+====== Daemon ======
+In computing terms a //daemon// is a server process which is resident in memory but inactive until it is woken up by an operating system event. The server-side process of most network applications is implemented as a //daemon//: it initializes itself as necessary in order to be able to perform its service then establishes a [[server_socket|socket]], usually at a well known [[port number]], before becoming inactive. When a client attempts to connect to the server socket, the //daemon// process wakes up, services the request (often by spawning a new server process), before returning to its quiescent waiting mode.
+In the [[unix|Unix operating system]] //daemons// are often identifiable by ending in the letter //d//, for example [[httpd]], [[sshd]], [[ftpd]] and [[telnetd]]. Daemon processes are usually started by the operating system when it boots up. Windows also has daemons, which are called //sevices//, but windows doesn't necessarily use a naming convention to identify them.
