Study Notes

Computer System Architecture

A computer system simplifies complex tasks while maximizing performance and minimizing costs and power consumption.
Key components of Computer System Architecture include:
- Input Unit
- Output Unit
- Storage Unit
- Arithmetic Logic Unit (ALU)
- Control Unit

Data Flow in Computer Systems

Input data travels from the Input Unit to the ALU for processing.
Computed data is sent from the ALU to the Output Unit.
Data frequently moves between the Storage Unit and ALU for computation and storage.
The Control Unit manages operations and data flow among all units.

Input Unit

Links external environment to the computer, providing data inputs.
Converts input from devices into machine language for processing.
Common input devices include keyboards and mice.

Output Unit

Connects the computer with the external environment by providing processed results to users.
Output often takes the form of audio or video.
Common output devices include monitors, printers, speakers, and headphones.

Storage Unit

Contains components for data storage, categorized into:
- Primary Storage: Known as main memory, directly accessible by the CPU.
- Secondary Storage: Not directly accessible by CPU; requires data to be loaded into primary storage for use.
Secondary storage offers large capacity for permanent data retention.

Arithmetic Logic Unit (ALU)

Performs all mathematical calculations within the computer system.
Capable of executing operations such as addition, subtraction, multiplication, and division.
Works closely with the Control Unit, which coordinates data transfer between the Storage Unit and ALU for calculations.

Central Processing Unit (CPU)

Comprised of the ALU and Control Unit, responsible for executing instructions and processing data within the computer system.
