Signed overpunch is a data representation method used primarily in older computing systems for storing numerical data, especially in the context of mainframe computers and COBOL programming. This method allows for efficient use of storage space when representing signed decimal numbers, typically in fixed-length formats. In signed overpunch, a decimal digit is stored in a character, where the last character of the string indicates the sign of the number (positive or negative).

Dispersion in optics refers to the phenomenon in which the phase velocity of a wave depends on its frequency. This effect is most commonly observed when white light passes through a prism or other transparent medium, resulting in the separation of light into its constituent colors, typically represented as a spectrum ranging from red to violet. The underlying reason for dispersion is that different wavelengths of light travel at different speeds in a medium.
