What is a key characteristic of UDP compared to TCP?

• Connection-oriented communication

• No handshaking before data transfer

• Guaranteed delivery of data

• Built-in error correction

How does a UDP sender identify the recipient of the data?

• By initiating a connection handshake

• By broadcasting the data to all possible recipients

• By embedding the recipient’s IP address and port number in each packet

• By using a predefined routing table

What does the UDP receiver extract from a received packet?

• Only the data payload

• Acknowledgment number for the packet

• Sender's IP address and port number

• Error correction information

Which of the following is true about data transmitted via UDP?

• It is always delivered in order.

• It includes built-in error correction.

• It requires a handshake before transmission.

• It may be lost or received out of order.

From the application’s viewpoint, UDP provides:

• Reliable, ordered transfer of data.

• Unreliable transfer of datagrams between client and server.

• Guaranteed data integrity during transmission.

• Streaming of continuous byte sequences.

Which of the following best describes UDP’s design?

• Fast but unreliable

• Reliable but slow

• Secure and connection-oriented

• Efficient and guaranteed delivery

Why might UDP be chosen over TCP for certain applications?

• It has lower latency due to no connection setup.

• It guarantees delivery even on congested networks.

• It is more secure.

• It automatically retransmits lost packets.

What must the server process do before a TCP client can contact it?

• Send a handshake request to the client

• Establish a connection with the client

• Create a socket to welcome client connections

• Bind to a client-specific port number

How does the TCP client initiate communication with the server?

• By specifying the server’s IP address and port number when creating a socket

• By creating a datagram and sending it to the server

• By broadcasting a connection request

• By waiting for the server to send a connection signal

What happens when a client establishes a connection with a TCP server?

• The server uses the same socket to communicate with all clients.

• The client creates a duplicate of the server socket.

• The server assigns a unique IP address to the client.

• The server creates a new socket to communicate with the specific client.
