A wired connection refers to a method of connecting devices using physical cables, such as Ethernet cables. This type of connection is commonly used in homes and offices to link computers, printers, and routers, providing a stable and reliable network. Wired connections typically offer faster speeds and lower latency compared to wireless options, making them ideal for activities like gaming and video streaming. In addition to Ethernet, other types of wired connections include USB for peripheral devices and HDMI for audio-visual equipment. These connections ensure that data is transmitted directly between devices, reducing interference and improving overall performance.
