Wi-Fi




Wi-Fi is a wireless networking protocol. It allows devices to communicate without internet cords.

Technically it is an industry term that represents a type of wireless local area network (LAN) protocol. It's a trademark of the Wi-Fi Alliance, an international association of companies involved with wireless LAN technologies.

Wi-Fi is sometimes mistaken as an acronym for «wireless fidelity».

For a Wi-Fi is that there's a device that can transmit the wireless signal, like a router.

In a typical home, a router transmits an internet connection coming from the source outside the network , like an ISP (Internet Service Provider), and delivers that service to nearby devices that can reach the wireless signal.

Another way to use Wi-Fi is a Wi-Fi hotspot so that a phone or computer can share its wireless or wired internet connection, similar to how a router works.

It is , when it is shared ..

There are tons of places to get free Wi-Fi access, like in restaurants and hotels, but Wi-Fi isn't free.

We have the the internet at our house, we're paying a monthly a fee to keep it coming. regardless of whether or not it is used.

However, most home internet connections don't have data caps, which is why it's not a problem to download hundred of gigabytes of data each month.

A data cap (bandwidth cap) is a service provider-imposed limit on the amount of data transferred, over a given time period.

To set up Wi-Fi access, just configure a wireless device to connect to a Wi-Fi network. T Ensure that the Wi-Fi connection is enabled and then searching for a nearby network to provide the proper SSID and password to make the connection.

We can also share our internet connection with other devices to create a wireless hotspot from our router or computer.
