TFTP
Trivial File Transfer Protocol. A TCP/IP protocol commonly used for software
downloads.
UDP
User Datagram Protocol. UD
P
provides a datagram mode for packet-
switched communications. It uses IP as the underlying transport
mechanism to provide access to IP-like services. UDP packets are delivered
just like IP packets – connection-less datagrams that may be discarded
before reaching their targets. UDP is useful when TCP would be too
complex, too slow, or just unnecessary.
UTC
Universal Time Coordinate. UTC is a time scale that couples Greenwich
Mean Time (based solely on the Earth’s rotation rate) with highly accurate
atomic time. The UTC does not have daylight saving time.
VLAN
Virtual LAN. A Virtual LAN is a collection of network nodes that share the
same collision domain regardless of their physical location or connection
point in the network. A VLAN serves as a logical workgroup with no
physical barriers, and allows users to share information and resources as
though located on the same LAN.
XM
ODEM
A protocol used to transfer files between devices. Data is grouped in 128-
byte blocks and error-corrected.
