2 laser, either accidentally or as a result of someone else's
deliberate action (misuse) will be protected from injury by their
natural blink reflex. This is a natural involuntary response which
causes the individual to blink and avert their head thereby
terminating the eye exposure.
D
DHCP
Short for Dynamic Host Configuration Protocol, a protocol for
assigning dynamic IP addresses to devices on a network. With
dynamic addressing, a device can have a different IP address
every time it connects to the network. In some systems, the
device's IP address can even change while it is still connected.
DHCP also supports a mix of static and dynamic IP addresses.
DLT
Digital Linear Tape technology is owned, developed, and
manufactured by Quantum Corporation. DLT tape drives use
half-inch wide tape. DLT 8000 tape drives record on 208 tracks
(uncompressed).
DNS
Short for Domain Name System (or Service or Server), an Internet
service that translates domain names into IP addresses. Because
domain names are alphabetic, they're easier to remember. The
Internet however, is really based on IP addresses. Every time you
use a domain name, therefore, a DNS service must translate the
name into the corresponding IP address. For example, the
domain name www.example.com might translate to
198.105.232.4.
E
Elements
SCSI designation for any device or bin in the library that can
hold a cartridge. SCSI elements include storage slots, tape drives,
load port slots, and the gripper.
EMI
Electro-Magnetic Interference refers to unwanted electrical noise
present on a power line. This noise may "leak" from the power
lines and affect equipment that isn't even connected to the power
line. Such "leakage" is called a magnetic field. Magnetic fields are
formed when unwanted noise voltages give rise to noise
currents. Such noise signals may adversely affect electronic
equipment and cause intermittent data problems.
ESD
Electrostatic Discharge
H
Host
The device or devices to which the library is connected.
