Question

Differentiate Computer Organisation from Computer Architecture.

Answer 1

Computer Organisation:

• Often called microarchitecture (low level).
• Transparent from the programmer (example: a programmer does not worry much about how addition is implemented in hardware).
• Physical components (Circuit design. Adders, Signals, Peripherals).

Computer Architecture:

• Computer architecture (a bit higher level)
• Programmer view i.e. The programmer has to be aware of which instruction set used)
• Logic (Instruction set, Addressing modes, Data types, Cache optimization)
