If a process is moving from RUNNING -> DATABUS, does it immediately start its data transfer (if the databus is vacant)? Based on the clarifications it seemed to me that the process will wait in the DATABUS until the CPU becomes idle (after finishing any remaining processes in the ready queue) before commencing I/O. However, the sample solution seems to suggest otherwise? Perhaps this is just my misunderstanding! Any clarification would be brilliant!
