What is the full form of IPC?
IPC: Interprocess Communication
IPC stands for Interprocess Communication. As the name suggests, it is a technology that enables multiple threads in one or more processes to communicate with each other. It allows the exchange of data between multiple threads of one or different processes or systems connected via a network.
This technology can also handle multiple requests simultaneously which means it can be used for sharing data between threads in a single or multiple processes. IPC is used by operating systems to share a large amount of data. However, it is not supported by a single process operating system like DOS and it can also affect performance.
In this technology, the requests are synchronized and implemented simultaneously. So, all the processes run smoothly and communicate with each other without affecting each other and cooperating with each other. Thus, it enables a programmer to coordinate the activities of different programs that are running simultaneously in an operating system. Using this technology, a program can handle multiple requests of users simultaneously.

Models of Interprocess communication:
Shared Memory Model:
In this model, the multiple processors can share the given memory simultaneously and thus can communicate with each other. For example, Windows operating systems and POSIX systems use this model.
Message Passing Model:
In this model, the multiple processors can write and read data to the queue of messages independently or without connecting to each other. The message stays on the queue until it is retrieved by its recipient. This model of IPC is widely used by most of the operating systems.
