Question

A message-passing model is _______ Faster than the shared memory model A network protocol, and does not apply to operating systems Only useful for small simple operating systems Easier to implement than a shared memory model for intercomputer communication Only useful for large complex operating systems

Answer 1

Answer:

Easier to implement than a shared memory model for inter-computer communication

Explanation:

Message passing model allows multiple processes to read and write data to the message queue without being connected to each other. Messages are stored on the queue until their recipient retrieves them. Message queues are quite useful for inter-process communication and are used by most operating systems.

Shared memory model has the memory that can be simultaneously accessed by multiple processes.

The message passing model is much easier to implement than the shared memory model.

But the message passing model has slower communication than the shared memory model because the connection setup takes time.
