Which physical device can be used to improve Wi-Fi signal strength?

• A. A wireless range extender
• B. A network switch
• C. A modem
• D. A router

Answer: (A)

A wireless range extender is specifically designed to improve Wi-Fi signal strength by amplifying the existing wireless signal and extending its coverage. This device works by receiving the signal from the router and then rebroadcasting it to areas where the Wi-Fi signal is weak or non-existent. As a result, it effectively eliminates dead zones within a home or office, allowing devices in those areas to connect to the network more reliably. While a router is essential for creating a wireless network by distributing internet connectivity, it does not necessarily enhance signal strength beyond what is already provided. Similarly, a modem connects to the internet service provider and translates the internet signal for use by local devices, but it does not extend signaling coverage. A network switch, on the other hand, is used to connect multiple wired devices in a local area network but does not play a role in managing or extending Wi-Fi signals at all.
