The _______ is a system of wires and software than connects sensors and computers.

• A. CANbus
• B. LINbus
• C. USBlink
• D. CAN Network

Answer: (A)

The CANbus is the vehicle’s backbone for in-vehicle communication. It’s a system of wires (a two-wire twisted pair) and software that lets multiple sensors and control units talk to each other without a central computer. This setup enables different modules—like engine, transmission, airbag, and body control modules—to send and receive messages efficiently, with built-in priorities and fault tolerance. That makes it the best fit for the description.

LINbus exists as a simpler, single-wire network used for less critical subsystems, so it’s not the primary backbone described. USBlink isn’t a standard automotive bus. CAN Network is a general term for the network, but the established name for this automotive backbone is CANbus.
