  4. 4. Monitor A monitor is the visual component of your computer; it is how you interact with your computer by seeing a visual representation of what you are doing. 4
  5. 5. Tower The tower is where all the processing goes on in a computer; it is the brains of the computer. The tower is connected via a cord to the monitor so you can see what the tower is doing on the monitor. 5
  6. 6. Keyboard The keyboard is also connected to the tower and it is used primarily to enter information into the computer. This information entering is done by typing. 6
  7. 7. Mouse The mouse is the primary tool used to navigate the user interface that is displayed on the monitor. 7
  8. 8. VGA VGA stands for Video Graphics Array. A VGA connector is very important, as it is used to connect the computer tower to the monitor. The VGA connector allows the monitor to display a graphical representation of what is going on in the computer. 8
  9. 9. VGA cont. This is a standard VGA cable. One side plugs in to the monitor, the other side will connect to the computer tower. 9
  10. 10. Ethernet An ethernet cable is used to physically connect the computer to the internet. The internet is worldwide and it is a system of interconnected computer networks. Using these networks, people are able to share information worldwide, and an ethernet cable allows you to connect your computer into this worldwide network. 10
  11. 11. Wireless Another option to connect to the internet is through a wireless card. Many newer computers have a built in wireless card, meaning they can detect nearby routers and you can connect to these routers if you have the proper permissions/ passwords to join them. A router is a device that can send out a wireless internet computer to many computers, allowing them to access the internet. 11
  12. 12. USB USB (Universal Serial Bus) is universal connector to enable many different devices to connect to your computer. In the past, there were different connectors for almost everything to connect to your computer (mouse, keyboard, printer, etc.), and many of these are being replaced with USB connectors. 12
  13. 13. USB cont. This is a standard USB cable. The end that connects to your computer tower will always be the same size. The size of the connector on the other side may differ depending on the device you are connecting to. 13
  14. 14. Laptops Laptops are very similar to tower computers except the monitor, processing components, mouse, and keyboard are all one unit on a laptop instead of being separate. 14

  17. 17. How to Power On You turn on the computer by pushing the power button, which is usually located on the front of the tower. You briefly push the button and then let go – you don’t want to hold down on the power button. The computer will then take a few minutes to power up and be ready to use. 17
  18. 18. How to Move a Mouse There is a pointer icon on the screen that you move by physically moving the mouse. By clicking the buttons on the mouse, you can interact with various programs on the computer. You will physically move the mouse whatever direction you want the pointer to move on the screen – move it up to move the mouse up, left to move it left, etc. 18
  19. 19. Logging On When you first turn the computer on, you will usually see a log on screen after the computer has finished powering on. There will be a menu showing an icon and name for each user that has an account on the computer. Some of these accounts may be password protected and so you will need to know the proper password to access these accounts. You will select the correct name for your account, enter the password if one is required, and then you will be logged in to the computer. 19
  20. 20. Introduction to Keyboards Keyboards are the main tool available to enter text into the computer. If you wanted to type a letter, you would open a word processing program, such as wordpad, notepad, or Microsoft Word. Using wordpad, you can type your letter just as you would write it on paper. However, instead of using pen and paper, you will press on the letters on the keyboard that correspond to the letters you wish to type. 20
  21. 21. Basics Computer Functions How to open a program. Functions of left and right clicks Ctrl+C, Ctrl+Alt+Delete, and other key combinations Basic programs 21
  22. 22. How to Open a Program To open a program you will usually double click on the program name if you are selecting it from the desktop by using the left mouse button to click. If you are selecting the program from the start menu you will usually only need to click on the program name once, again using the left mouse button. 22
  23. 23. Left and Right Clicks When using a mouse, there are typically two buttons – a left button and a right button. The left mouse button is usually used to open up programs and folders. The left mouse button is also used when interacting with the various tools inside an open program. The right mouse button is used more to view information about things such as files and folders. 23
  24. 24. Important Keystrokes CTRL+C (Copy) CTRL+X (Cut) CTRL+V (Paste) CTRL+Z (Undo) CTRL+ALT+DELETE (if computer freezes this will give you access to end the program) 24
  25. 25. Basic Programs Some examples of basic programs that come preinstalled on computers are word processing programs and picture editing programs. Notepad is a basic text editing program where you can input text and then save it as a file. Paint is a basic picture editing program where you can use some simple tools to draw new pictures or edit preexisting pictures. 25
