• If the hub, switch, or concentrator fails, nodes attached are disabled. • More expensive than linear bus topologies because of the cost of the hubs, etc. A tree topology combines characteristics of linear bus and star topologies. It consists of groups of star-configured workstations connected to a linear bus backbone cable (See fig. Tree topologies allow for the expansion of an existing network, and enable schools to configure a network to meet their needs. Tree topology Advantages of a Tree Topology • Point-to-point wiring for individual segments.
A logical topology describes how network devices appear to be connected to each other. For example, in a logical diagram of your office network, you may show a connection between city A and city B.
Data moves in only one direction around the ring till it arrives the destination. Network expansion A new cable is plugged in from the new node to the hub. In order to add a new node, a connection must be broken which turns down the network. Fault isolation Easy Difficult Troubleshooting The other nodes are affected only in the case of a hub failure. When a node goes down the information continues to transfer till the damaged node.
Or use it to upload your own PowerPoint slides so you can share them with your teachers, class, students, bosses, employees, customers, potential investors or the world. Or use it to create really cool photo slideshows - with 2D and 3D transitions, animation, and your choice of music - that you can share with your Facebook friends or Google+ circles.

Unlike the star network, the functionality of the central node may be distributed. As in the conventional star network, individual nodes may thus still be isolated from the network by a single-point failure of a transmission path to the node. If a link connecting a leaf fails, that leaf is isolated; if a connection to a non-leaf node fails, an entire section of the network becomes isolated from the rest. In order to alleviate the amount of network traffic that comes from broadcasting all signals to all nodes, more advanced central nodes were developed that are able to keep track of the identities of the nodes that are connected to the network. These will 'learn' the layout of the network by 'listening' on each port during normal data transmission, examining the and recording the address/identifier of each connected node and which port it's connected to in a held in memory.
Advantages ▶ It is very easy to install and manage the star network topology, as it is the simplest of the lot when it comes to functionality. ▶ It is easy to troubleshoot this network type, as all computers are dependent on the central hub which invariably means that any problem which leaves the network inoperable can be traced to the central hub. ▶ In star network topology, data packets don't have to make their way through various nodes. The fact that there is no data collision adds to its performance by making data transfer considerably fast. ▶ Also, the fact that data packets only make it through three different points ensures that the data is safe. ▶ As the nodes are not connected to each other, any problem in one particular node doesn't hamper the performance of other nodes in the network.

Partial mesh topology uses fewer connections, and though less expensive is also less fault-tolerant. In a hybrid mesh the mesh is complete in some places but partial in others. Full mesh is generally utilized as a backbone where there are few nodes but a great need for fault tolerance, such as the backbone of a telecommunications company or ISP. Partial and hybrid meshes are usually found in peripheral networks connected to a full-mesh backbone. The primary advantage of this topology is that it is highly fault tolerant: when one node fails, traffic can easily be diverted to other nodes. It is also not especially vulnerable to bottlenecks.
The term 'network topology' refers to the layout of a network. Due to the specific nature of computer network technology, networks must be arranged in a particular way in order to work properly. These arrangements are based on the network hardware's capabilities and the characteristics of the various modes of data transfer. Because of these factors, network topologies are further subdivided into two categories: physical topologies and logical topologies. Physical Topologies The physical topology of a LAN refers to the actual physical organization of the computers on the network and the subsequent guided transmission media connections. Physical topologies vary depending on cost and functionality.
