Data transmission : Physical versus logical topology

The video tutorial explains the difference between physical and logical network topologies. Physical topology refers to the actual arrangement of network components like cables and devices, while logical topology describes the data flow paths. An example is given using a switch and VLANs, showing how logical topology can change without altering the physical setup.

What does physical topology refer to in a network?

• The data transfer paths in a network

• The virtual networks created on a switch

• The actual physical layout of network components

• The appearance of network devices to users

How are network devices interconnected in a physical topology?

• Using wireless signals

• Through cables and wires

• Via satellite connections

• Using cloud services

What does logical topology describe?

• The speed of data transfer

• The number of devices in a network

• The path over which data is transferred

• The physical arrangement of network cables

What is the role of VLANs in a network?

• To enhance the speed of data transfer

• To reduce the number of network devices

• To create multiple virtual networks on a single switch

• To increase the physical size of a network

How does logical topology differ from physical topology?

• Logical topology describes the physical layout of devices

• Logical topology can change the flow of data from a user's perspective

• Logical topology is always the same as physical topology

• Logical topology is only concerned with wireless networks
