Chapter 26: Internet Access and Local-Area Networks
Computer data transmission differs in fundamental ways from standard telephone voice transmission. One is that computer data flows in bursts, whereas voice traffic travels at a steady rate. This means that voice and data signals are handled differently. Although voice and data share major parts of the global telecommunications network, networks optimized for data are designed differently. This chapter covers data networks and the transmission technologies they use, then describes the networking standards that specify fiber-optic transmission.
