Networking Concepts Quiz

What is packet switching?

• Packet switching is a method of grouping data into packets before transmitting them over a network.

• Packet switching is a technique used to physically connect devices in a network.

• Packet switching involves converting data into binary code for network transmission.

• Packet switching is a method of grouping data into envelopes before transmitting them over a network.

Explain circuit switching.

• Circuit switching does not require a dedicated communication channel

• Circuit switching involves setting up a dedicated communication channel between two nodes before data transfer can occur.

• Circuit switching is a type of wireless communication

• Circuit switching involves transmitting data in small packets over a shared network

Define message switching.

• Message switching involves direct communication between nodes without storing messages

• Message switching is a technique where messages are encrypted before transmission

• Message switching is a method of communication where messages are stored and forwarded between nodes in a network.

• Message switching is a method of communication where messages are broadcasted to all nodes simultaneously

What is the datagram approach in networking?

• The datagram approach involves sending data in a continuous stream without breaking it into packets

• The datagram approach in networking involves breaking data into small packets that can be sent independently across a network.

• Datagram approach is only used for wired networks, not wireless networks

• In datagram approach, packets are always guaranteed to arrive at the destination in order

How does virtual packet switching approach work?

• Virtual packet switching does not require any addressing information for data transmission.

• Virtual packet switching involves sending data in large chunks without any division.

• Virtual packet switching transmits data only to one destination at a time.

• Virtual packet switching works by breaking data into packets, each with destination information, for independent transmission across a network.

What are the key characteristics of packet switching?

• All packets must follow the same route

• Packet switching is slower than circuit switching

• Data is transmitted in a continuous stream

• Data is broken down into packets for transmission, each packet can take a different route to reach its destination, packets are reassembled at the destination, allows for more efficient use of network resources.

What are the advantages of circuit switching?

• Dedicated communication channels, constant bandwidth, low latency

• Limited scalability, high cost, inefficient resource utilization

• Variable bandwidth, high latency, shared communication channels

• Intermittent connectivity, dynamic routing, high security

How does message switching differ from packet switching?

• Message switching forwards entire messages, while packet switching breaks messages into packets for transmission.

• Message switching and packet switching both break messages into packets for transmission.

• Message switching breaks messages into packets, while packet switching forwards entire messages.

• Packet switching forwards entire messages, while message switching breaks messages into packets.

Discuss the advantages of the datagram approach.

• Advantages of the datagram approach include simplicity, flexibility, efficiency, resilience to network failures, varying speeds and sizes for data transfer, and suitability for real-time applications and scalable networks.

• Complexity, rigidity, inefficiency

• Unsuitable for real-time applications and non-scalable networks

• Susceptibility to network failures, fixed speeds and sizes for data transfer

Compare and contrast virtual packet switching with other switching techniques.

• Virtual packet switching is more efficient and scalable compared to circuit switching and message switching.

• Virtual packet switching is less cost-effective than circuit switching.

• Virtual packet switching is less reliable than circuit switching.

• Virtual packet switching is slower than message switching.
