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 term "computer", in use from the early 17th century (the first known written reference dates from 1613), [1] meant "one who computes": a person performing mathematical calculations, before electronic calculators became available.
The plan was to allow the computer to scale to 1 teraFLOPS. [ 10 ] [ 12 ] In 1993 the PARAM 9000 series of supercomputers was released, which had a peak computing power of 5 GFLOPS. [ 1 ] In 1998 the PARAM 10000 was released; this had a sustained performance of 38 GFLOPS on the LINPACK benchmark.
After the "computer-on-a-chip" was commercialized, the cost to produce a computer system dropped dramatically. The arithmetic, logic, and control functions that previously occupied several costly circuit boards were now available in one integrated circuit which was very expensive to design but cheap to produce in large quantities.
The following is a list of people who are considered a "father" or "mother" (or "founding father" or "founding mother") of a scientific field.Such people are generally regarded to have made the first significant contributions to and/or delineation of that field; they may also be seen as "a" rather than "the" father or mother of the field.
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.
