Inter Process Communication in Operating System

Inter-Process Communication or IPC refers to the methods and techniques that allow processes (programs or tasks) to communicate with each other within a computer system. This is typically done through shared memory, pipes, sockets, and message queues. These mechanisms allow processes to share data and synchronize their actions, and are important part of many operating systems. Different operating systems provide different IPC mechanisms, and the choice of mechanism depends on the specific requirements of the application and the system in used application.

Why is IPC required?

IPC is required because it allows multiple processes to share resources and communicate with each other.

Without IPC, each process would have to be a self-contained program that cannot interact with other processes. This would make it difficult to create complex, multi-faceted applications and would also limit the ability of different processes to share information and work together.

IPC also allows for better resource utilization by enabling multiple processes to work on different parts of a task simultaneously. This can lead to increased performance and efficiency.

Additionally, IPC allows for the creation of client-server applications, where one process acts as a server that provides services to other processes, called clients. This can be used to create distributed systems, where multiple processes running on different machines communicate with each other to accomplish a common goal.

IPC is also used to handle communication between different user spaces, and between the user space and kernel space.

In short, IPC is a fundamental building block for implementing modern, concurrent and distributed systems.

Approaches for Inter Process Communication

There are several approaches used for inter-process communication (IPC) in operating systems. Some of them are as follows:

  • Shared memory: This approach involves creating a shared memory segment that can be accessed by multiple processes. This allows processes to share data without the need for explicit communication.
  • Pipes: A pipe is a unidirectional communication channel that allows processes to send and receive data. This can be useful for simple communication between related processes.
  • Sockets: Sockets are a more flexible form of IPC that allow for both local and remote communication. They are commonly used for networking applications and can support different transport protocols such as TCP and UDP.
  • Message queues: This approach involves using a message queue as a buffer for messages between processes. This allows processes to send and receive messages without the need for direct communication.
  • Semaphores: A semaphore is a synchronization object that controls access to shared resources. It can be used to coordinate the actions of multiple processes and prevent race conditions.
  • Signals: Signals are a simple form of IPC that allows processes to send notifications to each other. They are typically used for simple communication between related processes or for handling exceptions or errors.

Synchronization in Inter Process Communication

Synchronization is an important aspect of inter-process communication (IPC) as it ensures that the processes involved in the communication are in a consistent state and their data is being accessed and modified in a controlled and predictable manner.

There are several ways to synchronize inter process communication. Some of them are as follows:

  • Semaphores: Semaphores are synchronization tools that can be used to coordinate access to shared resources between multiple processes. They work by providing a mechanism for processes to request and release access to a resource, and for other processes to wait until the resource is available.
  • Locks: Locks are a way to ensure that only one process can access a shared resource at a time. They can be implemented using semaphores, mutexes, or other synchronization primitives.
  • Monitors: Monitors are synchronization tools that provide a way for processes to wait for specific conditions to be met before proceeding. A monitor is a combination of a semaphore and a set of procedures that can be called by processes to wait for and signal the occurrence of specific events.
  • Barriers: Barriers are synchronization point for multiple processes that wait until all of them reach the barrier point before proceeding.
  • Condition Variables: Condition variables are used to synchronize access to shared resources by allowing processes to wait for a certain condition to be met before proceeding.
  • Atomic Operations: Atomic operations are operations that can be executed by a single process without interruption by other processes. This can be achieved by using atomic operations provided by the operating system or programming language.
