Clipboard is a continuous segment of Windows system. Memory space, which can vary with the size of information stored, is used to temporarily store and exchange information. There are many kinds of information that can be stored in windows and RAM or virtual memory when it comes.
The information saved on the clipboard when cutting or copying can be updated or cleared only when the other information is clipped or copied again, or when the power is cut off, or windows is withdrawn, or purposefully cleared. That is, once clipping or copying, the content can be pasted many times.
