Corded
Traditionally, keyboards have had a cable that connects the keyboard to the computer using a USB port, hence a corded keyboard, and using a corded keyboard has its advantages.
Wireless
Wireless keyboards are either receiver-based or Bluetooth-based. Receiver-based keyboards connect to the computer via a nano receiver that plugs into a USB port.
Comfort
Keyboards, next to displays and mice, are the most used parts of your computer. Your hands go to it every time you sit down and it’s probably the last thing you touch.
