Study Notes
Computer Introduction
- A computer is an electronic device controlled by instructions stored in memory.
- Computers perform four basic tasks: input, processing, output, and storage.
- Input: Accepting data through input devices.
- Processing: Transforming data into useful information using processing devices.
- Output: Displaying or producing information on output devices.
- Storage: Saving information for future use in storage devices.
Computer System
- A computer system is a complete and functional computer with hardware and software.
- Hardware: The physical components of the computer system.
- Software: The instructions that tell the computer what to do.
- Data: Raw facts and figures that are processed.
- Information: Processed data that is meaningful.
- User: A person who interacts with the computer to perform specific tasks.
Data/Information
- Data is raw, unprocessed facts.
- Data is transformed by the computer to become information.
Hardware
- Hardware is the physical components of a computer system.
- Four categories of basic hardware: input, processing, storage, and output.
- Input devices: Capture and enter input data, validate data.
- Processing devices: Perform computations, make decisions.
- Storage devices: Store, access, and update data.
- Output devices: Produce or display information.
- Common hardware examples: Microprocessor, RAM, expansion cards, power supply, scanner, keyboard, monitor, mouse, hard disk, optical disc drive, motherboard, speakers, printer, external hard disk.
Software
- Software is a set of instructions directing computer functions.
- Users interact with the computer through software.
- Two categories of software: system software & application software.
- System software directly interacts with the computer hardware—managing the computer's resources and processes.
- Application software is designed to perform specific tasks.
- Examples of system software: operating systems (like Windows, macOS, Linux).
