First, prefaceClock is the basis of a timer, and any timer needs to work on a given clock. The kernel maintains a number of clock, the second chapter of this article describes the basic concept of clock and some statically defined POSIX clock.

IPC (inter-process communication, interprocess communication) can have three ways of sharing information (along with the file system, with the kernel, with shared memory). (Of course, although it is interprocess communication, it can also be
