In this presentation it explains why hardware is installed and the problems that can happen, It also explains how it can be prevented. This presentation is part of my IT coursework*

2. Benefits of Installing expansion
• Expansion
on a computer system are the graphics card, PCI
cards, Wi-Fi card, video cards and sound cards.
• These can
be installed as an upgrade to make the computer
system faster and updated.
• Nowadays these
are mostly inputted and already installed onto
the motherboard. An example that is commonly upgraded is the
graphics card.
• Another
reasons it might be installed is too replace faults in the
computer system and repair the machine.

3. Potential problems
• Before
dealing with a computer system in the workshop, training
must be done for installing, disposing and dealing with computer
components safely.
• It’s
important for an technician to understand and know the risks
that can occur, so it can be prevented and dealt with.
• There are
many problems that could happen when installing
hardware. This can be caused by a small accident.

4. Effects
• This
can effect data, damage to computer components and
electrostatic charge.
• Electrostatic
charge: This is the electricity between the technician
and the computer component.
• Damage to
damaged.
• Data:
computer components: This is when the component is
information that is stored onto the computer. (HDD)

5. Electrostatic charge
• The electricity
in the circuit on the components are harmless to
users/technicians, but they are very sensitive and could be
damaged.
• This can
cause damage to the component when they build up
static electricity which is released on the technician and becomes
discharged.

6. Component damage
• When
handling with any component and computer, they is as
chance that it may get damaged, as there is many ways.
• The
common ways a component can get damaged is by dropping
the component, turning screws too much ruining the
treads, bending a pin or socket, and by loosening a cable in a plug.

7. Data
• The two
main risk that may occur is data corruption and data loss.
• Data
corruption is when data is damaged by errors. This means the
data is still recognised by the system but cannot be viewed or
usable. The cause of this may be from not copying the file
completely or correctly.
• Data
loss happens when the HDD is damaged or formatted. If
data is lost, it cannot be retrieved without a backup.

8. Precautions to avoid problems
• Electrostatic charge: A
antistatic wristband must be worn, which is
attached to a metal part inside the tower and an antistatic mat
should be used, which is placed underneath the computer.
• Damage to
computer components: Use tools and equipment
correctly, to be careful, concentrate all times and to take time
when handling.
• Data:
It is important to backup all data from the computer, as
anything could happen.
