This connection remains in place for the duration of the communication. Internet communication and access to data has not typically involved a point to point connection. Rather, the sender transmits self-contained packets of data bearing the destination address. The computers that comprise the backbone of the Internet read th e address and send the packets to their destination by the most efficient route available. Until recently, this technology did not support voice communication.
Internet telephony is inexpensive.
Under a 1983 FCC decision, ISPs are Enhanced Service Providers and as such are en titled to a flat business rate for local calls. This allows ISPs to provide voice communication for less than its true cost. Telephone companies have also entered the ISP market. WorldCom recently bought MFS and UUNet. Th e picture is further complicated by the development of wireless and satellite technologies for communication.
