There are also different types of network connections used to connect devices to each other. Topologies are the arrangements of these network connections and elements (links, nodes, etc.) The collapsed ring topology is the most common topology due to the Ethernet supporting the internet, local area networks, and wide area networks. The most common topologies are described below.
A central node connects a cable to each computer in the network in a star topology. Each computer in the network has an independent connection to the center of the network, and if one connection breaks, it won’t affect the rest of the network. However, one downside is that many cables are required to form this kind of network.
A ring topology is like a bus topology because it uses a single cable with the end nodes connected to each other so the signal can circle through the network to find its recipient. The signal will try several times to find its destination even when the network node is not working properly.
