What is the main purpose of using WiFi technology?

The main purpose of using WiFi technology is to allow wireless communication between devices. WiFi utilizes radio waves to create a local area network (LAN) that enables devices such as computers, smartphones, tablets, and other smart devices to connect to the internet and communicate with each other without the need for physical cables. This wireless communication provides flexibility and mobility, allowing users to access network resources from various locations within the coverage area of the WiFi network.

In contrast to connecting devices with physical cables, which limits movement and can create clutter, WiFi provides a convenient and efficient way to maintain strong connections while on the go. Though WiFi can contribute to secure file sharing and might impact internet speed, these are not its primary purposes; rather, they are secondary benefits that stem from the main function of facilitating connectivity without wires.
