The point-to-point connections make it easier for maintenance personnel to locate damaged segments. Owing to its size and complexity, maintenance is not easy and costs are high. Each branch contains Star Network. Tree Topology Advantages and Disadvantages. Each Switch or Bus further connects to one or more Net… A tree topology relies heavily on its main bus cable. The only thing that’s necessary is to run a connection cable to the new terminal or peripheral from the existing connection. If there are multiple networks that require a connection, then a line comes from the primary cable to create a space with central nodes that connect to each other and the other terminals in their space. That means less time gets spent from a maintenance standpoint trying to find where a fault occurs. 2. Error & fault detection in tree topology is easy. It is a common way to organize corporate networks and information stored in a database. This disadvantage can become quite problematic if the incident occurs in the backbone cable. That gives users the benefits of local use and the flexibility to use other systems when there are enough data packets on the network to create a traffic jam. That’s why this option is the most difficult to configure and wire when looking at the other topologies. Also, configuration is difficult in comparison to that in other topologies. 4. Tree topology is the combination of star and bus topology. Tree topology performs remarkable with large networks. If one terminal doesn’t have network access, then investigators can look to see if the next link in the connection chain does. That means there can only be a maximum of five segments between any two nodes, connected through four repeaters or concentrators. 3. The tree topology design derives its foundation from star and bus topologies. The parent-child connections it creates can be useful in some situations, but it can be a costly experience since it requires a massive amount of cabling for proper installation. Data transfer quality of Ethernet is pretty good. In this arrangement, the node at each level could be forming a star network with the nodes it serves. If several star or bus topologies already exist, then a tree topology can form by running a single backbone cable that connects them all. It is sometimes referred to as a star bus topology because elements of both options are found in the design of a tree topology. The stars can have their own printers that the one “branch” off of the backbone cable uses. In tree network topology, star networks are interconnected with each other with the help of bus network. Basic Networking; Tree Topology Network is a combination of the bus and the Star Network. This is basically a hybrid topology. 7. When a tree topology remains at a manageable size, then finding an error in the system is rather simple. You can simply attach new computers to hub or switch. Because you’re using star and bus configuration principles when designing a tree topology with linear characteristics, this option tends to be the most difficult installation process of any topology system. As multiple segments are connected to a central bus, the network depends heavily on the bus. Even if less space is available, you can extend the Star Network for creating more space. There can be security issues with a tree topology. Tree topology is noticeably important to establish communication between two networks. 2. Requires large number of cables; the establishment cost increases as well. The topology establishes a natural child & parent hierarchy. Advantages of Tree Topology. Physical security options at the front door can also limit unauthorized access. The parent node extends towards leaf nodes in next level of hierarchy. Then the workstations connect to a hub that serves as the link to the backbone cable. 4. It takes more time to maintain the point-to-point connections, investigate faults, and manage the individual stars. Scalability of the network depends on the type of cable used. Although it is an uncommon design that gets used for networks today, it is still an option to consider in specific circumstances when hierarchical communication and scalability are necessary between two or more networks. Tree Topology Advantages and Disadvantages. 5. This protocol is usually resistant to noise. A tree topology is a special type of structure where many connected elements are arranged like the branches of a tree. The central HUB plays the role of data center or network control. It is a useful design for when the other two options don’t have the same ability to reach scalability because it creates an alternative that uses existing resources. Disadvantages of Tree Topology 1. Tree Topology is very much reliable. As long as one connection exists, the new line can expand the reach of the network by creating another simple point of access. You can run that line from the backbone, a hub, or to another terminal or peripheral. Star topology exhibits two level of hierarchy whereas tree topology exhibits three level of hierarchy. The expansion of the network is possible through a simple process. In terms of star-bus topology, multiple nodes are connected through one edge ways connection. Expansion & contraction of tree network is really flexible. If a break happens before the rest of the branches of the tree topology, then the entire system won’t function correctly – even though everyone could still communicate with each other on the other side of the fault. Although a problem in the backbone cable can be a challenge to find on large systems, the divided network into star systems and hubs still creates a trail of breadcrumbs to follow. Advantages of Tree Topology 1. Tree topologies must usually follow the 5-4-3 rule. Because the cabling requirements of the tree topology incorporate star and bus requirements, the initial investment is going to be extensive. Each star can operate independently from the rest of the network as needed, or it can connect directly to the rest of the system to facilitate communication or collaboration. Cost is often the limiting factor when deciding what topology to use. Only one connection exists between two connected nodes. For example, tree topologies are frequently used to organize the computers in a corporate network, or the information in a database. Both coaxial & twisted pair cable use copper insulation wiring. Backbone appears as the failure point of the entire segment. So in terms of future expansion of network, tree is a good choice with no doubt. Networking concepts are better understood with network topology. Network topology acts as an important factor to choose what the media type should be used to cable a network. That means the businesses that use tree topology designs must incorporate password protections and other workstation-based security protocols to limit information access. 2. Most people can remain productive on their local system while the maintenance work occurs, reducing productivity gaps. A tree topology is a structure type where computers, terminals, servers, and peripherals get connected in a shape that’s reminiscent of branches on a tree. In fact a computer program itself utilizes tree topology. Unlike Bus Topology you don`t need to puncture the main backbone cable for adding computers. Searching & sorting operation of large amount of data demands for binary tree use. This segmentation makes it easier to assign personnel to inspect problems or provide help desk responsibilities. If the computer in first level (highest level) is erroneous, next level computer will also go under problems. As more and more nodes and segments are added, the maintenance becomes difficult. The top-level node is mostly a mainframe computer while other nodes in the hierarchy are mini or microcomputers.

Binary tree is the special kind of tree where each parent (node) has maximum two children. You’re naturally limited in each segment length to the type of cabling used to create the system in the first place. it’s covers up the limitation of star topology. Topology is the a schematic representation of network Generally tree topology is the integration of star topology and bus topology. If one segment gets damaged, the rest of the network remains unaffected. Database systems like PostgreSQL, MySQL, & Redis & file systems like NTFS, HFS+, and Ext4 widely use tree topology.
