Open standard is a term widely used in the technology industry and refers to a set of criteria or guidelines that are openly accessible and available to the public. There are many synonyms for this term, including open protocol, open technology, open architecture, and open format. These terms all relate to open source software and hardware, which allows for collaboration and transparency among developers, manufacturers, and users.
