Mbps: Megabits per second. One megabit is 1,048,576 (10242) bits.
NAT: Network Address Translation is a transparent routing function that
translates a Private IP address on a PAT into a Public address that
can be used in a public network.
Network address: The network portion of an IP address.
Network protocol: Network protocols encapsulate and forward data packets from one
interface to another.
Noise: Unwanted interference to a transmitted signal by an outside source.
PAT: Port Address Translation is a form of NAT that maps multiple
