	Also called an Ethernet address, physical address, hardware address, or NIC address.
MB	One megabyte; equals 1,024 x 1,024 bytes, 1,024 kilobytes, or about 8 million bits.

MTU	The Maximum Transmission Unit is the largest amount of data that can be transmitted in one discrete
	message on a given physical network. The MTU places an upper bound on the size of a message that
	can be transferred by the network in a single frame. Messages exceeding the MTU must be fragmented
	before transmission, and reassembled at the destination.
