Some people pride themselves on keeping their computers up and running for long periods of time, and now we have kernel hotfixes that only require a machine shutdown if a hardware failure occurs. What I think is more practical is to save power by reducing wear and tear on moving parts and shutting down the machine when it is not needed.

For example, reading and writing files: open/read/write will switch from user mode to kernel mode; for example, applying for memory: C language: malloc/java language new. Every object needs to apply for memory space. ; Including select/poll/epoll, they are all system calls; the switching method is to switch from user mode to kernel mode.
