What does the MUX do?

• A. Transfers information around the MC system
• B. Converts analog to digital
• C. Provides power to the MCs
• D. Schedules tasks for MCs

Answer: (A)

A multiplexer routes one of several inputs to a single output based on a control signal, letting information be transferred through a shared path in the MC system. This is exactly how data from different subsystems can be sent over one line or bus, by selecting which signal is active at any moment. It doesn’t convert signals from analog to digital (that’s an ADC), it doesn’t provide power, and it doesn’t schedule tasks. The MUX’s role is to enable efficient data routing within the system by multiplexing inputs onto a common path.
