WPA

1. Windows Product Activation. An anti-piracy measure from Microsoft where each copy of software can only be used for a limited time before it stops working unless the product is activated - either by phone or across the internet. Activation involves checking that the product key has not already been registered and ties the product to the machine on which it is being registered. The software can then not be activated on anther PC.

2. Wi-Fi Protected Access. An encryption standard used to protect data on many wireless networks. WPA is more secure and generally regarded as the successor to WEP.
