Beta testing

Beta means a measure of the volatility, or systematic risk, of a security or a portfolio in comparison to the market as a whole.

Beta testing comes after alpha testing. Versions of the software, known as beta version, are released to a limited audience outside company. The software is released to groups of people so that further testing can ensure the product has few or no bugs. Sometimes, beta versions are made available to the open public to increase the feedback field to a maximal number of future users. But it is done in case of web sites. For example:- Gmail is still in it's beta version. Generally beta softwares are free to use by users.
