Wi-Fi is a wireless technology that connects computers, tablets, smartphones, and other devices to the Internet.
Wi-Fi uses a radio signal sent from a wireless router to a nearby device, which translates the signal into data you can see and use. The device transmits a radio signal to the router, which connects to the Internet via cable or cable.
Wi-Fi network: A Wi-Fi network is simply an Internet connection that is shared with multiple devices in a home or business through a wireless router. The router is directly connected to your Internet modem and acts as a hub for transmitting the Internet signal to all of your WiFi-enabled devices. This gives you the flexibility to stay connected to the Internet as long as you are within your network's coverage area.
How does Wi-Fi work?:
WiFi uses radio waves to transmit data from your wireless router to your WiFi-enabled devices, such as your TV, smartphone, tablet, and computer. Because they communicate with each other via radio waves, your devices and personal information can become vulnerable to hackers, cyber-attacks, and other threats. This is especially true when you connect to a public WiFi network in places like coffee shops or airports. When possible, it's best to connect to a password-protected wireless network or personal hotspot
WiFi vs Hotspot:
Wi-Fi: Wi-Fi is a wireless communication technology that uses radio frequency waves to connect mobile devices to the internet and allows communication between them without actual cables. It’s like a wireless local area network that transmits and receives radio waves within devices based on IEEE 802.11 network standards. Wi-Fi operates on the traditional 2.4 GHz radio frequency band to connect devices within a fixed range. It is one of the most popular means of wireless communication and the best example of a Wi-Fi home network. The router receives the signal coming from outside the network like your ISP and transmits it back to your mobile devices such as mobile or laptop.
Hotspot: A hotspot is nothing but a physical location like a wireless access point that provides internet access to mobile devices typically using Wi-Fi. It allows devices to communicate with each other via a wireless local area network that creates a portable hotspot using a modem or wireless router that is connected to an ISP. The term hotspot is synonymous with wireless internet access. An access point is nothing but a networking device that obtains internet access via Wi-Fi. In simple terms, hotspots refer to physical locations typically public places like cafes, hotels, or airports where users can access the internet wirelessly.
