What is the most commonly used wired networking method for desktop PCs to connect to a local area network?

1. Token Ring

2. Ethernet

3. Wi-Fi

4. Fiber Optic

The correct answer is: Ethernet

The most commonly used wired networking method for desktop PCs to connect to a local area network is Ethernet. This technology has become the standard for local area networking due to its simplicity, speed, and cost-effectiveness. Ethernet supports a variety of data rates and is widely compatible with various networking equipment, making it highly accessible for both home and business environments. Ethernet uses copper or fiber optic cables to transmit data packets between devices within the same network. It operates on a bus or star topology, allowing for easy setups with switches or routers to manage traffic efficiently. The ubiquity of Ethernet technology, along with its ability to provide reliable connections with deterministic performance under typical networking conditions, contributes to its popularity. Other options listed do not match the common usage for wired networks. Token Ring, while historically significant, has largely fallen out of favor and is rarely used today. Wi-Fi represents a wireless networking method, which does not pertain to wired connections. Fiber optic is a medium that can be used within Ethernet networks but is not as commonly utilized for connecting standard desktop PCs in most LAN setups due to increased costs and complexity.
