The Instruction Fetch is implemented in the text with first 4 states and then three. What would have to be done to the datapath to make it two states long?
What will be an ideal response?
In order to implement the Instruction Fetch in 2 states, there would have to be a second bus incorporated into the datapath, that could either take the MEM[MAR] to the IR in the first state, or could take A+1 to the PC in the second state, therefore combining 2 of the present states into 1, eliminating 1 state overall.

Any client using the ntp service must communicate with it by means of messages passed over a communication channel. If a bound can be set on the time to transmit a message over a communication channel, then the difference between the client’s clock and the value supplied by the ntp service would also be bounded. With unbounded message transmission time, clock differences are necessarily unbounded. Consider two communication services for use in asynchronous distributed systems. In service A, messages may be lost, duplicated or delayed and checksums apply only to headers. In service B, messages may be lost. delayed or delivered too fast for the recipient to handle them, but those that are delivered arrive order and with the correct contents.
Describe the classes of failure exhibited by each service. Classify their failures according to their effect on the properties of validity and integrity. Can service B be described as a reliable communication service?
