Definition: Accessibility refers to the ability of a person or system to perform certain activities without any form of physical, mental, or emotional barrier that makes it difficult for them to access or use the resources necessary to do so. Accessible software typically includes applications that are designed and tested with users with disabilities in mind, making sure they can access all features and functionality without significant difficulty. Accessibility is also important because it helps ensure a better quality of life by ensuring that individuals with disabilities have equal opportunities for success and inclusion in society. For example, people who use assistive technology like screen readers, voice recognition software, or other tools to access information on the internet often find it easier to do so than those without these aids. Accessible design refers to designing products or systems in a way that is usable by everyone, regardless of their abilities or disabilities. This includes ensuring that users are aware of accessibility features and can navigate them easily, making sure that assistive technology is used effectively when necessary, and creating environments that encourage inclusivity and equal access for all stakeholders. In summary, the word "accessive" refers to the ability of a person or system to perform certain activities without any form of physical, mental, or emotional barrier that makes it difficult for them to access or use the resources necessary to do so.
