What is the purpose of the "Acknowledgment Number" field in the TCP header?

• A. It identifies the application that sends the segment.
  

• B. It indicates the length of the TCP header.
  

• It indicates the sequence number of the next segment's first byte that the receiver is expecting to receive.
  

• D. It is used for TCP flow control.

What is the purpose of the "Window" field in the TCP header?

• A. It identifies the application that receives the segment.
  

• B. It indicates the length of the TCP header.
  

• C. It specifies the maximum number of bytes that are allowed by the sender.
  

• D. It is used for TCP flow control.

What is the purpose of the "Checksum" field in the TCP header?

• A. It identifies the application that sends the segment.

• B. It indicates the length of the TCP header.

• C. It is used for error detection in the TCP segment.

• D. It specifies the maximum number of bytes allowed by the receiver.

Which of the following statements accurately describes how port numbers are typically allocated?

• The source port number is specified by the application of a server, while the destination port is randomly allocated by the client.

• The source port number is randomly allocated by the client, while the destination port is specified by the application of a server.

• Both the source and destination port numbers are randomly allocated by the client.

• Both the source and destination port numbers are specified by the application of a server.
