Difference between Alpha and Beta Testing

Alpha testing is final testing before the software is released to the general public. First, (and this is called the first phase of alpha testing), the software is tested by in-house developers. They use either debugger software, or hardware-assisted debuggers. The goal is to catch bugs quickly. Then, (and this is called second stage of alpha testing), the software is handed over to us, the software QA staff, for additional testing in an environment that is similar to the intended use.

Following alpha testing, "beta versions" of the software are released to a group of people, and limited public tests are performed, so that further testing can ensure the product has few bugs. Other times, beta versions are made available to the general public, in order to receive as much feedback as possible. The goal is to benefit the maximum number of future users.

Difference between Alpha and Beta Testing
In-house developers and software QA personnel perform alpha testing.
The public, a few select prospective customers, or the general public performs beta testing.

Hey, thanks for the feedback. Now, the page won't refresh automatically; it was just a trial and error code I missed to delete.

Keep on visiting.

hey one of the best application to illustrate the difference b/w alpha and beta testing is yahooessenger u use regularly.

when developed completely the software personnel test the application i.e.the messenger at their site .

after that beta versions are released for public use.this u can see if u download latest version of yahoomessenger with that u can find an option to give ur u r the public user
of the application conducting beta test and reporting the problems u face. likewise different users come out with different problems.
this is beta testing.
finally the developers modify the application with regard to the feedback from users.
then the final version is released for use

I feel that the main purpose of alpha testing is to make the software usable according to the expectations of the people who developed it. Whereas in beta testing the goal is to improve the software based on customer feedback so that when the commercial version is released, it matches the expectation of the customers, as far as possible.
