Abacus
First practical idea of abacus made by the Babylonians in the 1300 BC. Abacus was perfected by Chinese and was most popular during the Ming Dynasty (1368 AD-1644 AD) -
Computer Language
During the 17th century, there were a lot of different machines built to to perform calculations but one of the most famous one is Pascaline. His machines could add up to eight digit numbers(99,999,999). -
Napier's Bones
A Scottish mathematician invented a set of rods, also known as "Napier's Bones", that could be used to solve complex calculations. These were used to divide and multiply. -
The Jaquard Loom
In Lyon, France Joseph Marie Jacquard (1752-1834) demonstrated in 1801 a loom that enabled unskilled workers to weave complex patterns in silk. The Jacquard Loom is controlled by a chain of multiple cards punched with holes that determine which cords of the fabric warp should be raised for each pass of the shuttle. -
Babbage Engine
Computer pioneer, Charles Babbage, designed the first automatic computing engines. He invented computers but failed to build them. The machine was called the "difference machine". -
Punched Card Calculator
In 1890, the first punched card calculator was invented by Herman Hollerith for the U.S. Census. The1880 census took them more than seven years to count but with this new invention, 1890 only took six weeks. -
Audion
The Audion was an electronic detecting or amplifying vacuum tube invented by American electrical engineer Lee de Forest in 1906. It was the first triode, consisting of an evacuated glass tube containing three electrodes: a heated filament, a grid, and a plate. -
Program Controlled Calculator
In 1943, a computer at Harvard University by Howard H. Aiken was the first program controlled calculator. It worked on punched cards or paper tape. -
Colossus
A computer called the Colossus was made by Tommy Flower. Tommy Flowers spent eleven months designing and building Colossus at the Post Office Research Station, Dollis Hill, in North West London. It was a general purpose machine that was very fast ten were built but after the WWII, they were all destroyed. Britain were afraid that other nations would use it against them. -

Computer Language
during the years of 1945 and 1975, computer languages were written. Grace Hopper, ex Navy, created a high level compiler. -
Transistor
The transistor was successfully demonstrated on December 23, 1947 at Bell Laboratories in Murray Hill, New Jersey. Bell Labs is the research arm of American Telephone and Telegraph (AT&T). The three individuals credited with the invention of the transistor were William Shockley, John Bardeen and Walter Brattain. -

Integrated Circuit and Modern Computer Chip
The first integrated circuit was made in the 1958 and it led the introduction to the modern computer chip that contains the equivalent power of a million transistors. This is what we call today, a microprocessor. -
Cray 1
The Cray-1 was the first supercomputer to successfully implement the vector processor design. These systems improve the performance of math operations by arranging memory and registers to quickly perform a single operation on a large set of data. Cray 1 was delivered in 1976 -
Apple Computers
The Apple Computer 1, originally released as the Apple Computer and known later as the Apple I, or Apple-1, is a desktop computer released by the Apple Computer Company (now Apple Inc.) in 1976. It was designed and hand-built by Steve Wozniak. The idea of selling the computer came from Wozniak's friend Steve Jobs. -
First Personel Computer
The Commodore PET (Personal Electronic Transactor) introduced. The first of several personal computers released in 1977, the PET comes fully assembled with either 4 or 8 KB of memory, a built-in cassette tape drive, and a membrane keyboard. The PET was popular with schools and for use as a home computer. -
8086 Microprocessor
An 8080 microprocessor is an 8-bit parallel CPU, and this microprocessor is used in general purpose digital computer systems.It is made up on a single large-scale integration chip using Intel's N-channel silicon gate MOS process. It was introduced in 1978
