1Mbps is theoretically equal to 0.125MB/s. Mbps is a unit of transmission rate, which refers to the number of bits (bits) transmitted per second; 1Mbps represents the transmission of 1,000,000 bits (bits) per second, that is, the amount of data transmitted per second is "1000000/8=125000Byte/s", converted into The commonly used MB unit is "100Mbps=100/8=12.5MB/s", that is, "1Mbps=1/8=0.125MB/s".
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
1Mbps is theoretically equal to 0.125MB/s.
Mbps unit introduction
Mbps is the abbreviation of megabits per second, which is a transmission rate unit that refers to the number of transmissions per second. Number of bits (bits). 1Mbps represents the transmission of 1,000,000 bits per second, that is, the amount of data transmitted per second is: 1,000,000/8=125,000Byte/s.
1Mbps represents the transmission of 1,000,000 bits per second, that is, the transmission of 1,000,000/8= 125,000 bytes per second
The unit of data transmission rate, letter b ( bit) represents a bit, the letter B (Byte) is a byte, and the corresponding MBPS has two explanations,
are:
Millions per second One byte (MEGABYTE);
Millions of bits per second (MEGABIT). Mbps usually refers to the second million bits per second, which is one million bits per second. 1Byte=8bit
Since in the transmission process, in order to ensure the correctness of information transmission, it is necessary to add a Ding code and a check code between each byte of transmission, so if converted to our The commonly used MB unit needs to be divided by 8, as follows:
100Mbps=100/8=12.5MB/s
4Mbps=4/8(MB/s)=0.5MB/s
Common examples:
General motherboards can only provide 100Mbps interface
SATA II hard disk can theoretically reach a speed of 3000Mbps
Converted into the commonly used MB unit is
100Mbps=100/8=12.5MB/s 3000Mbps=3000/8=375MB/s
In this way, you can see the transmission speed unit suitable for daily habits.
During the network transmission process, information also needs to be packaged and control signals such as Ethernet Header, IP Header, TCP Header, ATM Header, etc. need to be added, so some discounts are needed, but the simplest estimation method is divided by 10 That's it.
Conversion between Mbps and MB/s
MB/s means megabytes per second, which refers to the number of bytes transmitted per second (Capital B stands for Byte)
Under Windows 7 system 1Mbps=1,000,000 bits/second=1,000,000/1,024/1,024/8≈0.119MB/s
Old JEDEC standard used in Windows 7 system (It is also an old habit in the computer storage industry) The agreement is as follows:
1KB=1,024Bytes
1MB=1,024KB=1,048,576Bytes
1GB=1,024MB=1,048,576KB=1,073,741,824Bytes
1TB=1,024GB=1,048,576MB=1,073,741,824KB=1,099,511,627,776Bytes
For the ISO/IEC80000 international standard, the conversion is as follows:
1Mbps=1,000,000 bits/second=125,000 bytes/second=0.125MB/s
ISO/IEC80000 -13:2008 The standard stipulates as follows:
1KB=1,000Bytes
1MB=1,000KB=1,000,000Bytes
1GB=1,000MB=1,000,000KB=1,000,000,000Bytes
