The correct answer is: A. Wi-Fi
Wi-Fi is a wireless networking technology that allows devices to connect to the internet or to each other without the need for cables. It is a popular choice for public internet access at hotspots such as restaurants, coffee shops, and airports.
Wi-Fi works by using radio waves to transmit data between devices. The radio waves are sent from a wireless access point (AP), which is a device that is connected to the internet. The AP then sends the data to the devices that are connected to it.
Wi-Fi is a convenient and affordable way to connect to the internet. It is also a secure way to connect, as data is encrypted when it is transmitted.
Here is a brief explanation of each option:
- WiMax is a wireless broadband technology that can be used to provide high-speed internet access over long distances. It is not typically used for public internet access at hotspots.
- DFL is a digital subscriber line (DSL) technology that can be used to provide high-speed internet access over copper telephone lines. It is not typically used for public internet access at hotspots.
- BPL is a broadband over power line (BPL) technology that can be used to provide high-speed internet access over power lines. It is not typically used for public internet access at hotspots.
