The importance of a keyboard:
- Input devices are keyboards. Any peripheral or computer gear that controls signals to your computer is referred to as an input device. Input devices or peripherals include keyboards, scanners, and even gaming controllers.
- This is the most popular type of input device, consisting of a series of buttons or keys. It's similar to a typewriter. A keyboard has a matrix of switches and a keyboard controller on the inside. When you press a key, it presses its switch, and when you release it, it releases its switch. The keyboard controller generates a scan code by pressing and releasing switches.
- Keyboards come in a variety of sizes and styles. Gone are the days when you could just use the keyboard that came with your computer. Today's keyboards include a variety of functions for home and workplace use, including built-in dual speakers for stereo sound, media consoles for playing and navigating through your music, and internet browser controls for a better online browsing experience.
