Why 2M broadband download speed is only 200 K

We often encounter such a doubt, I clearly apply for 2Mb bandwidth, but when I download the software of the local website, the download speed can only reach 200KB or so, and the telecommunications department said that my network speed is very normal. Where is the reason? In fact, this is just a small knowledge, the system home Xiaobian will explain for you: Careful readers will definitely find that the two data in my above, the unit is different, one is Mb, the other is MB. The specific difference is here. In daily writing, we often do not pay attention to the above details, and the true meaning of these two units is different. Mb (full name Mbps) This is the unit of the telecommunication department to measure network bandwidth, which means megabits per second (what is the meaning of M and K, I believe it is no longer necessary to explain), and MB (Mbytes) is the unit of computer file capacity. Megabytes. Because we ignored this small difference when we looked at the data, it caused a misunderstanding of Kb and KB. Detailed explanation of the bandwidth unit: In our memory, we are most familiar with the fact that when using Modem to access the Internet, the access speed is only 56Kbps. In this unit, bps is an abbreviation of bit Per Second, translated into Chinese is the bit per second, which means that the number of bits transmitted in one second means. So, what is the connection between bits and bytes? Detailed storage unit: One of the most common words we hear is the 250G hard drive. G is the unit of hard disk capacity and is also the unit of storage. The minimum unit of storage is byte Byte. For the storage unit, there are the following units, GB, MB and KB. Then the conversion relationship between the three is: 1GB=1024MB, 1MB=1024KB, 1KB=1024Bytes. The relationship between Kb and KB: We know in computer principle that the minimum storage unit of a computer is byte Byte, one byte, which is composed of eight bits. Thus, we can think that a byte is composed of 8 bits, or a space occupied by one byte and eight bits is the same. Therefore, when we use a 2Mb bandwidth network download, the theoretical speed should be 2048Kbps divided by 8 equals 256KB. So your download speed is about 200KB is basically normal!
