WiFi is a technology that uses radio waves to provide network connectivity. A WiFi connection is established using a wireless adapter to create hotspots - areas in the vicinity of a wireless router that are connected to the network and allow users to access internet services. Once configured, WiFi provides wireless connectivity to your devices by emitting frequencies between 2.4GHz - 5GHz, based on the amount of data on the network.
The term hotspot is used to define an area where WiFi access is available. It can either be through a closed wireless network at home or in public places such as restaurants or airports.
In order to access hotspots, your computer should include a wireless adapter. If you are using an advanced laptop model, it will probably include a built-in wireless transmitter already. If it doesn't, you can purchase a wireless adapter that will plug into the PCI slot or USB port. Once installed, your system should automatically detect the WiFi hotspots and request connection. If not, you should use a software to handle this task for you.
