Explanation / Answer

1)A protocal suite is a protocal used for networking and

communication.These are generally called as TCP/IP protocal.

2)The Transport layer protocals are used to deliver data across the network.These include TCP (Transmission Control Protocol),UDP(User Datagram Protocol)

3)The application layer provides services for user applications to employ(eg:browser).The application layer protocals include SMTP,FTP.

4)Hardware is not a protocal its a tangable semiconductor used for successful functioning of a computer.

5)Message cost is not a protocal.because we dont bother about the cost of the message at protocal layer level.

6)Transport layaer is responsible for calculating best path for transfer of packets.

7)session layer is responsible for dialogue control. Therefore the answer is non of the above.

8)The Network layer is responsible for accepting IP datagrams and supporting inter device connections and can also multiplex several transport connections on to one network.(NAC)

9)802.3 is a working group which defined Ethernet.

10)Transport layer is reponsible for segmenting, transfering, and reassembling data.

11)Network Access is reponsible for controlling the hardware devices and Media that makes up the network

12)Data Link layer is responsible for exchanging frames between devices.

13)Decapsulation is done from top layer to botton layer.

14)Sent to Layer 3 to become a Packet at network layer from data link layer as a frame.

15)Sent from Layer 7 to below layer stripping all the headers to make the data usable by the lower layers.

16)framing is the process of cutting a messages into smaller pieces to accommodate transmission.

17)Suite is used for visualizing the protocals.

18)IP takes segments and creates packets through a process referred to as encapsulation.
