A logical topology is how devices appear connected to the user. A physical topology is how they are actually interconnected with wires and cables.

What is the difference between physical topology diagrams & logical topology diagrams?
A physical network topology diagram shows the structure of how devices are connected physically inside a network. A logical network topology diagram shows the logical method of communication used by the devices inside the network for network communication.
What is physical network diagram?
A physical network diagram shows the actual physical arrangement of the components that make up the network, including cables and hardware. Typically, the diagram gives a bird’s eye view of the network in its physical space, like a floorplan.
What is a logical network diagram?
A logical network diagram illustrates the flow of information through a network and shows how devices communicate with each other. It typically includes elements like subnets, network objects and devices, routing protocols and domains, voice gateways, traffic flow and network segments.
What is physical and logical network design?
Logical design of a network consists of virtual design while the physical design of a network describes the hardware functions of the network. Logical designs determine the flow of data or communication between two networks while physical design is a communication between two computers connected with cables.
What is a physical network?
The physical network consists of the cables (coaxial cable, twisted pair, fiber optic, and telephone lines) that connect the different hardware residing on the network, the adapter used on computers connected to the network (hosts), and any concentrators, repeaters, routers, or bridges used in the network.
What is physical network topology?
Physical network topology is the placement of the various components of a network and the different connectors usually represent the physical network cables, and the nodes represents usually the physical network devices (like switches).
What are the different types of network diagrams?
There are two main types of network diagrams in project management: the arrow diagramming method (ADM), also known as “activity network diagram” or “activity on arrow”; and the precedence diagramming method (PDM), also known as “node network” or “activity on node.”
What is the use of logical diagram?
Logic diagrams have many uses. In the solid state industry, they are used as the principal diagram for the design of solid state components such as computer chips. They are used by mathematicians to help solve logical problems (called boolean algebra).
What are the 4 types of networks?
- LAN(Local Area Network)
- PAN(Personal Area Network)
- MAN(Metropolitan Area Network)
- WAN(Wide Area Network)
What is logical network topology?
A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Using network equipment such as routers and switches, the logical topology of a network can be dynamically maintained and reconfigured.
What is use of physical and logical topology?
A physical topology describes how network devices are physically connected – in other words, how devices are actually plugged into each other. We’re talking about cables, wireless connectivity, and more. A logical topology describes how network devices appear to be connected to each other.
Is star topology physical or logical?
Star topology has become the dominant physical topology for LANs. The star was first popularized by ARCNET, and later adopted by Ethernet. Each node is connected directly to a central device such as a hub or a switch, as shown in Figure 5.17.
What is an example of logical topology?
Logical topology means how the network device layout will be shown and how the data will be transferred. For example − Ring, Bus, Star, and Mesh. For example − Ring and Bus. In this topology, we are concerned with how data will be transferred from the actual path.
What are the two main types of network topology diagrams?
There are two approaches to network topology: physical and logical. Physical network topology, as the name suggests, refers to the physical connections and interconnections between nodes and the network—the wires, cables, and so forth.
What is a layer 3 network diagram?
Layer 3 diagrams are about subnets, routing and the IP spaces. These are used when explaining a network to. designers of the network as part of the analysis and design phase, before deciding on specific equipment. application developers, who should be spared the details of how the network is cabled.
What should be included in a physical network diagram?
Physical Network Diagram A physical network topology diagram will include icons of elements like workstations, servers, routers, and switches, while the lines between these elements represent cable connections.
What is a logic diagram called?
Deductive diagrams similar to the conventional ‘fault tree’ diagrams are the most common type of investigative logic diagrams. On occasion, inductive diagrams (such as the ‘event tree’ shown in Figure 31.4) may be used to determine a most likely match between known facts and possible causes.
What is logic diagram with example?
The logic diagram consists of gates and symbols that can directly replace an expression in Boolean arithmetic. A logic gate is a device that can perform one or all of the Boolean logic operations AND, NAND, NOR, NOT, OR, XNOR, and XOR.
What are the two main types of computer network?
Two basic network types are local-area networks (LANs) and wide-area networks (WANs). LANs connect computers and peripheral devices in a limited physical area, such as a business office, laboratory, or college campus, by means of links (wires, Ethernet cables, fibre optics, Wi-Fi) that transmit data rapidly.
What is different types of network?
Personal Area Network (PAN) Local Area Network (LAN) Wide Area Network (WAN) Wireless Local Area Network (WLAN)
What is LAN MAN and WAN network?
LAN stands for Local Area Network. MAN stands for Metropolitan Area Network. WAN stands for Wide Area Network.
What is use of physical topology?
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.
What are the five main types of physical network topologies?
There are five types of topology – Mesh, Star, Bus, Ring and Hybrid.
Is Ethernet a logical topology?
The Ethernet operates on a logical bus topology. All the components on the network share the same medium and are detected based on the MAC address. Due to the shared component, the multiple components transfer at the time of data collisions.
