Today the term "task" is used very ambiguously. For example, the Windows Task Manager manages (running) processes, while Windows Task Scheduler schedules programs to execute in future, what is traditionally known as a job scheduler, and uses the .job extension. By contrast, the term "task queue" is commonly used in the sense of "units of work".
In multiprogramming systems, a task runs until it must wait for an external event or until the operating system's scheduler forcibly swaps the running task out of the CPU. Real-time systems such as those designed to control industrial robots, require timely processing; a single processor might be shared between calculations of machine movement ...
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.
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 .
A ready queue or run queue is used in computer scheduling. Modern computers are capable of running many different programs or processes at the same time. However, the CPU is only capable of handling one process at a time. Processes that are ready for the CPU are kept in a queue for "ready" processes. Other processes that are waiting for an ...

Windows Vista uses Task Scheduler 2.0 to run various system-level tasks; [22] consequently, the Task Scheduler service can no longer be disabled (except with a simple registry tweak). Task Scheduler 2.0 in Windows 7. Task Scheduler 2.0 exposes an API to allow computer programs and scripts create tasks. [19] [23] It consists of 42 COM interfaces ...
A Deferred Procedure Call (DPC) is a Microsoft Windows operating system mechanism which allows high-priority tasks (e.g. an interrupt handler) to defer required but lower-priority tasks for later execution. This permits device drivers and other low-level event consumers to perform the high-priority part of their processing quickly, and schedule ...
