Flow Control and Stop-and-Wait Protocol Quiz

What is the primary focus of flow control in networking?

• Receiver's speed

• Data integrity

• Sender's speed

• Network bandwidth

Which layer of the OSI model does flow control primarily operate in?

• Transport layer

• Application layer

• Data link layer

• Network layer

What does the stop-and-wait protocol require after sending a frame?

• Send multiple frames

• Wait for an acknowledgment

• Change the transmission speed

• Terminate the connection

What happens if the sender sends data too quickly for the receiver to handle?

• Data is lost

• Data is stored indefinitely

• Receiver processes all data

• Connection is automatically terminated

Which of the following is NOT a problem associated with the stop-and-wait protocol?

• Lost data

• Excessive bandwidth usage

• Delayed acknowledgment

• Lost acknowledgment

In the context of flow control, what does 'unidirectional data transmission' mean?

• Data is transmitted in both directions at once

• Data can only be sent or received at one time

• Data can be sent and received simultaneously

• Data transmission is bidirectional but slow

What is the main advantage of the stop-and-wait protocol?

• Simultaneous transmission

• Error correction

• Simplicity

• High data throughput

What does the term 'flow control' refer to?

• Ensuring data security

• Increasing data transmission rates

• Coordinating data transmission speed

• Managing network congestion

What is a potential consequence of lost data in the stop-and-wait protocol?

• Automatic error correction

• Immediate retransmission

• Data is stored for later processing

• Infinite waiting time for acknowledgment

Which of the following protocols is used for noiseless channels?

• Stop-and-wait protocol

• Select-repeat ARQ

• Go-back-N ARQ

• Stop-and-wait ARQ
