The digital divide is unequal access to and effective use of digital technology, encompassing four interrelated dimensions: motivational, material, skills, and usage access.
The digital divide worsens inequality around access to information and resources. In the Information Age, people without access to the Internet and other technology are at a disadvantage, for they are less able to connect with others, find and apply for jobs, shop, and learn.
Accessibility is the design of products, devices, services, vehicles, or environments to be usable by disabled people. The concept of accessible design and practice of accessible developments ensures both "direct access" (i.e. unassisted) and "indirect access" meaning compatibility with a person's assistive technology (for example, computer screen readers).
Accessibility can be viewed as the "ability to access" and benefit from some system or entity. The concept focuses on enabling access for people with disabilities, or enabling access through the use of assistive technology; however, research and development in accessibility brings benefits to everyone. Therefore, an accessible society should eliminate digital divide or knowledge divide.
