How Wi-Fi works for a computer system?

Wi-Fi is a term shortened for “wireless fidelity”. In simple terms, it can be said that a computer would be able to connect to the internet without any cables or wires.

In its operation, Wi-Fi is similar to the cell phone. It receives and sends signals along with data in the manner similar to mobile networks.

In case of Wi-Fi, first the computer or the Bluetooth device transmits radio signals to the wireless routers. The wireless router can either be Wireless Local Area Network or Wireless Access Point. The received signals are then sent to the internet via a cable modem, after which you can easily connect yourself to the internet.

Broadband Wi-Fi also works in the same manner. The only difference is that the bandwidth for the signal transmission has increased, which eventually has provided the wireless world with a new dimension of internet surfing.
