WiFi

 

Wi-Fi is a technology that allows devices such as computers, smartphones, tablets, and other gadgets to connect to the internet or to each other wirelessly. Wi-Fi is short for "Wireless Fidelity" and is based on a set of wireless networking standards called the IEEE 802.11 protocols.

To use Wi-Fi, you need a device with a Wi-Fi adapter and a Wi-Fi network, which is usually created by a device called a router. The router is connected to the internet via a wired connection, such as a cable modem or DSL modem, and it broadcasts a wireless signal that Wi-Fi-enabled devices can detect and connect to.

When you connect to a Wi-Fi network, your device sends a request to the router, which then authenticates the device and assigns it an IP address. Once the device is connected, it can send and receive data packets wirelessly to and from the router, which then routes the data to the internet or other devices on the network.

The Wi-Fi signal operates on a specific frequency band and uses a technique called radio frequency (RF) signaling to transmit data wirelessly. The RF signals are transmitted and received by antennas, which are built into the devices and the router.

The speed and range of a Wi-Fi network depend on a variety of factors, including the strength of the signal, the number of devices connected to the network, and the type of Wi-Fi standard being used. Wi-Fi standards have evolved over time, with newer standards offering faster speeds and more reliable connections.

So, Wi-Fi is a technology that enables wireless communication between devices and networks. It uses radio frequency signaling and relies on a router to create a wireless network for devices to connect to. Wi-Fi is a convenient way to connect devices to the internet or to other devices without the need for cables.
