What is a "Delta Force 2" CD key?

A "Delta Force 2" CD key is an alphanumeric code that software developers use to ensure that the game "Delta Force 2" was purchased legally. Sometimes called a "product key," "serial number" or "activation code," this type of key is used by a growing number of software developers.

Product keys are always unique to each specific item sold and can vary in length. These codes are typically entered before the actual software installation process begins. A mathematical algorithm manipulates the code in an attempt to match it with a code that is valid. It is important to keep the product key in a safe place, in case the software needs to be reinstalled at a future date. The key is essential to the operation of the game or program, and in most cases, the manufacturer will not replace it, if it is lost.
