A button is a small, typically round object used to fasten clothing or accessories. It is usually made from materials like plastic, metal, or wood and features a hole or shank on its back for sewing onto fabric. Buttons come in various sizes, colors, and designs, allowing for both functional and decorative purposes. In addition to clothing, buttons are also found on electronic devices, such as remote controls and computers. These buttons serve as controls for various functions, allowing users to interact with the device. They can be mechanical or touch-sensitive, depending on the technology used.
