If you have a computer network in your home or office, there are several different ways to connect the computers on your network together. Most people are familiar with wired networks where physical wires are run under the street or across street poles, through building structures, and from the wall to your PC. Wi-Fi (wireless fidelity) is the wireless way to handle networking. It is also known as 802.11 networking and wireless networking. The big advantage of Wi-Fi is its simplicity. You can connect computers anywhere in your home or office without the need for wires.
Wi-Fi is basically a wireless networking technology that’s used in homes and offices to allow people that have devices with Wi-Fi receivers to transmit data over a network. As far as mobile devices are concerned, what they’re doing is using the Wi-Fi to complete telephone calls, by transmitting the same packets that would be sent over a larger network inside the smaller Wi-Fi network and that can be faster and more efficient.
