What is a soft real-time operating system?
a) An operating system where critical tasks are given priority but delays are acceptable
b) An operating system where delays are not allowed for any tasks
c) An operating system that manages file systems
d) An operating system that does not support real-time tasks
Answer:
a) An operating system where critical tasks are given priority but delays are acceptable
Explanation:
A soft real-time operating system is one where critical tasks are given priority over non-critical tasks, but occasional delays are acceptable. These systems ensure that critical tasks are executed as quickly as possible, but they do not guarantee strict deadlines for task completion.
Soft real-time systems are used in environments where timing is important but not absolutely critical, such as in multimedia applications, where small delays might be tolerable without significantly affecting performance.
In contrast, hard real-time systems require that critical tasks meet strict deadlines without fail, making them suitable for applications like industrial control systems or medical devices.
