Which topology is commonly used and why?
The star topology is the most common network topology used nowadays for the many advantages it provides. This topology requires a centralized unit, which is called a switch, and all other network devices are connected to this switch with own network cable.
What are the types of logical topology?
Logical Topology: The logical topology of a network determines how the hosts communicate across the medium. The two most common types of logical topologies are broadcast and token passing. The use of a broadcast topology indicates that each host sends its data to all other hosts on the network medium.

Bus network topology. ... Ring network topology. ... Star network topology. ... Mesh network topology. ... Tree network topology. ... Hybrid network topology.
What are the 3 types of network topology?
The Different Types of Network TopologiesBus topology. As the simplest design, a bus topology requires nodes to be in a linear order. ... Ring topology. Another simple design is the ring topology. ... Star topology. Unsurprisingly, a star topology's setup resembles, well, a star. ... Mesh topology. ... Tree topology.
Which is the best topology?
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 the most common network topology?
Star topologyStar topology is by far the most common. Within this framework, each node is independently connected to a central hub via a physical cable—thus creating a star-like shape. All data must travel through the central node before it reaches its destination.
What is physical topology?
The term physical topology refers to the way in which a network is laid out physically input/output or more devices connect to a link; two or more links form a topology.
What is topology in computer networking?
The term topology in computer networking refers to the way in which a network is laid out physically. Two or more devices connect to a link; two or more links form a topology. The topology of a network is the geometric representation of the relationship of all links and linking devices (usually called nodes) to one another.
What is network topology?
Network Topology is the schematic description of a network arrangement, connecting various nodes (sender and receiver) through lines of connection.
Which is less expensive, a star topology or a mesh topology?
A star topology is less expensive than a mesh topology.
How many levels of hierarchy should a node have?
It has a root node and all other nodes are connected to it forming a hierarchy. It is also called hierarchical topology. It should at least have three levels to the hierarchy.
What is dedicated mesh topology?
In a mesh topology, every device has a dedicated point-to-point link to every other device. The term dedicated means that the link carries traffic only between the two devices it connects.
Is a bus topology multipoint?
The preceding examples all describe point-to-point connections. A bus topology, on the other hand, is multipoint. One long cable acts as a backbone to link all the devices in a network.
What is topology in computer science?
topology is a pattern in which computers are connected to each other .
What is the point to point topology?
Point-to-point topology is the simplest of all the network topologies. The network consists of a direct link between two computers. This is faster and more reliable than other types of connections since there is a direct connection. The disadvantage is that it can only be used for small areas where computers are in close proximity.
What is bus topology?
Bus topology uses one main cable to which all nodes are directly connected. The main cable acts as a backbone for the network. One of the computers in the network typically acts as the computer server. The first advantage of bus topology is that it is easy to connect a computer or peripheral device. The second advantage is that the cable requirements are relatively small, resulting in lower cost.
What is the layout pattern of the interconnections between computers in a network called?
The layout pattern of the interconnections between computers in a network is called network topology. You can think of topology as the virtual shape or structure of the network. Network topology is also referred to as 'network architecture.'
How does ring topology work?
In ring topology, the computers in the network are connected in a circular fashion, and the data travels in one direction. Each computer is directly connected to the next computer, forming a single pathway for signals through the network. This type of network is easy to install and manage.
Why is star topology so popular?
Star topology is very popular because the startup costs are low. It is also easy to add new nodes to the network. The network is robust in the sense that if one connection between a computer and the hub fails, the other connections remain intact. If the central hub fails, however, the entire network goes down. It also requires more cable than bus topology and is, therefore, more expensive.
What are the disadvantages of a topology?
One of the disadvantages is that if the main cable breaks, the entire network goes down. This type of network is also difficult to troubleshoot. For these reasons, this type of topology is not used for large networks, such as those covering an entire building.

What is bus topology?
Bus topology is the simplest kind of topology in which a common bus or channel is used for communication in the network. The bus is connected to various taps and droplines. Taps are the connectors, while droplines are the cables connecting the bus with the computer. In other words, there is only a single transmission line for all nodes.
What is deterministic network topology?
This network topology is deterministic in nature, i.e., each computer is given access for transmission at a fixed time interval. All the nodes are connected in a closed-loop. This topology mainly works on a token-based system and the token travels in a loop in one specific direction.
What is logical topology?
Logical Topology: A logical topology describes the way, data flow from one computer to another. It is bound to a network protocol and defines how data is moved throughout the network and which path it takes. In other words, it is the way in which the devices communicate internally. Network topology defines the layout, virtual shape, ...
