Guide on Physical Topology: CompTIA Network+ Perspective

Physical Topology refers to the actual layout of the computer networks' physical connections and devices. It outlines how different devices and cables are interconnected, including routers, switches, hubs, and modems.

From the CompTIA Network+ perspective, understanding Physical Topology is crucial because it allows network professionals to visualize and manage the placement and connections of different network components.

Physical Topologies work by interconnecting different network devices using various topological structures, such as Bus, Ring, Star, Mesh, and Tree. Each has its unique features, benefits, and limitations.

Exam Tips:
1. Understand the core attributes of each topology. For example, a Star topology has a central connection point, usually a hub or switch.
2. Be able to distinguish between the different topologies based on their diagrams.
3. Know the advantages and drawbacks of each topology. Such as, Mesh topology provides high redundancy but requires more cabling.
4. CompTIA Network+ likes to apply the facts to real-world scenarios, so be prepared to answer questions like 'Which topology would be best for a particular scenario and why?'
