Key Takeaway:
Whether through Wi-Fi tethering (the mobile device becomes a wireless hotspot) or USB tethering (the mobile device acting as a sort of external wireless card), tethering is a cool feature allowed by some mobile devices and their carriers. There is usually an extra cost associated with the service. Pairing is the term referred to in Bluetooth connections, and Internet Pass through is the reverse of tethering, allowing a user to access the Internet through the PC’s Internet connection.
