Many computer protocols, such as telnet, include a NOP command that a client can issue to request a response from the server without requesting any other actions. Such a command can be used to ensure the connection is still alive or that the server is responsive. A NOOP command is part of the following protocols (this is a partial list): telnet ...
In computer science, futures, promises, delays, and deferreds are constructs used for synchronizing program execution in some concurrent programming languages.Each is an object that acts as a proxy for a result that is initially unknown, usually because the computation of its value is not yet complete.
In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.
A sleep command is also part of ASCII's MSX-DOS2 Tools for MSX-DOS version 2. [8] In PowerShell, sleep is a predefined command alias for the Start-Sleep cmdlet which serves the same purpose. [9] Microsoft also provides a sleep resource kit tool for Windows which can be used in batch files or the command prompt to pause the execution and wait ...
watch is a command-line tool, part of the Linux procps and procps-ng packages, that runs the specified command repeatedly and displays the results on standard output so the user can watch it change over time. By default, the command is run every two seconds, although this is adjustable with the -n secs argument.
A wait state is a delay experienced by a computer processor when accessing external memory or another device that is slow to respond.. Computer microprocessors generally run much faster than the computer's other subsystems, which hold the data the CPU reads and writes.
In free and open-source software (FOSS) development communities, a forge is a web-based collaborative software platform for both developing and sharing computer applications. For software developers it is an online service to host the tools they need to work and communicate with their coworkers.
The parent process may then issue a wait system call, which suspends the execution of the parent process while the child executes. When the child process terminates, it returns an exit status to the operating system, which is then returned to the waiting parent process. The parent process then resumes execution. [1]
