To shut down or power off a computer is to remove power from a computer's main components in a controlled way. After a computer is shut down, main components such as CPUs, RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, may retain power.
"Shutdown" is a song by English rapper Skepta. It was released as the second single from Skepta's fourth album Konnichiwa (2016) on 26 April 2015 through Boy Better Know. A music video for the song was uploaded to YouTube on the day of the song's release. "Shutdown" peaked at number 39 on the UK Singles Chart. The song samples speech from a Vine video created by Canadian rapper Drake. The song was covered by English rock band Slaves in the BBC Radio 1 Live Lounge.
In economics, a firm will choose to implement a shutdown of production when the revenue received from the sale of the goods or services produced cannot even cover the fixed costs of production. In that situation, the firm will experience a higher loss when it produces, compared to not producing at all.
Technically, shutdown occurs if marginal revenue is below average variable cost at the profit-maximizing positive level of output. Producing anything would not generate revenue significant enough to offset the associated variable costs; producing some output would add losses (additional costs in excess of revenues) to the costs inevitably being incurred (the fixed costs). By not producing, the firm loses only the fixed costs.
In a nuclear reactor, shutdown refers to the state of the reactor when it is subcritical by at least a margin defined in the reactor's technical specifications. Further requirements for being shut down may include having the reactor control key be secured and having no fuel movements or control systems maintenance in progress.
The shutdown margin is defined in terms of reactivity, frequently in units of delta-k/k (where k is taken to mean k-effective, the effective multiplication factor) or occasionally in dollars (the dollar is a unit equal to the change in reactivity needed to go from critical to prompt critical). Shutdown margin can refer either to the margin by which the reactor is subcritical when all control rods are inserted or to the margin by which the reactor would be shut down in the event of a scram. Hence, care must be taken to define shutdown margin in the most conservative way in the reactor's technical specifications; a typical research reactor will specify the margin when in the cold condition, without xenon. Under this specification, the shutdown margin can be simply calculated as the sum of the control rod worths minus the core excess.
Minimum shutdown margin can be calculated in the same way as shutdown margin, except that the negative reactivity of the most reactive control rod and non-scramable rods is ignored. This definition allows the reactor to be designed so that it remains safely shut down even if that most reactive control rod becomes stuck out of the core.
A reactor is in cold shutdown when, in addition, its coolant system is at atmospheric pressure and at a temperature below . This temperature is low enough that the water cooling the fuel in a light water reactor does not boil even when the reactor coolant system is de-pressurized.

Critical mass was a shiny, polished concept from the gray halls of the universities and space agencies on Earth, but it had its dark side-a side discussed only in hushed conversations among the planners who hung out during late hours in what passed for dim bars in Mars City: they would have to reach critical mass before they could survive a catastrophic shutdown of the supply lines from Earth-a shutdown that could happen any day because of an economic collapse Earthside, a spacecraft disaster at Crystal City or Phobos, or worse.
