Which technology would you use to replace wired connectivity for mobile devices?

• A. Ethernet
• B. Bluetooth
• C. Wireless Fidelity (Wi-Fi)
• D. NFC

Answer: (C)

To replace wired connectivity on mobile devices, you need a wireless networking option that provides solid speeds, good coverage, and easy access to local networks and the internet. Wi-Fi fits this role because it uses wireless access points to connect devices to a home or office network without cables, offering fast data rates and the ability to roam between different access points as you move around. This makes internet access and network services seamless on phones, tablets, and laptops. Ethernet is a wired standard, so it isn’t practical for mobile devices that you carry around. Bluetooth works well for short-range connections to peripherals or small data transfers but isn’t designed for reliable broad internet access or network connectivity. NFC is intended for very close-range data exchanges and tasks like contactless payments, not for general networking. Because of its combination of range, speed, and network access, Wi-Fi is the best choice to replace wired connectivity for mobile devices.
