Grimsdale and Webb build early transistorized computer
Working under Tom Kilburn at England’s Manchester University, Richard Grimsdale and Douglas Webb demonstrate a prototype transistorized computer, the “Manchester TC”, on November 16, 1953. The 48-bit machine used 92 point-contact transistors and 550 diodes.
What did IBM start out?
the Computing, Tabulating & Recording Company
IBM is, perhaps, the best known computer company in the world. It began as the Computing, Tabulating & Recording Company (C-T-R) founded by Herman Hollerith in the late 1800s. Their first large contract was to provide tabulating equipment for the tabulation and analysis of the 1890 US census.

What was Z1 in 19th century?
The “Z1” was the first freely programmable computer in the world which used Boolean logic and binary floating-point numbers, however it was unreliable in operation. It was completed in 1938 and financed completely from private funds.
Was developed in the 1950s by IBM?
IBM made a number of key technological changes in the decade of the 1950s. In 1952, the company introduced the IBM 701, its first large computer based on the vacuum tube.
What did the IBM 701 use for processing?
The 1953 built 701 had electrostatic storage tube memory, used magnetic tape to store information, and had binary, fixed-point, single address hardware. The speed of the 701 computers was limited by the speed of its memory; the processing units in the machines were about 10 times faster than the core memory.
What was the IBM 701 used for?
Introduced in 1952, the 701 was designed for scientific work and research, which led to the development of the FORTRAN programming language. Nineteen machines were built, a record volume for such a computer in that era.
Were there computers in the 60s?
By the mid 1960’s the computer was seen as an information processor, being part of a management information system. Advertisers stressed the “flexibility, versatility, expandability, and …the capacity of the computer to make logical decisions.” IBM in particular was very successful during this decade.

What generation is IBM 360 computer?
Third generation computers
Third generation computers. The computers introduced in the mid 1960s, such as the IBM 360 family, were called “third generation” computers. Third generation computers were important because each computer in a family had the same architecture.
