FUNDAMENTALS OF COMPUTER

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 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-3: -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. Signals propagate along the entire length of the bus.

Detailed explanation-4: -1. Physical Topology : Physical topology indicates arrangement of different elements of a network. It reflects physical layout of devices and cables to a form a connected network. It is concerned with essentials of network ignoring minute details like transfer of data and device type.

Detailed explanation-5: -A physical topology explains how computers, devices or nodes connect with each other in a network based on their location. It involves assessing the physical layout of network cables and workstations. Conversely, a logical topology explains how data flows from one device to another based on network protocols.
