What does the uplink bandwidth and downlink bandwidth mean? What is the role of each?

What does uplink bandwidth and downlink bandwidth, or uplink and downlink speed mean? In setting the speed limit of the router, as well as the configuration of some other software often encounter the uplink speed and downlink speed, many users do not know the two represents the consciousness, not to mention configuration, the following will be a detailed introduction.

We visit the Internet in the process of these two behaviors: first, upload data, and second, download data. Uplink broadband (speed) refers to the speed of the upload, and downlink broadband (speed) refers to the download data is several times.

Uplink broadband (speed) and downlink broadband (speed) is asymmetric, generally the downlink speed is greater than the speed of the uplink. We usually use the broadband say how many m, are referring to the downlink broadband, because we are mainly from the Internet to download data, and upload the amount of data is much less.

In addition, many users have such a question, that is found in the use of broadband, found that the speed of the computer download can not reach their own processing of broadband standards, such as the processing of 10M broadband, the result download speed only 1m/s about speed, this is why?

This is because the broadband operator is not the same as the downlink speed of the Windows computer, the unit of Windows computer is Kbbs, and the unit of broadband operation is kbbs,1b=8b. For example, you are in the broadband operation where the 10M broadband, 10mbps=10240kbps/8=1280kbps, so you download the data on the computer is, your biggest download speed only 1280KBps, that is, only 1m/s about the appearance. So don't say that broadband companies deceptive, the processing of broadband deduction, which is only calculated by the different units caused.
