BRIEF HISTORY AND ORIGIN OF COMPUTERS.
Computers have been around for a long time. Going back in history, some people believed that the abacus was the true first computer. The first abacus is believed to come into existence between 2700-2300 BC and was created by the Sumerians so that they could count faster, and have evolved through the year. The term "computer" came out around 1613. People who performed computations or calculations were often referred to as computers.
One of the first major counting problems in History was the census. The first census was taken George Washinton was in office in 1790. In 1790, there were so many people that it took more than seven years to add up all of the numbers for the census.
The government was so much frustrated that it took so much time to tabulate. As the country grew, it became harder and harder to count all the people and it took longer and longer. The need for speed kept on growing. In 1890, a young engineer named Herman-Hollerith designed a punch card system to tally up the 1880 census information. The census calculation only took three years and saved the government $5 million. For more details, visit https://kobsworld.com.
