What exactly is a signal? Can it carry some information like an electromagnetic wave signal?

write picture description here

Well, let's take a look at how the iceberg in the Linux kernel looks like, how to implement its own signal mechanism, and how to optimize the signal in the kernel

1: The parent process exits and sends a signal to the child process
