Unit abstract
Most IT practitioners will at some stage have to set up, use, customise and maintain a
computer system or systems. In order to do so effectively they will need to
understand the components that make up a computer system. The operating system
interacts with the hardware components in order to make a functioning machine. As
this relationship is so close, this unit develops skills in hardware components and the
operating systems. Although the Microsoft operating system currently dominates the
market, it is not the only operating system and learners should explore at least one
other.
There are many different manufacturers of computer systems and each manufacturer
will produce a wide range of models with different specifications. Deciding which
particular model is appropriate for a given situation depends on a variety of factors.
These are explored in this unit so that successful learners can make informed choices
when choosing and purchasing systems.
In terms of software, the operating system itself often provides utility programmes
that assist the user in managing the machine. However other third party software
utility programmes such as virus checkers are also used extensively. This unit
considers both types of utility software.
Computer users also need the skills required to set up and carry out routine
maintenance of computer systems. Although this unit does not cover extensively fault
finding and repair, it includes the basic maintenance skills that would normally be
expected of most computer users.
Learning outcomes
On completion of this unit a learner should
1 Understand the hardware components of computer systems
2 Understand the software components of computer systems
3 Be able to undertake routine computer maintenance.
