lexical analysis
<programming> (Or "linear analysis", "scanning") The first
stage of processing a language. The stream of characters
making up the source program or other input is read one at a
time and grouped into lexemes (or "tokens") - word-like
pieces such as keywords, identifiers, literals and
punctutation. The lexemes are then passed to the parser.

Lexical analysis
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). A program that performs lexical analysis may be termed a lexer, tokenizer, or scanner, although scanner is also a term for the first stage of a lexer.

Lexical analysis
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). A program that performs lexical analysis may be termed a lexer, tokenizer, or scanner, although scanner is also a term for the first stage of a lexer. A lexer is generally combined with a parser, which together analyze the syntax of programming languages, web pages, and so forth.
