Cables and topologies form the backbone of every network. In this episode, we break down the essential physical media—coaxial, twisted pair, and fiber optic—and explain where and why each is used. You’ll also learn about connectors like RJ-45, LC, SC, and ST, plus fire ratings such as plenum, riser, and PVC that keep networks both functional and safe.From there, we explore the topologies that shape how networks are organized: bus, ring, star, mesh, and hybrids. You’ll discover how these layouts affect performance, fault tolerance, and troubleshooting in real-world scenarios.By the end of this episode, you’ll understand not just the “what” but the “why” behind cabling and topology choices—knowledge that’s vital for both the exam and your IT career.
