Architecture & Organization 1
Architecture is those attributes visible to theprogrammer
Instruction set, number of bits used for datarepresentation, I/O mechanisms, addressingtechniques.
e.g. Is there a multiply instruction?
Organization is how features are implementedControl signals, interfaces, memory technology.
e.g. Is there a hardware multiply unit or is it done byrepeated addition?

Architecture & Organization 2
All Intel x86 family share the same basicarchitecture
The IBM System/370 family share the samebasic architecture
This gives code compatibility
At least backwards
Organization differs between different versions

Structure & Function
Structure is the way in which components relateto each other
Function is the operation of individualcomponents as part of the structure
