Bandwidth commonly refers to the amount of data that can be sent along a particular Internet connection (such as from your computer to your ISP or from your ISP into the Internet).
Computers within networks, including the global network of the Internet, operate within a client/server environment. Clients are software programs located on user’s computers and request information from servers (your web browser is an example of client software). Client software also presents the information to users in a user-friendly, point-and-click way. Server software, on the other hand, serves up information to the client and does all the donkey work and is written in programming language. The web servers run by ISPs are examples of server software.
These are small data files that certain web sites build up about your specific interests when you visit them and which they then store on your computer while you are connected with them. The next time you visit that particular web site, the first thing they do is to check whether they have sent you a ‘cookie’ before and if so, they check the cookie data file to see where you went and what you were interested in during your previous vist to their web site. Their site is then customised on the fly to address (or meet) these interests.

This stands for Integrated Services Digital Network and is a form of digital telephone connection instead of the standard analogue telephone lines most of us have at home. Because the telephone line is digital, you can send information down the line at faster speeds than across your standard line. You still need a modem – a digital modem – and Telkom will need to install and activate the digital line at your home or office. In addition, most ISPs can offer you ISDN access if you require. The cost is higher, but the service is faster and is worth considering if the Internet is likely to play an important part in your business or social activities.
