What is the difference between a network's physical topology and its logical topology?
What will be an ideal response?
The physical topology of a network refers to the way that all devices are physically connected. It takes into account the way that the computers are cabled together and whether they have a central connecting device or not. The logical topology of a network refers to the way that the signals travel from one network device to another. Although all the devices may appear to pass data in certain direction, the actual path the data takes may be different-often it depends on the interconnecting device such as a hub or switch.
