What is the primary benefit of nonblocking message passing?
What is the primary benefit of nonblocking message passing?
- It allows the sender to continue with other processing while waiting for the receiver to acknowledge the message.
- It allows for the implementation of a pipe data structure to exchange messages.
- It ensures that messages are never lost during transmission.
- It reduces the time that processes spend waiting for messages to be received. (correct)
What is a common implementation of message passing in distributed systems?
What is a common implementation of message passing in distributed systems?
- A definition of a process that ensures reliable message delivery.
- A region of memory protected by the operating system that serves as a buffer for exchanging data. (correct)
- A stack data structure that stores the sequence numbers of messages.
- A text region in memory that stores the content of the messages being exchanged.
What mechanism is used in distributed systems to ensure that transmitted messages are not lost?
What mechanism is used in distributed systems to ensure that transmitted messages are not lost?
- Acknowledgement protocols that confirm the proper receipt of transmissions.
- Timeout mechanisms that retransmit messages if acknowledgements are not received.
- Sequence numbers that allow the receiver to resequence out-of-sequence messages.
- All of the above. (correct)
