Organization indicates its performance.

Organization describes how it does it.

.....................: The way in which the components are interrelated.

.................: The operation of each individual component as part of the structure.

Registers Provides storage internal to the CPU.

............... stores instructions and data.

...................... stores microprogram.

For less values of shift moves, Shift/Add circuits are slower (low speed) than multiplication circuit

Compiler can convert Multiplication operations into Shift/Add operations

Data may take a wide variety of forms, and the range of processing requirements is broad

Within the computer, a control unit manages the computer’s resources and orchestrates the performance of its functional parts in response to instructions

when data are received from or delivered to a device that is directly connected to the computer, theprocess is known as input–output (I/O), and the device is referred to as a peripheral

provides for communication among CPU, main memory, and I/O

Moves data between the computer and its external environment

Controls the operation of the computer and performs its data processing functions; often simply referred to as processor

image conversion is an example of indexing

Controls the operation of the CPU and hence the computer

Performs the computer’s data processing functions
