A hard real-time system (also known as an immediate real-time system) is hardware or software that must operate within the confines of a stringent deadline. The application may be considered to have failed if it does not complete its function within the allotted time span.
What is hard and soft real time operating system?
HARD REAL TIME SYSTEM. SOFT REAL TIME SYSTEM. In hard real time system, the size of data file is small or medium. In soft real time system, the size of data file is large.

What is the difference between hard real time and soft real time?
The difference between hard and soft real time system is that, a hard-real time system is a system in which a single failure to meet the deadline may lead to a complete system failure while a soft real time system is a system in which one or more failures to meet the deadline is not considered as complete system …

Is a example of hard real time embedded system?
Examples for Hard Real Time Systems are Flight Control Systems, Missile Guidance Systems, Weapons Defense System, etc. On the other hand, Soft Real Time Systems have some relaxation in meeting the deadlines i.e. the degree of tolerance is non-zero.
Which RTOS deadlines are relaxed?
For example, if a task MUST perform its function within one second, then the deadline is an absolute deadline. On the other hand, if the task SHOULD perform its function in about one second or so, then the deadline is relaxed. When the deadlines are absolute, the real-time system is called a hard real-time system.

What are the requirements of hard real time and soft real time system?
A hard real-time system must remain synchronous with the state of the environment in all cases. On the otherhand soft real-time systems will slow down their response time if the load is very high. Hard real-time systems are often safety critical. Hard real-time systems have small data files and real-time databases.
