Type of network topology pdf

Internet is the key technology in the present time, and it depends upon the network topology. There are several types of topology available such as bus topology, ring topology, star topology, tree topology, point-to-multipoint topology, point-to-point topology, worldwide-web topology.

Local area network LAN and Wide area network WAN are the commonly used network topology that is installed and configured in the enterprise.

Some of the advantages of implementing network topology are proper functioning of a network, upgrading network performance, Reduces operational, implementation and maintenance cost, error or fault detection, effective utilization of resources. Basically, it is made from two words, Network and Topology. Network — Network is an arrangement where two or more computers also referred to as nodes communicate with each other.

These computers or participants nodes actively contribute to the process of communication. Topology — Topology is simply an arrangement of how these nodes will interact. It is a topology that governs data flow between respective nodes. Hence, it is an arrangement of two or more nodes communicating with each other, typically over the internet through a particular medium.

Tree topology is the topology in which the nodes are connected hierarchically, with all the nodes connected to the topmost node or root node. Hence, it is also known as hierarchical topology. Tree topology has at least three levels of hierarchy. Tree topology is applied in Wide Area Network. It is an extension of Bus topology and Star topology. It is best if the workstations are situated in groups, for easy working and managing. Hybrid Topology is basically a network topology comprising of two or more different types of topologies.

It is a reliable and scalable topology, but simultaneously, it is a costly one. It receives the merits and demerits of the topologies used to build it. We have seen the various network topologies available to us, along with their benefits and drawbacks. According to our requirements, it will now be easy for us to choose which network topology can be used.

This has been a guide to Types of Network Topology. Here we discuss 8 network types of topology with their respective benefits and drawbacks. You can also go through our other suggested articles to learn more —. So cable lengths, distance between nodes, location of servers, etc.

Failure of one node or a segment of cabling should not render the whole network useless. Data network with bus topology has a linear transmission cable , usually coaxial , to which many network devices and workstations are attached along the length. Server is at one end of the bus. Topology is derived from two Greek words topo and logy, where topo means 'place' and logy means 'study'. In computer networks, a topology is used to explain how a network is physically connected and the logical flow of information in the network.

A topology mainly describes how devices are connected and interact with each other using communication links. Network topology defines the layout, virtual shape, or structure of the network, not only physically but also logically. A network can have one physical topology and multiple logical topologies at the same time.

Network topologies describe the ways in which the elements of a network are mapped. They describe the physical and logical arrangement of the network nodes. Different Types of Topologies. But it leads to a complex design and increase in installation work.

Token Passing: Every packet of information sent contains It sometimes increase cost due to need of hub that can work a specific address by the source called token. By the help with different architecture. It need large costly infrastructure, of these tokens computers in between the source and the cooling and cabling. It happens until the packet reaches its destination. Tree Topolgy Tree topology sometimes referred as hierarchical topology Ring topology is a very cheap and very easy for installation is a most common kind of hybrid topology made up of as compared to other topologies while its upgrade procedure Star and bus topology.

It contains levels of hierarchy with is difficult and affects the entire network. There is very less a root node or central level. Its branching factor is independent of total number of devise in Topologies define both Physical and Logical view of the the network. The total number of point to point connections network.

They can be same or different. Network Topology are one lesser then the total number of hardware elements. In determines what kind of functions it can perform and what the relative comparison of nodes performance those nearer to quality of communication it do. It is not necessary that logical root performs better than those far from it. The choice of Topology depends on factor such as Cost, This topology is widely used as compared to others. It Expansion, Security, and Bandwidth Capacity, Delay or data provides a benefit of point to point connection of individual flow efficiency, ease of fault finding and many more [1].

This topology is bit difficult to configure and This in turns impacts Equipment requirement, Capability of reliability depends on backbone line.

Equipment, network management and growth. Table-1 shows the relative comparison of how different topologies perform for different factors. Networks in work places usually implement Bus Topology. There are many other hybrid topolo- gies like Fat-Tree, Dragon Fly etc. It is not always possible to implement a low cost, high performance, highly reliable and secure hybrid topology in every network.
