  2. Scheduling (computing) - Wikipedia

    en.wikipedia.org/wiki/Scheduling_(computing)

    The scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.

    Logs off a user. This is the default even without using any parameters. -a Stops shutdown.exe. It is used during a time-out period. -f Kills all running applications. -s Turns off the computer. -r: Shuts down and reboots a computer. -m[\\ Computer Name] When shutting down a network computer, allows user to choose which computer to turn off. -t xx

  4. Job scheduler - Wikipedia

    en.wikipedia.org/wiki/Job_scheduler

    A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling , as execution of non-interactive jobs is often called batch processing , though traditional job and batch are distinguished and contrasted; see that page for details.

  5. Windows NT processor scheduling - Wikipedia

    en.wikipedia.org/wiki/Windows_NT_Processor...

    In a multiprocessing environment with more than one logical processor (i.e. multiple cores or hyperthreading), more than one task can be running at the same time. However, a process or a thread can be set to run on only a subset of the available logical processors. The Windows Task Manager utility offers a user interface for this at the process ...

  6. Time-triggered architecture - Wikipedia

    en.wikipedia.org/wiki/Time-triggered_architecture

    Time-triggered architecture (abbreviated as TTA), also known as a time-triggered system, is a computer system that executes one or more sets of tasks according to a predetermined and set task schedule. [1] Implementation of a TT system will typically involve use of a single interrupt that is linked to the periodic overflow of a timer.

  7. Preemption (computing) - Wikipedia

    en.wikipedia.org/wiki/Preemption_(computing)

    In preemptive multitasking, the operating system kernel can also initiate a context switch to satisfy the scheduling policy's priority constraint, thus preempting the active task. In general, preemption means "prior seizure of". When the high-priority task at that instance seizes the currently running task, it is known as preemptive scheduling.

  8. Idle (CPU) - Wikipedia

    en.wikipedia.org/wiki/Idle_(CPU)

    The idle task can be hard-coded into the scheduler, or it can be implemented as a separate task with the lowest possible priority. An advantage of the latter approach is that programs monitoring the system status can see the idle task along with all other tasks; [ citation needed ] an example is Windows NT 's System Idle Process .

  9. Magic SysRq key - Wikipedia

    en.wikipedia.org/wiki/Magic_SysRq_key

    It is often used to recover from freezes, or to reboot a computer without corrupting the filesystem. [1] Its effect is similar to the computer's hardware reset button (or power switch) but with many more options and much more control. This key combination provides access to features for disaster recovery.
