An introduction may refer to any of the following:
1. The introduction in a document, usually the first or several paragraphs, provides a brief synopsis of the document's contents. It may also provide insight as to why the document was written and its purpose. For example, our computer definition gives an introduction to a computer and then follows with further information and related information.
3. An introduction is what a person might do when first meeting someone or talking in front of a crowd. The introduction may include the speaker's name, their job title, where they live, and why they are qualified to speak on the material being presented.
