Introduction

With networks becoming more and more common in today's world the setup of these popular projects are also becoming easier. One trick that I have adopted is learning the basics as to how networks work then jump right into them. If I come into any problems then you can always call the support line or call a friend. After a while you will notice that researching how protocols work and why the work, you will see that networking becomes much easier to perform and troubleshoot. This is of cores dangerous for people who are thinking of making networking their profession but perfectly fine for people who are considering a network as a weekend project.

Creation

   First of all you need two computers with a distance of no greater than 300 feet between them. Second you probably want to have the networking equipment which includes two Network Interface Cards (NIC), two RJ45 cables, "todays standard in the year 2000", a Hub or Switch, and some time on your hands. 99% of the time the network card will be plug and play which just makes things so much easier because then it is just a matter of hardware and protocol setup.
   Getting back to the NIC sometimes in those weird instances you will have to use a utility on a floppy disk that comes with the card. The instructions will also come with the card to assist you in this process.
   The other components of a network are the cables and the Hub/ Switch. The standard RJ45 cable is used to connect the computers to one another,

the majority of networks use a hub or a switch to rout the information in between two or more computers.

Connections

Looking at the hub above you will see that there are five RJ45 connectors and one BNC connection. The BNC connection is a primitive type of network setup that uses only one cable and each computer on the network has a T connection to this one wire.

It is a cost affective network but the bandwidth is very low compared to other networks and the parts are hard to find in today's world. Looking at the RJ45 connections, the connection furthest to the right is the up-link. The up-link is often used for the Internet or network input but in reality any of the connections can serve the same purpose. The next one over "to the left" you will see that it is the 1X, in most hubs this is considered to be the same wire as the Up-Links and requires a special cable known as a crossover for there to be any kind of data transfer. In most cases the 1X is just ignored and connections 2x through 4x and Up-Link are used.

Conclusion

So here we are with two or more computers connected to the network but nothing is really happening. Well this is where networking becomes fun, from here what you do is install the protocols such as TCP/IP and IPX/ SPX for game play as well as file and printer sharing so that other computers can use your resources. Also after you completely setup your network you will be able to share the internet between computers so that everyone in your office can use e-mail and chat clients.
