The modern computer took its shape with the arrival of your time. It had been around 16th century when the evolution of the computer started. The initial computer faced many changes, obviously for the betterment. It continuously improved itself in terms of speed, accuracy, size, and price to urge the form of the fashionable day computer. This long period is often conveniently divided into the subsequent phases called computer generations: First Generation Computers (1940-1956) Second Generation Computers (1956-1963) Third Generation Computers (1964-1971) Fourth Generation Computers (1971-Present) Fifth Generation Computers (Present and Beyond) Before there are graphing 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. 1. Abacus (ca. 2700 BC) 2. Pascal’s Calculator (1652) 3. Stepped Reckoner (1694) 4. Arithmometer (1820) 5. Comptometer (1887) and Comptograph (1889) 6. The Difference Engine (1822) 7. Analytical Engine (1834) 8. The Millionaire (1893) First Generation Computers: Vacuum Tubes (1940-1956) The technology behind the primary generation computers was a fragile glass device, which was called vacuum tubes. These computers were very heavy and really large in size. These weren’t very reliable and programming on them was a really tedious task as they used high-level programming language and used no OS. First-generation computers were used for calculation, storage, and control purpose. They were too bulky and large that they needed a full room and consume rot of electricity. Main first generation computers are: ENIAC: Electronic Numerical Integrator and Computer, built by J. Presper Eckert and John V. Mauchly was a general-purpose computer. It had been very heavy, large, and contained 18,000 vacuum tubes. EDVAC: Electronic Discrete Variable Automatic Computer was designed by von Neumann. It could store data also as instruction and thus the speed was enhanced. UNIVAC: Universal Automatic Computer was developed in 1952 by Eckert and Mauchly.
