(a) 8 bit microprocessor
(b) 16 bit microprocessor
(c) 4 bit microprocessor
(d) 32 bit microprocessor
(e) 64 bit microprocessor.

Differences between computer organisation and Computer Architecture:

Computer Organisation	Computer Architecture
Often called micro architecture (low level)	Computer architecture (a bit higher level)
Transparent from programmer (ex. a programmer does not worry much how addition is implemented in hardware)	Programmer view (i.e. Programmer has to be aware of which instruction set used)
Physical components (Circuit design, Adders, Signals, Peripherals)	Logic (Instruction set, Addressing modes,Data types, Cache optimization)
