A BETA Version is a pre-release version of a software program that is made available to the public for testing and feedback. It is usually the last stage of development before the official release of the software. The term 'BETA Version' comes from the Greek letter 'BETA', which is used in software development to indicate that the software is still in the testing phase. The term 'TEST' is an acronym for 'Testing Evaluation and Software Testing', which is the process of evaluating a software program to ensure that it meets the requirements of its intended use.
