UNIT 14: INSTALLING &
MAINTAINING
COMPUTER HARDWARE
FROM THIS UNIT THE LEARNER WILL:
•
A understand the benefits and implications
of installing and maintaining hardware in
technology systems
•
B plan installation and maintenance of
hardware in a technology system
•
C install, maintain and test hardware in a
technology system
•
D review the modified technology system.
Assignments:
•
A1 – Investigation: Prepare a presentation or
a report for the ‘client’. (P1 M1 D1)
•
Assignment 2 – Planning: Your task is to plan
the installation and maintenance of
hardware to fulfil the user requirements for
the ‘client’. (P2, P3, M2, D2)
•
Assignment 3 - Repair and Upgrade: Practical
application, you must demonstrate that you
can follow your plan (P4, P5, M3, M4, D3)
Assignments:
•
Assignment 4 – Review: Prepare a
presentation or a report for the ‘client’ to
evaluate the modified technology system,
explaining why and how it meets the brief
(P6, M5, D4)

Learning Aim A
What hardware can you think of?
1. Compile two lists – one showing components which are
internal e.g. processor the other showing external
hardware e.g. printer There should be at least 6 items
in each list.
2. Give a brief description of each component/device that
you have listed:
•
1.
2.
3.
What does it do?
Who are the major manufacturers?
What does it connect with?/How does it connect? Provide
a picture.
You have 1 hour to complete this task.

REASONS TO MAINTAIN TECHNOLOGY
SYSTEMS
•
Know why we maintain technology systems,
e.g.:
to prevent faults occurring and/or to repair
faults
• Routine Maintainence
• to upgrade internal components, e.g. processor,
memory and/or storage, to improve performance
• to upgrade external hardware devices to improve
performance
• to change system functionality, e.g. to network
the technology system or allow
printing/scanning.

•
This may be because of a change in the system, i.e. a
new software installation

ROUTINE MAINTENANCE
•
WHY DO COMPONENTS FAIL?
•
Heat
•
•
•
•
•
•
•
accelerates aging
causes glitches
Dust build up prevents heat dissipation
Dust can short out components
Unstable power causes crashes and failures
Static electricity can destroy components

WHY DO COMPONENTS FAIL?
What happens if a processor gets too hot?
