Internet - Glossary of Terms
IF YOU FIND THIS GLOSSARY USEFUL, PLEASE FEEL FREE TO PRINT IT OUT FOR FUTURE REFERENCE
- 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.
- Bounce:
- What happens to an E-Mail that's sent to an invalid address - basically it's
"returned to sender, address unknown."
- Browser:
- The program on your PC that enables you to interact with the World Wide Web.
The most popular ones are Netscape Navigator, and Microsoft's Internet
Explorer.
- Bug:
- A computer program fault.
- 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.
- Dial-Up:

provides access to the internet via their browser, and the facility of E-Mail, and
may provide some web space.

place their web pages, have an E-Mail facility, and statistical facilities etc.

messages by using punctuation marks; eg: :-)

- Hang-up:
- 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.
- Hardware:
- The part of a computer that you can see and touch. There are parts of the
computer which you can see, but which you shouldn't touch - but it's still
hardware. It's a bit like a woman.
- Header:
- The gobbledegook at the top of an E-Mail message that's automatically generated
by your E-Mail program. It tells you when the message was sent, to whom, by
whom, and which path it took through the net.
- Hex:
- Hexadecimal, is a method of counting that
programers use and is based on having 16 digits instead of ten. This
might seem odd, but is 2 to the power of 4. Counting starts at 0 to 9,
then a,b,c,d,e,f, with f representing 16, and f0 - 17 f1 - 18 etc, thus ff
you will find is 255.

When they arrive on your PC, they go into your In-Box.
- 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.
- Mime:

that users of different E-Mail programs can send files to each other.

- Perl:
- A program language that sits on the ISP web site, hidden below a web page that
performs a function such as a web page counter, or provides interactive form
mail, or creates dynamic web pages, creating them on the fly according to the
demands of the viewer - you. This is the most popular language although there
are others. Popular is not a good word in this context, because it's a terrible
language to have to get your head round, and there are as yet, no short cuts - this
is for programmers.
- Plug-In:
- Enhances the capability of your browser to enable it to play video clips,
animations, sound, etc.

don't propose to explain, except to say that the web is like an
encyclopedia of information - whatever you look up, you are likely to
find. For those who are concerned about what the kids might find,
there are programs available that will bar certain words from the

out there.

- The old fashioned "Royal Mail", - the post if you like.
