Introduction
A computer is an electronic device developed by "Charles Babbage". A Computer is an electronic device that is used to perform complex arithmetical and analytical functions, much beyond the natural capacity of humans. Computers are highly efficient devices and perform really fast and accurate. Output generated by a computer is precise and there is no possibility for an error except human error. History of Computer
The history of the computer is long and has many phases of development. Some consider that an early calculating device named ‘Abacus’ led further to the invention of calculator and computer. Though, the abacus was only a mechanical device consisting of wooden beads those can move on thin rods or wires. Even to this day, ‘Abacus’ has retained its original form and doesn’t contain any electronic or electrical part. The Difference Engine
The first-ever mechanical computer was developed by Charles Babbage, no earlier than 1822. This machine was called the ‘Difference Engine’. Charles Babbage is often referred to as ‘Father of the computer’ though; his invention was completely different from the modern-day computers. The analytical Engine this machine was a proposal made by Charles Babbage in 1837. It contained ALU (Arithmetic and Logic Unit), flow control, punch card, and integrated memory. It was the first concept to make the general-purpose computer. But unfortunately, due to financial problems, this concept of Babbage, never materialized in his life span. However, his son Henry Babbage was able to develop a portion of the machine as conceptualized by Charles Babbage, no sooner than in 1910. The First Ever Programmable Computer, this computer was developed by a German inventor named Konrad Zuse. He developed it during 1936-1938, in his parents’ living room, while he was around 26 years old. ‘Z1’ was the first binary programmable computer and the actual predecessor of modern-day computers. The Turing Machine this machine was proposed by Alan Turing in 1936. Turing was a mathematician and a computer scientist based in the United Kingdom. A Turing machine was capable of simulating and algorithm and printing symbols on a paper tape. "The Colossus" the Colossus was a set of machines developed by the British during World War II. These were developed by the British code breakers, during 1943-1945, to read high-level messages of the German Army during the Second World War. First Digital Computer the first digital computer used plus 300 vacuum tubes and could perform mathematical calculations and Boolean logic. It was also called Electronic Numerical Integrator and Computer, after its two inventors, John Vincent stand-off and Cliff Berry. They developed it from 1937-1942 at Iowa State College, which is now Iowa State University. First Electronic Computer (EN IAC)
EN IAC is an abbreviation of Electronic Numeric Integrator and Calculator, developed in 1943, at the University of Pennsylvania by J. Prosper Eckert and John Muchly. It was colossal, heavy and required 1800 square feet. It also used around 18,000 vacuum tubes and weighs approximately 50 tons. This was the first fully functional digital computer.
First Computer Company the first computer company was founded in 1949, and it was named Electronics Control Company. It was founded by two persons who helped create the EN IAC – J. Prosper Eckert and John Muchly. Conclusion Modern computers have evolved through hundreds of years to reach the efficiency and shape that we see today. But, evolution is not over yet and will continue for centuries to come with the help of humans innovating to bring new technological advancements.
