1. Logical topology

   Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks. Network topology is the topological structure of a network and may be depicted physically or logically. It is an application of graph theory wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various components of a network (e.g., device location and cable installation), while logical topology illustrates how data flows within a network. Distances between nodes, physical interconnections, transmission rates, or signal types may differ between two different networks, yet their logical topologies may be identical. A network’s physical topology is a particular concern of the physical layer of the OSI model. Examples of network topologies are found in local area networks (LAN), a common computer network installation. Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric shape that can be used to describe the physical topology of the network. A wide variety of physical topologies have been used in LANs, including ring, bus, mesh and star. Conversely, mapping the data flow between the components determines the logical topology of the network. In comparison, Controller Area Networks, common in vehicles, are primarily distributed control system networks of one or more controllers interconnected with sensors and actuators over, invariably, a physical bus topology.

1. logical topology

   Logical topology refers to the virtual arrangement or mapping of nodes in a network representing the path of data transmission, disregarding the physical layout of the network elements such as devices, cables, and ports. This arrangement outlines how data travels in the network from one device to another, including its protocols, procedures, or rules used for communication. It can be reconfigured or modified with changes in the network control programs without any alteration to the physical topology. Logical topologies include ring, bus, star, and hybrid structures.

1. Logical topology

   Logical topology is the arrangement of devices on a computer network and how they communicate with one another. How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology. Physical topology defines how the systems are physically connected. It represents the physical layout of the devices on the network. Where, the Logical topology defines how the systems communicate across the physical topologies. Logical topologies are bound to network protocols and describe how data is moved across the network. There are attempts to study the logical topology of the Internet by network scientists such as Albert-László Barabási. EXAMPLE : twisted pair Ethernet is a logical bus topology in a physical star topology layout. while IBM's token ring is a logical ring topology, it is physically set up in star topology. There are two main types of logical topologies: • shared media topology • token-based topology Shared Media In a shared media topology, all the systems have the ability to access the physical layout whenever they need it. The main advantage in a shared media topology is that the systems have unrestricted access to the physical media. Of course, the main disadvantage to this topology is collisions. If two systems send information out on the wire at the same time, the packets collide and kill both packets. Ethernet is an example of a shared media topology. To help avoid the collision problem, Ethernet uses a protocol called Carrier Sense Multiple Access/Collision Detection. In this protocol, each system monitors the wire, listening for traffic. If traffic is detected, the system waits until it hears no traffic before it sends packets out. If a situation occurs where two systems send out packets at the same time and a collision occurs, each system waits for a period of time before it retries. This time period is different for each system, so that the collision does not occur again. For small networks, the shared media topology works fine; however, as you begin to add more systems to the network, there is a greater opportunity for collisions. To help reduce the number of collisions, many networks are broken up into several smaller networks with the use of switches or hubs, and each network is then referred to as its own collision domain. Shared media networks are typically deployed in a bus, star, or hybrid physical topology. Logical topology and physical topology are parts of network topology.
