Routing of data packets
Congestion control
In multiplexing and demultiplexing, which field in the transport layer header helps the receiver identify the correct application process?
Sequence number
Checksum
Port number
IP address
Which of the following is TRUE regarding UDP?
It provides flow control.
It guarantees in-order delivery of packets.
It provides low-latency communication but no reliability.
It ensures retransmission of lost packets.
What is the primary purpose of an acknowledgment (ACK) in reliable data transfer?
To indicate that the receiver has received the data successfully
To request retransmission of a lost packet
To assign a sequence number to the packet
To terminate the connection
Which congestion control mechanism is used in TCP to prevent congestion collapse?
Fast retransmit
Flow control
Slow start, congestion avoidance, and fast recovery
Round-trip time estimation
In TCP, what is the primary purpose of the three-way handshake?
To establish a connection and agree on initial sequence numbers
To close an existing connection gracefully
To send data in an unreliable manner
To avoid congestion in the network
What is the main advantage of using UDP over TCP?

Lower latency and reduced overhead
Built-in congestion control mechanisms
Reliable transmission with retransmissions
Which of the following ensures reliable data transfer in TCP?
