Trivial File Transfer Protocol (TFTP) 

A TCP/IP protocol commonly used for software downloads. 

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.
