What is the difference between Mbps, Mb/s, MB/s, Gbps, GB/s?
As you may have noticed in daily life, when new mobile phone products are released and telecom operators are promoting network speeds, their speed units are all used in Mbps. We usually refer to 50 megabytes and 100 megabytes of home broadband. It is also Mbps.
But when using U disk or hard disk to copy files, the speed unit displays "MB/s". In the real-time display of the network speed at the top of our mobile phone, the unit is also MB/s. So, what is the difference between Mbps and MB/s?
The following is a detailed introduction. What is the difference between Mbps, Mb/s and MB/s?
1. Mbps, its full name is Million bits per second (1,000,000bit/s), which means that one million bits of data are transmitted per second
2.The bit here is the smallest unit representing digital signal data. Corresponding to a digital information of the binary number, the value of the bit will only be 0 or 1
Mb/s
1. Mb in Mb/s has the same meaning as Mb in Mbps, both represent millions of bits, so Mbps=Mb/s
MB/s
1. MB here means Million Bytes, and the files in the computer are expressed in Bytes
2. Byte is a unit of measurement used by computers to measure storage capacity. A binary number string is used as a combination, which is a small unit. The most commonly used byte is an eight-bit byte, that is, it contains an eight-bit binary number. One bit represents 0 or 1 (that is, binary), and every 8 bits form a Byte (abbreviated as B)
Then we can clearly know the relationship between bit and byte:
1. 1Byte=8bit
2. When using Bytes/s and bits/s to express the network speed, there is 1MB/s=8Mbps=8Mb/s
3. For example, the theoretical rate of the current 5G network is 10Gbps, which corresponds to: 10÷8=1.25GB/s Why is Mbps generally used to express network speed?
When telecom operators advertise, Mbps is the most correct unit of network rate, because telecom operators are calculated according to bits when charging, so the network speed is generally expressed in bits/s
Byte only makes sense when it means data storage, because the digital signal in transmission is not necessarily measured according to 8bit as a group
Whether it is Byte or bit as the network speed unit is actually correct, but we must pay attention to the capitalization of the B letter when writing the unit!
Gbps
Gbps, also known as switching bandwidth, is a unit to measure the total data exchange capacity of the switch, and the transmission speed is 1000 Megabits per second (1 Gbps).
The rate unit of Huawei's 5G network boycotted by the US government is Gbps. Its maximum theoretical rate is 10Gbps
Now the 5G network test rate can basically reach 900+Mbps (0.88Gbps), and some can even reach 1.1Gbps.
For example:
■ USB 3.1 GEN2 transmission speed 10 Gbps = 10×1024÷8 = 1280 MB/s
(1280 MB/s is just a theoretical value. In fact, when transmission speed exceeding 700MB/s can be regarded as a GEN2 cable)
■ USB 3.1 GEN1 transmission speed 5 Gbit/s = 5×1024÷8 = 640 MB/s
