UNIX, now in its 43rd year of existence, has proven itself a durable, reliable OS that has been widely adopted for a variety of purposes. Responsible in large measure for the integrity and popularity of UNIX is the Single UNIX Specification, a standard of The Open Group. This, according to Andrew Josey, Director of Standards at The Open Group, ensures compatibility across all platforms by providing a level of openness and enabling applications written to the standard to be easily moved across a wide range of platforms because the standard establishes a baseline of core functionality above which suppliers can innovate. The end result is that suppliers can focus on offering added value, while providing guarantees about the underlying durability of their products, he contends, adding that the open source movement has brought new vitality to the UNIX tradition.
