Which technology enables wireless internet access?

• A. Ethernet
• B. Wi-Fi (Wireless Fidelity)
• C. Bluetooth
• D. DSL (Digital Subscriber Line)

Answer: (B)

Wi-Fi, or Wireless Fidelity, is a technology that allows electronic devices to connect to a wireless local area network (WLAN), enabling internet access without the need for physical cables. It uses radio waves to transmit data, making it possible for devices like laptops, smartphones, tablets, and smart home devices to connect to the internet from various distances without direct connection to a router or access point. Wi-Fi operates on specific frequency bands, typically 2.4 GHz and 5 GHz, allowing multiple devices to communicate simultaneously while providing relatively high data transfer rates. Its ability to connect multiple devices and its widespread availability in public spaces, homes, and businesses make it a popular choice for wireless internet access. Ethernet, on the other hand, is a wired networking technology that uses cables to connect devices, so it does not enable wireless access. Bluetooth is designed for short-range communication between devices rather than internet access, and while DSL provides internet access, it does so via a wired connection over telephone lines. Thus, Wi-Fi is the correct choice for enabling wireless internet connectivity.
