When you are typing it will insert text by pushing any existing text over rather than replacing them which happens in overtype mode. You can turn Insert mode on by pressing the Insert key, and by pressing it again it will turn it off.
Insert in terms of the menu or tab on the ribbon, allows you to insert various things, like pictures, fields, dates, charts etc. Insert in terms of the typing mode will push text ahead of itself if you are typing in the middle of a word or sentence. The opposite is overtype which will replace what you have already as you type. Usually people work in Insert mode.
