An Inter Process Communication (IPC) describes the fact that two or more processes exchange information.
IPC is used not just for communication between processes on the same system, but also on different systems.
- shared memory - shared variable. If two applications/process are installed on the same machine, they can improve performance by using a shared memory segment for inter-process communication (IPC). Using a shared memory segment as communication allows for the best performance, but consumes more memory.
- remote procedure calls (RPC) - Call of functions
Most operating systems support Inter Process Communication (IPC) resources, such as:
- sockets. A socket an endpoint of an inter-process communication flow across a computer network.
