History of computers

  • Period: to

    1st generation

    -Vacuum tubes (small wire tube)
    -Used magnetic drums for memory
    -Lot of energy
    -Information was displayed in bulbs (bulb=bit. if it was 1 was on, and if it was 0 it was off)
    -The computers were enormous, each one occupied three rooms
    -They required 24 hours of attention
  • Period: to

    2nd generation

    -Transistors
    -The invention of the transistor replaced the vacuum tubes and ashed in the 2nd generation of computers
    -Were faster, cheaper and smaller, more energy efficient and more reliable than the 1st generation
    -In this generation was created the first computer game, called Spacewar
  • Period: to

    3rd generation

    -Was invented the microchip, a transistor which in each one had a complete circuit inside
    -Had integrated circuit. Its development was the homework of the third generation.
    -The transistors were miniaturized and placed on a silicon chip called the semiconductor, which increased the speed and efficiency
  • Period: to

    4th generation

    -In this generation thousands of integrated circuits were built onto a single silicon chip
    -It worked faster, and were cheaper and smaller.
    -One microprocessor=10 millions of transistors.
    -Internet was introduced on the computers
  • Period: to

    5th generation

    -Computers have come a long way today, and will continue to do, so thanks to artificial intelligence (AI) technology, which will solve all kinds of tasks.
    -There're robots now.
    -They'll change the actual screams to 3D technology
