A webpage is a single HTML file that is of size 300,000 bytes. Client has already received from Host all bytes up to including byte 20,000. Suppose Host then sends two segments to Client back-to-back. The first and the second segment contain 2000 and 1000 bytes of data respectively. Client sends an acknowledgment whenever it receives a segment from Host. In the first ack segment, the source port number is 5100.(a) In the first segment sent from Host to Client, what are the sequence number, and destination port number?(b) If the first segment arrives before the second segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number, the source port number, and the destination port number?(c) If the second segment arrives before the first segment, in the acknowledgment of the first arriving segment, what is the acknowledgment number?(d) Assume the source port number used by the above browser is 5100. Now a second browser is opened on the client also wants to request the same webpage. Does the second browser use the same source port number of 5100? Why? What is the destination port number?
