Acceptance testing and accessibility testing

Hi… let me know what is the difference between acceptance testing and accessibility tesing. I have read about it but am unable to understand the concept hence would request an elaborate information on this.

Acceptance Testing (AT) is conducted by internal users (of the company providing the product) to ensure that the product meets customer requirements by use of scenario testing or "use-cases". It is distinct from QA testing because instead of validating technical specifications, it is validating business requirements.

User Acceptance Testing (UAT) is conducted by the end user/customer to ensure that the product meets their business needs and the application works as they intended. It is distinct from AT because it is performed from a customer perspective, and instead of validating business requirements, it is validating real world business scenarios and business needs, that the product providers cannot truly reproduce.
