Wifi is the other name for wireless internet or wireless network, this name is mostly used by none technical users who just knows how to access internet wirelessly, wifi extender  they know pretty much nothing beyond that. Wifi is basically short form for wireless fidelity. However many advance users are not well aware of this terminology either, it is, more known with a name of Wifi. Wifi term is written in many ways which are, Wifi, Wifi, WIFI, Wi-Fi fiwi etc.

Wi-Fi was introduced by Wi-Fi alliance in 1985 it was the time when it was not used as commercially but were just set to certain organizations for testing purposes. Wi-Fi Alliance is pioneer in developing Wifi technology and all the hardware associated with Wifi is mostly certified by Wifi Alliance compliance. Wifi later developed properly and than eventually lunched for public use in USA in 90's, gradually wifi become standards for most of the computer communications in countless organizations around the world

Wifi uses all the networks referring to any type of 802. 11 network standards which is set by IEEE. IEEE is short form of Institute of electric and electronic engineering. There are lots of enhancements made in standards of 802. 11 and 802. 11a, 802. 11b and other dual networks. The latest standard of 802. 11 family is 802. 11y. Other known standards are 802. 16, these are the standards for upcoming technology known to be WiMax. There is one more known set of standards for Ethernet it is known to be IEEE 802. 3.

Growth of Wifi networks is still on going world wide this huge growth raises security issues. Wifi is the most widely used network world wide and many organizations transfer their sensitive data using Wireless networks. Increased use of Wireless network increases potentially risks of the security of the users or organization. Wireless network carries data of every type, that can be normal data in bits of information or it can encrypted or even highly sensitive. Wifi security mechanism insures the certain level of data integrity and confidentiality just as wired network provides. However if proper security measures are not adopted properly intruders can attack the network and can cause major damage to not only network but privacy of users also.

There was a time when cables were used to network many computers together. Hardware like routers, hubs, switches etc were required for communication between computers, but Wifi brought high tech change in communication of computers by providing wireless connectivity features. It just keeps things very simple without much hassle and networks can be made far more easily. No wires are required. Wireless network keeps environment very neat and clean. There are many other features of Wireless LANs for example high speed connectivity. Wifi provides high speed connectivity and faster communication where cables are not feasible to install for example in remote areas. The list of the Wifi features is long some other major features included Site survey, enterprise grade equipment, Scalable systems, VPN Compatibility, flexible authentication methods, Guest satisfaction, End user mobility and easy access through Hotspots.
