Topology defines the structure of the network of how all the components are interconnected to each other. There are two types of topology: physical and logical topology. CSMA: It is a media access control used to control the data flow so that data integrity is maintained, i.

What is Topology?

Network topologies describe the methods in which all the elements of a network are mapped. The topology term refers to both the physical and logical layout of a network. In this network topology tutorial, we will explain: What is Topology? Types of Networking Topologies Two main types of networking topologies are 1 Physical topology 2 Logical topology Physical topology: This type of network is an actual layout of the computer cables and other network devices Logical topology: Logical topology gives insight's about network's physical design.

In this method, the network consists of a direct link between two computers. P2P Topology Diagram Advantages: This is faster and highly reliable than other types of connections since there is a direct connection.

No need for a network operating system Does not need an expensive server as individual workstations are used to access the files No need for any dedicated network technicians because each user sets their permissions Disadvantages: The biggest drawback is that it only be used for small areas where computers are in close proximity.

You can't back up files and folders centrally There is no security besides the permissions. Users often do not require to log onto their workstations. Bus Topology Bus Topology Diagram Bus topology uses a single cable which connects all the included nodes.

The main cable acts as a spine for the entire network. One of the computers in the network acts as the computer server. When it has two endpoints, it is known as a linear bus topology. Famous for LAN network because they are inexpensive and easy to install. It is widely used when a network installation is small, simple, or temporary.

It is one of the passive topologies. So computers on the bus only listen for data being sent, that are not responsible for moving the data from one computer to others. When network traffic is heavy, it develops collisions in the network. Whenever network traffic is heavy, or nodes are too many, the performance time of the network significantly decreases.

Cables are always of a limited length. Ring Topology Ring Topology Diagram In a ring network, every device has exactly two neighboring devices for communication purpose.

It is called a ring topology as its formation is like a ring. In this topology, every computer is connected to another computer. Here, the last node is combined with a first one. This topology uses token to pass the information from one computer to another. In this topology, all the messages travel through a ring in the same direction.

Adding or deleting a device in-ring topology needs you to move only two connections. The troubleshooting process is difficult in a ring topology. Failure of one computer can disturb the whole network. Offers equal access to all the computers of the networks Faster error checking and acknowledgment. Break in a single ring can risk the breaking of the entire network Modern days high-speed LANs made this topology less popular. In the ring, topology signals are circulating at all times, which develops unwanted power consumption.

It is very difficult to troubleshoot the ring network. Adding or removing the computers can disturb the network activity. Star Topology Star Topology Diagram In the star topology, all the computers connect with the help of a hub. This cable is called a central node, and all other nodes are connected using this central node. It is most popular on LAN networks as they are inexpensive and easy to install.

Only those nodes are affected, that has failed. Other nodes still work. Fast performance with few nodes and very low network traffic. In Star topology, addition, deletion, and moving of the devices are easy. Cost of installation of star topology is costly.

Heavy network traffic can sometimes slow the bus considerably. Performance depends on the hub's capacity A damaged cable or lack of proper termination may bring the network down. Mesh Topology The mesh topology has a unique network design in which each computer on the network connects to every other.

It is develops a P2P point-to-point connection between all the devices of the network. It offers a high level of redundancy, so even if one network cable fails, still data has an alternative path to reach its destination.

Types of Mesh Topology: Partial Mesh Topology: In this type of topology, most of the devices are connected almost similarly as full topology.

The only difference is that few devices are connected with just two or three devices. Need extra capable compared with other LAN topologies. Complicated implementation. No traffic problem as nodes has dedicated links.

It has multiple links, so if any single route is blocked, then other routes should be used for data communication. P2P links make the fault identification isolation process easy. It helps you to avoid the chances of network failure by connecting all the systems to a central node.

Disadvantages: Installation is complex because every node is connected to every node. Dedicated links help you to eliminate the traffic problem. A mesh topology is robust.

Every system has its privacy and security It is expensive due to the use of more cables. No proper utilization of systems. It requires more space for dedicated links. Because of the amount of cabling and the number of input-outputs, it is expensive to implement. It requires a large space to run the cables. Tree Topology Tree Topology Tree topologies have a root node, and all other nodes are connected which form a hierarchy. So it is also known as hierarchical topology.

This topology integrates various star topologies together in a single bus, so it is known as a Star Bus topology. Tree topology is a very common network which is similar to a bus and star topology. Node expansion is fast and easy.

Hybrid Topology Hybrid Topology Hybrid topology combines two or more topologies. You can see in the above architecture in such a manner that the resulting network does not exhibit one of the standard topologies.

For example, as you can see in the above image that in an office in one department, Star and P2P topology is used. A hybrid topology is always produced when two different basic network topologies are connected. Here are some important considerations for selecting the best topology to create a network in your organization: Bus topology is surely least expensive to install a network.

If you want to use a shorter cable or you planning to expand the network is future, then star topology is the best choice for you. Fully mesh topology is theoretically an ideal choice as every device is connected to every other device. If you want to use twisted pair cable for networking, then you should build star topologies.

What Is Network Topology And Types Of Topology Pdf

Network topology is the schematic description of the arrangement of the physical and logical elements of a communication network. Network topology refers to the manner in which the links and nodes of a network are arranged to relate to each other. Topologies are categorized as either physical network topology, which is the physical signal transmission medium, or logical network topology, which refers to the manner in which data travels through the network between devices, independent of physical connection of the devices. 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. 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. A network topology diagram helps visualize the communicating devices, which are modeled as nodes, and the connections between the devices, which are modeled as links between the nodes.

Bus Single cable connects everything. Ring Single cable configured in a ring. Information Transfer All information passes through the central network connection.

Network topology is the layout of the connections links , nodes , etc. The names used - such as ring or star - are only rough descriptions. The computers on a home network can be arranged in a circle but it does not necessarily mean that it represents a ring network.

Network Topology Comparison

Network Topology

Network topology is the arrangement of the elements links , nodes , etc. Network topology is the topological [4] structure of a network and may be depicted physically or logically. It is an application of graph theory [3] wherein communicating devices are modeled as nodes and the connections between the devices are modeled as links or lines between the nodes. Physical topology is the placement of the various components of a network e. Distances between nodes, physical interconnections, transmission rates , or signal types may differ between two different networks, yet their logical topologies may be identical.

Он не мог понять, куда она подевалась. Всякий раз включался автоответчик, но Дэвид молчал. Он не хотел доверять машине предназначавшиеся ей слова. Выйдя на улицу, Беккер увидел у входа в парк телефонную будку. Он чуть ли не бегом бросился к ней, схватил трубку и вставил в отверстие телефонную карту. Соединения долго не .


Ring Topology. • Logical ring. – Meaning that data travels in circular fashion from one computer to another on the network. – Typically FDDI, SONET or Token.
