I myself have seen how quickly a network can grow. Here at iEntry, just a short six months ago when I began my tenure, we were working from six computers linked together as a peer-to-peer network. Now we have grown to above thirty computers, and with this growth has come many changes. Not only have we implemented a server but we are also in the process of migrating all of our systems to a Windows 2000 Server.

On another note, it seems that a few of our readers didn't like the fact that I was advocating Windows, but as I said that is where my expertise lies and you know what they say, "write about what you know". Now for my challenge, if you think the same as one reader who was upset about how I was praising "arch criminal Bill Gates" and his Microsoft Software, then write an article and send it to me. You can write about any operating system you like, as long as it is dealing with networking. I want you to make me see the error of my ways, show me that using OS X or Linux are better operating systems to use for a network.

In today's NetworkNewz, we will take a step back and begin at the basics. I will start a series of articles on how to design and build a network for your small business or home.

A network, in its simplest form, is two computers grouped together and linked to share resources. A resource can be a printer, Internet connection or files on one of the computers.

The two most common types of networks are Local-Area Networks (LAN's) and Wide-Area Networks (WAN's). Today's article is going to focus on the former, but first, a little information on just how a network is categorized.

There are three major properties that are used to categorize a network, they are: Topology, Protocol and Architecture. The Topology of a network is signified by the geometric arrangement of the network. A few common topologies are the bus, ring and star. The protocol specifies a common set of rules and signals that your computers will use to communicate across your network. The architecture of your network refers to being either a peer-to-peer or a client/server. A peer-to-peer network is one that has no server and the computers are connected to each other in a workgroup. Whereas with a client/server architecture, there is usually a central computer called a server, which all the other computers use as a controller for purposes such as: logon, print server and a centrally-routed access for an Internet connection.

If you have a small office, less than ten computers, your best bet would be to go with a peer-to-peer network. This will probably be the easiest and least expensive way to connect all of your computers. As mentioned above in a peer-to-peer network there is no server. All of the computers are simply connected together in a workgroup. In this workgroup you will find all your shared resources on your network.

Other than your computers, the first purchases you need to make will be your Network Interface Cards (NIC) and the cable to connect them together. If you are connecting more than two computers, you also need to purchase a hub. A hub is a hardware device that enables you to connect your computers together at a central location that will transfer your data packets to the destination computer. After you have all the NIC's installed on your computers and the cables connecting them you are ready to start configuring your computers to share the resources.

Next week we will find out how to go about configuring your computers so they can share files, printers and the ever-important Internet connection.
