A Terms of Use Agreement is the contract between the owner of a service or even an intellectual property which sets forth how the service might be legally used. Many times they are found on websites and describe the rules and terms for using the site including what may or may not be done on the site or with the material. Terms of use can also apply to written works and other artistic works like pictures or music.
Terms of Use will generally describe the service, limit liability, cover indemnification, contain various disclaimers and specify the governing law.
