Networks

Until recently configuring a computer network to enable it to talk to other computers or the outside world via the internet was always considered a black art! You need good knowledge of TCP/IP, DNS, IP etc.

However, today computer networks are reasonably straight forward and can be tackled by the home computer user.

To start with its useful to understand what equipment you will need. If you have purchased a broadband package then its likely that your ISP (Internet Service Provider) will have supplied you with a modem / router for you to plug your computer into. The modem/router then connects to the telephone point and enables your computer / laptop to become part of the internet! Most ISP's also provide a CD / DVD that auto-plays upon insertion and takes you through a simple set of screens (Wizard) that enables you to set up your computer to join the internet.

If your ISP did not supply you with a modem / router then these can be purchased from PC World and other similar retail outlets, the key is to be sure whether you want a wired connection e.g. once installed there is a physical wire connection between your computer and the modem / router or whether you would like more flexibility and would prefer a wireless connection which is ideal if you have a laptop.

A wireless connection enables your computer / laptop to connect to the modem / router via a wireless signal which is ideal if you want to use the internet in different rooms within your house. Wireless connections can sometimes be a little tricky to set up and it is essential to use the security features e.g WPA to ensure that your connection is secure and that other people with a WiFi enabled laptop can't access your network and ultimately your computer.

There have been recent press articles on how individuals have "stolen" bandwidth from an unsecured wireless connection by "piggy backing" onto your service and in some cases have then been able to access your computer without your knowledge and obtain private documents etc.

Wireless connectivity comes in various standards, 802.11g is the current standard but this is slowly being replaced with Pre N / Draft N which support a faster data transfer speeds. This will improve your internet experience and are ideal if you plan to download large files e.g. music or video.
