What is a Beta and Why is it Used?
A Beta version is originally used to refer to software applications that are close to completion. Beta software is still under active development, debugging, and revisions. Beta software typically doesn’t have all features (even sometimes critical ones) implemented fully or at all.
In the modern terminology, one can have a beta. In this usage, the beta represents a time span during which public users are selectively invited to try out unfinished or untested software as it under goes its final development stages.
