While in an interactive nslookup session, you'd use the keyword to change the dns server you're using.

Keyword 'server' is used to DNS Server change in an session of interactive nslookup.

Explanation:

Nslookup is a "network administration command line" tool used to know about the Domain Name System (DNS) for getting the records of different domain names. It is primarily used for troubleshooting DNS Server. We can access information on the Internet through domain names.

These names are located in the hub of Domain Name System. The web browsers on the Internet interact with each other using Internet Protocol addresses.  

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 !
