Study Notes
Computer Basics
Software
- System Software: manages computer hardware and provides a platform for running applications (e.g. operating systems, device drivers)
- Application Software: performs specific tasks or functions (e.g. word processors, web browsers, games)
- Programming Languages: used to create software (e.g. Python, Java, C++)
Input Devices
- Keyboard: allows user to input text and commands
- Mouse: allows user to interact with graphical user interface (GUI)
- Scanner: reads physical documents and images into digital format
- Microphone: allows user to input audio
- Webcam: captures video and images
Hardware
- Central Processing Unit (CPU): executes instructions and performs calculations
- Memory (RAM): temporarily stores data and applications
- Motherboard: connects and supports hardware components
