First generation computer: Introduction to all the generations of computers

Introduction to all the generations of computers from 1st to 5th with pictures by explaining the information about their characteristics, components, examples. Learn about the history and design of vacuum-tube computers, the first generation of electronic computers that used vacuum tubes for logic circuitry. Find out how they evolved from mechanical aids to computation, and what innovations they introduced in memory, programming, and graphics. These machines, known as first-generation computers, were truly groundbreaking, even though they seem very different from the computers we use today. The first generation of computers (1940s-1950s) used vacuum tubes. 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 ...
