UNIT 3
 

Unit 3: Computer Systems
Unit code: H/601/3255
QCF Level 2: BTEC First
Credit value: 10
Guided learning hours: 60

Aim and purpose
The aim of this unit is to introduce learners to the basic hardware and software components that make up
computer systems and for learners to carry out basic installation and configuration.

Unit introduction
Most learners will set up a computer system at some stage, which may belong to them or someone else
and it may be a desktop, laptop, PDA or games console. To do this, learners need to know about the
different elements of a computer system and how hardware works with software and how all the elements
communicate to make the system function.

There are many different manufacturers of computer systems and each manufacturer will produce a
wide range of models with different specifications. Being able to understand a computer systems technical
specification (what all the jargon means) is important. Learners will spend some time in understanding the
function of hardware and software components and assessing potential risks to systems.


Learning outcomes
On completion of this unit a learner should:
1 Know the common components of computer systems
2 Know the different uses of computer systems
3 Be able to connect computer hardware
4 Be able to configure computer software.
