An Overview of Computer Organization
Chapter 1
Some Definitions
or the Type of
Structure & Function
• Structure is the way in which components relate to each other
• Function is the operation of individual components as part of the structure
Function
• All computer functions are:– Data processing– Data storage– Data movement– Control
Functional view
• Functional view of a computer
