Background process

Background process

A background process is a process that runs in the background of the system. That is to say the shell that executes the background process does not wait for it to finish or terminate as it does with foreground processes. The shell is free to execute more processes immediately after it initiates one to run in the background. Typical background processes that run on a system are event monitors or system loggers. The number of background processes that can run on a system are limited by your memory.

Characteristics

* Do not have a user interface.
* Typically are daemons and services.
* Run at a lower priority than foreground processes.

Unix Systems

In Unix based systems a process can be set to execute in the background by typing in a command and following it with an ampersand.
