Option 1 : 1 only

Explanation:

Real-time systems:

Real-time control and computing is the study of hardware and software systems that are subject to a “real-time constraint”.

A system is said to be a real-time system if there is total correctness of an operation. This depends upon not only the operation’s logical correctness but also the time in which it is performed and used.

The antilock brakes on a car are a simple example of a real-time computing system and the real-time constraint in the system is the short time in which the brakes must be released to prevent the wheel from locking.

Two types of real-time systems:

1. Hard real-time system: In this completion of an operation after its deadline is considered useless.

2. Soft real-time system: It tolerates such lateness and may respond with decreased.

Three concurrent processes X, Y, and Z execute three different code segments that access and update certain shared variables. Process X executes the P operation (i.e., wait) on semaphores a, b and c; process Y executes the P operation on semaphores b, c and d; process Z executes the P operation on semaphores c, d, and a before entering the respective code segments. After completing the execution of its code segment, each process invokes the V operation (i.e., signal) on its three semaphores. All semaphores are binary semaphores initialized to one. Which one of the following represents a deadlock-free order of invoking the P operations by the processes?

Option 2 : X: P(b)P(a)P(c) Y: P(b)P(c)P(d) Z: P(a)P(c)P(d)Answer: Option 2 Explanation:  Given Process X will perform down operation on a, b, c Process Y will perform down operation on b, c, d Process Z will perform down...
