    1. In shared memory model, memory is shared by cooperating processes, which can exchange information by reading and writing data but in message passing communication takes place by means of messages exchanged between the cooperating processes.
    2. Shared memory helps run processes concurrently but message passing cannot.
    3. Message passing facility has two operations: send (message) and receive (message). ...

    What is message passing model and shared memory model?
    Message passing model and shared memory model are models of interprocess communication. Details about these are given as follows: 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.

    Is shared memory faster than message passing?
    Shared memory is faster than message passing, as message-passing systems are typically implemented using system calls and thus require the more time-consuming task of kernel intervention. on point 2), I do think concurrency can be achieved in an message-passing model, by broadcasting messages to other workers that can start working simultaneously.

    What are the advantages and disadvantages of shared memory?
    In the above diagram, the shared memory can be accessed by Process 1 and Process 2. An advantage of shared memory model is that memory communication is faster as compared to the message passing model on the same machine. However, shared memory model may create problems such as synchronization and memory protection that need to be addressed.

    What is a shared memory segment?
    This memory region is present in the address space of the process which creates the shared memory segment.The processes who want to communicate with this process should attach this memory segment into their address space. 2. Message Passing Model : In this model, the processes communicate with each other by exchanging messages.
