History of computer

There is no proof that when the development of computers started or how old the history of computer is.

The history of computers is very old, the use of computers has been going on since time immemorial when there was a great shortage of such equipment with the help of which he could count his cattle, and fish and understand the calculations. Find it.
To make it convenient for you, I have divided my article into many parts, so you can click on these and go directly to any title.

Some experts have the same opinion – “Necessity is the mother of invention”.
That is, once man needs something he has made the object of his desire, within the same approach, even within a period, humans have done a lot of analysis regarding the count of their oxen and a ‘count’. System’ developed Pebbles. And at that time humans started learning calculus through pebbles and this is exactly where the phenomenon of PC started hence the history of PC started from here.
3000 BCE, China developed the abacus which was the primary system of numbers created by humans.

History of computer (when the computer was made)

The technology used in modern computers is hardly 50 years old and I, you, all of us, the computer we are using, the development of these computers has also happened very recently, you do not need to be so shocked, I have read all below here.
