Front 9

data backups:

Back 9

The process of copying information to a different medium and storing it (preferably at an off site location ) so that it can be used in the event of a disaster.

Front 10

disaster recovery:

Back 10

The procedures and processes for restoring an organizations IT operation following a disaster.

Front 11

Disaster recovery plan(DRP):

A written document that details the process for restoring IT resources following an event that causes a significant disruption in service.

Front 12

faraday cage:

Back 12

A metallic enclosure that prevents the entry or escape of an electromagnetic field

Back 13

The application of science to questions that are of interest to the legal profession.

Front 14

heating, ventilation, and air conditioning(HVAC):

Back 14

Front 16

hot aisle/cold aisle:

Back 16

A layout in a data center that can be used to reduce heat by managing the air flow.

Front 17
