Tethering

Tethering is like sharing your internet connection with another device. When you tether your device, it takes the internet connection from your phone, tablet, or laptop and sends it to another device, so that it can also use the internet. For example, if you have a phone with a strong internet connection, you can tether it to your laptop and then use the web on your laptop too.
