Architecture(those attributes visible to the programmer)
Organization (the operational units and their interconnections that realize the architecture)
This hierarchical organization is described in this book from the top down: Computer system, Processor, Control unit
The examples of this book are drawn from two computer families: the Intel Pentium II, and the PowerPC.

Part Three —The central processing unit
The CPU consists of a control unit, registers, the arithmetic and logic unit, the instruction execution unit, and the interconnections among these components.
Part Four — The control unit
The control unit is that part of the processor that activates the various components of the processor. This part looks at the functioning of the control unit and its implementation using microprogramming.

Architecture & Organization 1
Computer architecture is those attributes visible to the programmer, or, those attributes that have a direct impact on the logical execution of a program.
Architectural attributes: instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques.
