A system is said to be Real Time if it is required to complete its work & deliver
its services on time.
Real time systems are used in an environment where a large number of events
(generally external) must be accepted and processed in a short time.
Example – Flight Control System
All tasks in that system must execute on time.
Types of Real Time OS
Hard Real Time System
Failure to meet deadlines is fatal
Example: Flight Control System, Industrial control systems
Soft Real Time System
Late completion of jobs is undesirable but not fatal.
System performance degrades as more & more jobs miss deadlines
Example: Online Databases, Online Reservation System.
