Charles Babbage. Since then computers have undergone many transformational
changes in size and processing speed. Modern computers are capable of taking human
instructions in a form of language called programming language and delivering output in

Computers are like a big dictionary and large storage devices which we use to save any
type of large amount of data like information, study materials, projects, photos, images,
video, audio, songs, clips, games, and many more.

to forecast the information about weather, in printing books, newspapers, diagnosing
