Xiaobian to share with you to measure the computer external equipment transmission rate of the measurement units, I believe that most people do not know much, so share this article for your reference, I hope you will learn a lot after reading this article, let's learn about it!

The unit of measurement used to measure the transmission rate of external devices on a computer is: "MB/s". MB is the storage capacity, "MB/s" is the transfer rate, and "MB/s" means megabytes per second, which refers to the number of bytes transferred per second.

Basic concept

Bit (bit, also known as "bit"): the abbreviation of bit is b, which is the smallest unit of data in a computer (which belongs to binary, which actually means 0 or 1).

Byte (bytes): the abbreviation of Byte is B, which is the basic unit of calculation of computer file size. For example, a character is 1Byte, if it is a Chinese character, it is 2Byte.

Conversion

1B (bytes) = 8b (bits)

1 KB = 1024 B

1 MB = 1024 KB

1 GB = 1024 MB

1TB = 1024GB

The unit of data transfer rate is generally MB/s or Mb/s.

In terms of data transfer rate, Mb/s is generally used as a unit in official data (such as telecommunications departments).

And download software (such as IE, Thunder, Express) generally use MB/s as the unit.

Theoretical value of maximum broadband download:

1Mb/s = 0.125MB/s = 128KB/s

The M of 1m broadband said by the telecommunications department refers to Mb/s, and the transmission rate when downloading software is MB/S, that is, the fastest 128KB/s of 1m broadband download speed, and then removing the loss is about 120KB/s.

According to this statement, the fastest broadband download speed of 10m is 1.25MB and the fastest download speed of 100m is 12.5MB/s.

MB/s means megabytes per second, and Mb/s means megabits per second, the former refers to the number of bytes per second transmitted, and the latter refers to the number of bits transmitted per second. The two are completely different. Byte is the number of bytes, bit is the number of bits, in the computer every eight bits is a byte, that is, 1Byte=8bit, is the 1:8 correspondence. So 1MB/s equals 8Mb/s. Therefore, when writing units, we must pay attention to the case of the B letter. At this time, the size of the B letter can really be called a mistake.

The above is all the contents of the article "what are the units of measurement used to measure the transmission rate of computer external devices?" Thank you for reading! I believe we all have a certain understanding, hope to share the content to help you, if you want to learn more knowledge, welcome to follow the industry information channel!
