MEMES on Instagram: "😂 A keyboard is a device used to type letters, numbers, symbols, and commands into a computer, phone, tablet, or other electronic system. It works by sending a signal every time you press a key. That signal tells the device what character or action to display, like writing a word, deleting text, or controlling software. Most keyboards follow a layout called QWERTY, named after the first six letters on the top row."
