Computer software, or simply software, is that part of a computer system that consists of encoded information or computer instructions, in contrast to the physical hardware from which the system is built.

Software release life cycle

Stage of development

• Pre-alpha - phase to begin software testing 
• Beta - beta testing is reducing impacts to users, often incorporating usability testing
• Release candidate - A release candidate (RC) is a beta version with potential to be a final product, which is ready to release unless significant bugs emerge 

Once released, the software is generally known as a "stable release". The formal term often depends on the method of release: physical media, on-line release or a web application. 

• End-of-life - When software is no longer sold or supported, the product is said to have reached end-of-life, to be discontinued, retired, or obsolete, but user loyalty may continue its existence for some time, even long after its platform is obsolete—e.g., the Atari ST and Sinclair ZX Spectrum.
