1.	Explain How Timing Differences Are Smoothed Out Among Processors, Memories And I/o Devices.
Answer» The devices connected to a bus vary widely in their speed of operation. Electro mechanical devices such as key board and printers are RELATIVELY slow. Others like magnetic or optical DISKS, are considerably faster. Memory and processor units operate at electronic speeds. A common approach to smooth out the timing differences is to include buffer registers with the devices to hold the information during transfers. They prevent a high speed processor from being locked to a slow I/O device during a sequence of data transfers. This allows the processor to SWITCH rapidly from one device to another, interweaving its process activity with data transfers involving SEVERAL I/O devices. Thus, buffer registers smooth out timing differences among processors, memories and I/O devices.
