What is the fastest IPC method in Linux?

Shared memory is the fastest form of interprocess communication. The main advantage of shared memory is that the copying of message data is eliminated. The usual mechanism for synchronizing shared memory access is semaphores.

What are Linux IPC mechanisms?

Linux supports three types of interprocess communication mechanisms which first appeared in Unix System V (1983). These are message queues, semaphores and shared memory. These System V IPC mechanisms all share common authentication methods.

Is FIFO an IPC mechanism?

A pipe is a mechanism for interprocess communication; data written to the pipe by one process can be read by another process. The data is handled in a first-in, first-out (FIFO) order. The pipe has no name; it is created for one use and both ends must be inherited from the single process which created the pipe.

What is interprocess communication ( IPC ) in Linux?

This is the first article in a series about interprocess communication (IPC) in Linux. The series uses code examples in C to clarify the following IPC mechanisms: This article reviews some core concepts before moving on to the first two of these mechanisms: shared files and shared memory.

When do you need to use IPC in system programming?

In System Programming, almost all the time you have to use IPC to carry out data exchange between processes, therefore students graduating in computer science and looking to seek an opportunity in MNCs as a developer should have IPC concepts at his/her finger tips. It shall be advantageous if you know a little of C and OS.

Is it possible to teach IPC in Linux?

Though we use Linux to teach the IPC techniques, conceptually, IPC of linux is not very different from other OS platforms such as windows, iOS etc. So, if you are a programmer for other platforms, this course still holds a great value for you. This course has auto system-generated subtitles which may not be perfect.

Which is the best language for learning IPC?

Learning IPC using C helps you understand what is going on behind the scenes. C language really exposes the low level details about how system actually works. In System programming, C is the only language to be used and there is not even a remote substitute of this language when it comes to System programming.
