Accessibility refers to the degree to which a product, environment, service, or information is available and usable by people with disabilities. Accessibility aims to ensure that everyone, regardless of their abilities, has equal access to participate in society without barriers or discrimination.This includes physical accessibility, such as making buildings or spaces easier to navigate for wheelchair users, as well as digital accessibility, such as creating websites and apps that people with visual, auditory, or motor impairments can easily use.
