Digitizer: A digitizer is a device that is used to convert analog data into digital form or, simply put, a series of dots that can be read by a computer, stored, and later manipulated using appropriate software.
A program that performs lexical analysis may be called a lexer, tokenizer, or scanner (though scanner is also used to refer to the first stage of a lexer). Such a lexer is generally combined with a parser, which together analyze the syntax of programming languages, web pages, and so forth.he lexical analyzer (either generated automatically by a tool like lex, or hand-crafted) reads in a stream of characters, identifies the lexemes in the stream, and categorizes them into tokens. This is called tokenizing. If the lexer finds an invalid token, it will report an error.
