What is Wifi

Wi-Fi or wifi?
What is Wi-Fi? Alot of people are not clear when it comes to explaining what Wi-Fi is and how it works. To learn more about WiFi and understand it better, we will talk of Router, access points and hotspot
Wi-Fi is a wireless technology used by Wireless Local Area Network (WLAN). This technology is used in devices that are Wi-Fi enabled to connect to the internet. For Wi-fi to connect to the internet it uses a router that has Access point or Hotspot. Access point and Hotspot can be used interchangeably depending how it is being used.
What is a Router? In computing terms a router is a networking device that connects devices between computer networks.
What is an Access point? This is the connection that a WIFi device uses to conect to the internet. An access point works together hand in hand with the router.
What is a hotspot? This is a physical location where one can connect or have access through a Wifi that uses an access point to connect to the router that connects to the internet or in this case an internet service provider. Hehe quiet alot huh?

Hotspot Area [Wi-Fi device ->via, an access point -> router device -> Internet]

In simple terms, other areas do indicate there's hotspot  in bound. Turn on your Wi-Fi device, it detects an access point. Connecting to this (either for free or any mode of payment), you connect to the router. This router connects you to the internet.

Furthermore, Wi-Fi is useful in many ways. You can also connect two devices to share files locally. A good example is "shareit app", two devices can conect and share files amongst each other. In this context, a modern device is capable of becoming a hotspot that broadcasts it self as an access point. The other device joins the network by, firstly being in the hotspot area to detect the access point. One device will act as a client (requesting files or services) and the other the server (providing files or services). By clients and services, remember that for the connection we need a Wi-Fi device and a Router. Client is the Wi-Fi device and Server is the Router. This is what is called mobile hotspot. Besides sharing files, using the same way devices can also share internet. This is very common but poor connections and not exactly knowing how Wi-fi works brings large misunderstandings. The concept is all the same, modern devices can either be a client or server, sometimes viceversa during usage.

Mobile hotspots are found under settings, once turned on the access point becomes available and when the other device detects this broadcast they can easily connect (using a passphrase or no passphrase needed). Once this connection is established, the phone broadcasting the signal or with available WLAN can turn on data to share to the client device.

Data Charges may vary to what device is connecting to the server. Lastly, take note you can share internet connection from your phone to your laptop, console etc via this method. Have an internet dongle out of your own will
