Shit to remember Raid Ports 802.22 States and more Flashcards
Raid 0
Minimum 2 drives - Striping - all data lost if one is lost.
Raid 1
Minimum 2 Drives - Mirroring - capacity is half of total size
Raid 5
Minimum 3 Drives - Striping with parity . Takes time to rebuild drives
Raid 6
Minimum 3 Drives - Striping with double parity. Takes time to rebuild drives
Raid 10 (0 + 1)
Minimum 4 Drives - Performance Capacity and High Reliability. Capacity is half of total size.

Rapid elasticity
Rapid elasticity is the characteristic of scaling up or down cloud resources
with demand. More resources will be made available during busy times,
Collate
The printing of multiple copies in their proper order is called collating the
output. If the output was not collated, all of the page one copies would
print, then all of the page 2, etc.
ad hoc mode
Ad hoc mode allows two devices to directly communicate over an 802.11
wireless link without using an access point.

Cable tester
A cable tester could be used to confirm the wire map of the cable, but you
would first need to locate both ends before that would be possible. A cable
tester doesn’t provide a way to locate both ends of a cable.
Tone generator
A tone generator is used to produce an analog tone on one the cable, and
an inductive probe is used to identify the location of the cable on the other
end.
Crimper
If the RJ45 connector on the cable was faulty, a crimper could be used to
attach a new connector to the cable
Inverter
The inverter powers the CCFL (Cold Cathode Fluorescent Lamp) LCD
(Liquid Crystal Display) backlight, allowing you to easily view the pixels
on the display. Most newer laptops will use LED (Light Emitting Diode)
backlights that use the existing DC (Direct Current) power and don’t
require an inverter.
