What is WiFi, Types, How does WiFi Work, Advantages and Disadvantages?. In the previous articles, we have given How does RAM work and How does VPN work? Today we are discussing wi-fi meaning, how wifi works, types of wi-fi, advantages, and disadvantages.WiFi stands for Wireless Fidelity and is the same thing as saying WLAN which stands for “Wireless Local Area Network.” Wi-Fi is a popular wireless networking technology. Wi-Fi stands for “wireless fidelity”. The Wi-Fi was invented by NCR corporation/AT&T in Netherlands in 1991. By using this technology we can exchange the information between two or more devices. Wi-Fi has been developed for mobile computing devices, such has laptops, but it is now extensively using for mobile applications and consumer electronics like televisions, DVD players, and digital cameras. There should be two possibilities in communicating with the Wi-Fi connection that may be through
There should be two possibilities in communicating with the Wi-Fi connection that may be an access point to the client connection or client to client connection. Wi-Fi is one type of wireless technology. It is commonly called as wireless LAN (local area network). Wi-Fi allows local area networks to operate without cable and wiring.

How Does Wi-Fi Work?
WiFi works off of the same principal as other wireless devices – it uses radio frequencies to send signals between devices. The radio frequencies are completely different say from walkie-talkies, car radios, cell phones, and weather radios.
Wi-Fi currently carries more than 60% of the world’s Internet traffic. Interestingly enough, this great achievement is basically done with radio waves, though it’s a little more complicated than your car stereo. Unlike the FM receiver in your car, Wi-Fi is essentially two radios communicating back and forth that use lower power and broadcast over a much shorter distance. These two radios let web users download data from the Internet as well as upload information — even just submitting addresses via your browser counts in this two-way communication.
Wi-Fi also has a number of security features. To access the network, users must have a password for WPA2, also known as Wi-Fi Protected Access (the 2 represents the fact that this feature is in its second generation). This is where you put in your password to get onto the Wi-Fi network. There’s another security feature called Advanced Encryption Standard (better known as AES) that was developed by the U.S. government to keep data safe as it transmits from one device to the other.
