XPC

XPC (Inter-Process Communication) is a secure way for different parts of a computer system or applications to communicate with each other efficiently. It enables separate programs or components to exchange data or request services without sharing the same memory space, which enhances stability and security. Think of it like a well-organized messaging system that ensures information flows smoothly between different processes, allowing them to work together without interfering with each other. XPC is commonly used in operating systems like macOS and iOS to keep apps responsive and secure.
