True or False

Statement The DNS namespace is hierarchical. Protocols at the transport layer make use of the service offered by the network layer UDP provides reliable data transfer Both TCP and UDP use a checksum to detect errors. Clark's algorithm can sometimes help reduce bandwidth usage when TCP is used. With Selective Repeat, the sender and receiver always agree on what packets have been received/not received at all times.
