- 2. Identify the basic peripherals needed to start up a computer system Connect the basic peripherals to a computer system unit Start up the computer system
- 3. This is the system unit. It is the main part of the computer system and houses the Central Processing Unit (CPU), motherboard,memory, storage de vices, expansion cards and the power supply.
- 4. Computer peripherals are devices that are attached to a computer. These devices are not part of the system unit, but are important since they provide the input and output functions in order for the users to perform their tasks. The basic peripherals that you will need to start- up the computer are: Monitor Keyboard Mouse
- 5. Monitor A computer monitor or display screen is an outputdevice that enables the user to view text, graphics and videos
- 6. keyboard is an input device that allows the user to enter instructions and information into a computer.
- 7. A mouse is an input device that controls the movement of the cursor or pointer and enables the user to move and select items that are displayed on the monitor.
- 8. Installing an operating system t the end of this session, you will be able to: Configure boot options in the BIOSInstall an operating system on a computer
- 9. An operating system or OS is a program that is loaded after the computer starts-up and manages all operations and applications in a computer. The most popular operating system is Microsofts Windows. Other examples of operating systems are: Apples Mac OS X Redhat Linux, and other open source distributions of Linux Why do we need to install an Operating System? Without an operating system a computer is just a metal casing with components inside it. The operating system acts as an interface between the user and the computer, translating the user inputs into machine instructions and, thus letting the computer perform the desired task.
- 10. Installing Windows XP In this session you are going to install Microsofts Windows XP. What you will need: Computer system with at least 1GB memory and a 500GB hard disk drive Windows XP installation CD Windows XP license key System manual that comes with your computer
- 11. Step 1: Setting up the boot option Why do we need to set the computer to boot from the CD-ROM drive? Normally a computer system boots from the hard drive. From here, the computer loads the operating system that is installed on the computer system. Since we are installing a new operating system on the computer, and our installation files are stored in a CD-ROM, we need to set the computer to boot from the CD-ROM drive instead. This is done in theBIOS setup. Procedure: Turn on the computer.Press the Delete key while the computer is starting up to enter the BIOS setup. This will work on most computer systems. Note: Other computers have function keys to access the BIOS setup. You may need to consult your users manual on how to access the BIOS setup screen. In the BIOS setup screen, look for the Boot Options Menu. This is usually found at the top of the screen. In some computers it is found in the Advance menu. Select the CD-ROM Drive as the first bootdevice. Go to the Exit menu and select Save and Exit to save your configuration. Note: You may need to consult the User's Manual on how to set the CD-ROM Drive as first boot device.
- 12. Step 2: Partitioning the hard drive What is disk partitioning? Disk partitioning is simply dividing your hard drive into multiple volumes known as logicaldrives.As an example, if you have a 500 GB hard drive, you can divide the hard drive into two volumes, each with 250GB (e.g. 250 GB drive C: and 250 GB drive D:). By doing this, you can install the operating system and applications in one volume and your data and documents in another volume. In case the operating system gets corrupted and needs to be re-installed, you can do so without losing documents and other data since these are stored in another partition.
- 13. Procedure: Insert the Windows XP Installation CD in the CD-ROM drive and restart the computer. When prompted as the computerreboots, press any key to start the installation. After the installer completes copying all necessary files to install Windows XP, you will be taken to the welcome setup screen. To install a fresh copy of Windows XP, press theEnter key. Read the Windows XP License Agreement, then press F8 to agree with the terms and conditions and proceed with the installation.

- 15. Creating a partition When the partition with a previously installed operating system has been deleted,a new partition can now be created on the hard disk. Press C key on the keyboard to create a new partition. In this example you will use 60 GB as the partition size . Enter 60000 MB as the partition size and press ENTER. After creating the partition, you will be brought back to the hard disk partition screen. Select the partition that you have created then press ENTE
- 16. Step 3: Formatting the hard drive Why do we need to format the hard drive? Formatting the hard drive is a process that prepares the hard drive for writing and reading data. The process involves erasing all data storedon the hard drive. It also tests the disk for errors and corrects them if any are found. When formatting the hard drive, we need to specify a file system. In Windows XP, we can select either the FAT32 or NTFS.
- 17. Procedure: Select Format the partition using the NTFS file system option and press ENTER to continue. After the drive is formatted, the installer will copy the installation files to your hard disk. Once all the operations are completed, the computer will restart. Note: Do not remove the Windows XP installation CD from the CD-ROM Drive while the computer is restarting. After the computer reboots, it willautomatically start the Windows installer.You may proceed to the next step.
- 18. Step 4: Setting up the Windows environment Setting the Windows environment lets you localize the version of Windows you are installing. For example, if you want to display text in Chinese, you can set this in the Regional andLanguage Options.Procedure: When Windows XP starts for the first time it will scan for any new hardware and willinstall the needed drivers of the supported devices, this may take several minutes to complete.

Procedure: On the Computer Name andAdministrator Password screen, enter your desired computer name and password. Click on the Next button to continue.
- 23. Step 6: Setting up the date and time Set the correct date and time. This is important especially when downloading updates and security patches. Procedure: On the Date and Time settings, enter the correct date and time. Select your time zone then click on the Nextbutton to continue.
- 24. Setting up the network Setting up the network connects your computer to the internet and/or to your local area network. By doing this, you will be able to access shared network resources such as files, applications and devices.Procedure: Windows XP will now detect network connections. If the network card in the computer is supported by Windows XP. It will install the drivers for you. Once finished, select Typical Setting and click the Nextbutton to continue.

- 29. A. An Operating system is important for a computer system as it acts as an interface between the user and the computer. Without it a computer will not be able to perform tasks. B. There are ten (10) essential steps you need to remember when installing a Windows Operating System, these are: Setting up the boot optionPartitioning the hard driveFormatting the hard driveSetting up the Windows environmentSetting up the computer name and administrator accountSetting up the date and timeSetting up the networkSetting up the displayRegistering Windows XPCreating log-in credentials
