Computer Organization[1]
A computer is an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.[2]

Big ideas in computer organization[edit]

This lecture (quite long) is an excellent introduction to the deeper ideas presented on this page. I strongly advise you to watch this.


Computer architecture[edit]

Secondary memory[edit]

Operating systems and application systems[edit]

Binary Representation[edit]

Simple logic gates[edit]

Standards[edit]

  • Outline the architecture of the central processing unit (CPU) and the functions of the arithmetic logic unit (ALU) and the control unit (CU) and the registers within the CPU.
  • Describe primary memory.
  • Explain the use of cache memory.
  • Explain the machine instruction cycle.
  • Identify the need for persistent storage.
  • Describe the main functions of an operating system.
  • Outline the use of a range of application software.
  • Identify common features of applications.
  • Define the terms: bit, byte, binary, denary/decimal, hexadecimal.
  • Outline the way in which data is represented in the computer.
  • Define the Boolean operators: AND, OR, NOT, NAND, NOR and XOR.
  • Construct truth tables using the above operators.
  • Construct a logic diagram using AND, OR, NOT, NAND, NOR and XOR gates.
