recognize keyword and identifiers for example counter = counter + increment becomes id = id + id /*check if id is a keyword*/ We often use the terms "token", "pattern" and "lexeme" while studying lexical analysis.

We assume that we have a specification of lexical analyzers in the form of regular expression and the corresponding action parameters. Action parameter is the program segment that is to be executed whenever a lexeme matched by regular expressions is found in the input.

For example, lex is a popular tool for lexical analysis, yacc is a popular tool for syntactic analysis. Similarly, tools have been designed for each of these stages that take in specifications required for that phase e.g., the code generator tool takes in machine specifications and outputs the final compiler code.
