It is designed for Gigabit Ethernet that is backward compatible with the Category 5/5e and
Category 3 cable standards. Cat 6 features more stringent specifications for crosstalk and
system noise. The cable standard provides performance of up to 250 MHz and is suitable for
10BASE-T / 100BASE-TX and 1000BASE-T (Gigabit Ethernet).
Channel
A communications path between two computers or devices.
Checksum
The result of adding a group of data items that are used for checking the group. The data
items can be either numerals or other character strings treated as numerals during the
checksum calculation. The checksum value verifies that communication between two
devices is successful.
CIFS

network administrators centrally manage and automate the assignment of IP addresses on
a computer network. Each system that connects to the Internet/intranet needs a unique IP
address.

A strategy that allows a company to return to normal activities after a catastrophic
interruption. Through failover to a parallel system or by restoration of the failed system,
disaster recovery restores the system to its normal operating mode.
Disk Roaming
This is the process of removing a disk drive from a controller and putting it back later,
either on the same controller, or a different one, and having it recognized as the same disk
drive. The disks may be can be attached to different ports than they were originally
attached to, without harm to the data. The disks may be attached to the same ports or
different ports on the controller.
DNS
Short for Domain Name Service. A network service that translates domain names into IP
addresses using a server that maintains a mapping of all host names and IP addresses.
Normally, this mapping is maintained by the system administrator, but some servers
support dynamic mappings.
