Free Wi-Fi refers to wireless internet access that is provided at no cost to users. It is commonly available in public places such as cafes, libraries, airports, and parks. This service allows people to connect their devices, like smartphones and laptops, to the internet without needing a personal data plan. Many businesses offer free Wi-Fi to attract customers and enhance their experience. Users can browse the web, check emails, and use social media while enjoying their time in these locations. However, it is important to be cautious when using free Wi-Fi, as it can pose security risks if proper precautions are not taken.
