The next two storage units are described: Bits, bytes

Bit: "Bit" is the smallest unit of data in an electronic computer. The status of each bit can only be 0 or 1.

Word: "word" consists of a number of bytes, the number of bits is called word length, different grades of machines have different length of words. For example, a 8-bit machine, its 1 characters equals 1 bytes, and the word length is 8 bits.

KB: is 1024 bytes

MB: Is 1024 kb

GB: is 1024 MB

TB: is 1024 GB

。。。。。

However, most mobile phones say how many GB is generally calculated according to the size of 1000MB.
