Physical Topology means the physical layout of the network. 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.

What is the difference between 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 the difference between physical topology and logical topology quizlet?
Physical topologies refer to the physical layout of devices and network media. Logical topologies refer to the logical paths in which data accesses the media and transmits packets across it.
What is a logical topology?
What Does Logical Topology Mean? 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 a physical 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 is physical and logical network diagram?
A physical network diagram depicts the network topology with the physical aspects like ports, cables, racks, and more. A logical network diagram, on the other hand, shows the “invisible” elements and connections flowing through the physical objects on the network.
What is meant by logical and physical networks?
A logical network is a portion of a physical network that connects two or more logical network interfaces or devices. A logical network interface or device is the software entity that is known by an operating system.
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 characteristics of a physical network topology?
Key features of network topology Nodes: In networking, nodes refer to connection points, redistribution points and communication endpoints. Cables: The physical network topology consists of several types of cables and equipment, including coaxial cables, twisted pair cables and optical fiber cables.
What advantages of the logical star topology have as compared to the logical bus topology?
what are the advantages of the logical star topology over the logical bus topology? – All the data goes through the central point Which can be equipped with diagnostic devices Which makes it easy to troubleshoot.
What are the advantages of the logical star topology?
Advantages of Star Topology Less expensive because each device only need one I/O port and wishes to be connected with hub with one link. Easy fault detection because the link are often easily identified. No disruptions to the network when connecting or removing devices.
What are types of logical topology?
Logical Topologies. The two logical topologies are broadcast (also known as bus) and sequential (also known as ring).
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 are some examples of physical topology?
Physical network topology examples include star, mesh, tree, ring, point-to-point, circular, hybrid, and bus topology networks, each consisting of different configurations of nodes and links.
What is a logical network?
What is a logical network? A logical network is one that appears to the user as a single, separate entity although it might in fact be either an entity created from mutliple networks or just a part of a larger network. A logical network is defined by its IP addressing scheme.
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.
What is the difference between a logical and physical data flow diagram?
The main difference between Logical DFD and Physical DFD is that Logical DFD focuses on business and related activities while Physical DFD focuses on how the system is implemented. Data Flow Diagram (DFD) explains the flow of data of an information system.
What is the difference between physical interface and logical interface?
Each interface has two types of properties assigned to it: physical properties and logical properties. Physical properties are tied to the entire physical port, whereas logical properties affect only that logical portion of the interface represented by unit numbers or channel numbers.
Which topology is best?
The best cabled network topology for large businesses is the star topology. This is because it is easier to control from a central console as the management software just needs to communicate with the switch to get full traffic management features.
What is physical topology and its types?
Physical Topologies. 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.
Which network topology is faster?
Data transmission is faster in a star topology. In a Bus topology, the data is transmitted slower as compared to a star topology. 8.
Which topology has the highest reliability?
Mesh topology: In this, each device has a dedicated point to point link to every other device. Dedicated means that a link carries traffic only between two devices it connects. It is the most reliable topology.
Which topology is the most secure?
A DMZ is the most common and secure firewall topology. It is often referred to as a screened subnet. A DMZ creates a secure space between your Internet and your network, as shown in Figure D.
Which topology is used in Internet?
For Example, the Internet(WAN), etc. Following are the advantages of Mesh topology: Dedicated links facilitate direct communication. No congestion or traffic problems on the channels.
What is difference between hub and switch?
Hub and Switch are the network connecting devices, both help to connect various devices. Hub works at the physical layer and transmits the signal to the port. Switch route the information and send it over the network.
