TCP/IP
Short for Transmission Control Protocol/Internet Protocol. The basic protocol used for data
transmission over the Internet.
Trap
A signal from a device informing an SNMP management program that an event has
occurred.
U
A standard unit of measure for designating the height in computer enclosures and rack
cabinets. One U equals 1.75 inches. For example, a 3U server chassis is 5.25 inches high.
UDP
Short for User Datagram Protocol. A communications protocol for sending messages between
computers in a network that uses the Internet Protocol (IP). UDP is an alternative to the
Transmission Control Protocol but, unlike TCP, does not guarantee reliability or ordering of
data packets.
UPS
Short for Uninterruptible Power Supply. A device that allows a computer to keep running for
a short time when the primary power source is lost. It also provides protection from power
surges. A UPS device contains a battery that starts when the device senses a loss of power
from the primary source.
URL
Short for Uniform Resource Locator. A Web address.
USB Port
USB is short for Universal Serial Bus. A USB port is a hardware interface for low-speed
peripherals such as the keyboard, mouse, joystick, scanner, printer, and telephony devices.
Web Management Interface
A Web-based utility used for configuration and ongoing maintenance, such as monitoring
server conditions, configuring email alerts for key events, or for SNMP management.
Windows Domain Authentication
Windows-based networks use a domain controller to store user credentials. The domain
controller can validate all authentication requests on behalf of other systems in the domain.
The domain controller can also generate encrypted challenges to test the validity of user
credentials. Other systems use encrypted challenges to respond to CIFS/SMB clients that
request access to a share.
WINS
Short for Windows Internet Naming Service. The server that locates network resources in a
TCP/IP-based Windows network by automatically configuring and maintaining the name
and IP address mapping tables.
Workgroup
A collection of computers that are grouped for sharing resources such as data and
peripherals over a LAN. Each workgroup is identified by a unique name.
