List computer networking media : What is half duplex and full duplex?

The video tutorial explains the differences between hubs and switches, focusing on bandwidth allocation and duplex settings. It highlights the advantages of using switches over hubs, such as dedicated bandwidth and the ability to operate in full duplex mode, which allows simultaneous sending and receiving of data. The tutorial also covers the importance of correct duplex negotiation to avoid network issues and discusses the scalability and efficiency of switches in modern networks. Finally, it introduces Layer 2 switches and their role in the OSI model.

What is the main advantage of using a switch over a hub in terms of bandwidth?

• Switches require more power than hubs.

• Switches allocate dedicated bandwidth to each port.

• Switches operate at a slower speed than hubs.

• Switches provide shared bandwidth to all devices.

How does full duplex communication differ from half duplex?

• Full duplex is slower than half duplex.

• Full duplex requires a third-party device to manage traffic.

• Full duplex only allows data to be sent, not received.

• Full duplex allows simultaneous sending and receiving of data.

What analogy is used to describe half duplex communication?

• A landline telephone

• A walkie talkie

• A mobile phone

• A satellite radio

What happens if one side of a connection is set to full duplex and the other to half duplex?

• The connection will operate at full speed.

• The connection will be more secure.

• The connection will experience problems.

• The connection will automatically adjust to half duplex.

Why is collision detection turned off when full duplex is enabled?

• Because devices cannot send and receive simultaneously.

• Because it is not compatible with switches.

• Because collisions are impossible in full duplex mode.

• Because it increases the speed of the network.

What is a key advantage of switches over hubs and bridges?

• Switches have fewer ports.

• Switches can process frames at wire speed.

• Switches are cheaper to manufacture.

• Switches require less maintenance.

At which OSI layer do traditional switches operate?

• Layer 2

• Layer 3

• Layer 4

• Layer 1
