1. Connecting basic peripherals

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  devices, 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  output device 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 BIOS Install  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  Microsoft ’s Windows . Other  examples  of operating systems are: Apple ’s  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  Microsoft ’s 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 the BIOS  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 user’s 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 boot device . 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 logical drives .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 computer reboots ,  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 the Enter   key. Read the Windows XP  License  Agreement, then press  F8  to agree with the terms and conditions and proceed with the installation.

14. Deleting a partition To delete a partition. Select the drive thenpress  D , and then press  Enter , and finally press the  L  key.

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  stored on 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 and Language Options . Procedure : When Windows XP starts for the first time it will scan for any  new hardware  and will install  the needed  drivers  of the supported devices, this may take several minutes to complete.  

19. 2. The Regional and Language Options screen will appear. Click the  Next  button to accept the default setting and continue.

20. On the  Personalize Your  Software  screen, enter your name and organization. Then click the  Next  button to continue.

21. Next, enter your  Windows XP  Product Key that comes with your Installation CD. The product key  is 25 characters long and is unique for every installation CD. Once you have entered the product key, click the   Next button to continue.

22. Step 5: Setting up the computer name and administrator account   The  Computer name  is used to identify your computer in a network. This name should be unique for each computer. The  Administrator  is a super user account that has no restrictions. This account may be used to set configuration options (e.g. network settings, install software and perform other administrative tasks). Procedure: On the  Computer Name   and Administrator 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  Next button 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   Next button to continue.

25. Setting up the display    Procedure: After the computer  reboots  and loads into Windows , a display setting dialog box will appear. Click  Ok  to let Windows XP adjust your  screen resolution . Windows will automatically detect the best resolution for your  monitor ; this will make sure that the text will be readable.

26. On the  Welcome to  Microsoft   Windows screen , click  Next  to continue

27. ep  9: Registering  Windows  XP   By  registering  your copy of Windows you will have access to Windows updates and security patches. This will be downloaded to and installed on your computer automatically. Procedure: Windows will now check for your  internet connectivity , click the  Skip  button to continue. At this time, we will not be registering Windows, so on the registration screen, click on the  "No, not at this time option"  and click on the  Skip  button to continue.

28. Step 10: Creating log-in credentials   Creating log-in credentials is useful when the computer is to be used by multiple users. Windows will create document folders that are only accessible to specific user. For this task, you will be creating one (1) user credential. Procedure: On the "Who will use this computer?" screen, enter your desired user name and click on the  Next  button. This credential will be used every time you log-in to your computer.

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
