2. For D1, I used vendorlib.leighacademy.org.uk to take
screenshots of installing hardware components into the
computer and installing the Windows XP operating
system.
Although this was done virtually, during an actual
installation process, the computer case should be
placed on an anti-static mat, and an anti-static wrist
strap should be worn, as this will equalize the charge.
This will prevent any of the components from becoming
damaged from Electrostatic Discharge (ESD), and it
will also prevent you from become injured.

3. This screenshot
shows the
installation of the
power supply.
When choosing the appropriate power supply for your computer, you should consider
the amount of wattage needed to power components, such as the CPU and the graphics
card, and the amount of wattage that the power supply actually supplies. You should
also consider the actual size as well.

4. Installing RAM 1
Installing RAM 2
RAM is the ‘Random Access Memory’, which is
temporary storage. Installing two RAMs increases
the amount of temporary storage available.
Before the installation process, the RAM should be
stored in an anti-static bag, to avoid them from
becoming damaged by ESD.
When installing them, they should be placed in
carefully, but with some force to ensure that they
are fitted properly. The latches located either side
of the RAM slot should be closed to ensure that the
RAM is secured.

5. Fitting the CPU Securing the CPU
CPU fully installed
The CPU stands for ‘Central Processing Unit’ and
is known as the component that carries out the
majority of the calculations and processing that
takes place within the computer, meaning that it is
one of the most important components.
Again, before the installation process, the CPU
should also come in an anti-static bag, to avoid it
from becoming damaged whilst being delivered or
during traveling.
The processor should be placed in the space
provided, and the lid should be closed. To secure it,
the latch should be lowed. This will keep the CPU
secured and in place.

6. After the CPU has been securely
installed, thermal compound has to
be added onto it to allow the heat to
be conducted more easily.
The heat sink is then placed onto the CPU and
thermal compound. Heat is distributed in the
air around the components, which cools down
the system.

7. Once the main components have been installed in the Motherboard, the Motherboard
itself has to be installed. As you can see, it has to be installed just below the power
supply and it is secured using screws.

8. This screenshot shows the
installation of the Network
Interface Card (NIC). It is secured
using screws. The NIC card
enables the computer to be
connected to an available
network.
This screenshot shows the
installation of the Wireless NIC.
Again, it is secured using screws. It
does the same job as the
NIC, however instead of using a
cable, it uses radio frequencies.

9. The next adapter card to install is the Video Adapter Card. It is secured using screws.
Monitors can display content because of the Video Adapter Card, so it plays quite an
important role within the functioning of a computer.

10. Hard Disk Drive
Optical Drive
Floppy Drive
The final step is to install the three
drives, which are the Hard Disk Drive
(HDD), Optical Drive and Floppy Drive.
The HDD is where data is saved
permanently.
The Optical Drive reads CDs and DVDs.
The Floppy Drive is usually found in older
computers and it is where floppy drives are
inserted in order to save data.
