Q.
Where
did it all start?
|
|
A.
The
forerunner of today's Internet was born of an experiment started
in the 1960's. The U.S. Department of Defence created a network
called ARPANET which linked U.S. scientific and academic researchers.
The idea was to create a network, which would continue to
function in the event of a nuclear war or natural disaster.
If part of the network were taken out of the picture the rest
would continue to work!
In
the mid 1980's NSFNET came along as a series of networks
for research and education communication. These networks
were built on ARPANET protocols and provided a free backbone
service to any U.S. research and educational institution.
Simultaneously, regional networks were created to link these
institutions to the national backbone.
The
whole thing grew pretty rapidly from there as commercial
companies first started linking to the NSFNET backbone,
and then ultimately took over the operation.

Q.
What
exactly is a Web site?
|
|
A.
In short it's a collection of files in a folder
or folders. They are made up mostly of HTML files, theses
are the Web pages, and GIFs and JPGs, the picture or graphics
files. These folders have a Web address, otherwise known as
a URL attached to them e.g 'www.mymatedave.co.uk'. When you
type that address into your broswer, you are viewing the files
contained in that folder.

Q.
What's HTML then?
|
|
A.
HTML
stands for 'Hyper Text Mark-up Language' It's a cross platform
computer language layed out with "tags," that
instruct a web browser how to display a hypertext document.
Before HTML came along, the Internet was pretty much e-mail
based i.e. simple text messages with little of no formatting.
HTML blew the lid off this and led to the explosion of the
World Wide Web.

Q.
So
if I want to make Web pages, do I have to learn a computer
language?
|
|
A.
No,
although a little dabble may be of use in the long run.
In the old days we did all our HTML coding by hand in notepad.
These days you'd use Web editing software. With a Web editor
you can see what you are doing as you go along. If you want
your page background yellow you click 'background.. yellow'.
The HTML is all going on in the background. You end up with
the same result but you never need know what an HTML tag
even looks like. These days. It's a doddle.

Q.
What's
the difference between a GIF and a JPG
|
|
A.
Internet
browsers such as Netscape and Explorer view two different
image file types. These are JPG's and GIF's. these are both
compression formats designed with file size in mind. They
both use a different method of compression and a basic understanding
of this will help you decide which is right for each particular
graphic you prepare.
In
short, and this is all you really have to know, GIF's
compress the file size by reducing the amount of colours
in a picture or graphic, a GIF can be between 2 colours
(black & white and 256 colours (some graphics software
only gives you the choice between 2,16 or 256 colours).
JPG's always use the 16 million colour palette but reduces
file size by blurring areas of similar colour together
and remembering these blocks, rather than each individual
pixel.
GIF's are best
suited to spot colour graphics for example text or simple
logos. JPG's are best suited to photographic images. These
aren't hard and fast rules but will save you lot of time
experimenting.

Q.
When
I'm building a Web page, when would I use tables?
|
|
A.
All
the time. Using tables you can choose pretty much exactly
where you want things to appear on your Web page. You can
change the background colour of your table and the background
colour of the cells within it. This can be used to great
effect to add a little design and colour to your page without
requiring the download of hefty graphics for example on
this page, the blue bars under these questions and the blue
column and menu to the left.

Q.
What's
USENET
|
|
A.
Basically
it's a huge information exchange forum made up of specific
groups of special interest. The whole thing is made up entirely
by contributions, or postings from it's users.
There
are approximately 20,000 different areas, called newsgroups
available within this massive modern day phenomenon.
It's
a researcher's dream, if there's something you want to
know ask those helpful people on Usenet. The are hundreds
of thousands.. no millions of informed people just waiting
to share their specific knowledge with you, and all you
have to do is ask! Politely that is!! And it's all free!!!
This is the place to shout you message to the world at
the top of your voice. Here you can let your own personal
feelings be known and hear the views of others.
In
short it works like this.. you find the newsgroup title
which looks closest to fitting the bill for what you want
to learn or say. You sign on to it using your mail software,
and every time you go on-line all the postings to that
particular group are downloaded by you to read off-line.
In your own time, you make your reply to previous postings,
or start a new subject line, called a thread, and next
time you go on-line, your posting goes off and all the
new ones come back.
It's
usually a good idea to read the postings only for a few
days when you sign on to a new group, this is to get the
feel of it as they all seem to hold their own character.
Hanging around like this is called lurking and feels like
listening to a telephone chat line without speaking but
in this case it's a good idea to do it. You want your
posting to get a favorable reply and it's not a good idea
to upset anyone if you can help it.

Q.
How
do I get my site to come up in the search engines
|
|
A.
There
are many different ways of publicising or 'propagating'
your site on the Internet itself. A good place to
start is with the major searchers
and indexes. If you are looking for information
on the web, but don't have an address to follow,
searches and indexes would be natural places to
start looking. It therefore follows that you should
let them know of your existence so that they may
lead people to you.
Most
searches have an option to submit your URL. This
is relatively easy, but can be very time consuming
as there are many such engines, some faster and
more efficient than others. Before you start,
have descriptions, key words, URL, and e-mail
address typed up and ready to cut and paste to
save time online.
A
good way of getting searches to find and recommend
your site is with the use of 'meta-tags' with
a list of key words and description that best
describes your site. This is hidden within the
source code of your page and is not displayed
in the browser.

more to come on this page.. Come again soon.
