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.
Yeyiphi imihla ebekiweyo ye-RTOS ekhululekileyo?
Umzekelo, ukuba umsebenzi KUFUNEKA wenze umsebenzi wawo kwisekondi enye, ke umhla obekiweyo ngumhla wokugqibela. Kwelinye icala, ukuba umsebenzi KUFUNEKA wenze umsebenzi wawo malunga nomzuzwana omnye okanye njalo, ngoko ke ixesha elibekiweyo liyaphumla. Xa imihla ebekiweyo iphelele, inkqubo yexesha lokwenyani ibizwa ngokuba yinkqubo yexesha lokwenyani.

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.
