Cords are flexible, elongated materials used to connect or secure objects. They can be made from various materials, including cotton, nylon, or rubber, and come in different thicknesses and lengths. Common uses for cords include tying items together, hanging objects, or providing electrical connections. In the context of electronics, cords often refer to power cords and data cables. Power cords supply electricity to devices, while data cables transfer information between devices, such as USB cables for computers and HDMI cables for televisions. Both types of cords are essential for the functionality of many modern devices.
