Flow Control in Networking Quiz

What is the primary focus of flow control in networking?

• Sender's speed

• Network bandwidth

• Receiver's speed

• Data frame size

Which layer of the OSI model does the data link layer correspond to?

• First layer

• Second layer

• Fourth layer

• Third layer

What happens if a fast sender transmits data to a slow receiver?

• Receiver processes all data

• Data frames are lost

• Sender slows down automatically

• Data is transmitted successfully

What is flow control primarily concerned with?

• Error detection

• Speed matching

• Data encryption

• Network routing

Which of the following is NOT a service offered by the data link layer?

• Framing

• Flow control

• Data encryption

• Error control

What must the receiver do before its memory is full?

• Stop sending data

• Inform the sender

• Increase memory capacity

• Change the flow control protocol

Which protocol is associated with noiseless channels?

• Stop-and-wait protocol

• Stop-and-wait ARQ

• Go-back-N ARQ

• Selective-repeat ARQ

What does ARQ stand for in flow control protocols?

• Automatic Repeat Request

• Automatic Repeat Query

• Automatic Response Request

• Automatic Response Query

What is the role of the sender in flow control?

• To acknowledge received data

• To process incoming data

• To increase transmission speed

• To send data at an agreed speed

What is the consequence of a slow sender and a fast receiver?

• Sender must speed up

• Receiver's memory fills up

• Data loss occurs

• No issues arise
