  • Colossus

    Colossus
    Colossus was the world’s first electronic, programmable computer created by Tommy Flowers. Colossus reduced the time to work out the Lorenz chi-wheel settings and enabled more messages to be deciphered and the whole code-breaking operation to be accelerated. British code breakers used Colossus for cryptanalysis during World War II. These messages were sent between the German High Command, and army field commanders. Reading these messages helped the Allies to win the war.

  • ENIAC

    ENIAC
    Designed by John Mauchly and J. Presper Eckert, was the first general purpose programmable electronic computer,Electronic Numerical Integrator and Computer (ENIAC) was the fastest computational device of its time, able to do 5,000 additions per second, but because it had no internal storage, it had to be programmed manually for each new set of calculations. ENIAC arguably accomplished something more important: It sparked the imagination of scientists and industrialists.

  • First Trackball (Mouse)

    First Trackball (Mouse)
    It was invented by Ralph Benjamin. A trackball is an input device used to enter motion data into computers or other electronic devices. It serves the same purpose as a mouse, but is designed with a moveable ball on the top, which can be rolled in any direction.
    It allowed human beings to connect thoughts and ideas with a computer in a way that was highly intuitive. But it had also a major impact on the design of the computer interface.

  • SSEM

    SSEM
    The Manchester Baby, also called the Small-Scale Experimental Machine (SSEM), was the first electronic stored-program computer. It was built at the University of Manchester by Frederic C. Williams, under the leadership of Max Newman. SSEM contained a 32-bit word length, single address format order code, a memory of 32 words, and computing speed of around 1.2 milliseconds per instruction.

  • First Assembler: Initial Orders

    First Assembler: Initial Orders
    Initial orders written by David Wheeler. It was implemented in a read-only memory formed from a set of rotary telephone selectors, and it accepted symbolic instructions. Each instruction consisted of a one letter mnemonic, a decimal address, and a third field that was a letter. The first assembler was designed for EDSAC
