c) using pipes
d) all of the mentioned

Answer 1

The circular wait condition, which is a potential cause for deadlocks, can be prevented by defining a linear ordering of resource types.

Step-by-step explanation:

The circular wait condition can be prevented by defining a linear ordering of resource types. This strategy is used in operating systems to avoid deadlocks, a state where two or more processes are unable to proceed because each is waiting for the other to release resources. By predefining a global order in which all resources must be requested, the system can ensure that circular wait, one of the four necessary conditions for a deadlock, cannot occur. For example, if we have resource types R1, R2, and R3, we might assign an order where R1 < R2 < R3. A process would only be allowed to request resources in this order, thus making a circular wait among processes impossible.
