Explanation:
Detailed explanation-1: -A Token is a syntactic category that forms a class of lexemes. These are the “nouns", “verbs", and other parts of speech for the programming language. In a practical programming language, there are a very large number of lexemes, perhaps even an infinite number.
Detailed explanation-2: -In computer science, lexical analysis, lexing or tokenization is the process of converting a sequence of characters (such as in a computer program or web page) into a sequence of lexical tokens (strings with an assigned and thus identified meaning).
