who is the inventor of computer?& where he lived?

Question

today computer is a very usefull & important electronic device.

Answer 1

Feel free to open links and decide who gets all of the credit. No one person made it what it is today is was a series of inventions that led to this wonderful machine.
Good luck!

Fascinating facts about Douglas Engelbart
inventor of the computer mouse in 1968.

Douglas Engelbart had invented a number of interactive, user-friendly information access systems that we take for granted today: the computer mouse, windows, shared-screen teleconferencing, hypermedia, GroupWare, and more.

Answer 2

It is difficult to define any one device as the earliest computer. The very definition of a computer has changed and it is therefore impossible to identify the first computer. Many devices once called "computers" would no longer qualify as such by today's standards.

Originally, the term "computer" referred to a person who performed numerical calculations (a human computer), often with the aid of a mechanical calculating device. Examples of early mechanical computing devices included the abacus, the slide rule and arguably the astrolabe and the Antikythera mechanism (which dates from about 150-100 BC). The end of the Middle Ages saw a re-invigoration of European mathematics and engineering, and Wilhelm Schickard's 1623 device was the first of a number of mechanical calculators constructed by European engineers.
