Power management is
a quality of some electrical appliance, in particular copiers,
computers and computer peripherals such as monitors and printers
that turns off the power or switches the system to a low-power
state when inactive. One power management standard for computers
is ACPI, which supersedes APM.
The Advanced arrangement and Power Interface (ACPI) specification,
an open industry standard first released in December 1996
developed by HP, Intel, Microsoft, Phoenix, and Toshiba defines
common interfaces for hardware recognition, motherboard and
device configuration and power management. According to its
specification, "ACPI is the key element in Operating
System-directed configuration and Power Management (OSPM)".
Advanced Power Management (APM) is an API
developed by Intel and Microsoft which enables an operating
system running an IBM-compatible personal computer to work
with the BIOS to achieve power management.
A network operations center
is one or more locations from which control is exercised over
a television broadcast, computer or telecommunications network.
NOCs
are responsible for monitoring the network for alarms
or certain conditions that may require special attention
to avoid impact on the networks performance.
Telecommunications
setting NOCs are responsible for monitoring for power failures,
communication line alarms such as bit errors, framing errors,
line coding errors, and circuits down and other performance
issues that may affect the network. NOCs analyze problems,
perform troubleshooting, communicate with site technicians
and other NOCs, and track problems through resolution.
If necessary, NOCs escalate problems to the appropriate personnel.
For severe conditions that are impossible to anticipate such
as a power failure or optical fiber cable cut NOCs have procedures
in place to immediately contact technicians to remedy the
problem.
