Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Suppose two hosts use a TCP connection to transfer a large file. Which of the following statements is/are False with respect to the TCP connection?1. If the sequence number of a segment is m, then the sequence number of the subsequent segment is always m+1.2. If the estimated round trip time at any given point of time is t sec, the value of the re-transmission timeout is always set to greater than or equal to t sec.3. The size of the advertised window never changes during the course of the TCP connection.4. The number of unacknowledged bytes at the sender is always less than or equal to the advertised window
A
3 only
B
1 and 3 only
C
1 and 4 only
D
2 and 4 only
Explanation: 

Detailed explanation-1: -HTTP and FTP protocols can use multiple TCP connections between the same client and the server.

Detailed explanation-2: -We need to find the sequence number of the segment if all data is sent in only one segment. When all data is sent in one segment, the sequence number of the segment will be the sequence number of the first byte.

Detailed explanation-3: -Answer: If the connection is a TCP (Transmission Control Protocol) connection, the first segment that Computer 1 needs to build is called the “SYN” (Synchronize) segment. The SYN segment is used to initiate a TCP connection and initiate the three-way handshake process between Computer 1 and the other endpoint.
