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.

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.

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)

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.

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.

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.

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.
