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.
