Question:
Which of the following enables indirect communication in IPC?
Which of the following enables indirect communication in IPC?
Show Hint
A mailbox in IPC enables indirect communication, allowing processes to send and receive messages asynchronously without direct interaction.
Updated On: Feb 6, 2025
- Pipe
- Shared memory
- Link
- Mailbox
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding Interprocess Communication (IPC)
- IPC mechanisms allow processes to communicate and share data.
- Communication can be direct (process-to-process) or indirect (via an intermediary entity like a mailbox or message queue).
Step 2: Indirect Communication in IPC
- In indirect communication, processes do not communicate directly.
- Instead, they send and receive messages via an intermediary such as a mailbox.
Step 3: Evaluating the Options
- (A) Incorrect: Pipes enable direct communication between related processes.
- (B) Incorrect: Shared memory allows direct access to a common memory space.
- (C) Incorrect: A link establishes direct communication between processes.
- (D) Correct: Mailboxes enable indirect communication by storing messages that can be retrieved asynchronously.

- Consider the following sets of processes, with the length of CPU burst time given in milliseconds: \(\begin{array}{|c|c|c|} \hline \text{Process} & \text{Burst Time (ms)} & \text{Priority} \\ \hline P_1 & 8 & 4 \\ P_2 & 6 & 1 \\ P_3 & 1 & 2 \\ P_4 & 9 & 2 \\ P_5 & 3 & 3 \\ \hline \end{array}\)
The processes are assumed to have arrived in the order \( P_1, P_2, P_3, P_4, P_5 \) all at time 0.

The processes are assumed to have arrived in order P1, P2, P3, P4, P5 all at time 0. What is the waiting time of process P4 for Shortest Job First (SJF), non-preemptive priority scheduling, and Round Robin (Quantum=1) scheduling algorithms respectively? - Consider the following statements and choose the correct one:
(A) Job schedulers select processes from the pool and load them into memory for execution.
(B) Short term scheduler selects among the processes that are ready to execute and allocates the CPU to one of them.
(C) Medium term scheduler increases the degree of multiprogramming.
