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.

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.

Control System Plus
(TACACS+)
A technology that checks your network for any loops. A loop can often
occur in complicated or backup linked network systems. Spanning Tree
detects and directs data along the shortest available path, maximizing
the performance and efficiency of the network.

TACACS+ is a logon authentication protocol that uses software
running on a central server to control access to TACACS-compliant
devices on the network.

Protocol suite that includes TCP as the primary transport protocol, and
IP as the network layer protocol.

Trivial File Transfer
Protocol (TFTP)
A TCP/IP protocol commonly used for software downloads.
