Which statement best describes a very small computing device usually based on a wireless phone or pager?

• A. A desktop computer without memory.
• B. A very small device, usually based on a wireless phone or pager, that can perform a limited amount of computing.
• C. A digital camera only.
• D. A mainframe computer.

Answer: (D)

Think of a handheld, portable computer that stays connected wirelessly. This kind of device is small enough to fit in your hand and can run simple apps, check messages, browse the web, and perform light computing tasks. It’s rooted in mobile technology, usually based on a wireless phone or pager, which is why it’s described as a very small device that can perform a limited amount of computing. The other descriptions don’t fit: a desktop computer is large and stationary with more resources than a handheld device implies; a digital camera may process images but isn’t intended as a general-purpose computing device; a mainframe is a large, centralized system, not something portable or small.
