Definition Killer App: Killer Application
Explanation: Killer application, also known as killer app, is a computer program that is so useful or desirable that it proves the value of some underlying technology, such as a gaming console, operating system, or piece of computer hardware or deploying an entire network. Killer applications are very rare. One of examples was VisiCalc, the first spreadsheet to run on a personal computer because it provided an unique tool for people to manipulate numbers easily without the need for programming skills. Another example of the killer app is Voice over IP (VOIP), which brough telephony service opportunities using packet network.
