WiFi

Wireless Fidelity (Wi-Fi) is a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. Wi-Fi is based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards. Wi-Fi is used for a variety of purposes, including connecting laptops, smartphones, tablets, and other devices to the Internet, as well as for creating wireless networks in homes, businesses, and public spaces.

How Wi-Fi Works

Wi-Fi works by using radio waves to transmit data between devices. A Wi-Fi network typically consists of a wireless router, which is connected to the Internet, and a number of devices that connect to the router wirelessly. The router broadcasts a signal that the devices can pick up and use to connect to the Internet. Wi-Fi signals can travel through walls and other obstacles, making it possible to create wireless networks in a variety of environments.

Benefits of Wi-Fi

Wi-Fi offers a number of benefits over wired networks, including:

• Convenience: Wi-Fi allows devices to connect to the Internet without the need for cables, making it easy to move devices around and connect to the network from anywhere within range of the wireless signal.
• Flexibility: Wi-Fi networks can be easily expanded to accommodate additional devices, making it easy to add new devices to the network as needed.
• Security: Wi-Fi networks can be secured using a variety of methods, including encryption and access control, to protect data from unauthorized access.
