What does a basic computer network topology describe, and which two types are common?

• A. The data encryption standards used by the network
• B. The color of cables used in the network
• C. The arrangement of network nodes; common types include star and bus
• D. The location of network devices

Answer: (C)

The arrangement of network devices and how they are connected to each other is what a basic network topology describes. It shows how computers, printers, routers, and other nodes share a communication path. Two common topologies are star and bus. In a star, every device links to a central hub or switch, making it easy to add devices and manage traffic, though the central device is a single point of failure. In a bus, all devices share a single communication line, which is simple and cost-effective for small networks but can suffer if the main cable has a problem or becomes congested. This focus on layout and interconnections explains why topology is about structure, not things like encryption, cable color, or where devices sit physically.
