Glossary

Address Book:

A handy place to store the E-Mail addresses of the people you contact on-line. All popular E-Mail packages have them.

Applet:

Usually refers to a mini program on a web site that performs some interactive function like providing you with web form-mail, or creating animations.

Attachment:

A separate file that is sent with an E-Mail message, such as a word processing document or image.

Binary:

A method of counting when you only have two digits to work with instead of 10. Numbering starts at 0, 1, 10, 11, 100, 101, 110, 111, 1000. this represents 0, 1, 2, 3, 4, 5, 6, 7, 8. Computers count this way because as far as they are concerned, an electric current is either 'on' or 'off', and this is represented by 0 for off, and 1 for on. Thus computers count using a series of switches to determine 'how many'.

Binary File:

Usually a file containing an image or a sound bite.

Bit:

1 computer storage unit. 8 Bits make a Byte, 1024 Bytes make a Kilobyte, 1024 Kilobytes make a Megabyte, 1024 Megabytes make a Gigabyte, and 1024 Megabytes make a Terrabyte. 1024 seems an odd number, but in fact it is 2 to the power of 8.

Cache:

When you download a web page from the net, your browser stores the images and text in a file called a cache. The next time you want to download those images, the browser first looks in the cache to see whether you have already downloaded those items before, and if you have, it will load them from your PC's cache, instead of off the web, thus saving precious download time.

Chat:

Internet programs that enable you to "talk" to other net users in real time, instead of via E-Mail. The words that you type on the screen, are instantly displayed on the screens of other people logged on at the same time.

Cookies:

Usually harmless mini-programs that a web site will want to add to your PC with the usual intention of either enabling it to recognise you next time you visit, or to find out some information from your computer like who you are, so that it can provide information to the web site owner which he can harmlessly use for statistical information, or for spamming you with E-mail.

This is when a computer starts sulking, it is also referred to as going into an indefinite loop. We would call it loopy - and so it is. Humans also have hang-ups, and tantrums, and computer programmers, being human, thought it best to humanise computers by letting them have hang-ups too. Great isn't it. Makes you feel at home, and it is one thing that computers are good at.

Millennium Bug:

In the beginning, computers were huge, and their memory capability was small. Today the reverse is true. In the beginning the space on a timer microchip for holding such mundane routines as the date, was at a premium, so short cuts were used. Instead of a date being given eight figures such as 01011998, - First of January, 1998, - it was saved as 010198. This was fine until it occurred to the world to pass the millennium date. Any program that compares dates under the old program code will be confused because it will assume that 010101 comes before 010199, not realising that we are into the next millennium. Computer programs are basically stupid, and when they get confused, they go into an old fashioned sulk, and either produce nothing while they contemplate the problem which causes a hang-up, or produce unpredictable results just like a cantankerous child.
