Session One.
INPUTS:
Keyboard.
This is one of your two most commonly used pieces of equipment. It has a
standard typewriter layout plus loads of weird keys that you have never seen
in your life. Please don’t worry too much about them right now. Even I
don’t know what they all do, and I have made a good living out of computing
for the past 45 years.
How competent you will become is entirely a
personal thing. I have seen people twinkling away with all ten fingers
within a couple of weeks, while others become two-finger merchants. It
doesn’t matter how fast or how slow you are – the computer is a very patient
thing, and it will be quite happy to wait until you have finished.
Mouse. A mouse is used to
pick out parts of your Windows program, and to start off smaller
sections. It will take you a few minutes to get used to using one, but
once you have found out what it does and how it works, you will wonder why
you didn’t try before.
Floppy Disk Drive. This is
where you insert small programs or files on small 3 ˝” plastic squares.
They are rarely found on modern PC’s, and you probably wont ever use them.
Hard Drive. This piece of
equipment is something you will never see unless you take the cover off your
PC. It is where all of your programs are stored, all of your love
letters, all of your personal stuff. It is also where the
Windows
program is stored, and the CPU is continuously reading and writing
to it. As long as you know it is there and what it does, there is no need
for you to worry about it. It looks after itself.
CD-ROM Drive. You know what
a music CD looks like? Well, that fits into the CD-ROM drive, and will
play perfectly well (providing you have speakers fitted). It is also the
way you will install new programs when you buy them from your friendly
computer shop.
One little tip….. when you remove a CD
from the CD-ROM Drive, always close the door. If you leave it open, it
is so easy to bash it off when you swing your chair around – then you have
to buy a new one!
Modem. “A what?” I
hear you cry. Please don’t worry. A modem is a
gismo that allows your home PC to connect to a telephone line (or cable
if you are disgustingly rich). You may have heard a horrible
screeching sound over your telephone from time to time; it
was probably a facsimile machine. That sound is the language
of a Modem. The Modem’s job is to send and receive computer
signals so that they can go over a telephone line
Other Bits ‘n Pieces.
Again, don’t worry too much about these right now. I could have mentioned
Scanners, Digital Cameras, IPods… There are lots of things that people
have invented for you to spend your hard-earned money on, but don’t really
need. We shall talk about them at the end of the course.

OUTPUTS.
Monitor.
Also known as a VDU (Visual Display Unit)
or simply as a Screen. You need to see what your home PC is up to, and
that is simply what your Monitor does. They come in all sorts of shapes
and sizes, including the new flat-screen jobs which are very expensive –
but very nice!
Printer. Printers are cheap
these days, but the ink cartridges are very expensive. That is how the
companies can afford to sell the printers so cheaply. I will tell you how
to keep the cost of ink cartridges down.
There is a new type of Printer available on
the market now which is a combined Printer, Photocopier and Scanner. They
are commonly referred to as a 3 in 1. They work out at about $100 a time,
but they take up very little space, and are ideal for plugging in a digital
camera if you have one. Please, do not buy one before talking it over
with me.
Speakers.
Depending on your needs, you should really have a minimum of two speakers,
but you can add a third base speaker, or really go up-market and get a set
of five, or even seven speakers. Some people like to watch DVD movies on
their PC’s, and that is when it is nice to have a very good sound system.
A pair of small speakers will be quite sufficient at this stage.
Hey – I have been doing all the work here
so far. Now it is your turn!
Please answer all of the following
questions. If you don’t know the answer, read back through these notes –
it is all there.
Then bring this sheet with you to the next
session. This will make sure that you do your homework! Good luck.
