Computers have been unified into almost everyone’s life. As we know every human uses a computer, laptop or smart phones this day. A computer makes every work so easy, but that will be not possible if a computer was not found. This paper is about the history of inventing the computer. It will explain about the generation of computers, when it was found and the uses and languages of a computer. Inventors have gifted us revolutionized technology. Whether it is a anything, cell phone, TV, computers, laptop, radio, etc. They have never been miser in enhancing the society with life transforming inventions. Many invention took place on 20th century. One legislate invention has been of computer. Not one but there are many geniuses behind the…show more content…
The first computer’s input was based on punched cards and paper tape, and output was displayed on printouts. The earliest electronic computers were not able to use by everyone. They were expensive and to keep them running it needed a team of engineers and specialists of programming. The most famous Electronic Numerical Integrator Analyzer and Computer (ENIAC), was built at University of Pennsylvania. It can do calculation for the US military during world war II. The ENIAC weighed 30 tons, took up nearly 2,000 square feet of floor space and it cost $500,00. From outside it was covered in a tangle of cables, hundreds of blinking lights and nearly 6,000 mechanical switches to operators. On the inside, 18,000 vacuum tubes carried electrical signals from one part of the machine to another. When the ENIAC was presented to the public in 1946, it made a great impact in the world of scientific, military and industrial because of its speed. Addition or subtraction of two ten digit numbers could be solved in a 5000 per second. This was much faster and accurate than any other machine of that time. It was to perform highly repeated computations using this setup. The second generation of computer was Transistors, which is replaced vacuum tubes in 1956 to 1963. The transistors were smaller and more smooth. In 1948, Bell labs introduced the first Transistors. Transistors first used in 1950s but invented in 1947. The transistor was far admirable to vacuum tube. It
