The broadband network speed of 1M actually reaches 800kb! What s going on?

Great Wall broadband should belong to the type of community broadband, if there are few people in the community, the network speed will be fast, if there are more people in the community, the network speed will be slow. It is estimated that in the community of your friend's house, no one uses Great Wall broadband (it is estimated that there are many telecommunications or Netcom), and the so-called 1m of Great Wall broadband should be the highest value that can be achieved. If you live in the same neighborhood as him, you can consider changing to Changcheng broadband, on the contrary, you had better find out how many people in your community use Great Wall broadband, so as not to change it slower than the original.

The advantage of telecommunications and Netcom is that it is stable, no matter what time period, how many people are online at the same time, the network speed can be guaranteed, therefore, these two types of broadband are the least affected by external factors.

Chenshuangcn is not right.,The length and width are now basically completed EPON transformation,Shared LAN was in the early days,But now it's all changed to PPPoe dial-up,How much bandwidth is the external network exit (you let your friend save a single thread from the telecom server as a casual ** file can be seen,It's definitely about the same as your 123k speed),As for him**fast, because there are resources in the long and wide intranet when using Thunder** (there are also people below),Many people in the intranet** The same resource,P2POf course, it's very fast,If there are a little resources in the intranet, I'm ** speed is on 1m,I use the G enjoy standard version of the 2M external network + 4M the length and width of the internal network,Now Shanghai Telecom 188 months E8 199 months E9 are all 10M,You can install it (unfortunately I returned the adsl last year)

1MB = 1024KB, 80MB = 81920KB, net car speed.

80Mbps is 81,920 KB of data per second.

The unit of data accessed in a computer is "byte", that is, byte (uppercase B), and data communication is based on "character bit", i.e., bit (lowercase B), and the relationship between the two is 1byte = 8bit.

The network speed mentioned in the telecommunication service is 1m, 2m, 3m, 4m, etc., which is calculated in the unit of data communication. Therefore, when the speed displayed by the computer software is 200kb, the actual line connection and closing cavity rate is not less. Key Bureau.

1. China Unicom is really not good, you have to see whether the gigabit network opened for you is exclusive.

2. This phenomenon is not necessarily a problem with Unicom, it may be a problem with equipment, or a problem with people 3. A problem with a router or a problem with a mobile phone.

Let me give you a rough idea, there is a difference between mobile phones and mobile phones, some people have a single antenna for mobile phones, and some people have dual antennas for mobile phones, it doesn't matter if this mobile phone is broken or not! Single-antenna mobile phones naturally have to suppress the internet speed. In addition, if you have a lot of people surfing the Internet, or someone is surfing the Internet, the Internet speed will also fluctuate.

The theoretical value of the broadband rate is:

2Mbps: It can reach about 256kb s, and no less than 150kb s is normal;

4Mbps: It can reach about 512kb s, and no less than 300kb s is normal;

6Mbps: It can reach about 768kb s, and no less than 450kb s is normal;

10Mbps high-speed broadband** normal rate uplink 100kb s, downlink 1000kb s;

1000Mbps high-speed broadband** Normal rate uplink 10000KBS 10MB s, downlink 10000KBS 100MB s.

The speed of 1000M is 1000Mbps, which is 1000Mbit per second, and the speed of your ** is MB, that is, Mbyte, and the conversion relationship is 8bits=1byte, so your actual speed is 1000Mbps 8=125Mbps, that is to say, 1000M's broadband, ** when reaching 100-130Ms is normal.

This is a normal phenomenon, every day you say sue and sue sue, but in reality it is not as fast as you think.

300KB = 2400KB, 300KB seconds = 2400KB seconds, where KBit is the bandwidth applied for at the ISP service provider, that is.

There is also a part of the attenuation on the line, so it is generally calculated as 1KB=10KBbit, that is, the bandwidth of 3M is applied for, and it is removed.

Yours is 1m

Next, find something at will**. **Speed 1 sec 90-110k, is 1m sec 190-210k is 2m sec 400-430k is 4m. And so on.

Yes, that's how I understand it. However, it is necessary to pay attention to the unit, most people are confused or misunderstood because of the unit.

Broadband operators, whether domestic or foreign, the unit of broadband speed is the bit (word), and the commonly used speed unit is byte (byte), 8bit is equal to 1byte, so theoretically 100MB of broadband, **speed is, pay attention to the case of the letter b.

You will see a lot of similar misunderstandings on the Internet, complaining about the speed of the Internet because you don't know how to understand the unit.

Marked "greasy", in fact, this unit is an international practice. It's like hard disk capacity.

Similarly, the advance rate is 1000 instead of 1024, which causes the hard disk capacity to seem to "shrink" in Windows.

Of course, these details can indeed be improved and made more unified to make it easier for consumers to understand. However, this kind of problem involving the reform of the standard of the whole industry, and there is no growth of interests after the change, and once it forms a habit, it will be degenerated, and it is not good to change it again.

100m broadband means, this Internet access speed is 100 megabytes, broadband is the meaning of Internet access, broadband network, simply put, refers to a high-bandwidth network. To be precise, it is now a fiber optic network, and the speed of this fiber broadband network is 100m.
