What is the broadband rate and how is it calculated

Broadband rate (fiber rate, broadband network speed) refers to the maximum theoretical rate value that can be achieved technically, generally the speed of upload and **, the higher the rate, the faster the upload and **. The broadband service rate applied by the user is the maximum theoretical rate value, because the user is also affected by the configuration of computer software and hardware, the router rate, the maximum rate that the mobile phone can support, and the WiFi signal strength when the user surfs the Internet. The impact of the address of the browsing**, the bandwidth of the peer**, etc., therefore, the rate at which the user surfs the Internet is usually lower than the theoretical rate value.

In the internet speed calculation.

b=bit ,b=byte

8 b = 1 b means that 8 lowercase b is an uppercase b, and the definitions of the two are different, so don't confuse them.

For example, to calculate 4m theoretical ** speed: 4m is 4mb s theoretical ** speed formula: 4 1024 8 = 512kb s, please note that according to the formula, the unit has changed to kb s

1. The rate unit of bandwidth is bit, that is, bit (pronunciation: bit);

There is an 8-fold relationship between bytes and bits: 1 byte = 8 bits.

For example, apply for 8 megabit ADSL broadband.

It is a rate of 8 megabits, you see that the highest peak of the actual ** rate displayed on the computer is 1 mb s, which means that the ** rate is 1 megabyte second, and if you convert it to bits, you need to multiply it by 8, which is 8 megabits per second; That is, the broadband with an access rate of 8 megabits, and the theoretical ** rate of 1 megabyte per second, are consistent.

It is recommended to use broadband between 6-20m, 6m broadband is suitable for daily use, for users who do not have much demand, 20m is used for multiple people to see**, and it is more suitable to see higher picture quality.

1kbps 1024bps, 1mbps = 1024kbps, that is to say, 1mbps bandwidth is 1024 8 125kb s in terms of speed, and 125kb data can be used in one second. In layman's terms, the theoretical speed of broadband is equal to the bandwidth divided by 8, and there is usually a gap of about 20% between the actual speed and the theoretical speed due to the loss of broadband lines.

The disk space occupied by the page is about 80kb, and the standard for smooth browsing of the web page is that the page takes no more than 2 seconds, and the data must be 40kb per second, and the bandwidth required is 40*8 320kbps. So, the bandwidth of 4M, properly.
