Full Answer

Computers use a base-2 system, which is why they measure a gigabyte as 1,024 megabytes instead of 1,000. One bit is the minimum amount of data, representing one signal of "on" or "off." One byte is the same as 8 bits, and one letter in a text document is 1 byte of data. One kilobyte of data is 1,024 bytes, 1 megabyte of data is 1,024 kilobytes and 1 gigabyte is 1,024 megabytes. The system goes on to terabyte, petabyte, exabyte, zettabyte and yottabyte, with each unit being 1,024 of the previous unit.
