What is the difference between a logical network and a physical network?
A physical network connects two or more physical network interfaces. 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.
Which topology is best in networking?
A full mesh topology provides a connection from each node to every other node on the network. This provides a fully redundant network and is the most reliable of all networks. If any link or node in the network fails, then there will be another path that will allow network traffic to continue.
What are the advantages of a logical star topology over the logical bus 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 is logical topology in networking?
A logical topology is a concept in networking that defines the architecture of the communication mechanism for all nodes in a network. Logical topologies contrasts with physical topologies, which refer to the physical interconnections of all devices in the network.
What is logical topology and its types?
Logical Topology is the arrangement of network devices and nodes to form a logical or physical structure. There are two types of topologies that are logical and physical. The logical topology deals with network protocols that are used to control the data flow across the network.
Which topology is faster?
star topology
6. Data transmission is faster in star topology. In Bus topology the data is transmitted slower as compared to star topology.
What is the example of logical topology?
For 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 a star topology.
What are the 5 basic components of data communication?
The different components of Data communication are shown in the following figure.
- Message: The message is the information (data) to be communicated.
- Sender: The sender is the device that sends the data message.
- Receiver: The receiver is the device that receives the message.
- Transmission medium:
- Protocol:
