Background processA background process is a computer process that runs behind the scenes (i.e., in the background) and without user intervention. Typical tasks for these processes include logging, system monitoring, scheduling, and user notification. On a Windows system, a background process is either a computer program that does not create a user interface, or a Windows service. The former are started just as any other program is started, e.g., via Start menu.Windows serviceIn Windows NT operating systems, a Windows service is a computer program that operates in the background. It is similar in concept to a Unix daemon. A Windows service must conform to the interface rules and protocols of the Service Control Manager, the component responsible for managing Windows services.Process groupIn a POSIX-conformant operating system, a process group denotes a collection of one or more processes. Among other things, a process group is used to control the distribution of a signal; when a signal is directed to a process group, the signal is delivered to each process that is a member of the group. Similarly, a session denotes a collection of one or more process groups.
Super-serverA super-server, sometimes called a service dispatcher, is a type of daemon run generally on Unix-like systems. UsageA super-server starts other servers when needed, normally with access to them checked by a TCP wrapper. It uses very few resources when in idle state. This can be ideal for workstations used for local web development, client/server development or low-traffic daemons with occasional usage (such as ident and SSH).
Secure ShellThe Secure Shell Protocol (SSH Protocol) is a cryptographicnetwork protocol for operating network services securely over an unsecured network. Its most notable applications are remote login and command-line execution.
Tty (Unix)In computing, tty is a command in Unix and Unix-likeoperating systems to print the file name of the terminal connected to standard input. tty stands for "teletypewriter". UsageThe tty command is commonly used to check if the output medium is a terminal. The command prints the file name of the terminal connected to standard input.
Computer programInstructions a computer can executeSource code for a computer program written in the JavaScript language. It demonstrates the appendChild() method. The method adds a new child node to an existing parent node. It is commonly used to dynamically modify the structure of an HTML document.A computer program is a sequence or set of instructions in a programming language for a computer to execute.
UnixUnix ( , YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, the development of which started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
Croncron is a time-based job scheduler. A scheduled job is known as a cron job. Although typically used to automate system maintenance and administration it can be used to automate any task. cron is most suitable for scheduling repetitive tasks, as scheduling a one-time task can be accomplished via at. The daemon name originates from Chronos, the Greek word for time. cron is generally available on Unix-like operating systems.
BootingIn computing, booting is the process of starting a computer as initiated via hardware such as a physical button on the computer or by a software command. After it is switched on, a computer's central processing unit (CPU) has no software in its main memory, so some process must load software into memory before it can be executed. This may be done by hardware or firmware in the CPU, or by a separate processor in the computer system.
ComputingComputing is any goal-oriented activity that requires, benefits from, or creates computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both hardware and software. Computing encompasses scientific, engineering, mathematical, technological, and social aspects.
SyslogIn computing, syslog () is a standard for message logging. It allows separation of the software that generates messages, the system that stores them, and the software that reports and analyzes them. Each message is labeled with a facility code, indicating the type of system generating the message, and is assigned a severity level.
