History of computers
Throughout the history of computers, much advancement has been made, and continues to be made. The first known computing device was the abacus, which we think was created around 2400 BC by the Babylonians. Another early computing device was the ancient Greek Antikythera mechanism, used to calculate the movements of planets, from 87 BC.
The first calculating clock, which could add and subtract, was created in the early 17th century by Wilhelm Schickard. Also in the 17th century and 19th century, more advanced calculating machines were invented. Charles Babbage created one of these machines in 1833, which allowed input, storage and output in. In 1891, the first strong calculating machine was created by William S. Burroghs, who also started the office calculation business.
What would the history of computers be without the founder of IBM? Herman Hollerith came up with an idea for using punched cards as a means of storage and transportation of information in 1886. The computers developed to read these cards did a large amount of the first computing for businesses.
Some believe the first high-speed electronic computer in the history of computers was the ENIAC, developed for the military, was created in 1942. There was a debate about this, however, that ended in favor of John V. Atanasoff, who had created a similar but simpler machine in the 1930's.
Through the 1940's and 1950's, computer technologies became faster, smaller, and added more memory capabilities. The history of computers as we know them today seems to have begun in the 1960's, when computers became commercially available. In the 1970's and 1980's, computers became less expensive, and started to gain popularity for personal use. Since the creation of Apple in 1976 and Microsoft Windows in 1985, computers have been becoming more and more advanced. It is said that if you buy a computer today, it will be outdated next month!
