PROBLEM TO BE SOLVED: To provide a keyboard that can conveniently check a network connection state, and an electronic device having the same.SOLUTION: A keyboard 23 includes a keyboard main body, a keyboard port 233 provided in the keyboard main body, a signal processing module 237 and a connection state indicator 239 electrically connected to the signal processing module 237. The keyboard main body is connected to a host 21 with a microchip 211 through the keyboard port. The host outputs a corresponding control signal through the microchip, the control signal is transmitted to the signal processing module through the keyboard port, and the signal processing module performs processing on the received control signal and outputs a corresponding driving signal, to turn on or off the connection state indicator, for indicating a network connection state between the microchip and a local area network. |
