This article mainly shows you "what is the meaning of broadband uplink 30m downlink 200m in the Internet", the content is simple and clear, and I hope it can help you solve your doubts. Let me lead you to study and learn the article "what is the meaning of broadband uplink 30m downlink 200m in the Internet".

Broadband uplink 30m downlink 200m means that the rate at which local information is uploaded to the network is 30 / 8=3.75M/s, and the rate at which network information is downloaded to the local is 25M/s. Broadband has two rates: uplink and downlink, the uplink rate is the rate at which local information is uploaded to the network, and the downlink rate is the rate at which network information is downloaded to the local network.

The operating environment of this tutorial: windows7 system, Dell G3 computer.

Broadband has two rates of uplink and downlink, called uplink bandwidth and downlink bandwidth, uplink rate: the rate at which local information is uploaded to the network; downlink rate: the rate at which network information is downloaded locally.

The upstream and uplink rate of bandwidth directly affects the Internet experience. Usually, the higher the downlink bandwidth is, the faster the network download speed is. Especially with the advent of the "cloud era", users surfing the Internet are not limited to watching movies and chatting. There are all kinds of webcast, e-mobile games, Weibo and other sharing, which requires the faster and higher the uplink / downlink speed of the network!

The downlink speed used by broadband operators is different from that on Windows computers.

The unit of Windows computer is KBps, while the unit of broadband operation is kbps~.

1B=8b

So if 1Mbps bandwidth is described by download speed,

1Mbps = 1024kbps = 1024 KBps 8 KBps = 128KB/s

That is, the highest download rate in one second is 128KB.

So if you have 50m broadband at home,

50 * 128 KB/s = 6400 KB/s = 6400 / 1024 MB/s = 6.25MB/s

Therefore, in theory, the download speed of 50m broadband is only 6.25MB/s.

Therefore, the fast calculation method of the actual download speed is

Bandwidth / 8 = theoretical maximum peak speed

Broadband uplink 30m downlink 200m means that the rate at which local information is uploaded to the network is 30 / 8=3.75M/s, and the rate at which network information is downloaded to the local is 25M/s.

However, due to the aging lines of operators, peak Internet access, multi-person sharing, wireless network transmission problems and other reasons, the actual download speed and theoretical download speed usually have a gap of about 20%!

Generally speaking, the gap between upstream and uplink is not one or two megabytes. If the downlink broadband is 100 megabytes, then the uplink is estimated to be only a few megabytes, that is, if it is 100 megabytes of broadband upload speed, it can only reach 1M/S, and the download speed is generally about 9MB, but it is enough for ordinary families to use it. Stable upload is no problem.

The above is all the contents of this article "what is the meaning of broadband uplink 30m downlink 200m in the Internet". Thank you for reading!
