As of today, practically all wired keyboards communicate with computers over the USB port. PS/2 is a serial port interface that may be used by older computers to connect to the computer. Bluetooth, RF (radio frequency) and infrared (IR) are all options for connecting with your keyboard if it is wireless or cordless (infrared).

The following are the steps to follow in order to connect each of these different types of computer keyboards.

Connecting a USB keyboard

Connect the USB keyboard to your computer by plugging it into one of the USB ports on the back or front of the computer. If you’re utilising a USB hub, it will be able to communicate with the hub as well. However, if at all possible, we recommend that you connect directly to the back of the computer.

If you have a laptop computer, you may also attach an external keyboard to one of the USB ports on the computer. The use of a USB hub would be necessary if there are no USB ports available.

As soon as the keyboard is attached, it should be recognised and installed by the operating system. If your keyboard has any special capabilities, you’ll need to make sure the keyboard software and drivers are installed. Basic mouse settings are available in all operating systems, and they allow you to set up and customise the most basic mouse settings.

Can my laptop work with two keyboards?

Yes. When you attach an external USB keyboard to a laptop, it serves as a second keyboard, allowing you to use both keyboards at the same time without switching between them.

What if my keyboard has two USB cables?

Some more advanced USB keyboards (for example, a gaming USB keyboard) come with two USB cords to accommodate multiple users. One of these wires is for the keyboard, while the other is for the USB port(s) on the keyboard, which can be used to connect additional USB devices to the computer. If you only require the keyboard, only one of these wires will be required to be attached.

Connecting a wireless keyboard

All wireless keyboards have a receiver that is connected to the computer (often via a USB connection), and the keyboard communicates with the receiver via wireless communication. Connect this receiver to the rear or front of your computer, depending on your preference. Once connected, check to see if your wireless keyboard has batteries or is fully charged and operational before proceeding.

These keyboards may be turned on by just flipping them over and looking at the back of the keyboard. A switch that can be moved from the on position to the off position should be located towards the bottom or top of the keyboard.

How to enable the keyboard

Wireless keyboards are equipped with a power button located at the bottom of the keyboard, which allows them to be turned on and off as needed. If the keyboard is not identified, check to see that the power switch is in the “on” position on the wall. Also, if your wireless keyboard is powered by replaceable batteries, be certain that the keyboard is equipped with known good batteries.

Connecting a PS/2 keyboard

The PS/2 port on the rear of the computer should be used to connect the keyboard.
When you look at the rear of the computer, you’ll note that it has two PS/2 ports that are adjacent to one another. Please double-check that the keyboard is connected to the purple connection, as indicated in the illustration below. If the PS/2 ports are not color-coded, the keyboard connection will be the one that is closest to the left edge of the computer screen (when looking at it from the back). When using vertical connectors, such as the ones shown in the illustration below, the keyboard connection can be made through either port, depending on the case and motherboard. Look for a small keyboard sign next to the port to determine which one is intended for the keyboard and which one is not.

Do all computers have a PS/2 port?

Because USB ports have replaced the older PS/2 port on newer desktop and laptop computers, the former is no longer available. If you have an outdated PS/2 keyboard or other PS/2 device, you can upgrade to a PS/2 to USB adaptor (connection), such as the one shown in the illustration. Through the use of this adapter, an older keyboard can communicate with newer computers by connecting to one of the USB ports and the PS/2 socket on the computer.

Can I plug any keyboard into my computer?

Keyboards are fairly general in that they may be used with any desktop, laptop, or portable computer (PC or Mac) that has the necessary keyboard port to connect to. When you plug a keyboard into a computer, the computer should begin to function immediately. When using some more advanced keyboards that have specific keys or features, it is possible that those features will not function until the programme has been installed. Even if the software is incompatible with your computer or operating system, you can continue to use the fundamental keyboard functions without having to worry about missing out on the special capabilities. It is necessary to troubleshoot the keyboard using one of the links provided below if nothing on it functions properly.
