The hub or switch acts as a middleware between the nodes. Star topology is a computer network topology in which all the nodes are connected to a centralized hub.

Difficult to reconfigure(we have to break the ring).

Slow data transmission speed(each message has to go through the ring path).

If a node fails, the whole network will fail.

Easy to troubleshoot(the faulty node does not pass the token).įollowing are the disadvantages of Ring topology:.

Reduces chances of data collision(unidirectional).

Following are the advantages of Ring topology:

When this token reaches the destination node, the data is removed by the receiver and the token is made free to carry the next data.įor Example, Token Ring, etc. In a ring topology, if a token is free then the node can capture the token and attach the data and destination address to the token, and then leaves the token for communication. This topology mainly works on a token-based system and the token travels in a loop in one specific direction. All the nodes are connected in a closed-loop. This network topology is deterministic in nature, i.e., each computer is given access for transmission at a fixed time interval. The message passing is unidirectional and circular in nature. Ring topology is a topology in which each computer is connected to exactly two other computers to form the ring. Congestion and traffic on the bus as it is the only source of communication.Security issues and risks are more as messages are broadcasted to all nodes.A limited number of nodes can connect to the bus due to limited bus length.If the bus fails, the network will fail.Efficiency is less when nodes are more(strength of signal decreases).If a node fails, it will not affect other nodes.įollowing are the disadvantages of Bus topology:.Following are the advantages of Bus topology: The devices share the responsibility for the flow of data from one point to the other in the network.įor Example Ethernet cable, etc. Every computer can share the network's total bus capabilities.

In a bus topology, each computer communicates to another computer on the network independently. The data is sent only in one direction and as soon as it reaches the end, the terminator removes the data from the communication line(to prevent signal bounce and data flow disruption).

Both ends of the shared channel have line terminators. In this topology, the bus acts as the backbone of the network, which joins every computer and peripherals in the network. Bus technology is mainly suited for small networks like LAN, etc. When a sender sends a message, all other computers can hear it, but only the receiver accepts it(verifying the mac address attached with the data frame) and others reject it. In other words, there is only a single transmission line for all nodes. Taps are the connectors, while droplines are the cables connecting the bus with the computer. The bus is connected to various taps and droplines. Now let us learn these topologies one by one: Bus Topologyīus topology is the simplest kind of topology in which a common bus or channel is used for communication in the network. In a computer network, there are mainly six types of physical topology, they are: We'll learn about different types of physical topologies, their advantages, and disadvantages.

In this blog, we will mainly concentrate on physical topologies. A network can have one physical topology and multiple logical topologies at the same time. Network topology defines the layout, virtual shape, or structure of the network, not only physically but also logically. In other words, it is the way in which the devices communicate internally. It is bound to a network protocol and defines how data is moved throughout the network and which path it takes. Logical Topology: A logical topology describes the way, data flow from one computer to another.In other words, we can say that it is the physical layout of nodes, workstations, and cables in the network.

It is the arrangement of various elements(link, nodes, etc.), including the device location and code installation of a computer network. Physical Topology: A physical topology describes the way in which the computers or nodes are connected with each other in a computer network.In computer networks, there are mainly two types of topologies, they are: A topology mainly describes how devices are connected and interact with each other using communication links. In computer networks, a topology is used to explain how a network is physically connected and the logical flow of information in the network. Topology is derived from two Greek words topo and logy, where topo means 'place' and logy means 'study'.
