In computer science a string is any finite sequence of characters (i.e., letters, numerals, symbols and punctuation marks)..

Kolmogorov randomness defines a string (usually of bits) as being random if and only if any computer program that can produce that string is at least as long as the string itself. They are less useful when storing information for the computer to use. A character is one single unit of a text or character string, where the individual characters and the entire string are manipulated in various ways by code functions and displayed in object-oriented programming (OOP) through controls such as text boxes and drop-down lists.
