Which topology is described as a single cable that connects all devices, with two endpoints, and is also called linear topology?

• A. Physical Topologies
• B. Physical Topologies (Bus)
• C. Patch Panel
• D. Patent

Answer: (B)

The concept here is the bus topology: a single central cable runs in a straight line and every device connects to that same line. Because the cable has two endpoints, you place terminators at each end to absorb signals and prevent reflections. Data travels along the line and all devices share the same medium, which is why transmissions can collide if more than one device talks at once; older Ethernet used CSMA/CD to manage this. As more devices are added, performance and fault isolation suffer, making it less scalable and less common today. The other terms are broader or unrelated: “Physical Topologies” is a general category, a patch panel is just a hardware organizing device, and “patent” doesn’t pertain to network topologies.
