Learn POSIX from best Institutes in Tirupur. POSIX is an acronym which stands for Portable Operating System Interface. It is a set of standard operating system interfaces based on the Unix operating system. The need for standardization arose because enterprises using computers wanted to be able to develop programs that could be moved among different manufacturers computer systems without having to be recoded. Unix was selected as the basis for a standard system interface partly because it was "manufacturer-neutral." However, several major versions of Unix existed so there was a need to develop a common denominator system. Informally, each standard in the POSIX set is defined by a decimal following the POSIX. Thus, POSIX.1 is the standard for an application program interface in the C language. POSIX.2 is the standard shell and utility interface. These are the main two interfaces, but additional interfaces, such as POSIX.4 for thread management, have been developed or are being developed. The POSIX interfaces were developed under the auspices of the Institute of Electrical and Electronics Engineers (IEEE).

POSIX.1 and POSIX.2 interfaces are included in a somewhat larger interface known as the X/Open Programming Guide. The Open Group, an industry standards group, owns the UNIX trademark and can thus "brand" operating systems that conform to the interface as "UNIX" systems. IBMs OS/390 is an example of an operating system that includes a branded UNIX interface. Short for "Portable Operating System Interface for uni-X", POSIX is a set of standards codified by the IEEE and issued by ANSI and ISO. The goal of POSIX is to ease the task of cross-platform software development by establishing a set of guidelines for operating system vendors to follow. Ideally, a developer should have to write a program only once to run on all POSIX-compliant systems. Most modern commercial Unix implementations and many free ones are POSIX compliant. There are actually several different POSIX releases, but the most important are POSIX.1 and POSIX.2, which define system calls and command-line interface, respectively. There are other standardization efforts in the Unix world. The most prominent are the Open Group XPG guidelines and the System V Interface Definitions (SVID). POSIX, however, is the only major standard endorsed by the vendor-neutral standards organizations.. The below are list of institutes offeres best posix training in Tirupur.
