1. What is a Computer?

A computer is a powerful electronic device that can accept data (input), process it according to specific instructions (software), store the information, and produce the desired results (output). It operates on logical operations and can perform millions of tasks in a second.

      Computers are essential in modern life — from education, business, and healthcare to entertainment, research, communication, and artificial intelligence.
    

📌 Key Functions of a Computer:

Input: Receiving data from devices like keyboards, mice, or scanners.
Processing: The CPU processes instructions and makes decisions.
Storage: Saving data temporarily (RAM) or permanently (HDD/SSD).
Output: Displaying results through monitors, printers, or speakers.
