Petabyte
A Pb is the unit symbol for the 'Petabyte'. A Petabyte is made up of multipleunit bytes, which stores the digital information and denotes the size of data. A byte is a size, which is made up of 8 bits. A bit is a single unit of data. It can be '0' or '1'. And, the short form of Petabyte is Pbyte.
A petabyte is equal to 10^{15} bytes or 2^{50} bytes.
1 Petabyte is equivalent to the following values:
 1024 Terabytes (Tb),
 1 million gigabytes, or
 1,000,000,000,000,000 bytes.
The size of the petabyte is slightly less than pebibyte. A petabyte is rarely used in measuring the storage capacity of devices. It is mostly used for measuring the data, which is stored in large computer networks or server farms. Like, Facebook and Google, two internet companies store more than 100 petabytes of data on their servers. Petabyte (Pb) is that unit that is larger than a terabyte (Tb) and smaller than the unit exabyte (Eb).
