And it has also organized
special music events in local clubs and private parties.
In the past the

father and son
have

r
u
n

the
ir
business using a simple cash register and paper based records. However,
due to recent increase in sales they want to invest in a proper computer system.

As you
will discover their knowledge on computers is very limited.

They’ve spoken to a few of
their
friends about this and you have been
recommended as

Letter from

Dear Sir/Madam

My name is
Angus

and
I

m writing to
ask for

your help in setting up a computer system for
our

business.
We
own

a
small
record shop called
Blue Moon

Musik
. My da
d (
Malcolm
) and I
need to improve our business by investing in a
new
computer system.
The business is mainly a
shop selling old music records and CD’s to the public, but I am also a part
-
time DJ and often
organise events at clubs.
Now, a
lthough I
might
h
ave a bit of knowledge about
computers my
dad doesn’t know the difference between a mouse and a monitor

so any work you do for us will
have to explain everything in detail
.

The problem we have at the moment is that everythin
g is done on paper. Paper label
s
, paper
receipts, paper accounts, I’m surprised the shop’s not made of paper!
Anyway, here’s what we
need:



A computer
to hold records
for all our customers, stock, and sales



Some software to help with the record keeping and accounts and some software to
produce
marketing material for my gigs


you know flyers, posters, etc



W
e might
also
n
eed some sort of printing facility to help with the advertising



Also
Malcolm

likes to collect and sell old records
and
he wants to make the record covers
available to see

electronically,
you know
so he can advertise them without having to ruin
the originals.

Can you suggest how we might achieve this?

I think that should be enough information to get you started. If you nee
d to ask me anything
just send us

an email
(the em
ail address is above
)
and I’ll get back in touch as soon as possible.
By the way there’s one more thing I forgot to mention. About two years ago my dad had a big
fire in the shop and all his accounts were destroyed, the police said that some youths had b
roken
in and stolen some of the customers account details too. We think that this new computer
system needs to be very safe to stop that from happening again. I’ll leave that one with you too.

Right then, I’m off to some
teachers’

birthday party


Mr.
Sm
ith

he said his name was. I’ll have
to dig out some of them “classics” from the
5
0’s. I’ll speak to you
soon;

hopefully you should
have something to show me next time.


Sincerely,

for both computer
systems you create.


b) Label each component to show which category it belongs to i.e input, processing,
output, storage.


c
)
Do some research to find realistic
costs

for the components
of

both

your computer

Step)


Following on from your recommendations
Malcolm

and
Angus

have now purchased a
computer system with a scanner and a printer. However, there are really struggling to get

:
Configure the Software



P6
, M3



As you may remember

Malcolm

now getting very old and he is quite conscientious about
his health. He has recently attended a computer health and safety class and would like
you to help make some necessary adjustments to his computer system to help him use it
better.


a)
Malcolm

is l
eft handed and so you must change the
mouse settings

so that
Malcolm

can use it with his left hand.

b)
Malcolm

suffers from Presbyopia (also know as being long
