Internet Resources Fast Facts, Last Updated:09/09/2010 Unlike older communications systems, the Internet protocol suite was
deliberately designed to be agnostic with regard to the underlying physical
medium. Any communications network, wired or wireless, that can
carry two-way digital data can carry Internet traffic. Thus,
Internet packets flow through wired networks like copper wire,
coaxial cable, and fiber optic; and through wireless networks like
Wi-Fi. Together, all these
networks, sharing the same high-level protocols, form the
Internet. |
