WiFi (short for "wireless fidelity") refers to a technology that allows devices to connect to the internet or communicate with each other, wirelessly, using radio waves. WiFi utilizes the IEEE 802.11 standard protocols for wireless local area networking (WLAN). It provides internet access to devices such as smartphones, tablets, laptops, and computers, enabling data transfer and communication without requiring physical connections.
WiFi networks operate by using a wireless router or access point, which acts as a hub to connect devices within its range. The router uses radio frequency signals to send and receive data, typically on the 2.4 GHz or 5 GHz frequency band, depending on the specific equipment and network settings.
To connect to a WiFi network, devices must have a WiFi adapter or network interface installed, with which they can detect and connect to available networks. Once connected, the device can access the internet or communicate with other devices on the same network.
WiFi has become widely popular due to its convenience, flexibility, and mobility. It allows users to connect to the internet in various locations, such as homes, offices, cafes, airports, and public spaces where WiFi networks are available. It has revolutionized the way people use the internet and simplified the access to online resources, services, and applications, making WiFi an essential component of modern connectivity.
