Inter-process communication modes and characteristics

1. Piping

Nameless pipes are a method of communication that is used only for half-duplex between parent-child processes. A well-known pipeline is the ability to communicate between unrelated processes.

2. Signal Volume

Used to control multi-process or multi-threaded access to shared resources, is a multi-process and multi-threaded synchronization between the means.

3. Signal

Used to notify the receiving process that an event has occurred.

4. Shared Memory

Shared memory is the memory that maps a section of other processes that can be accessed by multiple processes. It is the fastest way to communicate between processes, usually with the signal volume and so on to achieve synchronization and communication between processes.

5. Sockets

Used for communication between different processes.
