What device does a computer process information on?Central Processing Unit (CPU)
The CPU is the brain of a computer, containing all the circuitry needed to process input, store data, and output results. The CPU is constantly following instructions of computer programs that tell it which data to process and how to process it.
What devices get processed information out of a computer?An output device is any peripheral that receives data from a computer, usually for display, projection, or physical reproduction. ... Monitors and printers are two of the most common output devices used with a computer.
