What does the computer memory G unit mean?

Gigabyte (GB, also called gigabyte or gigabyte or number in China), often abbreviated as G, is the decimal unit of information measurement. Gigabytes are often easily confused with gigabytes, the binary unit of information measurement. It is often used to indicate the storage capacity of mass storage media such as hard disk and memory.

The gigabyte here is different from the "GB" that we often say, but it is actually "GiB" (because Windows misuses GB, so "1GB" displayed in Windows should actually mean "1GB", but Windows displays it as "1GB", which often causes misunderstanding. )

Actually1GB =1000 MB =1000000 KB =100000000 B.

Unlike,1gib =1024mib =1048576kib =1073741824b (this is not ib).

However, the conversion between them is different, which often leads to confusion. For example, general hard disk manufacturers adopt the basic system of 1 0,000,000 000( 10/0) bytes = 1GB, while the conversion formula in Microsoft Windows operating system is1GB =10,073,7466. However, in Apple's OS X operating system, the capacity of storage devices is calculated in the decimal system of 1GB = 1 0,000,000,000 () bytes, which avoids the trouble in calculation and use.
