What is the meaning of wifi ?

Wi-Fi, which stands for “Wireless Fidelity,” is a technology that allows devices to connect to the internet and communicate with each other wirelessly within a local area network (LAN). It enables data transmission between devices such as smartphones, laptops, tablets, and other electronic devices without the need for physical wired connections.

Here’s a brief overview of how Wi-Fi works:

  1. Wireless Router: A Wi-Fi network typically starts with a wireless router, which is connected to an internet source, such as a broadband modem. The router creates a wireless signal that devices can connect to.
  2. Wireless Network: The router broadcasts a Wi-Fi signal, which is essentially a radio signal that carries data. This signal can cover a certain area, often within a home, office, or public space, known as a Wi-Fi hotspot.
  3. Wi-Fi Devices: Devices equipped with Wi-Fi capabilities, like smartphones, laptops, and tablets, can detect and connect to the wireless network by selecting it from a list of available networks and providing the appropriate password if necessary.
  4. Data Transmission: Once connected, these devices can send and receive data over the wireless network. This data can include internet access, file sharing, streaming media, and more.
