Real-Time System

A Real Time system must satisfy the requirement of producing the desired result before a certain deadline. In a real time system timely production of result is as important as its execution capability.

Real-time systems provide immediate processing and also respond to user's commands immediately.
Some examples of real time system are given below:

• Airplane control and space vehicle operations
• Nuclear thermal power plant - Failure to respond in time to an error condition in a nuclear thermal power plant system could result in a melt-down.
• Automated factory - Failure to respond in time to an error condition in the assembly  line of an automated factory could result in the production of several defective products.
