Wi­Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high­speed Internet and network connections. A common misconception is that the term Wi­Fi is short for "wireless fidelity," however this is not the case. Wi­Fi is simply a trademarked phrase that means IEEE 802.11x. Point 2 Point is a protocol for communication between two computers using a serial interface, typically a personal computer connected by phone line to a server. For example, your Internet server provider may provide you with a PPP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. PPP uses the Internet protocol (IP) (and is designed to handle others). It is sometimes considered a member of the TCP/IP suite of protocols. Relative to the Open Systems Interconnection (OSI) reference model, PPP provides layer 2 (data­link layer) service. Essentially, it packages your computer's TCP/IP packets and forwards them to the server where they can actually be put on the Internet.
