Bus topology
You can find information on tree topology in networking textbooks, online resources such as websites, forums, and tutorials, and through professional courses or certifications in networking. Additionally, attending networking conferences or webinars can also provide insights into tree topology and its applications in networking.
Yes, peer to peer can be implemented in linear bus topology.
Different types of Networking topologies are 1] Bus topolgy 2] Ring topology 3] Mesh topology 4] Hibrid topology
Bus star ring mesh hybrid
hierarchical (extended) star topology
Ethernet is easily the most common topology having replaced token ring in the 90's. Simply because of it's ease of use with CAT5 cabling, cheap networking hardware and not needing any termination.
Topology refers to the physical method of wiring the devices to each other, what kind of connection devices are used, etc.
The most common topology in use today is the star topology, primarily due to its scalability and ease of management. This topology often utilizes Ethernet technology, particularly with twisted-pair cabling, which is prevalent in local area networks (LANs). The star topology allows for easy addition and removal of devices without disrupting the network, making it ideal for modern networking needs. Additionally, advancements in wireless technology have also popularized star topology in Wi-Fi networks.
