Study Notes
- Computer systems carry out operations using several basic components working together
Input Unit
- It is used to transfer raw data and control signals into the information processing system
- This occurs before processing and computation
- Input units have several functions
- Accepting data and sets of instructions/commands
- Converting data into a form that the computer can accept
- Providing the converted data for further processing
Central Processing Unit
- This serves as the "brain" of the computer system
- It consists of three main parts
- Control Unit: controls, manages, and coordinates operations of the entire computer system
- Arithmetic Logic Unit: executes instructions and performs calculations/decisions
- Primary Storage Unit: Also known as "main memory," temporarily stores data to be outputted
Output Unit
- It gives the results of processing and computations to the outside world
- Output units accept results produced by the computer
- Output units convert results into a human-readable form
- Output units supply the results to the users
Components of Computer System
- Computer hardware consists of the internal and peripheral devices, they are the physical parts of the computer
- Input, output, central processing, and storage devices are all hardware examples
Computer Software
- Also known as programs or applications, providing the computer with "intelligence"
- Computer software is classified into two classes
- System software
- Application software
