You may have noticed that the dhcp request that phil-f¢s imac sends is a broadcast packet, sent to ethernet address: ff: ff: ff: ff: ff: ff, and ip address: 255.255.255.255. but when his imac sends the dhcp request it has already selected an ip address and it knows which server the selected offer came from. why does it send the request as a broadcast packet? a. this way all dhcp servers on the network will get a copy of it, so they can withdraw other offers that were not selected. b. all dhcp servers must get a copy of the request so they can update their mappingsc. dhcp is a distributed protocol and the broadcast packets ensures that servers are synchronizedd. there is a mistake in the implementation; the dhcp request should be a unicast packet.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
