Setting up a Network — Wired or Wireless?

November 19th, 2009



To Wire or Not to Wire

Wireless networks are en vogue, but your installation won’t be successful unless you chose the right type of network and set it up properly. Wired networks require that each computer be connected via a wire to a central location, called a switch or hub. This often involves installing cables through walls and ceilings and can present a challenge for anyone.


If the computers in your home or office are all within 500 feet of each other, a wireless network might be for you. A wireless network has no cables. It can connect computers on different floors of a building or even across the street. Aside from the obvious benefit of not having wires, wireless networks are more convenient since the setup, configuration, and reconfiguration can often be done within minutes, without extensive planning.


Wireless networks, however, are not as fast as wired networks. If you play computer games or want to view streaming video or other high-speed multimedia, a wireless network might not have enough capacity. But, if you just want to check e-mail and view web pages, a wireless network is a good choice. To install a wireless network, you need a Wireless Access Point and a wireless network card for each computer. You will need to buy a wireless network card for each desktop computer, although most newer laptops come equipped with one.


Security is not a large concern in a wired network, since someone would have to physically connect to a wired network to break in. In wireless networks, a car parked outside with a laptop could easily connect to your network if you don’t have proper security in place. To prevent this from happening, encrypt your wireless network connections, or set a password to access the network, or do both.

Do It Yourself or Call a Professional?

If you decide to use a wired network, consider whether you will install it yourself or hire a professional. If you have a small number of computers that are all situated very close to one another, you may be able to buy pre-assembled network cables and connect them yourself. If you need to wire multiple floors and lay wire through ceilings and walls, you need a professional installation. If you go this route, it is best to begin with a floor plan of your office or home, determine what your current needs are, and consider how the network design can be adapted to future needs. A professional installer should be familiar with EIA/TIA standards, local wiring and electrical codes, and making custom cables. Network cabling professionals are often judged by the neatness of their work, because sloppy cabling is more apt to deteriorate over time, harder to manage, and poses more of a fire risk.


Having a wireless network or a wired network is not mutually exclusive. Many small offices have a wired network in addition to one or more wireless networks, depending on their needs. Wireless networks are continuing to get faster, more secure, and less expensive. Wired networks will continue to coexist with wireless networks, often in the same homes and offices.

Do You Have Two Or More Computers in Your House? Create a Network in Your Home and Share Resources

November 18th, 2009



So the journey begins and our first stop is to establish the basics of a network. This Basic Networking guide will help you understand the following:

• The Hardware used to create a network
• The correct operating system to use on our network
• Understanding how networks work

So buckle up your seatbelt, here we go! Are home networks Complicated to set up? The short answer to the heading above is No. The long answer… Heck no!

Believe it or not, setting up a network in your home is not complicated by any means. All you need is a point in the right direction and a little guidance. Together with this Basic Networking guide we will create the best network for you and your family.

So, what’s a network?

Simply put, a network is when two or more computers are connected and sharing data. That’s it! Nothing more, nothing less. These computers can be connected in a variety of ways and we will touch on that a little later. What we want to do now is work out the type of network we need in our house.

Why do I need a network again?

There are a lot of benefits to having a network. If you have more than one computer in your house you really have no reason not to have them networked, and by networking them you will be able to:

• Share printers, CD-ROM drives and other removable drives between the computers.
• Eliminate having to transfer files from one computer to another using a floppy (do they still exist?) or CD-ROM and share files directly between PCs. ( a great advantage if you are lazy like me)
• A huge benefits is you can share your internet connection with the other computers in your home
• Store only a single copy of large files, saving space on the other PCs’ hard drives.

Fantastic, how do I get started? Whoa there! Before we can start anything we need to plan first. “Plan?” I hear you say. Yes, plan! Building a network is a kin to building a house; we need a strong foundation to build upon. I can hear the groans already! You will be thanking me later.

There are two types of schemes you can use in a Network; Client/server network and peer to peer.

In the client/server network, you have one computer that acts as the server (the manager of the network or files), which controls the way other computers (known as clients) access the network, whether that being file sharing or running a program. Servers play a very important role on this particular type of network

Most home networks are based on the peer to peer Network, which has more relaxed controls thus is a better network for you and your family.

Operating Systems

This basic Networking guide assumes your operating system (OS) is at the very least windows 98 Second Edition. Although Windows XP would be preferable it’s not a requirement. The reason for this is because networking was built to function from the ground up in windows 98 SE to windows XP. The following OS will work perfectly with networking:

• Windows XP
• Windows 2000
• Windows NT
• Windows ME
• Windows 98 SE (Second Edition)

Also all these OS versions have a pretty little nifty tool on them known as Internet Connection Sharing. This allows all computers to share the internet, so while you are reading an e-mail on your laptop, your kid can be checking out their facebook page on the PC.

Each computer must have a Network interface card otherwise known in short form as a NIC. Traditionally a NIC is a little electronic card that goes inside your computer right on its mother board, I use the term traditionally as not all NICs are cards anymore, and we now have network adapters that are connected via USB (Universal Serial Bus).

How to Connect – Cables, wires or thin air?

Now we must decide the type of connections we will use to connect our computers. This is very important as the type of connection we use will affect the speed that data travels across the network. Why is speed important? Well waiting a long time for a file to open in a software application or for a file to be copied from one machine to another can be very frustrating to put it mildly. We have four different ways to connect our PC’s, each have their own advantages. Let’s look at them shall we?

Ethernet Cables

• The connection type of choice for many businesses. Fast and reliable
• Can carry data up to1000 mbps across a network depending on the rated speed of the NIC cards
• Used by most businesses to connect their computers
• Though similar looking to telephone wire, it is designed to carry data unlike telephone wire which was designed to carry voice
• You will need a concentrator (we will get to this later,) to use Ethernet cable.
• The connector at the end of the cable looks like the connector at the end of your telephone cable, but it’s actually slightly fatter.

Telephone Line

• Connect each computer’s NIC (has to be a Telephone-cable NIC. Have you visited the NIC page yet?) to the telephone wall jack using a regular phone cable.
• Telephone cable is inexpensive and is available every where, including your super market
• Networking process uses part of the line voice communication doesn’t, so you can still make calls whilst on the network
• Can transmits data up to 10mbps
• Is increasing with popularity.
• You will need a splitter for telephone wall jacks, to use your phone in the same jack
• If you have multiple lines in your house, all computers must be connected on the same line (same number)

Wireless connections

• No wires to trip over
• A very popular choice
• Best used on Windows XP, so would be best option to have all PC running XP
• Requires network adaptor that can receive and send wirelessly.
• Frequency can travel roughly 150 feet, passing through ceilings, walls and floors.

Setting Up a Home Networking System

October 17th, 2009



Since Microsoft released Windows for Workgroups, networking has become quite easy and very commonplace for most home computer users.  Everything that is needed to set up a home network is built right into the computer’s operating system which was installed in the machine.  All you have to do is turn it on and set it up.  If you happen to have Windows 95/98 setting up a network is a snap!

A home network is, simply put, a made up of set of hardware and also a set of software that will allow computers to communicate with each other.  A home network enable File sharing or using the same printer or other input and outputs instead of buying one for each available computer.

A home network functions in almost the exact same way as that used by a private businesses when a LAN or Local Area Network is created.  Designations, or IP addresses, as well as some that are catchy phrases that humans will remember are called host names and they know who everyone is as well as where everything is. Let’s say that 10.1.1.5 or Computer Jack sends a file to 10.1.1.6 or Computer Jill.  The hardware and software must cooperate with each other in order to know where and how to send the file from Jack to Jill.

This idea is much the same as that used by the post office.  There is an address associated with each home.  A letter that is sent from one home is routed to another by using that address.  Putting the return address on the letter is very important so the person knows where to respond. Also, if the letter gets lost, it will be sent back to the return address.  If there is no return address it just goes to the dead letter office.   Home computer networks work in much the same way.

The routing data is also known as ‘an envelope’.  This surrounds the data or the words on the letter. A home network comes in two main types:  cabled and wireless. In a cabled network different wire bundles which are known as Ethernet cables with connectors on each end plug into either a network interface card, or NIC, in the printer, fax, computer or into a switch/router.  Hubs or switches are simplified devices that allow physical connections between the components of a network.

A wireless network operates in much the same way.   The main difference is that there is no need for cables.  Small devices known as transceivers send and retrieve information by radio signals. Let’s say that you want two computers within a home network to both be able to print on the same printer.  Where would you even start to do something like that?  You can make this happen in two possible ways.  In one set up, the printer is physically attached to one of the computers.  The alternate set up connects the printer to the network and not to any individual computer;

With this first arrangement, the printer is called local, but shareable.  It is possible to allow a remote computer to print to the locally attached device.  Computer-Jack then just shares the printer by using software of the hosting system, Computer Jill. In most typical cases nowadays, the printer has its own NIC.  It is then attached to a router or switch by way of Ethernet cables or a wireless transceiver.  Then each computer on the network is able to ’see’ the printer as a device that the computer can use.

Scanners, fax machines and other computers operate in pretty much the same way.  Every device receives an address and a name.  Software on the device allows it to be configured so that its function is accessible to multiple computers on the same network.
