Anonymous users2024-02-10ADSL (Asymmetric Digital Subscriber Loop) technology is a technology that realizes broadband access interconnection network by asymmetric digital subscriber line, ADSL as a transport layer technology, makes full use of the existing copper line resources, and provides a bandwidth of 640Kbps uplink (1Mbps uplink theoretically, 1Mbps uplink can be fully supported in ADSL 2+ standard) and 8Mbps downlink on a pair of twisted pair cables. Thus overcoming the traditional user in"The last mile"of"Bottlenecks", to achieve broadband access in the true sense. The uplink bandwidth refers to the data frequency range when the user's computer sends information to the network, and the downlink bandwidth refers to the frequency fluctuation range when the network sends information to the user's computer. For example, if you use FTP to upload files to the Internet, the uplink bandwidth will affect the upload speed. And from the online ** file, the downlink bandwidth affects the ** speed.
Of course, in the actual transmission process, the quality of the line, equipment (including computers and other equipment) will also have a greater or less impact on the speed. The uplink rate is the speed at which data is sent, and the downlink is the speed at which data is received. For example.
ADSL has an uplink rate of 640Kbps to 1Mbps and a downlink rate of 1Mbps to 8Mbps. The prevailing one is 2Mbps
The downlink is the speed at which the data is received.

Anonymous users2024-02-09It's very simple that the uplink is the network occupied by the data on your computer sent out, such as sending an email to a QQ friend, all of which are uplink to occupy the uplink bandwidth, and the downlink is the process of network resources to your computer, such as ** movies and browsing the web These are all called downlink,

Anonymous users2024-02-08The uplink rate generally refers to the speed at which someone else communicates from your computer!
Generally, the uplink and downlink speeds of ADSL Internet access mode are asymmetrical, and the downlink rate is generally high.

Anonymous users2024-02-07Broadband uplink and downlink refers to the uplink and downlink rates of the general ADSL Internet mode, the uplink is the speed of uploading from the computer, and the downlink is the speed of the host on the network, and the general downlink rate is relatively high!

Anonymous users2024-02-06Broadband uplink and downlink refers to the uplink and downlink rates of general ADSL Internet access.
The uplink bandwidth is the uplink rate, which generally refers to the speed at which others can communicate from your computer.

Anonymous users2024-02-05The actual transmission speed should also be divided into uplink and downlink, the uplink rate is the speed of sending out data, and the downlink is the speed of receiving data.
Broadband. There is no strict definition of broadband. From a general point of view, it is the bandwidth that can meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept.
Generally speaking, the ideal optical fiber is equal to the uplink and downlink, but in reality, it is generally asymmetrical uplink and downlink fiber, but it is higher than the ordinary ADSL broadband uplink and downlink (ordinary ADSL uplink can reach up to 890, but the service provider will generally not give you that high, 1m uplink is 352kb, 2m uplink is 352kb, 4m uplink is generally 512 or 600 kb,** The maximum bandwidth of the line can reach 12m, and the ideal maximum bandwidth is below 8m), the optical fiber is different, the downlink is the same as your ** maximum, but the uplink is generally more than 1m value, that is, your upload rate can reach up to about 1m. Although you can apply for the downlink, as long as you have money and the total bandwidth is enough, you can almost meet the needs of as much as you want.

The upward official documents of the higher-level organs and the lower-level organs are transferred to the subordinate units in accordance with the relevant language, which is generally called a forwarding notice. >>>More
Optical fiber broadband converts the data to be transmitted from electrical signals to optical signals for communication. At both ends of the optical fiber, there are "optical modems" for signal conversion. >>>More
The uplink bandwidth cannot be canceled, because the network is all interactive, you don't go up the command, and the network can't give you downlink data, the uplink broadband refers to the data frequency range when the user's computer sends information to the network, and the downlink bandwidth refers to the frequency fluctuation range when the network sends information to the user's computer. For example, if you use FTP to upload files to the Internet, the uplink bandwidth will affect the upload speed. And from the online ** file, the downlink bandwidth affects the ** speed. Of course, in the actual transmission process, the quality of the line, equipment (including computers and other equipment) will also have a greater or less impact on the speed.
