Operating System - Inter-process communication

Inter-process communication (IPC) refers to the mechanisms and techniques that allow different processes or applications running on a computer to exchange data and synchronize their actions. It's crucial for enabling collaboration and interaction between processes, which would otherwise operate in isolation. IPC allows processes to share resources, coordinate operations, and achieve complex tasks by working together. 

Increased Efficiency:By allowing multiple processes to work concurrently, IPC can significantly improve the overall performance of a system. 

Modularity:IPC allows for the development of modular software, where different processes can be developed and maintained independently, making the system easier to manage and update. 

Resource Sharing:IPC enables processes to share resources like files, databases, or hardware devices, optimizing resource utilization. 

The two fundamental models of Inter Process Communication are:

Shared Memory:Processes share a common memory region, allowing them to access and modify the same data directly.

Message Passing:Processes communicate by explicitly sending messages to each other. This involves copying data from the sender's address space to the receiver's address space
