User Datagram Protocol (UDP)
UDP
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.
Virtual LAN (VLAN)
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.
XModem
A protocol used to transfer files between devices. Data is grouped in 128-byte
blocks and error-corrected.
