What methods of inter-process communication (IPC) do you know?

There are several main methods of inter-process communication (IPC):

• Pipes — allow data transfer between processes through byte streams. They can be named or unnamed.
• Sockets — network interfaces that can be used for data exchange between processes both on the same machine and over a network.
• Shared Memory — allocating a memory area accessible by multiple processes for fast data transfer.
• Semaphores — synchronization mechanisms that help coordinate access to shared resources.
• Message Queues — message queues that enable processes to exchange structured messages.
• Signals — asynchronous notifications about events that processes can send to each other.
• Files and Databases — processes can exchange information through reading and writing to files or databases.

The choice of method depends on requirements for speed, data volume, synchronization complexity, and application architecture.
