n.
Powerful computer programming language designed for manipulating lists of data or symbols rather than processing numerical data, used extensively in artificial-intelligence applications.
It was developed in the late 1950s and early 1960s by a group headed by John McCarthy at MIT. Its name derives from "list processor." Radically different from such other programming languages as ALGOL , C , C++ , FORTRAN , and Pascal , it requires large memory space and is slow in executing programs.
