What are the high-level categories of networking?

• A. Wireless
• B. Wired
• C. Both Wired and Wireless
• D. None

Answer: (C)

Networking is categorized by the medium used to carry data. The two main forms are wired and wireless. Wired networks rely on physical cables such as copper Ethernet or optical fiber, and they typically offer stable, high-speed connections with predictable performance. Wireless networks use radio waves, enabling device mobility and easier access without cables, though they can face interference and variable signal quality. In most real-world setups, both are used together—wired infrastructure provides the backbone, while wireless connects devices without limits of cabling. Choosing only wireless or only wired misses this complete picture, so the option that includes both wired and wireless best fits the concept.
