Explanation / Answer

45. DHT

The most common type of structured P2P networks implement a distributed hash table (DHT),in which a variant of consistent hashing is used to assign ownership of each file to a particular peer.This enables peers to search for resources on the network using a hash table: that is, (key, value) pairs are stored in the DHT and any participating node can efficiently retrieve the value associated with a given key.

44 .Use the full expressive power of object oriented programming model

RPC supports only primitive data types while RMI allows objects to be passed as arguments and return values

43. B

42.Message transmission
