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 ...

Of the latter figure, 75% were professional or work related, while the rest were sold for personal or home use. About 81.5% of personal computers shipped had been desktop computers, 16.4% laptops and 2.1% servers. The United States had received 38.8% (394 million) of the computers shipped, Europe 25% and 11.7% had gone to the Asia-Pacific ...
[1] [2] By contrast, software is a set of written instructions that can be stored and run by hardware. Hardware derived its name from the fact it is hard or rigid with respect to changes, whereas software is soft because it is easy to change. Hardware is typically directed by the software to execute any command or instruction.
Information technology (IT) is a set of related fields that encompass computer systems, software, programming languages, data and information processing, and storage. [1] IT forms part of information and communications technology (ICT). [2]
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.
Data General Nova, serial number 1, on display at the Computer History Museum. A minicomputer, or colloquially mini, is a type of smaller general-purpose computer developed in the mid-1960s [1] [2] and sold at a much lower price than mainframe [3] and mid-size computers from IBM and its direct competitors.
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.
