In indirect communication between processes P and Q there is a mailbox to help communication between P and Q. A mailbox can be viewed abstractly as an object into which messages can be placed by processes and from which messages can be removed.

In indirect communication between processes P and Q, there is a mailbox to help communication between them.
Explanation:
1. Indirect Communication:
- Indirect communication refers to a method of communication where processes interact with each other through an intermediary entity instead of directly communicating with each other.
- This intermediary entity can be a mailbox, message queue, or any other communication mechanism that allows processes to exchange messages indirectly.
2. Process Communication:
- In a computer system, processes may need to communicate with each other to exchange information, coordinate activities, or share resources.
- Direct communication involves processes communicating with each other directly, whereas indirect communication involves processes communicating through an intermediary entity.
3. Mailbox:
- In the context of process communication, a mailbox is a data structure or a system resource used to exchange messages between processes.
- Each process can send messages to a mailbox and receive messages from a mailbox.
- The mailbox acts as a temporary storage location for messages, allowing processes to communicate asynchronously.
- When a process sends a message to a mailbox, it does not need to wait for the recipient process to receive the message immediately. The recipient process can retrieve the message from the mailbox at its convenience.
4. Role of Mailbox in Indirect Communication:
- In indirect communication between processes P and Q, a mailbox is used as a communication channel.
- Process P can send a message to the mailbox associated with process Q, and process Q can retrieve the message from the mailbox when it wants to.
- The mailbox ensures that the message is stored safely until the recipient process is ready to receive it.
- This allows processes to communicate asynchronously, meaning they can continue their execution without waiting for immediate response or synchronization.
Hence, in indirect communication between processes P and Q, there is a mailbox to help communication between them.
