For D1, I used vendorlib.leighacademy.org.uk to takescreenshots of installing hardware components into thecomputer and installing the Windows XP operatingsystem.Although this was done virtually, during an actualinstallation process, the computer case should beplaced on an anti-static mat, and an anti-static wriststrap should be worn, as this will equalize the charge.This will prevent any of the components from becomingdamaged from Electrostatic Discharge (ESD), and itwill also prevent you from become injured.
This screenshotshows theinstallation of thepower supply.When choosing the appropriate power supply for your computer, you should considerthe amount of wattage needed to power components, such as the CPU and the graphicscard, and the amount of wattage that the power supply actually supplies. You shouldalso consider the actual size as well.
Installing RAM 1Installing RAM 2RAM is the ‘Random Access Memory’, which istemporary storage. Installing two RAMs increasesthe amount of temporary storage available.Before the installation process, the RAM should bestored in an anti-static bag, to avoid them frombecoming damaged by ESD.When installing them, they should be placed incarefully, but with some force to ensure that theyare fitted properly. The latches located either sideof the RAM slot should be closed to ensure that theRAM is secured.
Fitting the CPU Securing the CPUCPU fully installedThe CPU stands for ‘Central Processing Unit’ andis known as the component that carries out themajority of the calculations and processing thattakes place within the computer, meaning that it isone of the most important components.Again, before the installation process, the CPUshould also come in an anti-static bag, to avoid itfrom becoming damaged whilst being delivered orduring traveling.The processor should be placed in the spaceprovided, and the lid should be closed. To secure it,the latch should be lowed. This will keep the CPUsecured and in place.
After the CPU has been securelyinstalled, thermal compound has tobe added onto it to allow the heat tobe conducted more easily.The heat sink is then placed onto the CPU andthermal compound. Heat is distributed in theair around the components, which cools downthe system.
Once the main components have been installed in the Motherboard, the Motherboarditself has to be installed. As you can see, it has to be installed just below the powersupply and it is secured using screws.
This screenshot shows theinstallation of the NetworkInterface Card (NIC). It is securedusing screws. The NIC cardenables the computer to beconnected to an availablenetwork.This screenshot shows theinstallation of the Wireless NIC.Again, it is secured using screws. Itdoes the same job as theNIC, however instead of using acable, it uses radio frequencies.
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 animportant role within the functioning of a computer.
Hard Disk DriveOptical DriveFloppy DriveThe final step is to install the threedrives, which are the Hard Disk Drive(HDD), Optical Drive and Floppy Drive.The HDD is where data is savedpermanently.The Optical Drive reads CDs and DVDs.The Floppy Drive is usually found in oldercomputers and it is where floppy drives areinserted in order to save data.
