Inter-Process Communication (IPC)

← Back to Processes and Threads

Mechanisms that allow processes to exchange data and coordinate their actions. Since processes have separate memory spaces, they need explicit IPC mechanisms to communicate.

Key Properties

• Pipes
• Sockets
• Shared Memory IPC
• Message Queues IPC
• Signals IPC

Related

• Process (IPC bridges the isolation between processes)
• Thread (threads share memory, reducing IPC need)
