  1. Chapter 1Types and components of Computer Systems:Computer Components

  2. WALT • To know a description of a computer system. WILF • All students will be to provide examples of the main components of a computer system(Grade E/D). • Most will know the descriptions of the components roles and uses (Grade D/C). • Some students will be able provide examples of different types of storage devices (Grade B/A).

  3. Introduction • In this lesson we will look at the different components (parts) of a computer system. You will see what role each component plays within the computer system. • You will also get to understand the features of each component. • This lesson also briefly introduces the different forms of storage devices that we use to hold data.

  4. Computer Components DEFINITION: "All the different pieces of electrical hardware that join together to make up the complete computer system.”

  25. Output Devices When inputted raw data has been processed it becomes usable information. Output devices are pieces of hardware that send this usable information out of the computer. Some output devices send information out temporarily and some send information out permanently: Temporary Output Devices - E.g. Monitors which constantly refresh the outputted image on the screen Permanent Output Devices - E.g. Printers which output information onto paper as a hard copy.
