The alpha phase of the release life cycle is the first phase to begin software testing. Alpha software can be unstable and could cause crashes or data loss. The exception to this is when the alpha is available publicly, in which developers normally push for stability so that their testers can test properly. (Source WikiPedia)

Alpha (uppercase Α, lowercase α; Greek: Άλφα Álpha) is the first letter of the Greek alphabet. In the system of Greek numerals it has a value of 1. It was derived from the Phoenician letter aleph . Letters that arose from alpha include the Latin A and the Cyrillic letter А.
In English, the noun "alpha" is used as a synonym for "beginning", or "first" (in a series), reflecting its Greek roots.
