A checksum is a small-size datum used for the purpose of detecting errors which may have been introduced during a data file transmission or storage.
The actual procedure which yields the checksum, given a data input is called a checksum algorithm. A good checksum algorithm will usually output a significantly different value, even for small changes made to the input.
Checksum tools are installed on Mac and Linux by default. A Windows version of a checksum program is available at https://raylin.wordpress.com/downloads/md5-sha-1-checksum-utility/
