- The Analytical Engine (First mechanical computer)

Charles Babbage comes up with the first proposal for a mechanical computer in the year of 1837.

The analytical engine contained an ALU (Arithmetic Logic Unit) and integrated memory.

Funding issues delayed building of the machine until 1910 when Henry Babbage (Charles Babbage's youngest son) managed to assemble enough of the machine so that it performed very basic calculations.

- The Z1 (First programmable computer)


Created by Konrad Zuse and is considered to be the first programmable and functional computer.

The Z1 consisted of about 20,000 parts and weighed 1,000 kg. It had a clock frequency of 1Hertz and a memory which consisted of 64 words.



- The Collosus (First electronic programmable computer)

Developed by Tim Flowers and was used to help British code breakers read encoded German messages during World War II.

Collosus was capable of reading 5,000 characters per second from a paper tape.

During the course of the war, Collosus successfully decrypted 63 million characters of encoded German messages.

- The ENIAC (First digital computer)

The ENIAC is considered to be the worlds first fully functional digital computer.

Invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and was completed in 1946.

The ENIAC occupied 1,800 square feet and weighed over 50 tons.



- EDSAC (First stored program computer)

Made in Britain and is considered to be the first computer that was capable of storing and running a program.

The computer performed its first calculation in 1949.

EDSAC is also credited as being the first computer that ran a graphical computer game.


- The Z4 (First commercial computer)

The Z4 is credited as being the first commercial computer after being sold to a Swiss mathematician in 1950.

The machine was capable of performing a range of instructions including square root, MAX, MIN and sign.

The Z4 had a clock frequency of 40 Hertz and could perform roughly 1000 operations per hour.


- The IBM 701 (First mass produced computer)

IBM released their first electronic computer and the worlds first mass produced computer.

The 701 could perform 2,200 calculations per second and had a memory capacity of 2048 words.

The machine sold a total of 19,701 units.


- Whirlwind (First computer with RAM)

Researchers at MIT (Massachusetts Institute of Technology) introduced the Whirlwind machine.

Whirlwind was the first computer that made use of RAM and used real-time graphics to output data onto a screen.
