2.● A glue that holds the whole Internet together is the network layer protocol,(71). Unlike most older network layer protocols, it was designed from the beginning with internetworking in mind. Its job is to provide a -(72) way to transport datagrams from source to destination, without regard to whether these machines are on the same network or whether there are other networks in between them.Communication in the Internet works as follows. The (73)layer takes data streams and breaks them up into datagrams. Each datagram is transmitted through the Internet, possibly being fragmented into smaller units as it goes. When all the pieces finally get to the destination machine, they are reassembled by the(74) layer into the original datagram. This datagram is then handed to the transport layer, which inserts it into the receiving process' input stream.An IP datagram consists of a header part and a text part. The header has a (75) part and a variable length optional part.(71) A. IP (Internet Protocol)B. IP (Interworking Protocol)C. TCP (Transport Control Protocol)D.

    ● A transport layer protocol usually has several responsibilities. One is to create a process-to-process communication; UDP uses （71） numbers to accomplish this. Another responsibility is to provide control mechanisms at the transport level. UDP does this task at a very minimal level. There is no flow control mechanism and there is no （72） for received packet. UDP,however, does provide error control to some extent. If UDP detects an error in the received packet, it will silently drop it．

    The transport layer also provides a connection mechanism for the processes. The （73） must be able to send streams of data to the transport layer. It is the responsibility of the transport layer at （74） station to make the connection with the receiver, chop the stream into transportable units,number them, and send them one by one. It is the responsibility of the transport layer at the receiving end to wait until all the different units belonging to the same process have arrived, check and pass those that are （75） free, and deliver them to the receiving process as a stream.
