We know whether the network file or broadband bandwidth or mobile Internet traffic, its units are m (trillion), a lot of friends mobile phone general selection of 5 yuan packet 30M flow, the general Internet chat QQ, browsing some mobile Web pages are enough. So there are a lot of rookie friends often ask small 1M equals how many KB or 1M how big?
The so-called KB MB GB is the unit of memory size
They all have B, so first say B, B is a computer storage of the basic unit (byte), 1 English characters is 1 bytes, that is, 1b,1 Chinese characters to 2 characters, that is, 2B.
Then again K, Mathematics learned, K is thousand meaning, KB is 1000 bytes, but the computer operation and mathematics is different, is 1024 bytes 1KB, so said 1024B=1KB
Again M, M is the meaning of the trillion, the operation is similar to 1024 into a bit, that is to say 1024KB=1MB
Then G, and so on, 1024 MB = 1 GB
Sum up:
1g=1024m
1m=1024k
1k=1024b (bytes)
Larger than GB units have TB, PB, EB, ZB, YB, etc., TB because the capacity has been quite large, generally in the computer rarely encountered.
As for the rookie friend asked small knitting, 1M in the end how big, in fact, this is a relative concept, such as we pull the broadband to reach 4M or higher, then the speed will be very good, so we can say that 4M for home broadband is already very good, at least on the internet to see High-definition movies will not card, you can run all kinds of network applications smoothly; But if it's a computer software size of 4M, then we will certainly say that is a very small software, because the current universal software size is dozens of to hundreds of M, even a few g, so relative to the size of software 4M, is really small, so I would like to say that 1M is the relative concept of how big.
About 1M equals how many KB? I believe you can casually say is 1024KB, in fact very simple, just a concept, this article is suitable for beginners to read, Master Drift.
