Devices that integrate the computer case into the monitor, but have an external keyboard and mouse are called computers

• A. All-in-one
• B. Desktop
• C. Laptop
• D. Mainframe

Answer: (A)

All-in-one devices place the computer’s processing hardware inside the same unit as the display, forming a single integrated box. Since the CPU, memory, and other components are built into the monitor housing, you don’t have a separate computer tower; you just connect an external keyboard and mouse. This setup matches the description given in the question.

A desktop usually has two distinct parts: the monitor and a separate desktop tower containing the CPU. A laptop has the keyboard and pointing device built into a portable, single unit. A mainframe is a large, centralized computing system used in enterprise environments.

So, the best term for a device where the case is integrated into the monitor, with external keyboard and mouse, is all-in-one.
