Computers have become an integral part of our lives, transforming the way we work, communicate, learn, and even entertain ourselves. Understanding computers is essential in today's digital age, and this comprehensive guide will provide you with a thorough understanding of these remarkable devices.
What is a Computer?
A computer is a programmable electronic device that can store, process, and retrieve data. It consists of hardware (physical components) and software (instructions that tell the hardware what to do).
Common hardware components include:
How Computers Work
Computers work on a binary system, using only two digits (0 and 1) to represent data. These binary digits, called bits, are grouped into bytes (8 bits each). Computers execute instructions step-by-step, processing data and storing the results in memory or storage.
