The jobs command will list all processes associated with the current terminal and can be used to bring background processes into the foreground. [4] [11] When a login session ends, via explicit logout or network disconnection, all processes, including background processes, will by default be terminated, to prevent them from becoming orphan ...
The term was coined by the programmers at MIT's Project MAC.According to Fernando J. Corbató, who worked on Project MAC around 1963, his team was the first to use the term daemon, inspired by Maxwell's demon, an imaginary agent in physics and thermodynamics that helped to sort molecules, stating, "We fancifully began to use the word daemon to describe background processes that worked ...
Task Manager, previously known as Windows Task Manager, is a task manager, system monitor, and startup manager included with Microsoft Windows systems. It provides information about computer performance and running software, including names of running processes, CPU and GPU load, commit charge, I/O details, logged-in users, and Windows services.
Job control is a facility developed to make this possible, by allowing the user to start processes in the background, send already running processes into the background, bring background processes into the foreground, and suspend or terminate processes.
For example, one background process may be designed to accept incoming e-mails, sleeping most of the day but suddenly springing to life when an incoming e-mail arrives. An alternative background process could be designed to accept incoming requests for web pages hosted on the machine, waking up only when a request arrives to service it.
Daemonic applications are background processes that require no direct user interaction. Parasitic or Auxiliary applications are similar to transient applications in providing a limited, focused set of functionality and occupy a small space, but they are shown persistently and can be used for a long period of time.
Writing an email isn't so hard, but figuring out how to sign off can be a real challenge -- where one small word or punctuation mark could change the tone. Here is the perfect way to end an email ...
The process state is changed back to "waiting" when the process no longer needs to wait (in a blocked state). Once the process finishes execution, or is terminated by the operating system, it is no longer needed. The process is removed instantly or is moved to the "terminated" state. When removed, it just waits to be removed from main memory ...
