BBC Micro

The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by Acorn Computers in the 1980s for the BBC Computer Literacy Project. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating systems. An accompanying 1982 television series, The Computer Programme, featuring Chris Serle learning to use the machine, was broadcast on BBC2.

After the Literacy Project's call for bids for a computer to accompany the TV programmes and literature, Acorn won the contract with the Proton, a successor of its Atom computer prototyped at short notice. Renamed the BBC Micro, the system was adopted by most schools in the United Kingdom, changing Acorn's fortunes. It was also successful as a home computer in the UK, despite its high cost. Acorn later employed the machine to simulate and develop the ARM architecture.

While nine models were eventually produced with the BBC brand, the phrase "BBC Micro" is usually used colloquially to refer to the first six (Model A, B, B+64, B+128, Master 128, and Master Compact); subsequent BBC models are considered part of Acorn's Archimedes series.

Bowling is a target sport and recreational activity in which a player rolls a ball toward pins (in pin bowling) or another target (in target bowling). The term bowling usually refers to pin bowling (most commonly ten-pin bowling), though in the United Kingdom and Commonwealth  countries, bowling could also refer to target bowling, such as lawn bowls.

In pin bowling, the goal is to knock over pins on a long playing surface known as a lane. Lanes have a wood or synthetic surface onto which protective lubricating oil is applied in different specified oil patterns that affect ball motion. A strike is achieved when all the pins are knocked down on the first roll, and a spare is achieved if all the pins are knocked over on a second roll. Common types of pin bowling include ten-pin, candlepin, duckpin, nine-pin, five-pin and kegel. The historical game skittles is the forerunner of modern pin bowling.

In target bowling, the aim is usually to get the ball as close to a mark  as possible. The surface in target bowling may be grass, gravel, or synthetic. Lawn bowls, bocce, carpet bowls, petanque, and boules may have both indoor and outdoor varieties.

Bowling is played by 120 million people in more than 90 countries (including 70 million in the United States alone), and is the subject of video games.
