Q1Consider each of the following resource scenarios:

1. Recording audio though a computer's audio-in port.
2. Managing a pair of systems set up in a producer-consumer relationship.
3. Applying a blur filter to an image in an image editor.
4. Saving a large file (1+ GB) to a hard drive.

For each of these, select and justify the appropriate synchronization tool: mutex, semaphore, or none.

Q2

The second parameter for sem_init() is used to determine if the thread is to be shared between processes or not. What would be the benefit of enabling the shared parameter for initializing a semaphore? Explain.
