A kiosk in computing is an interactive terminal that provides access to information and applications for communication, commerce, entertainment, or education. It is a computer with specialized hardware and software that is integrated into a housing unit. Kiosks are used to make interactions with computers more accessible and user-friendly. There are different types of kiosks, including:

• Internet kiosks: These are terminals that provide public Internet access. They are typically placed in settings such as hotel lobbies, long-term care facilities, medical waiting rooms, apartment complex offices, or airports for fast access to e-mail or web pages. Internet kiosks sometimes have a bill acceptor or a credit card swipe, and nearly always have a computer keyboard, a mouse, and a monitor.

• Self-service kiosks: These are unattended self-service booths with computers that dispense information or make sales via a touchscreen. They are used for a variety of purposes, such as ticketing, ordering food, or checking in for a flight.

• Kiosk mode: This is a Windows operating system feature that only allows one application to run. Kiosk mode is a common way to lock down a Windows device when that device is used for a specific task or used in a public setting. For example, kiosk mode can lock down a point-of-sale (POS) application to prevent customers or employees from tabbing out of the application and browsing other apps, closing important tools, or otherwise disrupting the intended use of the computer.

Kiosk computers are used to access different aspects of a computer such as information or software. They are deployed widely across all industry verticals and are considered "Kiosk Hardware" within the kiosk industry.
