Check whether it is Bluetooth or 2.4 GHz wireless
Bluetooth devices connect without a receiver or wire. It's also utilised on cellphones and tablets, therefore it's suggested for non-computer users. You can buy a receiver to utilise it with non-Bluetooth devices.
2.4GHz wireless uses radio waves to link wireless LAN, etc. Dedicated receivers allow wireless connectivity on PCs without Bluetooth. Cheaper than Bluetooth and with less communication delay.
