- - - - A ring network is a network topology in which each node connects to exactly two other nodes, forming a single continuous pathway for signals through each node - a ring.
        
        Advantages
        
        Very orderly network where every device has access to the token and the opportunity to transmit
        
        Performs better than a bus topology under heavy network load
        
        Does not require a central node to manage the connectivity between the computers
        
        Point to point line configuration makes it easy to identify and isolate faults.
        
        Reconfiguration for line faults of bidirectional rings can be very fast, as switching happens at a high level, and thus the traffic does not require individual rerouting.
        
        Disadvantages
        
        One malfunctioning workstation can create problems for the entire network. This can be solved by using a dual ring or a switch that closes off the break.
        
        Moving, adding and changing the devices can affect the network
        
        Communication delay is directly proportional to number of nodes in the network
        
        Bandwidth is shared on all links between devices
        
        More difficult to configure than a Star networks
    - - In a star network, every host is connected to a central hub.
        
        Advantages
        
        If one node or its connection breaks, it doesn’t affect the other computers nor their connections
        
        Devices can be added or removed without disturbing the network
        
        They work well under heavy loading
        
        It is possible to create very large network
    - - A bus network is a network topology in which nodes are directly connected to a common linear (or branched) half-duplex link called a bus.
        
        Disadvantages
        
        Entire network shuts down if there is a break in the main cable or one of the T connectors break
        
        Large amount of packet collisions on the network, which results in high amounts of packet loss
        
        Slow with many nodes in the network
        
        It is difficult to isolate any faults on the Network
        
        Advantages
        
        Very easy to connect a computer or peripheral to a linear bus.
        
        Requires less cable length than a star topology resulting in lower costs
        
        The linear architecture is very simple and reliable
        
        It works well for small networks
        
        It is easy to extend by joining cable with connector or repeater
        
        If one node fails, it will not affect the whole network
    - - A mesh network is a fully connected mesh network is where each node is connected to every other node in the network.
