What is the main difference between Wi-Fi and hotspot?
The main difference between Wi-Fi and hotspot lies in their functionality and purpose. Wi-Fi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables or wires. On the other hand, a hotspot is a physical device or a feature on a device that provides internet access to other devices through Wi-Fi.
In simpler terms, Wi-Fi is the technology that enables wireless connectivity, while a hotspot is a device or feature that uses Wi-Fi to provide internet access. For example, a smartphone can be used as a hotspot to provide internet access to a laptop or tablet, but the smartphone itself is connected to the internet through cellular networks.
How does Wi-Fi work?
Wi-Fi works by transmitting data through radio waves at a specific frequency, typically 2.4 gigahertz (GHz) or 5 GHz. When a device is connected to a Wi-Fi network, it sends a request to the Wi-Fi router, which then authenticates the device and grants access to the network.
