4- The Transmission Control Protocol (TCP) is known to be one of the most important protocol used in computer networks. It helps to understand and analyse the protocol most effectively and monitor and capture the traffic using a protocol analyser. Using Wireshark capture, analyse the TCP, identify source and destination MAC address, source and destination IP address, and show the full working out of your experiment in a logical structure.

X.25 and Frame Relay are two protocols applied in packet switching data communication. Packet switching is a method of grouping data that is transmitted over a digital network into packets.Based on the description given above, ELABORATE your answer from the questions below:a) Briefly EXPLAIN X.25 and Frame Relay protocols, their protocol layers and equipment used. b) DISCUSS at least FIVE (5) differences between the TWO (2) protocols.
Computer networks Quiz1 9/8/2020 Last Date 12/8/2020 Question 1 Why communication protocols are realized using a layer model? The protocols can be executed faster. Using layers, it is possible to respond faster to changes in requirements (e. g. new hardware, new protocols). The amount of data transferred can be reduced using layered protocols. A complex communication task is solved more easily when split up on multiple layers.
Task NW29. UDP is the simplest transport layer communication protocol. It contains a minimum amount of communication mechanisms. It is considered an unreliable protocol, and it is based on best-effort delivery services. UDP provides no acknowledgment mechanism, which means that the receiver does not send the acknowledgment for the received packet, and the sender also does not wait for the acknowledgment for the packet that it has sent. An end system sends 50 packets per second using the User Datagram Protocol (UDP) over a full duplex 100 Mbps Ethernet LAN connection. Each packet consists 1500B of Ethernet frame payload data. What is the throughput, when measured at the UDP layer? Task DS30
4. The original HTTP protocol used TCP/IP as the underlying protocol. For each page, graphic, or applet, a separate TCP connection was constructed, used, and terminated. This caused several problems: one referred to as the elephant and mice problem and two aspects of connection overhead. Describe both problems. Why were separate connections used? Would UDP rather than TCP be a good alternative? What solution would you propose to these problems to improve HTTP performance?
a) Explain the ARP protocol to a friend. In that explanation,mention what layer it operates at and the kind of service it provides to the layer above it.
State two advantages of dividing a communication system into layers such as e.g. is done in the TCP / IP stack with 5 layers from the application layer down to the physical layer. Also indicate if there is any possible disadvantage to stocking one communication system?
Which two of the following are the most convincing arguments in favour of the use of layered protocols?
1) What is the meaning of protocols in computer networks, name two application layer protocols then explain the purpose for each one.
