A digital device that accepts input, processes data into information, stores data, and provides output is a

• A. Computer
• B. Router
• C. Printer
• D. Switch

Answer: (A)

A computer combines input, processing, storage, and output to turn raw data into usable information. It can take input from devices like a keyboard or mouse, use its processor to perform calculations and run programs (turning data into meaningful information), store data on memory or storage devices, and present results through outputs like a monitor or printer. That's why this option is the best fit.

The other devices don’t perform all four roles together. A router moves data between networks and may make decisions about where to send packets, but it isn’t designed to process arbitrary data into information for a user or to store user data long-term. A printer primarily provides output—it does not process data into information or provide general storage. A switch forwards data within a local network and also doesn’t perform broad processing or storage for end-user information.
