  4. The Basic Structure of A Computer System Consists of Three Parts 1. CPU - Central Processing Unit

  5. The Basic Structure of A Computer System Consists of Three Parts 1. CPU Performs arithmetic and logic operations 2. INPUT – OUTPUT DEVICES Keyboard, Monitor, Modem, Mouse, Joystick, Speakers, Printers, etc. 3. MEMORY Primary – directly accessible by the CPU. Secondary – external memory for storing data. (Peripherals)

  6. Computer Hardware The physical components of a computer system, such as the circuit boards, chassis, enclosures, peripherals, cables, etc. It does not include data or computer programs.

  7. Computer Diagram The Block Diagram as shown below is a representation of the fundamental pieces of any computer system. So whether it is a PC or MAC or some other type of computer it will have most if not all of these components.
