  • 1. CPD 2113 TECHNOLOGY IN ELT Chapter 2 COMPONENTS OF COMPUTER SYSTEM MURNI SALINA B.Sc. Ed (TESL) UTM, Skudai M’sia
  • 2. COMPONENTS OF A COMPUTER SYSTEM  A computer system has three main components : ◦ Hardware ◦ Software ◦ Warmware  A computer system performs 4 important tasks (Sharp, 2005:35) ◦ ◦ ◦ ◦ Receiving input : figures, facts or sets of instructions Storing information : place in memories Processing the data : act on the information Outputing the information : process and generate results
  • 3. 4 MAIN ASPECTS OF DATA HANDLING 1. 2. 3. 4. Input devices - accept data or commands in a form that the computer can use: they send the data or commands to the processing unit. The Processor - known as CPU, has electronic circuitry that manipulates input data into information that people require. The CPU execute computer instructions. Output Devices - display the people the processed data; information in understandable and usable form Storage - means secondary storage; consists of secondary storage devices such as hard disk, diskettes, pendrives. - can store data and programmes outside the computer itself. - these devices supplement memory or primary storage, can hold data or programmes temporarily.
  • 4. 1. What is Input? Input refers to any data or instructions that are used by a computer. All computer processing requires data. Whenever you use computer or application software, you are providing input. You typically use a keyboard to type text and a mouse to issue commands.
  • 5. Input Devices            Keyboard Mouse Joystick Touch Screen Light Pen Scanner Bar code readers Digital cameras Video cameras Graphic tablets Voice recognition systems
  • 6. 2. What is Process? The computer manipulates the data to create information. Information refers to data processed into a form that has meaning and is useful.
  • 7. Processing Devices/System Units Mother board/System  CPU/Microprocessor  Memory – RAM, ROM  Expansion Slots and Cards  System Clock  Bus Lines  Ports and Cables 
  • 8. 3. What is Output? Is a processed data or information. Output devices provide output to people by translating what the computer has processed into a form that people can understand and use.
  • 9. Output Devices Monitor – CRT, LCD  LCD projector  Video scan converter  Printer 
  • 10. 4. What is Storage? Information can be stored in a computer for future use. All computers have a hard disk drive to store programmes and data.
  • 11. Storage Devices Hard Disk  Removable Disks  ◦ ◦ ◦ ◦ ◦ Floppy Drive CD-ROM, R, RW DVD-ROM, R, RW Pen Drive, Thumb Drive, Zip Drive External Hard Disk
  • 12. TEST YOUR UNDERSTANDING!
  • 13. Visualize these components and draw them!        Keyboard Mouse Monitor Speaker Webcam Printer CPU         Mother board Slot Card RAM USB port PS2 port Parallel port Serial port Floppy Drive
