Physical topology and logical topology are two key concepts in computer networking that describe different aspects of how devices are connected within a network.

1.Physical Topology:
Physical topology refers to the physical layout or arrangement of devices and cables in a network. It describes the actual physical connections between devices, such as the layout of cables, the placement of routers, switches, and other networking equipment, and the physical locations of devices within a network. Physical topology determines how devices are physically interconnected and how data flows between them through the physical medium, such as copper cables, fiber-optic cables, or wireless signals.
Physical topology is concerned with the physical infrastructure of the network and how devices are physically connected, regardless of how data is logically transmitted between them.
2. Logical Topology:
Logical topology, on the other hand, refers to the way data is transmitted between devices in a network, irrespective of the physical layout. It describes the logical paths or routes that data takes as it travels from the source to the destination. Logical topology defines how devices communicate with each other through the use of network protocols, addressing schemes, and routing algorithms.d
While physical topology focuses on the physical layout of devices and cables, logical topology deals with the logical paths and protocols used for data transmission within a network. Both physical and logical topologies are essential for understanding how networks are structured and how data flows within them.
