Clipboard, in relation to computers, a special memory resource maintained by operating systems such as the Apple Macintosh operating system, Microsoft Windows, and the OS/2 Presentation Manager. A clipboard stores a copy of the last information that was “copied” or “cut.” A “paste” operation passes data from the clipboard to the current program. A clipboard allows information to be transferred from one program to another, provided the second program can read data generated by the first. Data copied using the clipboard is static and will not reflect later changes.
