ccna 200 301 syllabus definition and example of allusion.Two or more physical or logical network topologies are used together in the same network.Figure 1.15 depicts a simple hybrid network topology: a LAN switchor hub is located at the center of the star topology and connects multiple physical star topology, logical bus topologyhosts.Figure 1.15 Simple Hybrid NetworkReal-world scenarioA cable is just a cable, right?Wrong! No matter what type of network you build, you need to think about the quality requirements of your network from the beginning and gradually go deeper from there.Imagine you're shopping for cables for a home theater system in your new home at an electronics store. You've spent a lot of time and money shopping for the necessary equipment. In fact, your mind has probably changed: Why would you want to equip such a great set of equipment with cables of such unequal quality here? You're making a much wiser choice. You know that choosing the right cables will bring out the best sound and picture quality of this set, while also providing protection for the equipment.You face the same problem when choosing physical media for a particular network, such as a new client/server network one you definitely don't want to be frugal in this area. Because these cables form the backbone of the network, you definitely don't want to dig them out one by one after everything is installed. Instead of making up for it after the fact, you should spend time and money carefully selecting the right cables before implementation; the cost of making up for it after the fact is even more massive. A network going down can be costly (pun intended) to a company. Another reason to choose your network's physical media carefully is that these cables will last 5-10 years. This means two things: the cables better be of very high quality; and the network design better be scalable, because the network will grow and change in size over time.
