What is built in wifi?

Answer 1

When your device is connected to a wireless network, its wireless adapter will encode information into a radio signal and then transmit it using the wireless antenna that is normally built into your device. The WiFi router for the network then receives this information, decodes it, and sends to the internet through a wired, high-speed connection.

that is when your computer/electronic device is able to connect to the internet without any wires/cables. But you need to be in a place that has a wireless internet router i.e., home, motel, library, coffee shop, airport. Many times when you try to connect to the internet, you will be prompted with the wifi's in the immediate area and when you choose one, more often than not, you will be prompted to enter a password to connect to the wifi. If you have the password, then you can connect and stay connected as long as you are in range. The range varies from model to model.
