Anonymous users2024-02-12Broadband uplink and downlink refers to the uplink and downlink rates of general broadband or optical fiber Internet access, uplink is the speed of uploading from the computer, downlink is the speed of the host on the network, and the general downlink rate is relatively high!
The uplink and downlink rates of telecom broadband follow the following conventions:
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;
2) For broadband with a downlink rate greater than 4Mbps but less than 20Mbps, the uplink rate is 1Mbps;
3) For broadband with a downlink rate greater than or equal to 20Mbps but less than 100Mbps, the uplink rate is 2Mbit/s;
4) Broadband with a downlink rate equal to 100Mbps and an uplink rate of 4Mbps.
5) Broadband with a downlink rate equal to 200Mbps and an uplink rate of 10Mbps.
2. For the broadband accessed by ADSL ADSL2+ VDSL, the uplink rate is 512Kbps.

Anonymous users2024-02-10What is Upstream Bandwidth?
Answer: The uplink bandwidth is the bandwidth of local uploads, and the upload bandwidth requirements of servers are relatively large.
What is downstream bandwidth?

Anonymous users2024-02-09ADSL (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 is necessary to divide with 8
So the actual speed is only about 50k.

Anonymous users2024-02-08Bandwidth is not speed, but bandwidth determines speed, uplink can be understood as data from your local area, downlink is just the opposite;
Bandwidth can be understood as the channel capacity of data transmission, generally speaking, ordinary broadband users (that is, we often call ADSL users), the uplink bandwidth is generally, and the downlink bandwidth is; And our general LAN, IP metro, or most of the broadband accessed by network cable (with RJ45 crystal head), the uplink and downlink bandwidth are usually the same, of course, this only refers to the local, the real speed that can be achieved, and many external factors, such as egress bandwidth, network usage.
For when you use Thunderbolt to get a movie, you feel that your uplink bandwidth is super high, which is mainly related to Thunderbolt's ** way, it is a bit similar to BT,, in other words, when you are in the next movie, you can also be for other people's ** source, if you just started, it should be more downlink than uplink, but when you go down to the later stage, there will be more uplink than downlink, because, at this time, many of your **source has ended, and you are providing ** for others**, So there will be an upside super-high.
The width of the frequency band. In communication, it refers to the difference between the highest and lowest frequencies in a frequency band (in hertz); In the context of a computer network, it refers to the amount of data transmission capacity (measured in bits and seconds). >>>More
In computer networks and IDC rooms, the unit of network transmission rate is expressed in b s (bits per second) (or bit s, sometimes written as bps, that is, bit per second). >>>More

The backplane bandwidth of a switch is the maximum amount of data that can be handled between the switch's interface processor or interface card and the data bus. The backplane bandwidth indicates the total data exchange capacity of the switch, which is measured in Gbps, also known as switching bandwidth, and the backplane bandwidth of a general switch ranges from a few Gbps to hundreds of Gbps. >>>More
The bit width of the video memory is the number of bits of data that can be transmitted by the memory in a clock cycle, and the larger the number of bits, the greater the amount of data that can be transmitted in an instant, which is one of the important parameters of the video memory. At present, there are three kinds of memory widths on the market: 64-bit, 128-bit and 256-bit, and people are accustomed to calling 64-bit graphics cards, 128-bit graphics cards and 256-bit graphics cards to refer to their corresponding memory bit widths. The higher the memory bit width, the better the performance**, so the 256-bit wide video memory is more used in high-end graphics cards, while mainstream graphics cards basically use 128-bit video memory. >>>More
