This refers to the physical structure of a network, like how the wires are connected to different computers in a network.
 A Ring Topology B Logical Topology C Physical Topology D Bus Topology
Explanation:

Detailed explanation-1: -A network topology is the physical and logical arrangement of nodes and connections in a network. Nodes usually include devices such as switches, routers and software with switch and router features. Network topologies are often represented as a graph.

Detailed explanation-2: -Physical Topology – the way a network is laid out physically. Two or more devices connect to a link Two or more links form a topology. A linking device in a network is called a node. There are four basic types of topologies available.

Detailed explanation-3: -Physical topology refers to the interconnected structure of a local area network (LAN). The method employed to connect the physical devices on the network with the cables, and the type of cabling used, all constitute the physical topology.

Detailed explanation-4: -There are three basic physical topologies: bus, ring, and star. That is, the cables in a network approximate the shape of a bus, ring, or star. In a bus physical topology, all devices are connected in a line along a single channel.

Detailed explanation-5: -Physical – The physical network topology refers to the actual connections (wires, cables, etc.) of how the network is arranged.
