The document provides a preliminary exam for an intro to computers course. It includes 20 multiple choice questions testing knowledge of early computing devices like the abacus and Jacquard's loom as well as components of modern computers like processors, memory, and motherboards. Students are asked to identify computer ports, the phases of data processing, and specifications for processor, memory, and motherboard components.
