xoaqwepo: backgrounds for computers

##title##

On a Unix system, a background process or job can be further identified as one whose group ID differs from its terminal group ID. This type of process is unable to receive keyboard signals from and typically will not send output to its parent terminal. This more technical definition does not distinguish between whether or not the process can receive user intervention.

Although background processes are typically used for purposes requiring few resources, any process can be run in the background, and even though the process is running in the background, where it can't be seen, it behaves like any other process.

A daemon is a type of background process designed to run continually in the background, waiting for event(s) to occur or condition(s) to be met. These processes typically use minimal system resources and perform tasks which require little to no input from the user. When launched with the daemon function, daemons are disassociated from their parent terminal.
