How Does WiFi Work?
WiFi works by using radio waves to transmit data between devices. When a device, such as a laptop or smartphone, is connected to a WiFi network, it uses a wireless adapter to send and receive data to and from a nearby wireless router. The wireless router is connected to a physical network, such as a cable or fiber optic connection, and acts as a bridge between the wireless and wired networks. The data is transmitted between devices using a specific frequency of radio waves, typically in the 2.4 GHz or 5 GHz range.
The data transmitted over WiFi is encrypted to prevent unauthorized access, and devices must be configured to use the same network name (or SSID) and password in order to connect to the same WiFi network. WiFi networks can be either public or private, with public networks often providing open access to anyone in range, while private networks require authorization to access. Many devices, including laptops, smartphones, and tablets, come with built-in WiFi capabilities, making it easy to connect to the internet or other devices without the need for cables or wires.
What Is The Difference Between WiFi And Wireless?
While the terms WiFi and wireless are often used interchangeably, they actually refer to slightly different things. Wireless refers to any type of communication or connection that does not use physical cables or wires, such as radio waves, infrared, or satellite communications. WiFi, on the other hand, refers specifically to a type of wireless networking technology that uses radio waves to connect devices to the internet or other devices.
