This leads to under utilization of the network's resources. The number of circuits that connect one telephone switch stations to another is much less than the number of users connected to a single switch. The number of interconnecting circuits depends on the average use of the system. Others remain connected all day. Packet Switching vs. Circuit Switching Telephony measures capacity in terms of symmetrical two-way between two points.
Digital telecommunication measures one-way packet transmission capacity in terms of bits per second.
Modern telephone systems transmit conversations digitally at a rate of 64 Kbps. Therefore, a telephony circuit is a datastream of 64 APBs. Most telephone conversations consist of an equal amount of information traveling between the two parties at either end of the circuit. On the other hand, the World Wide Web is asymmetrical - the request for information sent from a client to a server is a few bites of information, which initiates an avalanche of information being sent back to the client computer. As an education tool, the following Information Pages have been prepared.
