Computer Basics Quiz

A computer is an electronic device that processes data, performing various tasks according to a set of instructions called programs.

Hardware: Physical components of a computer
- CPU (Central Processing Unit): The brain of the computer; performs calculations and tasks.
- RAM (Random Access Memory): Temporary storage that allows for quick data access.
- Storage:
  - HDD (Hard Disk Drive): Traditional storage device with moving parts.
  - SSD (Solid State Drive): Faster, more reliable storage with no moving parts.
- Motherboard: Main circuit board connecting all components.
- Power Supply Unit: Converts electrical power to usable form for the computer.
- Input Devices: Examples include keyboard and mouse.
- Output Devices: Examples include monitor and printer.
Software: Programs that run on the computer
