A crash (or system crash) in computing is when a computer program (such as a software application or an operating system) stops functioning properly. Often it will exit the affected program after encountering this type of error. The program responsible may appear to freeze until a crash reporting service reports the crash and potentially any details relating to it. If the program is a critical part of the operating system, the entire computer may crash, often resulting in a kernel panic or fatal system error, or in rare cases, an unstable network.

Many crashes are the result of single or multiple machine instructions running incorrectly. Typical causes are when the program counter is set to an incorrect address or a buffer overflow overwrites a portion of the affected program code due to an earlier bug. In either case, it is common for the CPU to attempt to access data or random memory values. Since all data values are possible to select but not always valid for the request, this often results in an illegal instruction exception. By chance, such data or random values could be valid (though unplanned) instructions. The original program problem (software bug) is considered as what "caused" the crash, but the actual fault may be an illegal instruction. The process of debugging such crashes is connecting the actual cause of the crash with the code that started the chain of events. This is often far from obvious; the original bug is usually perfectly valid code presented to the processor.

Crash (b. John Matos, Bronx, New York, October 11, 1961) is a graffiti artist. As early as 13, John Matos was spray painting New York City trains, the full image art as opposed to simpler tagging soon transferred to silk screened canvas. He was first noticed through his murals on subway cars and dilapidated buildings, he is now regarded as a pioneer of the Graffiti art movement. His work is said to convey a "visual link between street life and established society". In 1980, Crash curated the now iconic exhibition:"Graffiti Art Success for America" at Fashion MODA, launching the graffiti movement that has remained very active through today. By the 1980s Matos had exhibits across the United States and abroad. Galerie Yaki Kornblit was the first instrumental gallery in Amsterdam that help launch his career in Europe. In 1981 Crash, along with 10 other artists were chosen by The Public Art Fund to design animated imagery for The Spectacolor Billboard in Times Square. He was given his first gallery showing by Sidney Janis at the Sidney Janis Gallery in 1983. Chase Manhattan, N.A., as well as CITIBANK, N.A., and other collections came calling. In 1984, Crash along with Keith Haring painted mural installations for the 5/5 Figuration Libre France/USA at the Musee d'art Moderne de la Villa de Paris. In 1988 he sprayed Notes in the Wind measuring 178 x 178 centimetres to be exhibited and eventually to be owned by the Peter Stuyvesant Foundation in Zevenaar, Netherlands. In 1995, Crash was commissioned by British American Tobacco to create a commission for Lucky Strike brand cigarette, joining fellow artist Keith Haring, to create a special work for this company and their collection.
