A standard network topology refers to the physical or logical arrangement of different elements (nodes, links, etc.) in a network. Common types include star, ring, bus, and mesh topologies, each with its own advantages and disadvantages. The choice of topology affects the network's performance, scalability, and fault tolerance. Understanding these structures is essential for designing efficient and reliable networks.
Local area networks (LANs) commonly use several topologies, with the most prevalent being star, bus, and ring topologies. The star topology connects all devices to a central hub or switch, facilitating easier management and fault isolation. The bus topology involves a single central cable to which all network devices are connected, while the ring topology connects devices in a circular format, where data travels in one direction. Each topology has its advantages and disadvantages, influencing its selection based on network size and requirements.

The Public Switched Telephone Network (PSTN) is primarily based on three topologies: the star topology, the ring topology, and the mesh topology. In a star topology, all devices connect to a central hub or switch, facilitating straightforward communication. The ring topology connects devices in a circular fashion, allowing data to pass in one direction, while the mesh topology offers multiple pathways between nodes for redundancy and reliability. Each topology serves distinct purposes in the overall structure of the PSTN.
Four collision domains are present Two broadcast domains are present.
Bus topology is not a broadcast type
none
Advantages include: Its easy to set up, handle, and implement, It is best-suited for small networks and its less costly. There 3 types of topology which are; ring, bus and star topology.

"Topology"? If you mean Technology, the answer is: Increased fuel efficiency and lower hydrocarbon emmisions
you can cut logs out of it
No, because there is a hub between star topology and every station connect to that central hub. hub cause broadcast and congession since packet loss is more likely to occur. I suggest that mesh topology is more faster as there is a dedicated link to each node.
To determine the number of collision and broadcast domains in a network topology, one must analyze the devices involved. Each switch creates separate collision domains for each connected device, while a router or Layer 3 switch creates separate broadcast domains. Without a specific topology diagram or description, it's impossible to provide an exact count; however, generally, each switch adds collision domains, and each VLAN or router adds a broadcast domain.
