Due to hardware limits, background processes on mobile operating systems are often restricted to certain tasks or consumption levels. On Android, CPU use for background processes may be bounded at 5–10%. [13] Applications on Apple's iOS are limited to a subset of functions while running in the background. [3]
A job running in the foreground can be stopped by typing the suspend character . This sends the "terminal stop" signal (SIGTSTP) to the process group. By default, SIGTSTP causes processes receiving it to stop, and control is returned to the shell. However, a process can register a signal handler for or ignore SIGTSTP.
The SIGSTOP signal instructs the operating system to stop a process for later resumption. SIGSYS The SIGSYS signal is sent to a process when it passes a bad argument to a system call. In practice, this kind of signal is rarely encountered since applications rely on libraries (e.g. libc) to make the call for them.

A terminate-and-stay-resident program (commonly TSR) is a computer program running under DOS that uses a system call to return control to DOS as though it has finished, but remains in computer memory so it can be reactivated later. [1] This technique partially overcame DOS's limitation of executing only one program, or task, at a time.

It is the Services and Controller app, services.exe, that launches all the services and manages their actions, such as start, end, etc. [2] Windows services can be configured to start when the operating system is started and run in the background as long as Windows is running. Alternatively, they can be started manually or by an event.
