(From Wikipedia, the free Encyclopedia)
In computing, an accelerator is an additional unit of hardware to perform some function faster than is possible in software running on the normal CPU. Examples include graphics accelerators and floating-point accelerators. The term is outdated and has been replaced with more descriptive terms like video card or graphics card. In computing, the term accelerator is used for the shortcut key which produces the same effect as a pull-down menu entry, for example using CTRL-S instead of the menu "File" and the contained entry "Save".This article was originally based on material from FOLDOC, used with permission.

 | This is Gordon Isaacs, the first patient treated with the linear accelerator (radiation therapy) for retinoblastoma in 1957. Gordon's right eye was removed January 11, 1957 because the cancer had spread. His left eye, however, had only a localized tumor that prompted Henry Kaplan to try to treat it with the electron beam. Gordon is now living in the east bay, and his vision in the left eye is normal. Credit: Unknown photographer/artist. |  | Dr. Henry Kaplan, in the 1950's, with an early model of the Linear Accelerator developed to treat cancer. For this picture the protective hood was removed, revealing the electronic insides of the six-million volt machine, used for radiation treatment. Credit: Unknown photographer/artist. |

Business | Equipment obsolescence regarding linear accelerator would indicate that at least each Argentine province would need to acquire new equipment. (references) | |
Economic History | Australia | In addition, there is a high degree of interest on the part of Australian state governments and commercial entities in Australia's biotechnology sector, which generated A$1 billion (US$520 million) in revenue in 2000. A positive development for the sector was the announcement by the Victorian State Government (in June 2001) of the decision to build a synchrotron (an electron accelerator, which acts as an immensely powerful microscope), likely to attract research and development activities to the state.
