cam you tell me full form of XP in Windows XP

The XP in windows XP stands for eXperience........There is no special reason for calling it as such but it was a random decision.......I am sorry but I probably cannot say more about this........

The XP means "Extreme Programming", or XP, is a lightweight discipline of software development based on principles of simplicity, communication, feedback, and courage. XP is designed for use with small teams who need to develop software quickly in an environment of rapidly-changing requirements. XP was developed by Kent Beck, who wrote the original book on the subject, Extreme Programming Explained. Two new books will reach the market by October, Extreme Programming Installed, by Ron Jeffries, Ann Anderson, and Chet Hendrickson; and Planning Extreme Programming, by Kent Beck and Martin Fowler.
