Meanwhile, what is computer? A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. Let’s get to know the history of computer
​
History of the computer:
-
1642 - Adding machines were the first computers. French mathematician Blaise Pascal invented the arithmetique – a machine that could add numbers up to 1 million.
-
1671 - German mathematician Gottfried Wilhelm von Liebnitz explored binary arithmetic (Which is the system modern computers are based on).
-
1888 - Herman Hollerith invented a computer that used punch cards and electrical circuits to do calculations.
-
1940’s - Howard Aiken developed the first binary system-based computer at Harvard, a few years ENIAC was constructed
-
1950’s- Inventions of transistor, integrated circuits, and silicon chips let to smaller, cheaper and easier to maintain computers.
-
1970’s - PC for home and business use with prepackaged software emerges
