1. What circuit do asynchronous buses lack?

2. Are there fixed time periods in a bus transaction in an asychronous bus?

3. What does MSYN stand for?

4. What does MSYN do?

5. When the responder is done with its work, what wire does it assert?

6. If there is no timing in an asynchronous bus, how do the components coordinate their work?

7. In the following picture of a read transaction, identify the major events with a black dot on the appropriate signal line. Then interconnect the events with arrows to indicate the ordering.

8. Which tends to be faster in completing bus transactions?
