The wireless networking technology that allows portable devices, computers, and other equipment to connect to the internet is known as Wi-Fi. Remember the days when a device’s link to the internet was made through a tangle of local network cables.  Wi-Fi router works similarly to these connectors, but it works wirelessly and much more easily.

If there are too many Wi-Fi router in the area, your connection may be disrupted.

Since its introduction in the mid of twentieth century, several upgraded versions of Wi-Fi have appeared.

This is why, in today’s world, we can hold video phone conversations over Wi-Fi.
