The software release life cycle is the process of developing, testing, and distributing a software product (e.g., an operating system).It typically consists of several stages, such as pre-alpha, alpha, beta, and release candidate, before the final version, or "gold", is released to the public.
Alpha testing takes place at developers' sites and involves testing of the operational system by internal staff, before it is released to external customers. Beta testing takes place at customers' sites and involves testing by a group of customers who use the system at their own locations and provide feedback, before the system is released to ...
Alpha testing is simulated or actual operational testing by potential users/customers or an independent test team at the developers' site. Alpha testing is often employed for off-the-shelf software as a form of internal acceptance testing before the software goes to beta testing. [56]
For a Type I error, it is shown as α (alpha) and is known as the size of the test and is 1 minus the specificity of the test. This quantity is sometimes referred to as the confidence of the test, or the level of significance (LOS) of the test. For a Type II error, it is shown as β (beta) and is 1 minus the power or 1 minus the sensitivity of ...
Differences between alpha and beta. Though both greek letters, alpha and beta are quite different from each other. Alpha is a way to measure excess return, while beta is used to measure the ...

[10] As a consequence of this, in experimental science the null hypothesis is generally a statement that a particular treatment has no effect; in observational science, it is that there is no difference between the value of a particular measured variable, and that of an experimental prediction.

Software versioning is the process of assigning either unique version names or unique version numbers to unique states of computer software. Within a given version number category (e.g., major or minor), these numbers are generally assigned in increasing order and correspond to new developments in the software.
