What are the advantages and disadvantages of a star network?

star network topology advantages and disadvantages

Star is a basic computer network topology in which all nodes computers and peripheral devices of the network are connected to the central hub or switch with a point-to-point connection, forming a physical network segment. Use of terminators is must. Star topology: In this type of network, a central computer usually forms the main node and the subsidiary nodes are connected to it and to each other through a or hub. The is mostly a mainframe computer while other nodes in the hierarchy are mini or microcomputers. The concept is further categorized into two types: i physical topology, which refers to the physical design of a network, and ii logical topology, which focuses on how the data is actually transferred within the network.

Disadvantages Drawbacks of Linear Bus Topology 1 There is a limit on central cable length and number of nodes that can be connected. A star topology is a in which all the network nodes are individually connected to a central switch, hub or computer which acts as a central point of communication to pass on the messages. Now-a-days Hubs are often replaced by Fast Network Switches. This video illustrates how data is transmitted and shared between computers in a star network topology. To obtain additional range, repeaters or additional access points will have to be purchased.

It helps in monitoring the network. All the nodes in the network then receive the message but the node for which it was actually sent only processes it. Star Topology Star Topology is the most common type of network topology that is used in homes and offices. Similarly components can also be removed easily. It also acts as a repeater for the data flow. On the other hand, if the ring topology is connected to the bus topology then the resulting topology is called the hybrid topology. Obviously, the advantages and disadvantages of a hybrid topology are a combination of the merits and demerits of the topologies used to structure it.

After covering and under different types of network topologies in previous articles, the time has come when we move forwards to the star network topology. For example, if we have four computers, we must have six links. Figure 6 shows a typical arrangement of computers in hybrid topology. Star networks are one of the most common computer. It is relatively less expensive than a star topology network. Tree topology is the next topic we are going to discuss in our. High traffic increases load on the bus, and the network efficiency drops.

In tree topology, nodes of the underlying bus network topology are replaced with a complete star topology. Figure 4 shows the arrangement of computers in the ring topology. Network topology refers to the physical layout of the network in which all the devices are connected. The hierarchical topology is symmetrical, having a fixed branching factor, f, associated with each node. The bus has terminators at either end which absorb the signal, removing it from the bus.

When a node wants to send a message to the other nodes, it first sends the message to the hub, which in turn forwards the message to the intended node. Its failure affects the entire network. Main Types of Physical Topologies The following sections discuss the physical topologies used in networks and other related topics. High traffic increases load on the bus, and the network efficiency drops. On the other hand, Switch sends data only to the destination computer.

In this article we will see the various types of Network topologies with their advantages and disadvantages. Logical topology was discussed in the Protocol chapter. When the number of devices connected to the bus increases, the efficiency decreases. The most common cable in schools is unshielded twisted pair, which is most often used with star topologies. This isolation also prevents any non-centralized failure from affecting the network. Each resulting hybrid topology has its own features, advantages and limitations of its components. A central server is not required for the management of this topology.

Thus, with the use of a high-capacity central hub, traffic load can be handled at fairly decent speeds. Short Bytes: Star Topology is the most commonly used network topology. Nothing herein shall be construed as a recommendation to use any product or service in violation of existing patents or rights of third parties. The network adopts the characteristics and functioning of the combined topologies,rather than just the one. Thus, failing of one segment does not affect the rest of the network.

At the same time its easy to detect the failure and troubleshoot it. ? A tree topology combines characteristics of linear bus and star topologies. Figure 1 shows the arrangement of computers in hierarchical topology. Know and learn more about the star topology. However, as with the simple variant of star topology, the cost incurred on the added infrastructure can be a disadvantage. Suppose, computer A needs to send data to computer D. Bus line topology: Nodes are connected to a main bus cable.
