Data storage - is a process when information (not physical objects) storages on storage objects, like CD, Hardware, or Cloud. Storage can be both physical and virtual. The base unit for the measurement of information is a bit (binary digit). 1 bit of information - a symbol or signal that can take two values: on or off, yes or no, high or low, charged or uncharged; in binary it is 1 (one) or 0 (zero). But in modern times more often-used units like megabyte, gigabyte, and terabyte.
