Not scalable as there is a limit of how many nodes you can connect with backbone cable. RING TOPOLOGY In ring topology each device is connected with the two devices on either side of it. There are two dedicated point to point links a device has with the devices on the either side of it. This structure forms a ring thus it is known as ring topology. If a device wants to send data to another device then it sends the data in one direction, each device in ring topology has a repeater, if the received data is intended for other device then repeater forwards this data until the intended device receives it. RING TOPOLOGY ADVANTAGES DISADVANTAGES 1. Easy to install. 1. 1. A link failure can fail the entire network as the signal will not travel forward due to failure. 2. Managing is easier as to add or remove a device from the topology only two links are required to be changed 2. Data traffic issues, since all the data is circulating in a ring. HYBRID TOPOLOGY A combination of two or more topology is known as hybrid topology. For example, a combination of star and mesh topology is known as hybrid topology. HYBRID TOPOLOGY ADVANTAGES DISADVANTAGES 1. We can choose the topology based on the requirement, for example, scalability is our concern then we can use star topology instead of bus technology. 1. Fault detection is difficult. 2. Scalable as we can further connect other computer networks with the existing networks with different topologies. 2. Installation is difficult. 3. ______
