3-Computer Science-Internet-Levels

internet-0

All devices can interconnect {internet-0}.

internet-1

Current Internet connects computers {internet-1}. Software generates communication-line signals, encodes and decodes, sends and receives packets, assembles and disassembles packets, and standardizes packet contents.

internet-2

Internet can be high-speed {internet-2}.

bit size on Internet

Speed times sending time can be bigger or smaller than network size {bit size}. If bit size is bigger, there is no overlap, so network does not need special hubs, cables, and transceivers to coordinate different amplitudes, frequencies, and phases. System has no reflections or refractions. At gigabit-per-second speeds, in Internet, bit size is 30 centimeters. At megabit-per-second speeds, in home networks, bit size is 300 meters.
