Lexical analysis helps the interactivity and visualization for active learning that can improve difficult concepts in automata. This study gives a view on different lexical analyzer generators that has been implemented for different purposes in finite automata. It also intends to give a general idea on the lexical analyzer process, which will cover the automata model that is used in the various reviews. Some concepts that will be described are finite automata model, regular expression and other related components. Also, the advantages and disadvantages of lexical analyzer will be discussed.
