idles

Idles is a term that can refer to several related concepts in English and specialized contexts. It is the third-person singular form of the verb idle, used to describe someone or something that does not engage in activity, or that remains inactive by choice or circumstance. In mechanical and automotive usage, idling refers to an engine operating at a low, steady speed with no external load. Engine idle is controlled to maintain smooth operation and readiness to accelerate, but prolonged or unnecessary idling wastes fuel and increases emissions, leading to policies and guidelines that discourage it in many cities and workplaces.

In computing and systems engineering, idle describes states in which a processor, disk, or other component is powered but not actively processing user tasks. Entering idle or sleep modes reduces energy consumption, and modern hardware employs multiple low-power states to balance responsiveness and efficiency.

In economics and sociology, idle can describe the state of being unoccupied with paid work or underutilized resources, such as idle labor, idle capacity, or idle time. Idleness is analyzed in studies of productivity, unemployment, and social welfare, with debates about the value of rest versus the costs of inactivity.

In everyday language, idling can refer to leisure or passive time, as well as the act of letting something stand still. The term has various domain-specific meanings, but across contexts it generally denotes a lack of active engagement with a task.
