Traditional Internet access methods like dial-up were so slow that host computers were connected to the dial-up(71)at the customer premise over slow(72)ports. PPP was designed to run directly over these serial links. But with the advent of broadband Internet(73)technologies such as ADSL and cable modems there has been a considerable increase in the bandwidth delivered to the end users. This means that the Lost computers at the customer premise connect to the(74)or cable "modem" over a much faster medium such as Ethernet. It also means that multiple(75)can connect to the Internet through the same connection.A．bufferB．modemC．computerD．server

A typical application of this(71)is ADSL. It is emerging as the technology for home-and small-office Internet connectivity. It provides either 1.5 Mb/s～8 Mb/s from the network to the user and 64 Kb/s～512 Kb/s in the reverse direction depending on the distance, 12 000 or 18 000 feet.. The different speed for each direction gives it the(72)label. ADSL is designed to take advantage of the fact that video-on demand, telecommuting, and Internet access traffic are inherently asymmetrical. The user(73)a brief message up to the network and receives a ton of data coming back, either a movie or a piece of data download. Under such a scenario, low-speed traffic to the network is just fine. ADSL delivers high(74)where you need it and only uses a single copper pair. Through multiplexing, it also reserves(75)of the bandwidth for POTS.A．FTTHB．HFCC．FTTCD．HDSL
