HTML Introduction

A computer is an electronic device that processes data according to a set of instructions called a program. It takes input, processes it, stores it, and produces output.

Key Functions of a Computer:

1. Input – Receiving data (e.g., from a keyboard, mouse, or sensor).

2. Processing – Performing calculations or logical operations (done by the CPU).

3. Storage – Saving data for immediate or future use (using RAM or hard drives).

4. Output – Displaying or transmitting the result (e.g., to a monitor or printer).

5. Control – Directing the manner and sequence of all operations.

Main Components:

• Hardware: The physical parts (e.g., CPU, memory, motherboard, keyboard).

• Software: Programs and operating systems that tell the hardware what to do.

Types of Computers:

• Personal Computers (PCs) – For general use at home or office.

• Laptops – Portable computers with built-in display and keyboard.

• Servers – Powerful machines that provide data/services to other computers.

• Supercomputers – Extremely fast computers used for complex calculations.

• Embedded Systems – Computers built into other devices (e.g., washing machines, cars).

In Simple Terms:

A computer is like a very fast and obedient assistant that follows exact instructions to solve problems, store information, and perform a wide range of tasks automatically.
