“Wireless fidelity” refers to wifi, a technology enabling devices to connect to the internet without physical cables. Wi-Fi transmits data over radio waves, making it convenient for mobile devices and laptops to access network resources easily. It typically uses standards set by the Institute of Electrical and Electronics Engineers (IEEE), such as 802.11. Through routers, Wi-Fi allows multiple devices to connect simultaneously, enhancing productivity and communication. This technology has revolutionized how people access information, connect with others, and utilize smart devices in their daily lives.
