alpha - Computer Definition
(1) See WolframAlpha.
(2) A family of RISC-based, 64-bit CPUs and computer systems from HP. Originally developed by Digital, which was acquired by Compaq and then HP, the first model introduced in early 1992 was the 150 MHz 21064-AA, considered equivalent to a Cray-1 on a single chip. Subsequent Alpha models continued to blaze the trails for high-speed microprocessors. Alpha-based servers (AlphaServers) run under Tru64 Unix and OpenVMS. In the mid-1990s, Windows NT was ported to the Alpha platform, but support was later dropped. Alpha Went to Intel In 2001, Compaq sold all Alpha intellectual property to Intel and announced it would switch its high-end servers to Intel's Itanium processors by 2004. HP acquired Compaq in 2002 and introduced enhanced AlphaServers. Orders were accepted for the new machines until April 2007, and support and service were promised until 2012.
alpha - Investment & Finance Definition
A measure of the risk-adjusted performance of an investment that factors in the individual risk of the security and not the overall market risk. A large alpha indicates that the stock or mutual fund has performed better than would be predicted given its beta, which is a measurement of an investment’s volatility.
