What happens when a TCP sender detects packet loss?

a: It reduces the congestion window size. Explanation

Explanation

b: It stops transmitting all packets. Explanation

Explanation

c: It increases the transmission rate. Explanation

Explanation

d: It ignores the loss and continues sending. Explanation

Explanation

Why is TCP considered a connection-oriented protocol?

a: It does not require an initial handshake. Explanation

Explanation

b: It ensures data is delivered in sequence and without errors. Explanation

Explanation

c: It does not retransmit lost packets. Explanation

Explanation

d: It only supports one-way communication. Explanation

Explanation

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

a: To verify the receiver's IP address. Explanation

Explanation

b: To establish a reliable connection before data transfer. Explanation

Explanation

c: To encrypt the data being transmitted. Explanation

Explanation

d: To check network congestion levels. Explanation

Explanation

Which TCP mechanism controls the flow of data to prevent overwhelming the receiver?

a: Slow Start Explanation

Explanation

b: Congestion Window Explanation

Explanation

c: Sliding Window Explanation

Explanation

d: Checksum Explanation

Explanation

What is the main difference between Go-Back-N and Selective Repeat protocols?

a: Go-Back-N retransmits all packets after a loss, while Selective Repeat only retransmits lost packets. Explanation

Explanation

b: Go-Back-N does not use acknowledgments, while Selective Repeat does. Explanation

Explanation

c: Go-Back-N allows unlimited packet transmission, while Selective Repeat does not. Explanation

Explanation

d: Go-Back-N requires TCP, while Selective Repeat does not. Explanation
