Internet Structure: Circuit vs. Packet Switching

This video concludes a series on internet structure by discussing circuit and packet switching. Circuit switching creates a dedicated path for data, ensuring quality but potentially wasting bandwidth. It's ideal for constant link needs like real-time video. Packet switching, more common, sends data in independent packets, maximizing bandwidth use but not guaranteeing quality. It's more efficient and adaptable, especially if network nodes fail. The video summarizes these methods, highlighting their differences and applications.

What is the main focus of this video series?

• Internet history

• Internet protocols

• Internet structure

• Internet security

What is a key feature of circuit switching?

• Bandwidth is reserved in advance

• Packets are sent independently

• Data is sent in real-time

• It is more affordable

Why is circuit switching ideal for real-time video?

• It is less complex

• It is more efficient

• It guarantees transmission quality

• It uses less bandwidth

What is a disadvantage of circuit switching?

• It is more expensive

• It requires complex infrastructure

• It causes bandwidth wastage

• It is less reliable

How does packet switching handle data?

• Data is sent with reserved bandwidth

• Data is sent in a single block

• Data is sent in a fixed path

• Data is sent in smaller, independent blocks

What is a benefit of packet switching over circuit switching?

• It guarantees quality

• It uses all available bandwidth

• It requires more infrastructure

• It is less efficient

What happens to packets in packet switching?

• They follow a single path

• They are sent via the least congested route

• They are sent with reserved bandwidth

• They are sent in order

Which switching method supports store and forward transmission?

• Circuit switching

• Packet switching

• Both methods

• Neither method

What is a key difference between circuit and packet switching?

• Circuit switching is more efficient

• Packet switching is less reliable

• Packet switching reserves bandwidth

• Circuit switching uses a dedicated path
