Baby is the world’s first program can be stored in the memory of the computer.

65 years ago June 21, Manchester Small-scale testing machine (Manchester Small Scale Experimental Machine) to become the world’s first program can be electronically stored in the memory of the computer, nicknamed “Baby.” This is an extremely important moment, this is the first use of the concept of stored program (stored program concept) computers, and later became the basis for the modern computer.

Early computer commands them are set in the physical hardware, or require the use of punched paper tape or card input. If you want to change its function, you have to re-design the circuit, or change the physical storage interface does not. “Baby” marked a new era of computers, some people call it the “Software birth,” In this new era, the era before replacing the program far easier to just update the electronic memory. Both instructions and data are stored in the “Baby” in memory, the contents of which can automatically calculate the speed of the changes electronically.

“Baby” by the University of Manchester Freddie Williams (“Freddie” Williams), Tom姆基尔伯恩 (Tom Kilburn) and Ji Erfu soil Tyre (Geoff Tootill) development, on all sides over five meters long and weighs 1 tonne. Its purpose is to serve as the ” Williams – Kilburn tube “(Williams-Kilburn tube) test bed, and therefore would have” Baby “nickname,” Williams – Kilburn tube “is a use of the cathode ray tube (cathode ray tube, CRT) storing binary codes (binary digits, “bits”) approach. Up until now, the computer does not electronically access the data stored in the form of low-cost and flexible way.

Technically speaking, “Williams – Kilburn tube” is the first random access memory (RAM) in the form, Baby’s memory to a “Williams – Kilburn tube” composition, can be stored maximum 1,024 bits, which is 128 bytes of data, compared to the number of gigabytes of modern computers of RAM, as Baby memory 1,000,000,000 times.

Baby born purpose is to prove a concept, rather than the actual computing tasks. So once it demonstrates the reliability of the new memory, the experimenter’s attention shifts to use the same concept to build a stronger performance, more practical machine, later led ” Manchester Mark 1 “(Manchester Mark 1) was born , that is, in February 1951 sold the world’s first commercial computer Ferranti Mark 1 prototype.

Although Baby’s original machine has ceased to exist, but in the Manchester Museum of Science and Industry (Museum of Science and Industry, MOSI) still exhibits a working replica of Baby, reflecting the degree of evolution of the computer.
