A collection of compatible digital components make up a ________?

• A. Logic family
• B. Circuit
• C. Module
• D. Processor

Answer: (A)

The idea being tested is that digital components are organized into a logic family, a group of devices that share common electrical characteristics and interface conventions. Components from the same logic family use compatible voltage levels, timing, drive currents, and input/output styles, so they can be connected together reliably on the same board. Mixing devices from different families can cause logic levels to be mismatched and operation to become unpredictable, even if each device works fine on its own. A circuit is just a particular interconnection of components, not the grouping itself. A module is a self-contained unit or subsystem, and a processor is a specific type of device, not the general collection of compatible digital parts. Hence, a collection of compatible digital components makes up a logic family.
