Computer memory timeline part 1 of 4 from 1833 to 1951 at Timeline Help. Ever wondered how the data on your computer are stored? The storage or memory devices have a long history, back to the 19th century. All computer components and functions, for example recording devices, get their instructions and data from chips, to put it simply. Here's how it started, I wrote the history of inventions, patents and improvements down in a computer memory timeline.

- 1833 - 1932 - 1936 - 1939 - 1941 - 1944 - 1947 - 1948 - 1949 - 1950 - 1951

British mathematician Charles Babbage constructs the first punched card machine with a the memory store, he called it the Analytical Engine. Austrian inventor Gustav Tauschek builds a drum memory. German computer pioneer Konrad Zuse patents a mechanical combination memory with sliding metal parts. American physicists John Atanasoff and Clifford Berry builds the electronic 50-bit words digital memory Atanasoff–Berry Computer ABC. German inventor Helmut Schreyer develops the neon lamp memory Z3. Hungarian-born American mathematician John von Neumann defines that a computer is a device that has a electronic binary number system, an internal memory and a programthat can execute and more tasks at the same time. German-born American Frederick Viehe, China-born American An Wang and American engineer Kenneth Olsen indepentently invent the magnetic core memory with pulse transfer controll. American computer engineer Jay Wright Forrester invents the magnetic random-access coincident-current drum. IBM uses the punched taped vacuum tube Selective Sequence Electronic Calculator (SSEC) to show scientific data on a public wide screen. Jay Wright Forrester improves the magnetic core computer memory further. British computer scientist Maurice Vincent Wilkes builds the first practical stored-program computer EDSAC with vacuum tube memory. English cryptographer Alan Turing builds a large-scale digital calculator, containing a delay line computer memory size of 352 32-digit words. First commercial computer, the Ferranti Mark I, with 256 40-bit main memory and a 16K word drum memory. Jay Forrester patents the matrix core memory. Remington Rand builds the thousand 12-digit words UNIVAC I aka IBM UNIVAC for the U.S. Census Bureau with a mercury delay lines memory and magnetic tape storage. Jay Forrester develops the MIT Lincoln Laboratory Whirlwind with a computer memory size of 2048 16-digit words and a magnetic drum, cathode ray tube, and tape storage.
