What is physical topology and logical topology?
Physical topology refers to the physical layout of a network, including the physical connections between devices and the physical media used to connect them. Examples of physical topologies include bus, ring, star, and mesh.
Logical topology refers to the logical arrangement of a network, including the paths that data takes through the network and the protocols that are used to manage the network. Examples of logical topologies include client/server, peer-to-peer, and cloud networking.
Physical topology
Physical topology determines the physical layout of a network, including the physical connections between devices and the physical media used to connect them. The following are some of the most common physical topologies:
- Bus topology: Devices are connected to a single backbone cable.
- Ring topology: Devices are connected to a single circular cable, with each device connected to the two adjacent devices.
- Star topology: Devices are connected to a central hub or switch.
- Mesh topology: Devices are connected to each other in a mesh of connections.
Logical topology
Logical topology determines the logical arrangement of a network, including the paths that data takes through the network and the protocols that are used to manage the network. The following are some of the most common logical topologies:
- Client/server topology: A central server provides services to multiple clients.
- Peer-to-peer topology: All devices are equal, and there is no central server.
- Cloud networking: A network that is hosted in the cloud, and is accessed by devices over the internet.
