Anonymous users2024-02-06ADSL (Asymmetric Digital Subscriber Loop) technology is a technology that realizes broadband access to the Internet with asymmetric digital subscriber lines, ADSL as a transport layer technology, makes full use of the existing copper line resources, and provides a bandwidth of 640kbps uplink (1Mbps theoretical uplink) 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 rate generally refers to the speed at which someone else communicates from your computer!
Generally, the uplink and downlink rates of ADSL Internet access mode are asymmetrical, and the downlink rate is generally higher! The upside is relatively low! Now the normal is uplink: 386kb, downlink: 512kb!
Note that there is a difference between the rate and the actual speed! Generally, it needs to be divided by 8, so the actual speed is only about 50k!

Anonymous users2024-02-05Downlink is how fast your computer can accept data, and upstream is how fast you upload data to your server.
For example: the downlink speed here is 2m, and the uplink speed is 400k, which means that my ** speed is 2000 8=250k, and the maximum upload speed is 400 8=50k
Divide by 8 because of the conversion between bytes and bits, which you don't need to understand.

The 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.
Downlink broadband. The uplink rate is the speed at which the data is sent out, and the downlink is the speed at which the data is received.

Anonymous users2024-02-03Uplink is the data sent, for example, if you play an online game, I think the uplink is more important than the downlink.
The downward movement is the data contained in the source of the grinding, and it is the movie that you wither.
Personally, I understand that the upside and the downside are not proportional to each other, and often the upside will always be smaller than the downside
1. For LAN or FTTH access broadband users:
1) Broadband with a downlink rate of less than or equal to 4Mbps and an uplink rate of 512kbps; >>>More
A complete fitness program should include three aspects: eating (eating), exercising (training), and sleeping (sleeping), and training is composed of three main parts: cardiology, strength, and flexibility. The training plan I give is: 5-10 minutes of aerobic warm-up at the beginning, 5-10 minutes of stretching and relaxation at the end, and 40-50 minutes of strength training in between. >>>More
Left and right face asymmetry is very common in life, and many people regard left and right face asymmetry as a disease, but it is not. There are several reasons why the left and right faces are not symmetrical, one of which is that one side is used to eating and chewing food, so the side of the face that is commonly used is relatively small, and people who find that the face is asymmetrical should often pick and choose to use both sides of the meal, and the larger side of the face will chew more food. Second, the left and right face asymmetry, but also and sleep close relationship, infancy is particularly obvious, often sleep on one side of the baby on one side of the face of a large face and a small face, adults should pay attention at this time, adjust the baby's sleeping position, to avoid the size of the face asymmetry after growing up and then adjust it is more difficult.
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.
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
