A Wi-Fi hotspot is a physical location where people can access the internet wirelessly using Wi-Fi technology. These hotspots can be found in various places, such as cafes, libraries, airports, and public parks. They allow users to connect their devices, like smartphones and laptops, to the internet without needing a wired connection. Hotspots can be created using a router connected to a broadband internet service or through mobile devices that share their cellular data. Many public hotspots are free to use, while some may require a password or payment. Users should be cautious when connecting to public hotspots due to potential security risks.
