1. William Stallings Computer Organization and Architecture 7th Edition
Chapter 1 Introduction

2. Architecture & Organization 1
Architecture (結構) is those attributes visible to the programmer
Instruction set, number of bits used for data representation, I/O mechanisms, addressing techniques.
e.g. Is there a multiply instruction?
Organization is how features are implemented
The operational units and their interconnections that realize the architectural specifications (規格).
Control signals, interfaces, memory technology.
e.g. Is there a hardware multiply unit or is it done by repeated addition?

3. Architecture & Organization 2
All Intel x86 family share the same basic architecture
The IBM System/370 family share the same basic architecture but with differences in organization.
This gives code compatibility (相容性)
At least backwards
Organization differs between different versions

4. Structure & Function
A computer is a complex system, containing millions of elementary electronic components.
A hierarchical (階層式) system
At each level in the hierarchy, structure and function are concerned.
Structure is the way in which components (元件) relate to each other.
Function is the operation of individual components as part of the structure.

5. All computer functions are:
Data processing
Data storage
Data movement
Control

6. Functional view
Apparatus: 裝置   

7. Operations (1) Data movement

8. Operations (2) Storage

9. Operation (3) Processing from/to storage

10. Operation (4) Processing from storage to I/O
