CRC-16 is a broad family of CRC (cyclic redundancy check) algorithms that produce a 16-bit result.
Refer to the CRC article for more information.

[edit] Specific algorithms
Selected CRC-16 algorithms are listed here. The names are from the CRC RevEng Catalogue.
[edit] CRC-16/ARC
Also referred to as CRC-16-IBM.
The CRC of ASCII "123456789" is 0xbb3d.
Used by ARC, LHA, StuffIt, Zoo, ArcFS, Spark.
[edit] CRC-16/XMODEM
This is a form of CRC-16-CCITT, though it may be inaccurate to refer to it by that name.
The CRC of ASCII "123456789" is 0x31c3.
Used by MacBinary, BinHex, LBR.
[edit] CRC-16/IBM-3740
Same as CRC-16/XMODEM, except that it is initialized to 0xffff instead of 0x0000.
