Wi-Fi hotspots 

A Wi-Fi hotspot is a wireless access point that allows devices to connect to the internet using Wi-Fi technology. It acts as a gateway between a local area network (LAN) and the internet, providing wireless connectivity to devices such as smartphones, tablets, laptops, and other Wi-Fi-enabled devices.

Wi-Fi hotspots can be created using various methods:

Mobile Hotspot: Many smartphones can function as Wi-Fi hotspots by enabling the "Hotspot" or "Tethering" feature in the device settings. This allows the phone to share its cellular data connection with other devices over Wi-Fi.

Dedicated Hotspot Devices: There are standalone devices available, often called mobile hotspots or Mi-Fi devices, that are specifically designed to create Wi-Fi hotspots. These devices have their own SIM cards and connect to cellular networks to provide internet access.

Portable Routers: Portable routers are similar to dedicated hotspot devices but typically require an external source of internet connectivity, such as a wired Ethernet connection or a USB modem. They create a Wi-Fi network by connecting to the internet through the provided source.

Public Hotspots: Public places like cafes, airports, libraries, and hotels often offer Wi-Fi hotspots for visitors to access the internet. These hotspots are usually password-protected or may require users to accept terms and conditions before connecting.

When a device connects to a Wi-Fi hotspot, it can access the internet through the hotspot's internet connection. The device communicates with the hotspot using the Wi-Fi protocol, allowing data transmission between the device and the internet.

It's important to note that using public Wi-Fi hotspots may pose some security risks. It's advisable to use secure websites (HTTPS) for sensitive activities, avoid accessing personal or financial information, and consider using a virtual private network (VPN) to encrypt your internet traffic and enhance security when connected to public Wi-Fi networks.
