What is a primary feature of Wired data connections?

A primary feature of wired data connections is that they utilize physical cabling to transmit data between devices. This cabling can include various types such as Ethernet cables, coaxial cables, or fiber optic cables. This direct physical connection tends to offer advantages such as greater stability, higher data transfer speeds, and typically lower latency compared to wireless communications. Additionally, wired connections are generally less susceptible to interference from environmental factors, enhancing reliability in data transmission.

In contrast, connections that rely on radio signals or wireless communication are not categorized as wired, as they utilize airwaves rather than physical cables for data transmission. Meanwhile, the claim that wired connections primarily transmit data over the internet is misleading, as wired connections can equally function within a local area network (LAN) and do not inherently restrict themselves to internet connectivity.
