What is a characteristic of a protocol defined by an open standard compared to proprietary protocols?

A characteristic of a protocol defined by an open standard is that it promotes public access and collaboration. Open standards are designed to be publicly available, allowing anyone to implement, improve upon, and contribute to the protocol without needing permission from a controlling entity. This approach encourages innovation and interoperability among different systems and products, as developers can build compatible solutions that work with a wide range of services and devices. The collaborative nature of open standards fosters a community of users and developers who can share ideas, identify issues, and propose enhancements, making technology more accessible and adaptable.

In contrast, proprietary protocols tend to be controlled by a single company or organization, which restricts their modification and access, and often requires licensing fees for their use. These characteristics limit collaboration and public involvement, leading to potential vendor lock-in and a lack of compatibility with other systems.
