What Is True Concerning Physical And Logical Topologies?

What is true concerning physical and logical topologies?

• Both of the topology logical and physical are the same.
• Physical topology is related to how the frames are transferred through the network.
• The physical topology shows the IP address schedule of the networks.
• Logical topology is concerned with how the network transfers data between devices. 

Answer: the physical topology work is to display the interconnection between the devices physically while the logical topology displays the method the network will move the data among the connected nodes.

Physical topology:

The physical topology work is to manage or form the order of different components of the network. The physical connection with the help of wire technology such as cables made the connected network. The main focus of network topology is to focus on the general elements such as the data transfer, type of the device, etc. The structure of the wire and nodes connection depends on how easy the installation and the network setup are? The cost and the capability of the bandwidth are also affected based on the devices. The node’s location and distance among them also matter to physical topology. The device arranges also form like a ring, or in the form of a straight line like bus topology. Factors that affect the connection of the physical topology are :

• Cost
• Scalability
• Installation
• Bandwidth capability.

Types of the physical topology are also listed below:

• Bus topology.
• Ring topology.
• Star topology.
• Mesh topology.

Logical topology:

The logical topology shows the structure of the devices and the communication among them.it reflects how the data is transferred through the physical topology. It does not depend on physical topology, except the structure of the node as how they are arranged? It focuses on the tangled detail of the network such as the type of devices (switches, hubs, router) and their quality which has an impact on the transfer rate and speed of the data frames. The logical topology ensures exquisite flow which is moving within the network. The types of logical topology are:

• Logical bus: The data transfer in the liner method.
• Logical ring: The data transfer in the ring form.

The logical topology deal with the logical connection so it can handle a few things such as:

• The discipline of the lines.
• Deliver order.
• The alarm of the error.
• Exquisite flow control.

The main difference between the physical and logical topology

 The major difference between physical and logical topology are discussed below:

• The physical topology shows the physical layout while logical topology is the logical connection that shows the transmission of the data among physical topology.
• The structure can change based on need in physical topology while in logical topology no modification or changes can happen.
• Physical topology structure is start ring, mesh, and bus topology .in the logical topology is logical bus and ring.
• Physical topology is the actual connection while logical topology shows the data flow.
• Physical topology affects the cost, bandwidth, of the network based on the availability of the network. Logical topology affects the speed and the data transmission flow.
