What is Petabyte?
A '''petabyte''' ('''PB''') is a [[unit of measurement]] in [[computer]]s and similar electronic [[device]]s. One petabyte holds 1000 [[terabyte]]s ('''TB''') or 1,000,000,000,000,000 [[byte]]s. Large organizations use petabytes of storage to hold massive amounts of data. To store this amount of data at home would require about 1000 large home computers. For personal use, the petabyte is extremely rare; most modern PC's and personal programs use [[terabyte]]s (primarily for very large backups), [[gigabyte]]s, [[megabyte]]s and occasionally [[kilobyte]]s. One thousand petabytes make one [[exabyte]]. There is also already petabyte [[supercomputer]]s such as Frontier and Summit. {{tech-stub}} [[Category:Units of information]]
