Topic 1 Introduction to Computer Architecture
Main component
Central processing unit(CPU)
To control the operation of the computer and performs it data processing functions
Main Memory
To store data
Input/Output
To move data between the computer and its external environment
System Interconnection
To provide communication among CPU, main memory and I/O
Ex:system bus
Major component in CPU
Control Unit
Control the operation of the CPU and the computer
Register
To provide storage internal to the CPU
Arithmetic and logic unit (ALU)
To perform the computer's data processing functions
CPU interconnection
Provides for communication among the control unit, ALU and register
Computer Generations
First Generation (1944-1958) - Vacuum Tube
Only solve one problem at one time
generated a lot of heat and easily burnt
Second Generation (1959-1964) - Transistors
smaller, draw less power and less heat
moved from language to assembly languages
Third Generation (1964-1970) - Integrated Circuit (IC)
Faster and more efficient
Using output device to interact with operating system
Fourth Generation (1971- present) - Mircoprosessors
single and tiny silicon chips with millions of transistors
Development of GUIs
Fifth Generation (present and beyond) -Artificial Intelligence (AI)
Making computer behave and think like humans
