B indicates that one byte consists of eight bits.
B indicates that bits represent a binary (0 or 1)

A friend who has been on the Internet may have heard of the word "network bandwidth". But what is the unit of network bandwidth? Why do some people say kbps, while others say kb/s, what does it mean? Today, we will help you understand the relationships here.

For example, we use China Telecom ADSL to apply for Internet access through China Telecom. Our staff will tell us that the requested ADSL bandwidth is 1 Mbps, and the 1 Mbps here refers to "1 Mbps ", it refers to the digital signal transmission rate, that is, the network bandwidth.

We know that in a computer, 1 m = 1024 K, the above 1 Mbps = 1024 kbps refers to the number of kilobytes of information transmitted per second (k indicates the number of kilobytes, KB indicates the number of thousands of locations, and PS indicates per second. Generally, the company uses KB (note that it is a lowercase B) to indicate network bandwidth.

In practice, we often find that the network transmission speed is expressed in KB (note that it is capital B). For example, we use thunder to download a plug-in, in the speed column, we often see kb/s. What is the problem? That is because we usually use bytes to indicate the file size, because if the bit is used to indicate the file size, the number is too large and hard to remember, so it is expressed in bytes. The size of the file transmitted over the network in one second is 1 kb = 8 KB. The bandwidth is 1 kb/s = 8 kbps.

To sum up, the actual unit conversion of China Telecom's ADSL network bandwidth of 1 MB is1 Mbps/S = 1024 kbps/S = 1024kb Bytes 8/S = 128kb/s,That is to say, your ADSL can be 1 Mbps or kb/s, which means the same. (Some beginners may ask, my ADSL clearly says that the bandwidth is 1 Mbps. How can I download more than 100 kb/s now? In fact, you can calculate that your bandwidth is about to reach 1 Mbit/s)

I don't know if my statement is clear. In fact, I need to pay attention to the Case sensitivity of the letter B. If it is lowercase B, it indicates a bit. If it is capital B, it indicates bytes. 1B = 8B. So the next time you want to ask people about the network bandwidth, you have to know whether it is big B or Small B, otherwise it is easy to get confused.
