What is ziza byte?

Answer 1

There is no such numerical reference, but there is a zettabyte. If one gigabyte is 109 bytes or 1,000,000,000 bytes, going upward in 3rd power increments (each 3 zeros):

• terabyte = 1012 (1,000,000,000,000) bytes
• petabyte = 1015 (1,000,000,000,000,000) bytes
• exabyte = 1018 (1,000,000,000,000,000,000) bytes
• zettabyte is = 1021 (1,000,000,000,000,000,000,000) bytes
