Beta
A program that has not yet been introduced to the public but is being released to a select few to test, examine and report problems they may experience so that those errors can be fixed before the final release. This type of product should never be purchased.
Often there are two types of beta testing, open beta and closed beta. Open beta refers to beta testing that is open to any user. Closed beta refers to beta testing that is only available to a select few individuals or to company individuals.
