There is no universal agreement as to the exact definition or boundaries of logic

However, the scope of logic (broadly construed) includes:

The classification of arguments. The systematic analysis of logical forms. The systematic study of the validity of deductive inferences. The strength of inductive inferences. The study of faulty arguments, such as fallacies. The study of logical paradoxes. The study of syntax and semantics of formal languages. The study of the concepts of meaning, denotation and truth.
