What is meant by the term "accessible rich internet applications" (ARIA)?

The term "accessible rich internet applications" (ARIA) refers specifically to a set of specifications aimed at enhancing the accessibility of web content and applications. This is crucial because many web applications that use dynamic content and advanced user interface controls (like those created with JavaScript) can pose barriers to users with disabilities. ARIA provides developers with additional markup that can be used to improve communication between assistive technologies (like screen readers) and the web application. By implementing ARIA attributes, developers can semantically convey roles, states, and properties of the elements within their applications, thus ensuring a more inclusive experience for users with disabilities.

The correct answer emphasizes ARIA's role as a standard that directly contributes to making internet applications more accessible, enhancing user interaction and engagement for all users, including those with disabilities.
