1. Computer architecture vs organization

Key Concepts & Definitions

  • Computer Architecture: Computer architecture deals with the operational attributes of a computer.
  • Computer Organization: Computer organization mainly focuses on implementing the architecture.
  • Instruction Set Architecture ISA: Instruction Set Architecture is the part of architecture that specifies the instruction set.

Essential Points

  • Computer architecture is tested as operational attributes rather than physical wiring.
  • Computer organization is tested as implementation rather than internet speed or graphics design.
  • ISA is identified as belonging to computer architecture in the MCQ.
  • Hardware details are identified as belonging to computer organization in the MCQ.

Memory Hook

Architecture = what it does; Organization = how it’s built.
