What technology allows multiple devices to connect to a network wirelessly?

• A. Ethernet
• B. Wi-Fi
• C. Bluetooth
• D. Fiber Optics

Answer: (B)

Wi-Fi is a technology that enables multiple devices to connect to a network wirelessly, utilizing radio waves to transmit data. This capability allows devices such as laptops, smartphones, tablets, and smart appliances to access the internet and communicate with each other without the need for physical cables. Wi-Fi operates based on various standards defined by the IEEE 802.11 family, which outlines protocols for wireless communications, providing flexibility and ease of connection for numerous devices simultaneously. In contrast, Ethernet refers to a wired networking technology that relies on physical cables to connect devices, making it unsuitable for wireless connectivity. Bluetooth is designed for short-range, low-power connections between devices, primarily for peripheral devices like keyboards, mice, or audio headsets, rather than for broader network access. Fiber optics is a high-speed data transmission technology that employs light signals through fiber cables, again requiring a physical connection rather than a wireless one. Overall, Wi-Fi stands out as the primary technology for facilitating wireless networking among multiple devices.
