- The word ‘computer’ has a very interesting origin. It was first used in the 16th century for a person who used to compute, i.e. do calculations.
- The word was used in the same sense as a noun until the 20th century. Women were hired as human computers to carry out all forms of calculations and computations.
- Since the evolution of humans, devices have been used for calculations for thousands of years. One of the earliest and most well-known devices was an abacus.
- By the last part of the 19th century, the word was also used to describe machines that did calculations. The modern-day use of the word is generally to describe programmable digital devices that run on electricity.
- 1st Generation: This was from the period of 1940 to 1955.This was when machine language was developed for the use of computers.They used vacuum tubes for the circuitry. For the purpose of memory, they used magnetic drums. These machines were complicated,
- 2nd Generation: The years 1957-1963 were referred to as the “second generation of computers” at the time. In second-generation computers, COBOL and FORTRAN are employed as assembly languages and programming languages.
- 4th Generation: The invention of the microprocessors brought along the fourth generation of computers. The years 1971-1980 were dominated by fourth generation computers. C, C++ and Java were the programming languages utilized in this generation of computers.
- 3rd Generation: The hallmark of this period (1964-1971) was the development of the integrated circuit. A single integrated circuit (IC) is made up of many transistors, which increases the power of a computer while simultaneously lowering its cost.
- 5th Generation: These computers have been utilized since 1980 and continue to be used now. This is the present and the future of the computer world. The defining aspect of this generation is artificial intelligence. The use of parallel processing and superconductors are making this a reality and provide a lot of scope for the future.
