Networking Concepts Quiz

What is the primary function of forwarding in a network?

• To break messages into packets

• To move packets from input to output links

• To allocate resources for calls

• To determine source-destination paths

Which of the following best describes routing?

• Process of breaking messages into packets

• Global action of determining paths

• Local action of moving packets

• Action of queuing packets

What happens when the arrival rate to a link exceeds its transmission rate?

• Packets are transmitted immediately

• Packets are stored indefinitely

• Packets are queued or dropped

• Packets are forwarded without delay

In the context of packet-switching, what does 'store and forward' mean?

• Packets are transmitted in real-time

• Packets are forwarded without waiting

• Entire packets must arrive before transmission

• Packets are stored for future use

What is the purpose of Frequency Division Multiplexing (FDM)?

• To ensure dedicated resources for each call

• To divide frequencies into bands for calls

• To allocate time slots for calls

• To increase packet transmission speed

How does Time Division Multiplexing (TDM) allocate resources?

• By dividing time into slots

• By reserving frequency bands

• By ensuring dedicated circuits

• By allowing unlimited resource sharing

What is the role of protocols in packet-switching?

• To ensure reliable data transfer and congestion control

• To increase transmission rates

• To eliminate packet loss

• To allocate dedicated resources

What does the traceroute program measure?

• Transmission speed

• Queue length

• Delay from source to router

• Packet loss

What is the significance of a full queue in a router?

• It ensures faster transmission

• It leads to packet loss

• It indicates efficient processing

• It allows for more packets to be queued

What is the primary characteristic of circuit-switching?

• Resource sharing

• Packet queuing

• Dynamic allocation

• Dedicated resources
