In this modern age, internet becomes an important thing in the world. Wi-Fi is a simple way to connect to the internet, to other computers and to other Wi-Fi-enabled devices (such as high-end Mobile Phones), without the need to physically connect wires between the two computers / devices. Wi-Fi really helps us in accessing the internet because it has 3 advantages.
The first is about flexibility. Wi-Fi provides LAN (Local Area Network) connection, which means that you do not need any cable to build LAN. The consequence is that you need a device called hotspot. Hotspot is the wireless access point that you have to reach within in order to make you able using Wi-Fi.
The second one is about availability. Wi-Fi technology nowadays is available for some electronic stuff. So not only a computer that can join the network but also some electronic stuff like hand phones, laptops, or IPod which are already have Wi-Fi technology can join the network . In the old wired LAN you can only use computer to join the network in order to connect with internet. But in this case, Wi-Fi is available on hand phones, so you can access the internet lively from your hand phone whenever and wherever you want to as long as you are still in hotspot area coverage. You also can play the music streamingly with your IPod whenever it is connected with the internet by using Wi-Fi.
The last is about security. In order to protect the network, Wi-Fi also has good security. There are 3 security techniques that have been developed by some designers, such as Wi-Fi Protected Access, Media Access Control Filtering, and RADIUS Authentication and Authorization.
