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.
