A doorknob is used to operate a door, allowing it to be opened or closed. Users turn the knob to disengage the latch mechanism, which then permits the door to move freely. Doorknobs can also serve as a decorative element in addition to their functional purpose. They are typically mounted on the door's surface and can be made from various materials like metal, plastic, or wood.
