सामान्य प्रश्न
61. What is Wi-Fi technology, and what are its key provisions relevant for the UPSC exam?
Wi-Fi is a wireless networking technology that allows devices to connect to the internet or other devices wirelessly using radio waves. Key provisions include its operation in the 2.4 GHz and 5 GHz frequency bands, the use of routers for data transmission, and security protocols like WPA3. Newer standards like Wi-Fi 6 and Wi-Fi 6E offer faster speeds.
परीक्षा युक्ति
Remember the frequency bands (2.4 GHz and 5 GHz) and the latest standards (Wi-Fi 6/6E) for prelims. For mains, understand its applications and security aspects.
2. How does Wi-Fi technology work in practice, and what role do routers play?
Wi-Fi uses radio waves to transmit data between devices and a router. The router acts as a central hub, receiving data from the internet and transmitting it wirelessly to connected devices. It also receives data from devices and sends it to the internet. Routers operate in specific frequency bands and use protocols to ensure reliable data transfer.
