What is a Gigabyte?
The gigabyte equals 1,024 megabytes (1,073,741,824 bytes) in binary conventions, or one billion bytes in decimal SI conventions. It is the principal unit for consumer storage: smartphones, USB drives, and most hard drives are sized in gigabytes or terabytes. A full-length HD movie in compressed format requires about 4–8 GB. The discrepancy between binary and decimal definitions means a '1 GB' drive shows as about 0.93 GB in Windows.
What is a Kilobyte?
The kilobyte equals 1,024 bytes in binary (computing) conventions, or 1,000 bytes in decimal SI conventions. The discrepancy arises because computing naturally works in powers of 2, while SI prefixes denote powers of 10. The IEC introduced 'kibibyte' (KiB = 1,024 bytes) to distinguish the two, though 'kilobyte' and 'KB' are widely used for both. A plain-text email without attachments is typically 2–5 kilobytes.
