The Free On-line Dictionary of Computing (30 December 2018):
A temporary memory area, used to transfer
information within a document being edited or between
documents or between programs. The fundamental operations are
"cut" which moves data from a document to the clipboard,
"copy" which copies it to the clipboard, and "paste" which
inserts the clipboard contents into the current document in
place of the current selection.
Different Graphical User Interfaces vary in how they handle
the different types of data which a user might want to
transfer via the clipboard, some (e.g. the X Window System)
support only plain text, others (e.g. NEXTSTEP) support
arbitrarily typed data such as images.
