Wi-Fi stands for “Wireless Fidelity” and is a technology that allows electronic devices to connect to a network and the internet without physical cables. Think of Wi-Fi as an invisible cord connecting your devices to the internet using radio waves. It’s a technology designed for Local Area Networking (LAN), which means it provides internet coverage within a specific area like your home, an office, or a coffee shop. This wireless technology is based on a family of technical standards called IEEE 802.11.

To understand how this works, let’s explore the core components that make this wireless connection possible.
