The DECAlpha, also known as the Alpha AXP, is a 64-bit RISC microprocessor originally developed and fabricated by Digital Equipment Corp. (DEC), which used it in its own line of workstations and servers.
Alpha was born out of an earlier RISC project named PRISM, itself the final product of several earlier projects.
Ironically, in mid-2003, as the Alpha was about to be phased out, the fastest and second fastest computers in the U.S. were both implemented using Alpha processors (in the case of the former, a cluster of 4096 Alpha processors).
Alpha (Investment) - A coefficient measuring the risk-adjusted performance, considering the risk due to the specific security, rather than the overall market.
Humans and their nearest species-relatives, the chimpanzees, show deference to the alpha of the community by ritualized gestures such as bowing, allowing the alpha to walk first in a procession, or standing aside when the alpha challenges.
alpha version or alpha release - the first release of a computer program or other product, likely to be very unstable but useful for demonstrating internally and to select customers.
