The system bus cannot be shared by the main memory, the CPU, and the input/output devices. Choose one: Is it accurate or erroneous?

Imagine that you have been given the responsibility of illustrating how the Memory Module, the I/O Module, and the CPU Module connect with each other and the rest of the computer. Do you feel that it is vital for you to highlight this message in an appropriate manner?

Do you prefer a synchronous or an asynchronous bus when working with a computer's central processing unit and main memory?What time does the bus stop running, if at all? Explain.

Should we connect the central processor unit to the memory via an asynchronous bus or a synchronous bus? Could you elaborate on your response in any way?
