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.
