Network Topology:
When we connect computer with network we have to use logical manner. The layout or pattern of interconnections between different computers in a network is called network topology. Network topology is referred to as network architecture. Every device in network are referred to as nodes.The following are different types of network topologies.
- Point To Point
- Bus
- Star
- Ring
- Mesh
- Tree And Hybrid
- Point to Point Topology:
Point to point topology is the simplest topology among the other network topologies. This topology network consists of a direct link between two computers only. This way of connection is faster and more reliable then other types of connections due to direct connection. Keep in mind only two computer were used in
this topology no more.
- BUS Topology:
Bus topology is a type of network and every computer device is connected to a single cable in series, also known as linear bus topology. In Bus topology all nodes are directly connected via cable. Cable acts as a backbone for the network connection in bus topology. One computer among all act as a server and other are act as client. It is not necessary that only one server is used in bus topology, server may be one or more then one depending upon the requirement of user. Bus topology is easy to connect a computer or peripheral device, cable requirements are relatively small that result in lower cost. But if cable break the entire network failed because only single wire is used in bus topology. Bus topology is difficult to troubleshoot. Hence Bus topology is not used for large networks, connection.
- Star:
In star topology every computer is connected to a central hub (Server of Network) using a point to point connection, every client or nodes are connected to central hub, keep in mind every clients or nodes are not connected with one another. Central hub or server is use to manage whole network, or it may be simple device that is used as a connections between different computers over the network possible. This topology is popular and low costly. It is easy to add new nodes to central hub. The whole network is failed if central hub is failed or damage, if any one connections between a computer and the central hub fails, the other connections remain intact and never failed only specific interact failed. Star topology requires more cable as compared to bus topology, therefore it is more expensive.
- Ring:
In Ring topology computers/devices are connected to a closed loop cable i.e connected in a circle. Ring topology have no terminating ends hence if one system failed the entire network never failed. In Ring topology data is sent by using a token to prefer which side is used due to two way of sending data, token decide which side is used to transfer data. If the token isn’t carrying any data, in this case computer waiting to transfer data seizes it, attaches the data and the electronic address to token and transfer it on desire place or destination. When the token is received by the desire computer it strips the data and the token transfer on it. Hence we called it’s named a token ring network
- Mesh:
In Mesh topology all nodes cooperate to distribute data among all other devices. Mesh is a point t point connection to other nodes or client. All nodes/client are connected to each other. Mesh has n(n-1)/2 physical channels to link n devices. Mesh is complex topology and even any one system failed the entire network never failed. It required more cables then Star and Ring topology and this topology is costly as compared to Star and Ring topology.
- Tree And Hybrid
In Tree topology are connected elements in different arrangement as branches of a tree. This type of topology is too complex and require more cable as compared to other topology. A Tree network is a Hybrid network topology in which star topology are interconnected via Bus topology.
