1. Charles Babbage (26 December 1791- 18 October 1871)
In his early years, the numerical tables which calculated by humans has a lot of mistakes. Charles Babbage came up with a idea to produce the first mechanical computer to help get rid of the errors. He had invented Difference Engine, a device that able to carry out many processes at a same time. However the machine was not completed. After this, he was the one who responsible to invent Analytical Engine as it was the first programmable computer ever existed. However, before Charles Babbage able to finish and built his every design, he was died. Although he unable to create his computer, he played important role in contributing to the world of computer.
2. John von Neumann (28 December 1903-8 February 1957)
John von Neumann was a famous mathematician and remarkably made his name recognised on the field of computer science. He came up with computer architecture which was then named after him. His computer architecture stated that in a same address space, a computer’s memory can store both data and program. Hence, his architecture are making the computers more simpler and faster to program.
3. Alan Turing (23 June 1912 - 7 June 1954)
Alan Turing was the one who invented an electromechanical machine called Bombe. The function of the machine was to assist code-breaker device to break codes faster. It plays important roles in breaking German’s Enigma codes during World War II. After the code breaking team providing a menu, the Bombe operators will set up the machine and calculate Enigma settings. The machine created had helped in saving many precious lives during World War II and shortening the period of war. He also undergoes the Turing Test, which was aimed to test artificial intelligent. Therefore, he was the first to figure some ways to test artificial intelligent. However, in later years, he was prosecuted for homosexual acts. In 1954, he committed
