which three TCP services that are not supported by UPD?
| Transmission Control Protocol | User DataGram Protocol |
| TCP provides reliable delivery and inorder delivery as a service | UDP does not give us reliable and inorder delivery |
| TCP provides Data flow control | UDP does not provide data flow control |
| TCP provides HTTP,SMTP, and FTP as a service to us |
UDP does not give us these services. |

TCP Connection Management: Draw a Trace of the TCP connection set up known as the three-way handshake. Assume the connection is initiated by a Web Client to a Web server. The trace must clearly indicate special flags used in the TCP header of each step and show the relation between sequence numbers of the exchanged segments. In addition also indicate if each segment may or may not contain application data (according to the TCP implementation described in the textbook). Also...
Which of the following is NOT normally used in system hardening: a. Changing TCP/IP parameters b. Removing unnecessary services c. Removing unnecessary NICs d. Renaming administrator userids
Which of the following is NOT normally used in system hardening: a. Changing TCP/IP parameters b. Removing unnecessary services c. Removing unnecessary NICs d. Renaming administrator userids
TCP Connection Setup consists of a "three-way handshake:" SYN,
SYN-ACK, ACK.
Which one(s) of these three
segments specifies an initial sequence number?
Which one(s) of these three
segments is permitted to contain application data?

TCP/IP protocol suite. How can the multiplexed TCP and UDP packets be (4 marks) (c) Describe briefly the impact of congestion on packet delay and throughput. Describe (6 marks) (d) Fig. Q1 shows a network adopting the virtual-circuit approach to transmit demultiplexed at the destination? the strategy used in the Internet to...
Which of the following in connectionless – Ethernet, IP, TCP? Explain why. Which of the following is unreliable – Ethernet, IP, TCP, UDP? Explain why. Why is it a good idea to have reliability at the transport layer? How many layers of the hybrid TCP-IP stack does a typical Router implement? Switch implement? Destination host implement?
Identify and describe how the TCP three-way handshake works to ensure data delivery.
7. Question A Transmission Control Protocol (TCP) connection is in working order and both sides can send each other data. What is the TCP socket state? SYN_SENT ESTABLISHED SYN_RECEIVED LISTEN8. Question Which field in a Transmission Control Protocol (TCP) header provides the next expected segment? Sequence number Data offset Checksum Acknowledgement number9. Question Which field in a Transmission Control Protocol (TCP) header is not typically used in modern networking? Acknowledgement number Urgent pointer Sequence number Checksum11. Question In what order will the Transmission Control Protocol (TCP) generally send all segments? Largest to smallest Prioritized Random Sequential12. Question...
TCP headers and segmentation (B) 10. Which of the following flelds in the UDP header Is NOT found in the TCP header? source port destination port checksum length 11. The value of the acknowledgement field in a TCP segment defines Number of bytes to retransmit Number of bytes to receive Starting point of next bytes to receive in sequence Total number of bytes left 12. Suppose Host A sends one segment with sequence number 38 and 4 bytes of data...
