A mobile hinged computer with an integrated keyboard that uses a full operating system is called a

• A. Tablet
• B. Smartphone
• C. Desktop
• D. Laptop

Answer: (D)

Think about the design and how it’s meant to be used: a single portable unit with a screen and a keyboard connected by a hinge, so you can open it like a book and carry it around, while running a full desktop-style operating system. That’s what a laptop is. It’s built to be portable, and the keyboard is integrated into the body, not just an attachable accessory. A tablet, while portable, is mainly touch-centric and often relies on a mobile OS; even when you add a keyboard, it’s usually not integrated into the device in the same clamshell way. A smartphone is smaller, sticks to mobile typing and apps, and isn’t designed with a built-in keyboard in a hinged, laptop-like form. A desktop stays in one place and isn’t portable. So the described device is a laptop.
