The list must be enclosed in quotation marks. These targets are specified as follows: To add to the list of SNMP targets ensure that you include the existing values in the command.
Yellow green Single vs. The rule was intended to set a safe limit on the current able to pass through any single output wire. A sufficiently large current can cause serious damage in the event of a short circuitor can melt the wire or its insulation in the case of a fault, or potentially start a fire or damage other components.
Each rail delivers up to a limited amount of current through one or more cables, and each rail is independently controlled by its own current sensor which shuts down the supply upon excess current. Unlike a fuse or circuit breakerthese limits reset as soon as the overload is removed.
Obviously, if the group of wires is limited to 20A, so is each wire in it. The current limits for each group of cables is then documented so the user can avoid placing too many high-current loads in the same group. Originally at the time of ATX 2.
When the assignment of connectors to rails is done at manufacturing time it is not always possible to move a given load to a different rail or manage the allocation of current across devices.
In some cases, in violation of their own advertising claims to include it. The requirement was withdrawn as a result, however the issue left its mark on PSU designs, which can be categorized into single rail and multiple rail designs.
Both may and often do contain current limiting controllers. As of ATX 2. A multiple rail design does the same, but limits the current supplied to each individual connector or group of connectorsand the limits it imposes are the manufacturer's choice rather than set by the ATX standard.
The reasons given for this approach to power supply are that it eliminates cross-load problems, simplifies and reduces internal wiring that can affect airflow and cooling, reduces costs, increases power supply efficiency, and reduces noise by bringing the power supply fan speed under the control of the motherboard.
Power rating[ edit ] The overall power draw on a PSU is limited by the fact that all of the supply rails come through one transformer and any of its primary side circuitry, like switching components.
This protects against system performance degradation, and against power supply overloading. Power supplies label their total power output, and label how this is determined by the electrical current limits for each of the voltages supplied.
Some power supplies have no-overload protection. The system power consumption is a sum of the power ratings for all of the components of the computer system that draw on the power supply.
The manufacturers of these computer system components, especially graphics cards, tend to over-rate their power requirements, to minimize support issues due to too low of a power supply.
Green computing and 80 Plus Various initiatives exist to improve the efficiency of computer power supplies. Climate Savers Computing Initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient power supplies.
Efficient power supplies also save money by wasting less power; as a result they use less electricity to power the same computer, and they emit less waste heat which results significant energy savings on central air conditioning in the summer.
The gains of using an efficient power supply are more substantial in computers that use a lot of power. Although a power supply with a larger than needed power rating will have an extra margin of safety against overloading, such a unit is often less efficient and wastes more electricity at lower loads than a more appropriately sized unit.View Homework Help - Unit 2.

Unit 2 Assignment 1 Disk Redundancy Research plombier-nemours.com stands for Redundant Array of Inexpensive Disks and at the simplest level it combines many disks into one logical driveWe use RAID to avoid the lagging of computer performance.
The basic idea of RAID combined multiple small, inexpensive disk drives into an array of disk drive which yields performance exceeding that of a large expensive drive.
This provides an alternative to the use of output parameters for returning multiple values from a function. This dates to CLU (), and CLU helped popularize parallel assignment generally.. In C and C++, the comma operator is similar to parallel assignment in allowing multiple assignments to occur within a single statement, writing a = 1, b = 2 instead of a, b = 1, 2.
