DataLinkLayer - Network

What does the term "Packetizing" refer to in network communication?

• Combining multiple data streams into one

• Breaking data into small pieces for transmission

• Compressing data to reduce its size

• Encrypting data for security

Which protocol allows communication in only one direction?

• Full-Duplex Protocol
  

• Half-Duplex Protocol
  

• Simplex Protocol
  

• Bidirectional Protocol

In the Stop-and-Wait protocol, what does the sender do after sending a data frame?

• Sends another frame immediately

• Waits for an acknowledgment (ACK)

• Checks the data for errors

• Closes the connection

What kind of communication occurs in a Simplex Protocol?

• Bidirectional

• Half-duplex

• Unidirectional

• Full-duplex

What happens in an Unrestricted Simplex Protocol?

• The sender waits for permission to transmit

• Data frames are continuously sent without restrictions

• The sender waits for acknowledgments before sending data

• The receiver sends feedback to the sender

What is the role of the ACK signal in data transmission?

• To send data to the receiver

• To request data from the sender

• To acknowledge successful receipt of data

• To terminate the connection

Which protocol uses the sliding window technique for data transmission?

• UDP

• ICMP

• TCP

• TCP and UDP

What is the purpose of the One-Bit Sliding Window Protocol?

• To send multiple frames at once without any acknowledgment

• To ensure reliable and sequential delivery of data frames

• To transmit data without any errors

• To allow communication in only one direction

In the One-Bit Sliding Window Protocol, what happens after a frame is sent?

• The sender sends another frame immediately

• The sender waits for an acknowledgment (ACK)

• The receiver sends data back

• The receiver starts a new connection

What happens when a frame is not acknowledged in the Go-Back-N ARQ protocol?

• Only the specific frame is retransmitted

• All frames from the unacknowledged frame onward are retransmitted

• The connection is terminated

• The receiver waits for the next frame
