2Explain the difference between proprietary and open standards(2)
- AThe difference between proprietary and open standards is proprietary standards are owned by a company and handle data in a certain way, communicate with the operating system in defined ways and work with a defined interface, where as, open standards are publicly available and can be modified by users
