While we live in a world full of technology and devices, there was a time where those were not part of our daily routine. As humans beings we are constantly developing and learning new things about technology and the biggest contributor to those devises come from the development of computers. There are many inventors that contributed to it. Each part of a computer was invented by different contributors and each is considered a separate invention.
The first generation of computers was called Vacuum Tubes. They were used from1940 to 1956, they were expensive to operate, used a lot of electricity and cause a lot of heat. In 1951 the first commercial computer called the UNIVAC was use for the US census. As time passed the second generation came around 1956 to 1963 when the transistors replaced vacuum tubes allowing the computers to be faster, smaller and more energy efficient. The third generation occurred from 1964 to 1971 based on the development of the integrated circuits. The transistors used before became smaller and placed on silicon chips. The increase of the speed plus the substitution of punched cards for keyboards and monitors made computers accessible to more people. The fourth generation started on 1971 to the present introducing microprocessors allowing all input and output controls of the computer to be on a single chip.
I was born in 1978 and I remember when in 1981 IBM introduced computers to use at home. It was the first time that I had unlimited access to a PC (personal computer) and it was exciting to learn the system. Eventually other accessories became part of the use of the computer that make our life easier at work and home. Today another generation is being developed using artificial intelligence. It is a matter of time that we will see how computers will evolve again making information more accessible and efficiency the first priority for our advantage. I can’t wait to experience what will be next as I know most of people is excited to...
