  • The Beginning.

    Charles Babbage starts planning and conceptualising the first mechanical computer.
  • The First Mechanical Computer.

    Henry Babbage, Charles Babbage's youngest son, completed a part of his father's machine. This machine was able to perform basic and simple calculations.
  • Period: to

    First Generation of Computers.

    The first generation of computers contained vacuum tubes and magnetic drums. They were traditionally the size of large rooms.
  • The Z1.

    The Z1 was the first computer that ran on binary code. This forms the basis of modern-day computers.
  • The ENIAC.

    The ENIAC was the first computer ever built. It was took three years to build, commencing in 1943 and ending in 1946. It was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania. It was approximately 1800 feet in volume.
  • Period: to

    Second Generation of Computers.

    The Second Generation of Computers used transistors, which were more reliable. over 100 different programming languages were developed during this period and stapes and discs became in use along with printers.
  • Period: to

    Third Generation of Computers.

    With this generation of computers, computers became smaller in size, more powerful and more reliable. They became able run many different programs at the same time.
  • Invention of the CPU.

    The Central Processing Unit was invented by Ted Hoff and Stan Mazor. It consisted of 4 chips.
  • Osbourne 1

    Osborne 1, the first laptop, was invented by Adam Osborne. It cost $1,795 and came bundled with $1500 worth of programs.
