What is the Full Form of LISP ?

LISP - LISt Processing

Lisp is the second-oldest high-level programming language (after Fortran), originally appeared in 1958. The language was designed by John McCarthy at Massachusetts Institute of Technology (MIT).

The language was designed for easy manipulation of data strings, and continues to be popular in the field of artificial intelligence till now. Its computational capability with symbolic expressions rather than numbers makes it convenient for artificial intelligence applications.

Linked Lists are one of the major data structures of Lisp languages, whereas the source code is itself made up of lists. A LISP program may be written as a list with the function name first followed by the list of argument.
For example: A function x that takes 2 arguments might be written as,
(x arg1 arg2).
