Computing hardware is basically a process of information processing. It means that input is equal to output. The history of computing hardware includes the hardware, it’s architecture, and it’s impact on software. Computing hardware has become a source of computation, such as automation, communication, control, entertainment, and education. Computation machines have been used to aid computation for thousands of years. The very first and basic computing device was invented by Romans in 2400 BC known as the abacus.
Some analog computers were invented in ancient times to perform astronomical calculations. The first digital calculator was invented in 1623 by a German mathematician. By the 1900s, earlier mechanical calculators, cash registers, accounting machines, and so on were redesigned. Over time, during the 1950s and 1960s a several different brands of mechanical calculators introduced on the market. After then analog computers were introduced. These analog systems work by creating electrical analogs of other systems.
After analog technology of computing then digital computing was introduced in early 90s. Charles Babbage was titled as father of computer. The commercial development of computers was performed in the decade of 1940s to 1950s. A British catering company famous for its teashops but with strong interests in new office management techniques, decided to take an active role in promoting the commercial development of computers. By this time very few people started to use computers for their jobs.
In the past computers were very big in size but now-a-days these machines are changed into smaller machines. For the first time IBM introduced a smaller, more affordable computer in 1954 that proved to be very popular.
