Abstract
A communications channel has an important dependence for the channel capacity (C, in bps) to channel bandwidth (W, in Hz) ratio; this is capacity per unit bandwidth on signal to noise ratio (S/N, power of the signal over power of noise). Shannon’s formula gives an upper limit for this dependence (Shannon & Weaver, 1949), C/W=log2 (1+S/N), which represents channel efficiency. Phase lock loops for waves and data symbols in the presence of noise have been given (Reis, Rocha, Gameira, & Carvalho, 2005).

A History of Computer Networking Technology
A LAN technology developed by the IBM Corporation where the computers are arranged in a circle. In the token ring scheme, a client computer cannot transmit data unless it has a token sent by the server on the network. Token ring topology standards are described in IEEE 802.5.
