What is a Megabyte?
The megabyte equals 1,024 kilobytes (1,048,576 bytes) in binary computing conventions, or 1,000,000 bytes in decimal SI conventions. It is the common unit for document files, compressed images, and small application installers. A high-quality JPEG photograph typically occupies 3–8 MB. A standard CD-ROM holds 700 MB of data.
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.
