Wi-Fi defines itself as Wireless fidelity. Wi-Fi is a range of wireless network connected to the internet. The coverage of one or more hotspots (interconnected access points) can commonly comprise an area. It is installed in many personal computers, laptops, smartphones, mp3 players and printers which provide the users to have an access to the internet.
It is a wireless networking technology which uses radio waves to supply wireless high speed network and internet connections. It is owned by an organization named Wi-Fi Alliance.
It works anywhere in the world. It allows the operation of LANs (local area network) without physical wires for the devices of the users. The sender and receiver only use radio frequency technology.
Wi-Fi networks can be classified as open and closed. It is open when anyone can use it and it is closed when you needed a password. Most of the time, you can find a Wi-Fi connection in campus, malls, restaurants and other places that are often visited by people. Most of those areas have a pass code before you can enjoy the use of their Wi-Fi. And if it's not protected, it can be susceptible to access by unauthorized users to use the access for free internet connection. And it will increase the possibility of slowing down the speed of the connection because of the unauthorized users.
It is amazing to know that wherever you go, for as long as it is Wi-Fi wide, you can connect and browse the internet.
Why go to an internet cafe to be connected to the internet when internet connection itself comes to you. Technically speaking, Wi-Fi is one of the innovations you should be proud of.
