'''Accessibility''' is the degree to which a product, device, service, or environment is available to as many people as possible. Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept is often used to focus on people with disabilities or special needs and their right of access to entities, often through use of assistive technology.<section begin="lead" /> Accessibility is not to be confused with [[usability]] which is the extent to which a product (e.g., device, service, environment) can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use. | '''Accessibility''' is the degree to which a product, device, service, or environment is available to as many people as possible.

* Technology - Technology is an extremely valuable way to increase inclusion for people with a range of disabilities. Augmentative communication devices and screen readers that "speak" what is on the computer screen are examples of personal technology used by individuals with disabilities to increase accessibility and inclusion. Remember that technology access does not always mean complex electronic devices; it can be as simple as a rubber pen grip. Technology access also requires that computers, Web sites, and telephone systems are all accessible to and useable by people with a range of disabilities including visual, hearing, mobility, and cognitive disabilities. Also see [[#Web Accessibility|Web Accessibility]] below. | * Technology - Technology is an extremely valuable way to increase inclusion for people with a range of disabilities.

The {{W|Web Content Accessibility Guidelines}} ('''WCAG''') are part of a series of [[web accessibility]] guidelines published by the {{W|Web Accessibility Initiative}} (WAI) of the {{W|World Wide Web Consortium}} (W3C), the main international standards organization for the Internet. They are a set of guidelines that specify how to make content accessible, primarily for people with [[disabilities]]—but also for all user agents, including highly limited devices, such as mobile phones. The current version, WCAG 2.0, was published in December 2008 and became an [[International Organization for Standardization|ISO]] standard, ISO/IEC 40500:2012 in October 2012. | The {{W|Web Content Accessibility Guidelines}} ('''WCAG''') are part of a series of [[web accessibility]] guidelines published by the {{W|Web Accessibility Initiative}} (WAI) of the {{W|World Wide Web Consortium}} (W3C), the main international standards organization for the Internet.
