4. The types of access method in memory systems are: access time, cycle time, and transfer rate.? 5-For the multiple zoned recording system, the surface of disk is divided into a number of tracks and each track have the constant number of bits.? 6. The timing of the bus is: synchronous and asynchronous, in the synchronous timing all devices tied to a fixed clock rate but in asynchronous the events on a bus follow and depend on the occurrence of previous events.?

help me fast please
