Background operations/programs on servers

Background operations/programs on servers are programs that run in the background of the operating system. What is specific for a background process is that, once started, it runs simultaneously with other foreground processes. This means that, the shell executing the background operation does not wait for it to finish or terminate, as it does with foreground processes, but is free to start executing more operations along with the background one. Typical background processes are ircd, irc bot, bnc, and many others.
