Storage first you have to be familiar with the computing unit of storage:
This is the basis of the university curriculum computer learning computer storage units such as the KB, MB, GB, and so on to represent the storage units.
Here's what you need to know about conversions between your units:
The unit and conversion relationships are as follows:
The smallest storage unit is bit (BITS) and the computer's binary number value is 0 or 1;
Byte Byte:8 bits is a byte (B), the base unit.
Up to a large level is KB 1kb=1024b
1MB =1024kb is usually said "trillion" especially reminds of this storage "trillion" and the network bandwidth "trillion" is not a meaning, units are different, here to explain the size of the file (Mega) is a byte (similar to the size of a USB flash drive), the network (trillion) unit is bps and bits per second (it refers to the rate), the network we often encounter 1000MB file bandwidth is 1000Mbps transmission is not only need 1S to complete, this is certainly not 1b=8b, ideal time is divided by 8来 conversion, but almost not to the ideal state.
1GB =1024MB
1tb=1024gb
Compute example: A hard disk with a nominal size of 100GB, with an actual capacity of 100x1000x1000x1000 bytes/1024X1024X1024≈93.1GB
