Who invented the computer?

The second question after what is computer? is who invented the computer?

Charles Babbage is known as the “Grand Father” of the computer.

The First mechanical computer structured by Charles Babbage was called the Analytical Engine. It uses read-just memory in the form of punch cards.

The computer is a progressed electronic device that accepts raw information as a contribution from the user and processes these data under the control of a set of directions (called program) and gives the outcome (output) and saves output for future use.

It can process both numerical and non-numerical (arithmetic and logical) computations.

I hope you understand what is a computer.

Introduction:

A computer is an electronic device control data or information. It can store, recover, and process information.

These days, a computer can be used to type reports, send emails, play games, and browse the Web. It can likewise be used to edit or make spreadsheets, presentations, and even videos.

But the evolution of this complex system begins around 1940 with the first Generation of Computer and evolving ever forward.

There are five generations of computers.

FIRST GENERATION

• Introduction:

  1. 1946-1959 is the duration of first generation computer.
