Consider the situation of an employee who is using their computer to send and receive email at their place of employment. However, the mail server is situated on a distinct network from the physical connectivity networks, which are all Ethernet networks. Each of the two networks—the employee's network and the mail server's network—is linked by a single router, which also has a connection to the Internet via the workplace's Internet service provider. Include any protocols that are used and any encapsulation/decapsulation that takes place when data moves between the employee's email client, local mail server, and distant mail servers in your explanation of how the email client communicates with the email server.

Consider an employee using their computer to send and retrieve email at their workplace. Only Ethernet networks are used for physical connectivity, but the mail server is located on a separate network. The employee’s network and the mail server’s network are connected by a single router which also has a connection to the Internet via the workplace’s ISP. Explain how the employees email client sends and receives emails using the email server, indicating any protocols involved and where any encapsulation/decapsulation occurs as data travels between the client, local mail server, and remote mail servers.
Transport layer foundational protocols TCP and UDP are TCP and UDP, respectively. Please explain why an application would be designed to utilise TCP as opposed to UDP. Give two (2) distinct examples.
Connectionless protocols have been proposed as an alternative to connection-based protocols; discuss their advantages and disadvantages.
In this comparison, the advantages and disadvantages of connectionless protocols are compared to those of connection-based systems.
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
Destination IP-based forwarding is used by the per-router control plane (sometimes called the classical network) to connect with other routers. If messages are forwarded depending on their destinations' IP addresses, what are the boundaries of this approach? Include a description of at least three limitations, preferably with examples. To what extent does Software-Defined Networking (SDN) contribute to solving these problems? The examples will serve as the explanation.
The Transmission Control Protocol/Internet Protocol (TCP/IP) suite is based onDepartment of Defense’s theoretical model. It has become the standard forcommunications protocol is computer networks. With the aid of diagrams,discuss in details the importance of TCP/IP in computer communications
The use of layered protocols is supported by two main arguments. You must provide evidence for your claims.
compare connectionless (UDP) and connection-oriented(TCP) communication for distributed computing. Use human interactions to differentiate between the two types of communications. In your response, include real world scenario where one is advantageous over the other
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.
Compared to connection-based protocols, consider the benefits and drawbacks of connectionless protocols.
INTERCONNECTED COMPUTER NETWORKS Data collision is caused when many senders access the media at the same time; in order to avoid this, what protocol(s) are available, and at what layer(s) do they operate? Are these protocols able to provide a transport that is free of collisions? In the event that this is not the case, what other potential solutions are available for fixing the issue?
