10. TCP

Question 1

What ensures reliability in TCP?

Answer 1

Mechanisms like sequence numbers, acknowledgments (ACKs),
retransmissions, and error checking ensure reliable delivery.

Question 2

What is the purpose of the TCP three-way handshake?

Answer 2

To establish a reliable connection by synchronizing sequence numbers and
confirming readiness between the sender and receiver.

Question 3

How does TCP handle flow control?

Answer 3

TCP uses a sliding window protocol to manage the flow of data, ensuring the
sender does not overwhelm the receiver.

Question 4

What is the congestion window, and how does it help manage network
congestion?

Answer 4

The congestion window dynamically adjusts the rate of data transmission
based on network conditions to prevent congestion.

Question 5

What happens during TCP connection termination?

Answer 5

TCP uses a four-step process with FIN and ACK messages to gracefully close
the connection.

Question 6

What is the maximum segment size (MSS) in TCP, and how is it determined?

Answer 6

MSS is the largest amount of data TCP can send in one segment, determined
by subtracting the TCP and IP headers from the MTU.
