![]() Let's begin with something that we are all reasonably familiar with: Telephones. We pick up the telephone, dial a number and somebody, somewhere, picks up their ringing telephone. You're connected. And you can converse for as long, or as short as you like. In much the same way, your computer can be used to connect to any other computer on the Internet. Provided of course you are connected via 1) a modem & telephone line, to a 2) Internet Service Provider (ISP). Each computer on the Internet has a unique IP address, like a telephone number, made up of a set of four numbers, separated by dots, eg: 195.70.70.130. To make our lives easier, this set of numbers has been assigned an "alias", or hostname. In our case ikhaya.co.uk, again separated by dots. Typing in either the number or the hostname, as the "Address" or URL that you want to access on the Internet, will yield, in the above examples, the Home Page of Ikhaya Design Studio. Test it here:

Finding Information on the Web
One of the oldest "Web Directories" around is the "NCSA - What's New Top 25", where Mountain Magazine was listed for the week of 17 - 21 June 1996. Unfortunately NCSA, the developers of "Mosaic", forerunner of other browsers, stopped this service at the end of June - having spawned a whole industry of "Cool Sites", "Hot Sites", "Site of the Day/Week/Month/Year", etc.
Another, very popular Web Directory, with daily accesses topping 3 million, is maintained by Microsoft. Called the "MSN Pick of the Week", three sites are selected each week, in each of six different categories, as a starting point for "surfers" of the web. And, you guessed it, Mountain Magazine was a previous pick! Other services on the Internet
Email allows for the sending of simple messages, or complete documents and bitmaps as attachments to the email message. If you were to send an email message to the author; and he were at his desk, and connected to the Internet, the email message will be available for him to read within a few seconds, or at most a few minutes. However, if he is not, then he will only get the message the next time he accesses his mailbox. Every email address on the Internet, is absolutely unique. (If they were not, then you may receive my mail! And I yours, etc.) To send someone an email message, you must know their email address. Made up of a Username plus the hostname and linked by the @ symbol. Thus, a typical email address may look like this: yourname@ikhaya.co.uk - provided of course you are a registered user of the host's email services. A number of "Directories" can be found on the Internet, such as Four11, WWW Rider's Yellow Pages, etc. At present these "directories" are dependent on you listing your specific information with them, but this may change in future, where Service Providers will automatically upload new email addresses to such directories. Another move afoot, is for email addresses to be included in Telephone Directories.
Usenet News is made up of a number of discussion groups, allowing for the exchange of information, by it's members, or interested parties.
For example, if you type artists & illustrators into the box below you will be connected to "DejaNews'" news-server, where a search will be performed for you through their database of "Usenet articles". (To return to this page, use the browser's BACK function!
The final Internet service that we'll discuss for now. The transfer of large volumes of information from one system to another is most often done by means of FTP. For instance, if you want to update your browser you may download either Internet Explorer or Netscape from their respective FTP sites. Or you may need an utility for your computer, or updated drivers for your printer or other peripheral device. Most of this information is transferred by means of FTP.
