Architecture And Organisation

Architecture

The architecture of a computer is an analysis of the computer done by a software designer. When we think about a computer's architecture, we are concerned about how it behaves.

Organisation

The organisation of a computer is how the computer is implemented in hardware. When we think about a computer's organisation, we are concerned about how its made.

To compare it to biology, one might say that architecture is the physiology of a computer, while organisation is its anatomy.
