The mouse and keyboard are two of the most important input devices. They are use to control the computer and type texts and commands.
Older laptops and some contemporary motherboards have a single port that supports both the mouse and the keyboard, sometimes using unused pins on the connector for this purpose.
Bluetooth How to Connect Mouse and Keyboard Wikipedia:
Bluetooth (abbreviated BT) is a wireless technology that allows devices such as keyboards and mice to connect without the need for wires.
In Linux, device pairing is typically driven by the graphical interaction agent of the underlying desktop environment.
For KDE, use kde-plasma/blue devil; for GNOME, use net-wireless/gnome-bluetooth or the corresponding system service.
A command-line interface is also available with the bluetoothctl utility, included in the net-wireless/bluez package.
To enable Bluetooth, open the Settings menu on your computer. This can be done either by clicking the Windows icon in the bottom-left corner of the screen or by pressing the Win key on your keyboard. Click the Devices option.
If your mouse has a Bluetooth receiver, plug it in, then turn on the mouse’s Bluetooth switch, usually located underneath the battery compartment.
Then put the mouse into Bluetooth pairing mode by pressing a button for several seconds, as detailed in the mouse’s documentation.
Once the mouse is in pairing mode, you can select it from the list of devices displayed by the graphical interface (e.g. KDE Bluetooth or kinputwizard).
Optical How to Connect Mouse and Keyboard Wikipedia:
Optical mice use a series of sensors to detect movement and supply the computer with machine-readable tracking data.
They typically come with large mousepads printed with a grid of gray and blue tracking lines for use as reference points, with the sensor array arranged at the top of the pad to provide better coverage.
They were traditionally power by a dedicated connector that shared power with the keyboard, but some early models had a pass-through connector that allow them to derive their power from the keyboard connection, obviating the need for an external power supply.
Microsoft Windows 8 and later includes a combined program for controlling mice and keyboards, called Mouse and Keyboard Center.
Wireless How to Connect Mouse and Keyboard Wikipedia:
Bluetooth devices use radio signals to communicate with one another. When you pair a keyboard and mouse with your PC, they transmit and receive signals via the same radio frequency.
Then, the signals are passing to an IC chip in your computer, which decodes them and displays them on the screen.
Most wireless keyboards and mice come with a receiver/dongle, which you can plug into an available USB port.
Once you plug in the receiver, your PC should automatically detect it and start recognizing its commands. If it doesn’t, you can use the Windows Bluetooth settings to manually connect your keyboard and mouse.
You can also use a Bluetooth keyboard and mouse on your mobile phone, but you’ll need to get a special adapter. Usually, these are small and don’t require a power source.
However, you’ll need to make sure that your keyboard/mouse has a built-in Bluetooth receiver and is in pairing mode. You can find this by looking for a button on the back of the device or checking its documentation.
