Definition:

A computer is an electronic device that processes data to perform various tasks. It takes input, processes it, stores information, and produces output.


Basic Functions of a Computer:

  • Input – Accepts data through devices like keyboard, mouse, etc.
  • Processing – Uses the CPU (Central Processing Unit) to process the input data.
  • Storage – Saves data temporarily (RAM) or permanently (HDD/SSD).
  • Output – Displays the processed data via monitor, printer, etc.

Types of Computers:

  • Supercomputer – High-speed and powerful, used for scientific research.
  • Mainframe Computer – Used in large organizations for bulk data processing.
  • Personal Computer (PC) – Used by individuals for general tasks.
  • Embedded Systems – Computers integrated into devices like washing machines, ATMs, etc.

Components of a Computer:

  • Hardware – The physical parts (CPU, RAM, Hard Disk, Monitor, etc.).
  • Software – Programs that run on a computer (Operating System, Applications).

Characteristics of a Computer:

  • Speed – Computers process data at extremely high speeds compared to humans.
  • Accuracy – Performs calculations and operations with high precision.
  • Automation – Once a program is executed, the computer works automatically.
  • Versatility – Can perform different types of tasks (gaming, calculations, designing, etc.).
  • Storage – Can store vast amounts of data permanently or temporarily.
  • Connectivity – Can connect to the internet and other devices for communication.
  • Multitasking – Can perform multiple tasks at the same time efficiently.
