What is the speed of 4 megabytes kb s ??

It's basically like this, it's all insufficient.

Theoretically, the speed of 4m is 512kb s.

Because the unit of network speed bandwidth is bps (which can be understood as b per second), b represents bit (a bit of information, and the information contained in a binary number is one bit. For example, 11110000 is 8 bits).

Therefore, the theoretical transmission rate of 4M bandwidth is 4M = 4 * 1024 KB 8 = 512 KB s

The 2M one is 256KB S, but that's all theoretical. In fact, the 2M provided to us by the network ** provider is about 220KBS at most, and the 4M is 350KBS. Your 328kb s is considered normal, and it is possible to reach 350 after a few more tests.

As far as I know, there is no 3m available yet. The upstairs 4m is up to 400+ kb s that's because he is in the community, pulling the optical fiber, don't believe you ask him yourself. The number of the ** line is what I said, although there is a deviation, but the difference is not far.

It is OK to test more than 400kb in the Unicom computer room, but after arriving at the user's home, the attenuation of signal transmission through the ** line is considered.

There is a high probability that it will not reach more than 400.

380.

It's normal.

Hehe, the Internet speed of 4M is good, but you can also choose to use it. Law. Lowe.

Bit. It might be a little faster with this.

Theoretically, 320 is 4 megabytes, depending on the place and the peak period of Internet access, I am 4 megabytes, usually 400, and sometimes more than 300 points.

4m=512kb/s=4096kbps。

The units of network transmission data k (thousand), m (mega), g (gid) are not calculated according to 1000 of the decimal liquid transport bucket, but are calculated according to the 10 power of the binary 1024;

1kb = 1024 * 8bit (English bit = English abbreviation as b = Chinese digits), 1m = 2 to the 10th power kb = 1024b (quietly check b = byte = byte = 8b) = 1024 * 1024 * 8b, grinding 1g = 2 10 power 10 2 m = 1024 * 1024 kb = 1024 * 1024 * 1024 * 8b.

The broadband network speed mentioned in the carrier's product introduction refers to the physical interface rate between the user's modem and the telecom broadband access equipment (DSLAM). And the technical characteristics of ADSL determine the difference in uplink and downlink rates.

The unit of access data in the computer core key is "byte", that is, byte (uppercase B), and data communication is based on "character change", that is, 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 rate is not less.

1mb=1024kb

Considering the various losses in data transmission and the performance of computer terminals, it is impossible to reach the theoretical value of network speed, such as the data of the Ministry of Industry and Information Technology, as of the end of November 2016, the fixed broadband access rate reached 48Mbps, and the Broadband Development Alliance released the 14th "China Broadband Speed Status Report" shows that in the fourth quarter of 2016, the average ** speed of China's fixed broadband network reached Mbps.

The units of capacity from largest to smallest are: bytes TB (T), GB (G), MB (G), KB, bytes (B).

The relationship between them:

1tb=1024gb

1gb=1024mb

1mb=1024kb

1KB = 1024 bytes.
