**** MODEMS *************************************************** PAGE ********
MICRO COMMUNICATIONS - THE GUIDE
Even the humblest of home computers can be connected to the telephone system
and thence to some of the most powerful computers and biggest databases on
Earth. Linked in this way you can access phenomenal amounts of information or,
in a more practical sense, communicate with other computer enthusiasts
locally, nationally, or internationally.
`Hacking' is the popular term used to describe computer use of this sort.
And while it seems improbable that you could infiltrate sensitive databases
(though this has happened!) or trigger the next world war (which has only
happened in fiction), almost anything is possible. A computer, a
linking device called a MODEM, a telephone, and the appropriate, usually
very simple, software can quite literally open up the world!
Computers can communicate with each other in three basic ways. They can send
messages over long distances using telephone lines or radio waves (or in
some cases both). They can share the same information storage system (which
in practice means sharing the same disk units). Or they can be connected
directly and share each other's processor or memory.
HELLO WORLD
Of these options, the first is undoubtedly the most exciting, even thrilling,
step forward for the home computer enthusiast. It is already possible to
obtain equipment and software, at reasonable prices, which will enable your
computer to talk to another computer almost anywhere on the globe over the
very same `lines' which are used already for telecommunications.
Through the telephone systems, access to a huge range of facilities is
possible-from software exchange set up amongst groups of friends to huge
businesses, news and information services costing users several thousand
pounds a year.
Computer communications is one of those areas of new technology where the
future is really here today. By enabling one computer to talk to another
over long distances it is already possible to live and work from your own home
without ever stepping outside your front door.
You can peruse shopping lists, examine illustrations of the goods for sale,
compare prices and order what you want from your own armchair. You can control
your finances, pay prices instantly and keep an up-to-the-minute check on your
financial position. An increasing number of jobs can be done from home
using a micro, especially those office jobs which involve using and processing
information.
A secretary and boss, for example, could be miles apart in their own homes and
still work well together using computer communications. Having roughed out a
letter on his or her own micro the boss can send it, complete with spelling
mistakes and bad grammar, to the secretary, who then corrects it, formats it
so that it looks presentable, lets the boss have a quick check and, finally,
sends it.
BULLETIN BOARDS
A lonely life? Perhaps, but not necessarily. It is also possible to contact
other people with similar interests by computer. In some instances it doesn't
matter where in the world they are, the cost of contacting them could be as
little as a local telephone call. You can call up what is known as a bulletin
board to read messages left by other people and to leave messages yourself.
There are even bulletin boards set up for dating purposes!
If you decide to leave to leave the comfort of your own home and venture
outside you could book almost anything by computer-taxis, theatre tickets,
holidays, flights and much more besides.
Although there are many problems in linking up computers-caused mainly by the
failure of manufacturers to establish common standards-almost every week sees
another small breakthrough and every now and then there's a major
breakthrough. Much of this pioneering work is carried out at the grassroots
level by enthusiastic amateurs and students and their teachers at universities
and other higher education establishments.
The growth of interest in computer communications, and indications that it is
the next exciting area for exploration, are shown in the fact that more and
more bulletin boards are being set up.
You could, if you wanted to, set up your bulletin board. Some are set up be
companies, usually electronics companies, who provide some space for users
while using other space on the `board' to advertise their own goods and
services. Others have been set up by groups of computer enthusiasts and by
collages and universities and this is the area of fastest growth.
Although often usable at any time of day, bulletin boards run by hobbyists
tend to be geared towards evening use.
ARMCHAIR SHOPPING
Many people take the view that these uses of computer communications are so
far-fetched that they are likely to remain in the realms of science fiction
for many years to come. But everything described so far is possible today.
Some people are so familiar with armchair shopping and banking that they
regard it as a part of everyday life.
You can use your computer to access information about goods and prices at a
wide range of shops. Or you can buy the goods and services and pay for them
with little more than a few keystrokes on the computer. The `work' is done by
a large central computer. This holds all the information and carries out the
electronic transfer of money from the customers account to the shop's account.
TELETEXT AND VIDEOTEXT
You can link up to any of the growing number of teletext and videotext
services even with a small home micro as long as it and your television
set have been adapted properly. In the case of the UK's two current teletext
services ORACLE (run by the independent television companies) and CEEFAX
(run by the BBC) this means you have access to hundreds of pages of
information including program listings and programs that can be downloaded
directly into your computer. Direct downloading in this instance is usually
only possible with a BBC computer connected to a special teletext decoder.
