Introduction to Computers—Everything You Need to Know

Imagine a machine that can do your homework, show you your favourite videos, and help you learn new things with just a few clicks. That amazing machine is called a computer.

This term is derived from the Latin word computare, which means to calculate and count. It was used in mathematical computations. At present, it represents devices that can perform a huge number of jobs, like calculations and complicated problem-solving.

Charles Babbage invented the first computer machine in the 1800s, which was called an analytical engine. It is specially used for mathematical purposes. His invention helped develop the modern computer.

Join the fun! Let’s explore the awesome world of computers.

What is computer?

A computer is a machine that performs various tasks using information. It can save data, process commands, and show results.
