(1) A place from which data is taken. Many computer commands involve moving data. The place from which the data is moved is called the source, whereas the place it is moved to is called the destination or target. If you copy a file from one directory to another, for example, you copy it from the source directory to the destination directory. The source and destination can be files, directories, or devices (that is, printers or storage devices).

(2) The node on a network from which data is sent to its destination.
