Question

explain topology , bus topology, star topology,tree topology,ring topology briefly​

Answer 1

Answer:

Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology – Mesh, Star, Bus, Ring and Hybrid.

In mesh topology each device is connected to every other device on the network through a dedicated point-to-point link.

In star topology each device in the network is connected to a central device called hub. Unlike Mesh topology, star topology doesn’t allow direct communication between devices, a device must have to communicate through hub.

In bus topology there is a main cable and all the devices are connected to this main cable through drop lines. There is a device called tap that connects the drop line to the main cable.

In ring topology each device is connected with the two devices on either side of it. There are two dedicated point to point links a device has with the devices on the either side of it. This structure forms a ring thus it is known as ring topology.

A combination of two or more topology is known as hybrid topology. For example a combination of star and mesh topology is known as hybrid topology.

Answer 2

Answer

Topology- Topology refers to the layout of a computer network. Topology can be described either physically or logically.

1. Physical topology means the placement of the elements of the network,including the location of the devices or the layout of the cables.
2. logically topology maps the flow of data, regardless of the physical layout.
