About these units
Megabyte (MB). A megabyte is 1,000 kilobytes, or one million bytes. Photos, songs and PDF documents typically range from one to ten megabytes.
Byte (B). A byte is 8 bits and holds a single text character. It is the base unit for measuring digital information, from file sizes to memory capacity.
