Write a Java TCP MultipleClient-Server Program for following scenario. NOTE Server Details are in the above figure Client-Server communicates continuously until the Client send Bye to the Server Use Multithreading for Multiple Clients NOTE : 1 cm = 0.39 inches 1 cm = 0.03 foot 1 cm = 0.01 meter Sample Ouput: Client Server 1 – cm to inches 2 – cm to foot 3 – cm to meter Enter length in cms (int) : 10 Received from Server 3.9 inches 1 – cm to inches 2 – cm to foot 3 – cm to meter Enter length in cms (int) : BYE Received from Server BYE Client DISCONNECTED Server Waiting for the Cline to be Connected… CONECTION ESTABLISHED Received From Client 10 cms Sent to Client 3.9 inches Received From Client BYE Sent to Client BYE HINT : When client choses 1 for cm to inches and enter 10, then the client sends the string 110 to the Server. Where the first char ‘1’ represents the cm to inches and the other 2 chars represents the 10.
Both TCP and UDP are separate protocols that may be contrasted with one another. Give us an example of two circumstances in which you, as a software architect, might choose to make use of TCP rather than UDP.

Please solve it correctly and please provide explanation of your answers. A PC and a Web Server are communicating over a TCP connection. The PC had started the three way handshake with the initial sequence number of 3069 . The Web Server's initial sequence number is 4830 . The window size of the PC is 815 bytes and the window size of the Web Server is 463 bytes. Using the third TCP handshake ack segment the PC sends the http request of the size 396 bytes to the Web Server. Then the Web Server answers with 3 segments containing the requested data. The first segment size is 42 bytes and the second segment size is 276 bytes and the third segment size is 146 bytes respectively. The PC receives all three segments within the timer. But unfortunately the second segment was corrupted. So the PC immediately sends an acknowledgement segment. Assume that the PC uses Selective Repeat/Reject ARQ. (d) What will be the window size of PC A after receiving only the first segment from webserver? (e)…

Both UDP and TCP use port numbers to identify the destination entity when delivering a message. Give two reasons for why these protocols invented a new abstract ID (port numbers), instead of using process IDs, which already existed when these protocols were designed.
While developing a reliable transport protocol, early versions of the protocol discussed in class used a NAK message, sent by the receiver to the sender to indicate a packet was not correctly received. This kind of message, however, is not found in further protocols, like GBN, SR or even TCP. Why not? In other words, why don't these protocols provide a way to signal to the sender that the received message was received with an error
For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.
We previously said that a programme should utilise UDP as its transport layer protocol because UDP allows for more control over when data is provided to a section and when it is not (the TCP).A. Why does the programme have greater control over which data is sent into a segment than the user?
