... The DS-1 signal carries 24 DS-0 channels, but its rate is more than 24 times 64 kb/s. The additional bits are used to accommodate DS-0 channels with rates that deviate from the nominal 64 because the signals are generated using clocks that are not perfectly synchronized. Since the 1980s the tran ...

The original TCP/IP protocol suite was defined as having four layers: host-tonetwork, internet, transport, and application.
