ADSL supports uplink 5 12kbps ~ 1mbps and downlink 1mbps ~ 8Mbps, but its speed largely depends on the line quality and the distance between you and the access computer room (the effective transmission distance is 3 ~ 5km), so it is impossible to reach 8Mbps in practical application, which is the defect of this technology itself.
The so-called broadband service of Netcom used by your classmate is different from ADSL, and it is called Broadband King.
The speed of the broadband king depends on two points: 1. At present, the interface of switch is generally 10 megabit.
2. The network situation of the whole community, all broadband users in the community are enjoying the export bandwidth of the community. At the same time, there are more people surfing the Internet in the community, and everyone's network speed will slow down.
If the broadband king of 10Mb uses thunder, its theoretical peak value is 1.25MB, which can actually reach about 1. 1.
So in theory, broadband king is a little faster than AD, but in fact, broadband king is much faster than AD.
It is recommended that you use the speed measuring website:
/
After the plug-in is installed, you can measure the speed.
Then consult Netcom to see if the speed you measured meets their promised speed.
As for you, how can his family use the bandwidth of 1 0 trillion on160? Operators use a monthly subscription policy instead of charging by traffic, so they treat users equally.
Unfortunately, ADSL can only be used in communities without broadband access.
