What are the different IPC methods and how do they compare?

What are the different IPC methods and how do they compare?

There are several Inter-Process Communication (IPC) methods, including pipes, message queues, shared memory, and sockets. Each has its own advantages and use cases.

Can you explain how pipes work in IPC?

Pipes allow one process to send data to another process in a unidirectional flow. They are often used for communication between parent and child processes.

What about message queues? How do they differ from pipes?

Message queues allow multiple processes to communicate asynchronously by sending messages to a queue. Unlike pipes, they can handle messages from multiple senders and receivers.

Which IPC method is the fastest?

Shared memory is generally the fastest IPC method because it allows processes to access the same memory space directly, minimizing overhead.

Are there any security concerns with IPC methods?

Yes, IPC methods can have security concerns, such as unauthorized access to shared memory or message queues. It's important to implement proper access controls.
