First generation computer: Before computers

Before computers, we used calculators, spreadsheets, and computer algebra systems, mathematicians and inventors searched for solutions to ease the burden of calculation. Below are the 8 Mechanical Calculators before modern computers were invented. Abacus (ca. 2700 BC) Pascal’s Calculator (1652) Stepped Reckoner (1694) Arithmometer (1820) Comptometer (1887) and Comptograph (1889) The Difference Engine (1822) Analytical Engine (1834) The Millionaire (1893) First Generation Computers The ... First Generation (1940s-1950s): The first generation of computers used vacuum tubes as the primary electronic component. These machines were large, expensive, and consumed a significant amount of electricity. They were mainly programmed using machine language and assembly language. Examples include the ENIAC and UNIVAC I. The first generation of computers relied on vacuum tubes, which were used for both circuitry and memory storage. These early machines were massive and primarily used for scientific and military applications. First Generation of Computers and their Characteristics The era of First Generation of Computers was from 1940 to 1956.
