Computer Network Basics Questions Long
A physical network topology refers to the actual physical layout or arrangement of devices, cables, and other components in a network. It describes how the devices are physically connected to each other and how they are physically arranged in a network. Physical topologies include bus, star, ring, mesh, and hybrid topologies.
On the other hand, a logical network topology refers to the way data flows in a network, regardless of the physical layout. It defines how devices communicate with each other and how data is transmitted between them. Logical topologies include bus, ring, star, mesh, tree, and hybrid topologies.
The main difference between physical and logical network topologies is that physical topology deals with the physical connections and layout of devices, while logical topology focuses on the logical paths and flow of data within a network.
Physical topology determines the physical distance between devices, the type of cables used, and the overall physical structure of the network. It is concerned with the physical placement of devices such as computers, switches, routers, and servers, as well as the physical connections between them. Physical topology is essential for understanding the physical limitations and constraints of a network, such as cable length limitations or the need for additional hardware.
Logical topology, on the other hand, is concerned with how data is transmitted between devices in a network. It defines the logical paths that data takes from the source device to the destination device. Logical topology is independent of the physical layout and can be changed without affecting the physical connections. It determines how devices communicate with each other, how data is routed, and how network protocols are implemented.
In summary, physical topology deals with the physical layout and connections of devices in a network, while logical topology focuses on the logical paths and flow of data within the network. Both physical and logical topologies are important for understanding and designing computer networks.
