What are the two fundamental models of inter process communication?
There are two fundamental models of interprocess communication:
- Shared Memory. A region of memory that is shared by cooperating processes is established.
- Message Passing. Communication takes place by means of messages exchanged between the cooperating processes.
What are the types of inter process communication?
Methods in Interprocess Communication
- Pipes (Same Process) – This allows flow of data in one direction only.
- Names Pipes (Different Processes) – This is a pipe with a specific name it can be used in processes that don’t have a shared common process origin.
- Message Queuing –
- Semaphores –
- Shared memory –
- Sockets –
How process communicate with each other explain in detail?
Here, are few important methods for interprocess communication:
- Pipes. Pipe is widely used for communication between two related processes.
- Message Passing: It is a mechanism for a process to communicate and synchronize.
- Message Queues:
- Direct Communication:
- Indirect Communication:
- Shared Memory:
- FIFO:
Shared memory system is faster interprocess communication model. Shared memory allows cooperating processes to access the same pieces of data concurrently. Using shared memory, also speed ups the computation power of the system as the long task can be divided into smaller sub-tasks and can be executed in parallel.
What is meant by Inter Process Communication explain the two fundamental models of inter process communication?
Interprocess communication is the mechanism provided by the operating system that allows processes to communicate with each other. This communication could involve a process letting another process know that some event has occurred or transferring of data from one process to another.
What are the two steps of a process execution?
Answer is “I/O Burst, CPU Burst”

How two processes running on machine can communicate?
There are two main ways to communicate between processes. Those are shared memory and message passing. Shared memory using a shared portion of memory and message passing doing via direct or indirect links.
How can two processes on different systems communicate with each other?
There are two different ways for processes to communicate : they can share a resource ( such as an area of memory ) which each can alter and inspect, or they can communicate by exchanging messages. In either case, the operating system must be involved.
What are the benefits of inter process communication?
Advantages of using CICS Inter Process Communication
- Use of shared memory for communication, limits Remote Procedure Call communication on the local machine.
- Only users with access to the shared memory can view the calls.
- Use OS provided authentication in absence of DCE security.
Why is Inter Process Communication Important?
Inter process communication (IPC) is a mechanism which allows processes to communicate with each other and synchronize their actions. IPC is very important to the design process for operating system kernels that desire to be kept small, therefore reduce the number of functionalities provided by the kernel.
