IPA IP 2025 Question 18

Software designed so that a wide range of people, older people and people with disabilities included, can use it equally — that is accessibility in IT.

Accessibility is the extent to which people can reach and use information and functions whatever their age, disability or other characteristics. In software and websites it means, for example, working with screen readers and with the keyboard alone, enough colour contrast, text that can be enlarged, captions for audio, and never conveying information by colour alone. Guidelines such as WCAG (JIS X 8341 in Japan) set out the requirements.

Answer (a)

Why not others:

• •(b) — identifying customers from customer data and deepening relationships through channels such as call centres and the Internet is CRM (customer relationship management)
• •(c) — the feelings and responses a person gets from imagining or actually using a product, system or service are UX (user experience)
• •(d) — reliably granting and restricting privileges such as reading and updating files and databases is access control, a security measure; the similar word does not make it accessibility

Key rule: Accessibility: usable by people of every age and ability; usability: effective, efficient and satisfying use; UX: the whole experience of using it; access control: who may use which information.
