What is the logical topology of a physical star topology?

Physical Star Logical Ring With one physical path, the topology is called a single ring, and with two physical paths, the topology is called a dual ring.

What is a logical star topology?

An Ethernet network connected using a switch has a logical star topology. Messages are sent only to the intended device an no other. A Token Ring network connects all devices into a physical star through a device called a multi-station access unit (MAU).

What is the main disadvantage of a physical star topology?

Requires more cable length than a linear bus topology. If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.

What are physical topologies?

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 examples of physical topology?

Top 7 Types of Physical Topology

  • P2P Topology. The network that direct links two computers are called point to point topology. …
  • Bus Topology. A single cable is used to connect all the nodes in this topology. …
  • Ring Topology. …
  • Star Topology. …
  • Mesh Topology. …
  • Tree Topology. …
  • Hybrid Topology.

What is the difference between logical and physical topology?

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 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.

Why is a physical mesh topology normally an impractical solution?

Why is the Physical mesh topology normally an impractical solution ? Because the number of Connections increase with every new node that is added to the network. what are the advantages of the logical star topology over the logical bus topology? … How do hosts on a Physical ring topology Communicate ?

What is extended star topology?

A hierarchical or extended star topology is a star network with an additional networking device connected to the main networking device. Typically, a network cable connects to one switch, and then several other switches connect to the first switch.

Which topology is most fastest topology?

Data can be transferred at fastest speed in star topology .

What is the example of star topology?

Star Network Topology Star network topologies are common in home networks, where the central connection point may be a router, switch, or network hub. Unshielded Twisted Pair (UTP) Ethernet cabling is typically used to connect devices to the hub, though coaxial cable or optical fiber may also be employed.

What are the main reason behind the popularity of star topology explain each of them in detail?

The star and extended star are the most popular topologies for Ethernet networks. This type network is easy to setup, relatively inexpensive, and provides more redundancy than other topologies, i.e. bus topology. The star topology is configured by connecting all of the nodes on the network to central device.

What is advantage and disadvantage of star topology?

Comparison Table for Advantages & Disadvantages of Star Topology

Advantages Disadvantages
Highly efficient Expensive
Centralized network management Requires additional equipment
Safe to use Immobile systems
No point-to-point connections Wires or cables used in the network get damaged easily

What is the difference between a hub and a switch?

Hub and Switch are both network connecting devices. Hub works at physical layer and is responsible to transmit the signal to port to respond where the signal was received whereas Switch enable connection setting and terminating based on need. Switch works in Data Link Layer. …

How many types of physical topologies are there?

Geometric representation of how the computers are connected to each other is known as topology. There are five types of topology Mesh, Star, Bus, Ring and Hybrid.

What is the most commonly used physical topology?

Star topology Star topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cablethus creating a star-like shape. All data must travel through the central node before it reaches its destination.

Which type of physical topology is more reliable?

Mesh topologies are reliable and stable, and the complex degree of interconnectivity between nodes makes the network resistant to failure. For instance, no single device going down can bring the network offline.

What is the physical topology of the Internet?

[1] 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.

Why is physical topology rarely used?

Also, because you have to ‘break’ the ring in order to add another station, it is very difficult to reconfigure without bringing down the whole network. For this reason, the physical ring topology is seldom used.

Is ring topology physical or logical?

The ring topology is actually a logical ring, meaning that the data travels in circular fashion from one computer to another on the network. It is not a physical ring topology. Figure 4 shows the logical layout of a ring network.

What is the difference between logical and physical 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 are examples of logical topology?

Logical network topology examples include twisted pair Ethernet, which is categorized as a logical bus topology, and token ring, which is categorized as a logical ring topology.

What is a logical 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 does logical mean in technology?

Webopedia Staff. (1) Refers to a user’s view of the way data or systems are organized. The opposite of logical is physical, which refers to the real organization of a system. For example, a logical description of a file is that it is a collection of data stored together.

What is the most common physical topology found in LANs today?

Star. Star topology has become the dominant physical topology for LANs.

Which physical topology will make a cable break to prevent?

-A malfunctioning node or cable break can prevent signals from reaching nodes further along the ring. A star topology uses a hub or switch to concentrate all network connections to a single physical location. Today it is the most popular type of topology for a LAN.

Why it is possible for the physical and logical topologies of a network to be different?

Physical topology indicates arrangement of different elements of a network. … Difference between Physical and Logical Topology :
