INTERNET TECHNOLOGIES2Answer 1: When an Email is send by the source using the TCP, the data arrive at the transportlayer where the data encapsulation protocol begins. The end result will depend on theinformation handle by the TCP or PDU. TCP is a connection-oriented protocol where thedata is a successful deliver at the receiving host. The data that has been received from theapplication layer, TCP divides that data into multiple segments and to each segments a headeris attached. The header of the segment contain the ports of the sender and the recipient,ordering information of the segment and field of data, which is also known as checksum. Onboth the hosts of the TCP protocols the checksum data is used and determine that the datatransferred is with error or without error. In order to establish a connection through TCP, thesegments are used by TCP that determine whether the host who will be receiving is ready forthe data to receive. The sending TCP establishes a connections on the host who will bereceiving, that sends a SYN segment to the running peer TCP protocol. The TCP that isreceiving returns an ACK segment and acknowledge the segment receipt successfully. Thereis another ACK segment that the sending TCP sends. Such control information that exchangeis referred as three-way handshake.The PDU protocol is connectionless. The message received from the application layeris taken by the PDU protocol. It then format into UDP packets. In each of the packet of thePDU a header is attached in which there is a host port for sending and receiving, a checksumand a field with packet length. The packet then send by the sending PDU process to the peerPDU process where the host can receive it. Through application layer it can be determine thatpacket was receive by the receiving PDU process. There is no notification requires for thereceipt by the PDU. Moreover, the three-way handshake is not used by the PDU.

INTERNET TECHNOLOGIES3Answer 2:The formula known to us is bit rate = Bandwidth*log (1+SNR)It is given that, Bandwidth = 7 x 10^6SNR = 64Hence bit rate = 7 x 10^6 log (65) = 7 x 6. 022 x 10^ 6 = 42.154 MbpsThe Shannon formula gives us 42.154 Mbps, the upper limit. For better performance wechoose something lower, 32 Mbps, for example. Then we use the Nyquist formula to find thenumber of signal levels.32 Mbps = 2x 1 MHz x log LL = 65536Hence the signal level is 65536Answer 3:The comparison of baseband and broadband transmission are as follows. The baseband transmission uses digital signalling rather than single wire and it iseither in form of light or electrical pulse. The overall bandwidth is occupied by digital signalthat is used in baseband transmission. This is used to transmit an individual data signal. Thecommunication emerging through baseband is bidirectional that allows computer devices touse single cable for sending and receiving data. However, in baseband communication, thedata that is sent and received cannot happen at the same time and at the same wire. Themultiplexing is the process used by baseband transmissions to transmit multiple digitalsignals on a single wire. The baseband communication uses time division multiplexing where
