Wi-Fi is a LAN (local area network) that used to transmit and receive data over distances of few hundred feet with the help of high frequency radio signals. Simply a Wi-Fi is a Wireless LAN network. This allows an electronic device like computer, Mobiles, Digital devices to transmit the data wirelessly over a network like internet to the Wireless Network Point.

Wi-Fi Alliance is the Organization that owns Wi-Fi. Wi-Fi was commercially available from 2000. Before that it is known as IEEE 802.11b Direct Sequence. The Interbrand Corporation named and created the Wi-Fi logo. Simply Wi-Fi is wireless Fidelity. A Wi-Fi-enabled device can be able to connect to the Internet within certain range of a wireless network. The device has to be configured with the proper permission.

Benefits and Security:  Wi-Fi also connects places that normally don't have network access, such as kitchens and gardens without any need for the cables. In an earlier stage the Wi-Fi is less secure than wired connections because an intruder can easily hack the network. Unencrypted internet access can easily be detected by intruders. So Wi-Fi has adopted various encryption technologies like WPA, WPA2.

Wi-Fi Hotspot: Wi-Fi hotspot offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots may be found in coffee shops and various other public establishments in many developed urban areas throughout the world. A Wi-Fi hotspot is a wireless access point that provides Internet access to network devices in public locations such as downtown centers, cafes, airports and hotels. Businesses and schools are increasingly using Wi-Fi hotspots for their internal networks.

Wi-Fi Direct:  Wi-Fi Direct enables devices to connect and access network without need of Wi-Fi network. Only one of the Wi-Fi devices needs to be accessed with Wi-Fi Direct to establish connection. Wi-Fi Direct device will signal to other devices in the area that can make a connection.  The device can receive an invitation to connect or send a request to connect to another Wi-Fi Direct device.  When two or more Wi-Fi Direct-certified devices connect directly, they have formed a Wi-Fi Direct Group, using Wi-Fi Protected Setup™ and the latest Wi-Fi security.
