Wired connections refer to the physical links between devices using cables, allowing them to communicate and share data. Common types of wired connections include Ethernet, USB, and HDMI. These connections provide stable and reliable communication, often resulting in faster data transfer speeds compared to wireless options. In a wired network, devices like computers, printers, and routers are connected through cables, creating a local area network (LAN). This setup is often used in homes and offices for its security and reduced interference, making it ideal for activities that require consistent connectivity, such as gaming or video conferencing.
