The AIX® and UNIX® zone of developerWorks contains articles, tutorials, and tips to help developers with AIX and UNIX application development and system administration. For users trying to find their way in a new topic, all of that information can be overwhelming. This page provides an overview for readers who would like to learn about AIX and UNIX, but don't know where to start.
Invented at AT&T Bell Labs in 1969, UNIX (the name is a play on the earlier Multiplexed Information and Computing Service (Multics) operating system) is a robust, flexible, and developer-friendly computing environment. Written originally for the Digital Equipment Corporation (DEC) family of PDP microcomputers, this most popular of multi-user, general-purpose operating systems has taken over roles in all areas of computing -- even those once held by mainframes.
Introduced in January of 1986, AIX is the IBM implementation of the UNIX operating system. The newest version of AIX, Version 7, is binary compatible with previous versions of the AIX, including AIX 6, AIX 5L and even earlier versions of AIX. This means applications that ran on earlier versions will continue to run on AIX 7. AIX 7 is an open-standards-based UNIX OS that is designed to comply with the Open Group's Single UNIX Specification Version 4.
AIX is supported by a broad range of independent software vendors (ISVs) that provide application solutions to meet business needs. IBM also offers:
The IBM learning services site offers classes that cover everything from the basics to development to highly specialized skills, as well as certification. You can also get articles and tips on IBM products from IBM developer solutions. The greater IBM website also offers many other resources, and IBM developerWorks offers articles, tutorials, and resources on AIX and UNIX, as well as several other open or free technologies including XML, wireless, web services, Java technology, and grid computing.
In addition to steadfast stalwarts like Fortran and C/C++, many scripting and other computer languages are at home on AIX and UNIX.
