K is the abbreviation of KILO, which stands for 1000 in mathematics, but stands for 1024 in computer binary.

MB is written in megabytes, which means one million bytes. Similarly, because it is binary, the representative value of MB is 1024K K. For convenience, it is customary to say that 1MB can store10 million bytes.

Speaking of which, let's say an easy-to-remember example. Friend, in fact, a K can record 5 12 Chinese characters, and a MB can record more than 5 10000 Chinese characters. In actual use, there are still some things in the format that take up space, so it is less than the above.
