cause the business to shutdown altogether. Computer Network Management should require a consistent routine for data backups with regular checkups of data quality - a practice that will save a company huge sums in the event of a mishap.

Computer Network Management: preliminary analysis phases

The first phase of computer network management is to determine the source of the problem (a preliminary study that looks into several options of differing scope may be useful here) and defining it in a specification of requirements. Examples of what should be evaluated are different network operating systems, mail systems, and other applications. The choice of hardware components should also be evaluated. This phase is generally aimed at establishing what the system should do, not how it should do it.

Computer Network Management: design phase

The purpose of design phase is to determine how the requirements of the specification are to be met. The current approach to large, complex projects is to break them down into smaller, more manageable subprojects.

Computer Network Management: implementation phase

This phase involves the physical installation of the local area network. Cables are run, software is installed, and computers and other hardware are put in place.

Computer Network Management: integration and system testing phase

In this phase, commissioning of the network begins, and routines are adapted to users and the operating personnel. The system must be tested, both to ensure that the network meets the requirements set out in the specification and that it is stable enough to perform the central function it has in the organization.

Computer Network Management: operation and maintenance

Local area networks have complex operating routines. This is because there may be serious consequences when faults occur or unauthorized persons gain access to the system. Many companies have employees devoted solely to take care of running and maintaining computer networks. These system administrators may deal with network issues such as performance, reliability and security of both hardware and software.

Computer Network Repair

Computer networking is very important when it comes to in-house office jobs where the mutual connection of computers constitutes an important part of the whole work. Therefore, networking is an important element in today’s corporate world.

There are many professional technicians who have the to securely install whatever type of network you require. All networking vendors use the highest quality hardware and software to help insure that your network is trouble free so that you don't have to worry about it. They also troubleshoot and maintain existing networks in homes and offices.

Most technicians are friendly, professional and qualified and will do everything in their power to make servicing your computer or network a positive experience. This means speaking in non-technical, easy-to-understand terms and explaining exactly what's wrong, what your options are and what the estimated costs are. Computer network vendors and repairers provide support for all network platforms.

Of course, security should be your main concern. It should always be your number one priority when it comes to choosing a company to do your computer network repair. They should be fluent in all security program-related language, and should be able to communicate it in lay terms when needed. That way, you can work with them to decide what is the most efficient and least expensive route to take. However, do not skimp on this investment, for such skimping could hypothetically cost you your entire business in the long run.

10 tips for improving your wireless network

If Microsoft Windows XP ever notifies you about a weak signal, it probably means your connection isn't as fast or as reliable as it could be. Worse, you might lose your connection entirely in some parts of your home. If you're looking to improve the signal for your wireless network, try some of these tips for extending your wireless range and improving your wireless network performance.

1.	Position your wireless router (or wireless access point) in a central location. When possible, place your wireless router in a central location in your home. If your wireless router is against an outside wall of your home, the signal will be weak on the other side of your home. Don't worry if you can't move your wireless router, because there are many other ways to improve your connection.
2.	Move the router off the floor and away from walls and metal objects (such as metal file cabinets). Metal, walls, and floors will interfere with your router's wireless signals. The closer your router is to these obstructions, the more severe the interference, and the weaker your connection will be.
3.	Replace your router's antenna. The antennas supplied with your router are designed to be omni-directional, meaning they broadcast in all directions around the router. If your router is near an outside wall, half of the wireless signals will be sent outside your home, and much of your router's power will be wasted. Most routers don't allow you to increase the power output, but you can make better use of the power. Upgrade to a hi-gain antenna that focuses the wireless signals only one direction. You can aim the signal in the direction you need it most.
4.	Replace your computer's wireless network adapter. Wireless network signals must be sent both to and from your computer. Sometimes, your router can broadcast strongly enough to reach your computer, but your computer can't send signals back to your router. To improve this, replace your laptop's PC card-based wireless network adapter with a USB network adapter that uses an external antenna. In particular, consider the Hawking Hi-Gain Wireless USB network adapter, which adds an external, hi-gain antenna to your computer and can significantly improve your range. Laptops with built-in wireless typically have excellent antennas and don't need to have their network adapters upgraded.
5.	Add a wireless repeater. Wireless repeaters extend your wireless network range without requiring you to add any wiring. Just place the wireless repeater halfway between your wireless access point and your computer, and you'll get an instant boost to your wireless signal strength. Check out the wireless repeaters from ViewSonic, D-Link, Linksys, and Buffalo Technology.
6.	Change your wireless channel. Wireless routers can broadcast on several different channels, similar to the way radio stations use different channels. In the United States and Canada, these channels are 1, 6, and 11. Just like you'll sometimes hear interference on one radio station while another is perfectly clear, sometimes one wireless channel is clearer than others. Try changing your wireless router's channel through your router's configuration page to see if your signal strength improves. You don't need to change your computer's configuration, because it'll automatically detect the new channel.
7.	Reduce wireless interference. If you have cordless phones or other wireless electronics in your home, your computer might not be able to "hear" your router over the noise from the other wireless devices. To quiet the noise, avoid wireless electronics that use the 2.4GHz frequency. Instead, look for cordless phones that use the 5.8GHz or 900MHz frequencies.
8.	Update your firmware or your network adapter driver. Router manufacturers regularly make free improvements to their routers. Sometimes, these improvements increase performance. To get the latest firmware updates for your router, visit your router manufacturer's Web site. Similarly, network adapter vendors occasionally update the software that Windows XP uses to communicate with your network adapter, known as the driver. These updates typically improve performance and reliability. To get the updates, visit Microsoft Update, and then under Select by Type click Hardware, Optional. Install any updates relating to your wireless network adapter. It wouldn't hurt to install any other updates while you're visiting Microsoft Update, too. Note When you go to Microsoft Update, you have two options: the Express Install for critical and security updates and Custom Install for high priority and optional updates. You may find more driver updates when you use Custom Install.
9.	Pick equipment from a single vendor. While a Linksys router will work with a D-Link network adapter, you often get better performance if you pick a router and network adapter from the same vendor. Some vendors offer a performance boost of up to twice the performance when you choose their hardware: Linksys has the SpeedBooster technology, and D-Link has the 108G enhancement.
10.	Upgrade 802.11b devices to 802.11g. 802.11b is the most common type of wireless network, but 802.11g is about five times faster. 802.11g is backward-compatible with 802.11b, so you can still use any 802.11b equipment that you have. If you're using 802.11b and you're unhappy with the performance, consider replacing your router and network adapters with 802.11g-compatible equipment. If you're buying new equipment, definitely choose 802.11g. Wireless networks never reach the theoretical bandwidth limits. 802.11b networks typically get 2-5Mbps. 802.11g is usually in the 13-23Mbps range. Belkin's Pre-N equipment has been measured at 37-42Mbps.

4 steps to set up your home wireless network

You can use a wireless network to share Internet access, files, printers, and more. Or you can use it to surf the Web while you're sitting on your couch or in your yard. Plus, it's easier to install than you think.

There are 4 steps to creating a wireless network:

1. Choose your wireless equipment

2. Connect your wireless router

3. Configure your wireless router

4. Connect your computers

For Windows XP users, Windows XP Service Pack 2 is not required for wireless networking, but it does make things much easier. Service Pack 2 also helps protect you against hackers, worms, and other Internet intruders. To install Service Pack 2, visit the Protect Your PC site.

Choose your wireless equipment

The first step is to make sure that you have the equipment you need. As you're looking for products in stores or on the Internet, you might notice that you can choose equipment that supports three different wireless networking technologies: 802.11a, 802.11b, and 802.11g. We recommend 802.11g, because it offers excellent performance and is compatible with almost everything.

Shopping list

•Broadband Internet connection

•Wireless router

•A computer with built-in wireless networking support or a wireless network adapter

A wireless router

The router converts the signals coming across your Internet connection into a wireless broadcast, sort of like a cordless phone base station. Be sure to get a wireless router, and not a wireless access point.

A wireless network adapter

Network adapters wirelessly connect your computer to your wireless router. If you have a newer computer you may already have wireless capabilities built in. If this is the case, then you will not need a wireless network adapter. If you need to purchase an adapter for a desktop computer, buy a USB wireless network adapter. If you have a laptop, buy a PC card-based network adapter. Make sure that you have one adapter for every computer on your network.

Note: To make setup easy, choose a network adapter made by the same vendor that made your wireless router. For example, if you find a good price on a Linksys router, choose a Linksys network adapter to go with it. To make shopping even easier, buy a bundle, such as those available from D-Link, Netgear, Linksys, Microsoft, and Buffalo. If you have a desktop computer, make sure that you have an available USB port to plug the wireless network adapter into. If you don't have any open USB ports, buy a hub to add additional ports.

Connect your wireless router

Since you'll be temporarily disconnected from the Internet, print these instructions before you go any further.

First, locate your cable modem or DSL modem and unplug it to turn it off.

Next, connect your wireless router to your modem. Your modem should stay connected directly to the Internet. Later, after you've hooked everything up, your computer will wirelessly connect to your router, and the router will send communications through your modem to the Internet

Next, connect your router to your modem:

Note: The instructions below apply to a Linksys wireless router. The ports on your router may be labeled differently, and the images may look different on your router. Check the documentation that came with your equipment for additional assistance.

If you currently have your computer connected directly to your modem: Unplug the network cable from the back of your computer, and plug it into the port labeled Internet, WAN, or WLAN on the back of your router.

If you do not currently have a computer connected to the Internet: Plug one end of a network cable (included with your router) into your modem, and plug the other end of the network cable into the Internet, WAN, or WLAN port on your wireless router.

If you currently have your computer connected to a router: Unplug the network cable connected to the Internet, WAN, or WLAN port from your current router, and plug this end of the cable into the Internet, WAN, or WLAN port on your wireless router. Then, unplug any other network cables, and plug them into the available ports on your wireless router. You no longer need your original router, because your new wireless router replaces it.

Next, plug in and turn on your cable or DSL modem. Wait a few minutes to give it time to connect to the Internet, and then plug in and turn on your wireless router. After a minute, the Internet, WAN, or WLAN light on your wireless router should light up, indicating that it has successfully connected to your modem.

Using the network cable that came with your wireless router, you should temporarily connect your computer to one of the open network ports on your wireless router (any port that isn't labeled Internet, WAN, or WLAN). If you need to, turn your computer on. It should automatically connect to your router.

Next, open Internet Explorer and type in the address to configure your router.

You might be prompted for a password. The address and password you use will vary depending on what type of router you have, so refer to the instructions included with your router.

As a quick reference, this table shows the default addresses, usernames, and passwords for some common router manufacturers.

Router Address Username Password

3Com http://192.168.1.1 admin admin

D-Link http://192.168.0.1 admin

Linksys http://192.168.1.1 admin admin

Microsoft Broadband http://192.168.2.1 admin admin

Netgear http://192.168.0.1 admin password

Internet Explorer will show your router's configuration page. Most of the default settings should be fine, but you should configure three things:

Your wireless network name, known as the SSID. This name identifies your network. You should choose something unique that none of your neighbors will be using.

Wireless encryption (WEP) or Wi-Fi Protected Access (WPA), which help protect your wireless network. For most routers, you will provide a passphrase that your router uses to generate several keys. Make sure your passphrase is unique and long (you don't need to memorize it).

Your administrative password, which controls your wireless network. Just like any other password, it should not be a word that you can find in the dictionary, and it should be a combination of letters, numbers, and symbols. Be sure you can remember this password, because you'll need it if you ever have to change your router's settings.

The exact steps you follow to configure these settings will vary depending on the type of router you have. After each configuration setting, be sure to click Save Settings, Apply, or OK to save your changes.

Now, you should disconnect the network cable from your computer.

Connect your computers

If your computer does not have wireless network support built in, plug your network adapter into your USB port, and place the antenna on top of your computer (in the case of a desktop computer), or insert the network adapter into an empty PC card slot (in the case of a laptop). Windows XP will automatically detect the new adapter, and may prompt you to insert the CD that came with your adapter. The on-screen instructions will guide you through the configuration process.

Note: The steps below only apply if you're using Windows XP Service Pack 2. If you're running Windows XP and you don't have Service Pack 2 yet, plug your computer into your wireless router and download and install Service Pack 2 from the Protect Your PC site.

Windows XP should show an icon with a notification that says it has found a wireless network.

Follow these steps to connect your computer to your wireless network:

Right-click the wireless network icon in the lower-right corner of your screen, and then click View Available Wireless Networks. If you run into any problems, consult the documentation that came with your network adapter. Don't be afraid to call their tech support.

The Wireless Network Connection window should appear and you should see your wireless network listed with the network name you chose. If you don't see your network, click Refresh network list in the upper-left corner. Click your network, and then click Connect in the lower-right corner.

Windows XP prompts you to enter a key. Type the encryption key that you wrote down earlier in both the Network key and Confirm network key boxes, and then click Connect.

Windows XP will show its progress as it connects to your network. After you're connected, you can now close the Wireless Network Connection window. You're done.

Note: If the Wireless Network Connection window continues to show Acquiring Network

Address, you may have mistyped the encryption key.

Computer Network Securities

Computer security policies are the basic guidelines and rules for accessing a network. These lay out some basic concepts to secure your computers. Computer network security is a complicated area, and is taken up by experts with many years of on-the-job experience.

As more people turn to computers for simplifying their day-to-day activities and jobs, the need for general users to understand the concepts of network security has become important. One should know the risks involved in using the computer without the security systems, and learn how to deal with them successfully both at home and at work.

There are two popular types of network security systems: transit security and traffic regulation systems. When both of these join forces you can be assured of the delivery of important information to the right person without any network pilferage problems. The receiver should also ensure that the information received should be carefully processed using a computer which is loaded and protected with latest protection software.

The simplest form of ensuring security on the net is to keep a close watch on the type of data packets moving between the networks. If an infected packet does not reach the recipient, the host may have nothing to worry about. Traffic regulation systems serve as a protective screen between the receiver and remote sites. These tools generally guards three basic regions of the network: the routers, firewalls and hosts.

The three ‘guards’ deliver similar service at various points in the network, and it is difficult to draw a differentiating line between them. The truth is that there are no foolproof systems which offer a guaranteed secure system for data transferred in the public network. With the increasing use of the Internet, network security is fast becoming crucial for the safe use of the systems, and therefore computer network security is all set to be an important part of our regular computer usage.

WHAT IS NETWORK?
A computer network is simply computers wired together in a way that lets them share data and/or devices such as hard drives, CD-ROMs, fax-modems, printers, etc. Since you can share hard drives on a computer network, a smaller drive can reside on each computer with a single large drive on the system that shares the data area with all users.

If you own multiple PCs, you have probably thought about how great it would be if your computers could talk to each other. With your computers connected, you could:

1. Share a single printer between computers


2. Share a single Internet connection among all the computers in your home and small office.


3. Access shared files such as photographs, MP3s, spreadsheets and documents on any computer in the house and small office.


4. Play games that allow multiple users at different computers


5. Send the output of a device like a DVD player or Web cam to your other Computer(s)

Networking Basics
To install a network in your home or small office, there are three steps:

1. Choose the technology you will use for the network. (Standard Ethernet, Phone –line –based, power-line-based and wireless).


2. Buy and install the hardware.


3. Configure the system and get everything talking together correctly.

Note: Step 3 is extremely important. It is also very educational, if you understand the configuration process; you understand everything a home and small office Network is capable of doing for you.

In today's business world, reliable and efficient access to information has become an important asset in the quest to achieve a competitive advantage. File cabinets and mountains of papers have given way to computers that store and manage information electronically. Coworkers thousands of miles apart can share information instantaneously, just as hundreds of workers in a single location can simultaneously review research data maintained online.

Computer networking technologies are the glue that binds these elements together. The public Internet allows businesses around the world to share information with each other and their customers. The global computer network known as the World Wide Web provides services that let consumers buy books, clothes, and even cars online, or auction those same items off when no longer wanted.

In this guide, we will take a very close look at networking, and in particular the Ethernet networking standard, so you can understand the actual mechanics of how all of these computers connect to one another.

Advantages of Networks:

1. Being easy to set up new users and equipment


2. Allowing the sharing of resources


3. Ease of administering users


4. Ease of administering software licenses


5. Allowing electronic mails to be sent between users


6. Allowing simple electronic access to remote computers and sites


7. Allowing the connection of different types of computers, which can communicate with each other.

Disadvantages of Networks:

1. One server breaking down may affect a number of computers.


2. Vulnerable to hackers and viruses.


3. Cabling and installation may be expensive.


4. A network manager may need to be employed to run the network.

Types of Network

1. Peer-to-peer networks: All computers are of equal importance. Software and data are stored on each computer. Peer-to-peer networks have workstations connected to each other but do not have servers. Files can be shared between workstations, and a printer connected to one workstation can be accessed by another workstation. Peer-to peer networks are often much simpler to set up than client/server networks. However, they lack some of the advantages normally associated with networks such as centrally managed security and ease of backing up files. Peer-to-peer networks would really only be set up among a few computers within an office or single room.

1. Client/Server network Software and data are held on a file server and may be used by other computers on the network. Client/server networks consist of two kinds of computer. The clients are usually computer workstations sitting on the desks of employees in an organisation. The servers are usually more powerful computers and are held in a central location or locations within an organization.

Ways to Connect (Technology).You can connect your home computers in a variety of ways:

1. Run cables across the floor between computers in the same room.


2. Install some form of wireless networking.


3. Link your computers through your phone lines.


4. Link your computers through your power lines.

If you have a network in your home or office, there are several different ways to connect the computers on your network together.

• WiFi Network: WiFi is the wireless way to handle networking. It is also known as 802.11 networking and wireless networking. The big advantage of WiFi is its simplicity. You can connect computers anywhere in your home or office without the need for wires. The computers connect to the network using radio signals, and computers can be up to 100 feet or so apart.

• Phone-Line Network: Phone-line networking is one of several ways to connect the computers in your home. If your computers are in different rooms, then phone line networking could be a good solution for you.

Power-Line Network: Power-line networking is one of several ways to connect the computers in your home. It uses the electrical wiring in your house to create a network.
