Ferranti Mark 1: 1951 9: First commercially available stored program computer, based on Manchester Mark 1. UNIVAC I: 1951 46: First mass-produced stored-program computer. Used delay-line memory. LEO I: 1951 1 First computer for commercial applications. Built and used by J. Lyons and Co., a restaurant and bakery chain. Based on EDSAC design. IBM ...
The Manchester Mark 1 was dismantled and scrapped in August 1950, [28] replaced a few months later by the first Ferranti Mark 1, the world's first commercially available general-purpose computer. [1] Between 1946 and 1949, the average size of the design team working on the Mark 1 and its predecessor, the Baby, had been about four people.
With an operating speed of 1 MHz, the Pilot Model ACE was for some time the fastest computer in the world. [52] [60] Turing's design for ACE had much in common with today's RISC architectures and it called for a high-speed memory of roughly the same capacity as an early Macintosh computer, which was enormous by the standards of his day. [52]
The main improvements over the Manchester Mark 1 were in the size of the primary storage (using random access Williams tubes), secondary storage (using a magnetic drum), a faster multiplier, and additional instructions. The basic cycle time was 1.2 milliseconds, and a multiplication could be completed in about 2.16 milliseconds.

A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals.
The Computer History Museum claims to house the largest and most significant collection of computing artifacts in the world. [a] This includes many rare or one-of-a-kind objects such as a Cray-1 supercomputer as well as a Cray-2, Cray-3, the Utah teapot, the 1969 Neiman Marcus Kitchen Computer, an Apple I, and an example of the first generation of Google's racks of custom-designed web servers.
