The WiFi full form or full name of WiFi is “Wireless Fidelity/”. It is a popular Wireless Networking Technology. There is an AC technology, through which we are using Internet and Network
Connection today.

What Is WiFi?
Now understand in your easy language, this0 is the technology through which we are getting the facility of Internet in our smart phones, computers, laptops in a wireless way.
Through this, we and you can connect to the Internet within the confined space. Nowadays, everyone accesses Internet through WiFi and simultaneously transmits data wirelessly as you do with Share it and Xender. WiFi has emerged from the wireless and Hi-Fi Sabbath.
WiFi is a standard. Following the standard we connect computers to wireless network. As of now, there are as many Smartphone, Laptop, Printer and Computer. All of them have a WiFi chip. Through which we and you connect to Wireless Router and use Internet.
Once wifi is enabled, once wireless Router is connected then you can access internet. But Router also uses DSL and Cable Modem to stay connected to the Internet. Otherwise Internet Access is not there.
WiFi is similar to Hi Fi, whose full form is High Fidelity. The full form of WiFi is not wireless Fidelity, it is just a name. Selected by WiFi Alliance. It is also known as WLAN.
It uses Technology Radio Waves. You use the Internet while walking.
Who invented WiFi?
Wi-Fi was invented by John DeSullivan and John Deane in 1991.
History of WiFi
WiFi was born on 1985. When the United States FCC announced that Wireless Frequency 900MHZ, 2.4 Ghz and 5.8 Ghz anyone can use it without License. Then its history was started.
Sayed you would not know these bands were used in home appliances like Microwave. Therefore it was believed that they have no use. Especially there is no use in communication. Therefore, to make this band usable, the FCC made it mandatory to use it. Named Speard Spectrum Technology.
The license of Spread spectrum technology was taken on 1941. George Antheil and Actor Hedy Lamarr were to take the license. This was the technology through which signals were sent with multiple frequencies. Nothing should happen with this change, but after this technology, there was a lot of improvement in wireless signals after this technology.
This technology failed to solve Interference Problems. Because at that time there was already Radio Install in Mobiles. Due to which the quality of signals was greatly affected.
At the same time, a technology was emerging, named WLAN (Wireless Local Area Network), which had a lot of technical problems. As such there was no standard of WLAN. Many problems had to be faced in connecting different company devices.
In 1988, the then NCR Corporation required a wireless Cash Register. That is why he, with the cooperation of Victor Hayes and Bruce Tuch, attempted to make the Institute of Electrical and Electronic Engineers (IEEE) a standard. In 1997, the standard was fixed and the name which was quite attractive was "802.11". It was published in 1997 itself.
At that time the speed of DATA Transfer in 802.11 Standard was around 2 megabits Per Second. In 1999, 802.11a was published. Whose speed was around 54 Megabits Per Second. It was quite expensive, so its next version was published, which was named 802.11b, it was launched by WiFi Technology, this version was cheaper and the range of this network was also much higher.
802.11b In a very short time, due to being popular, there was a kind of fence of Wireless Technology. It had established its position in the hardware market very fast. Due to the range and compatibility it was quite famous.
For this reason, 6 companies got together and formed a Wireless Ethernet Compatibility Alliance, or WECA. Through which it was tested whether there is WiFi Copitability.
In 2002, he derived the words Wi-Fi, Wireless and, a term HiFi. The name of which came to be known after a few years from the Wi-Fi Alliance. Now you must understand what is the history of WiFi.
How Wifi Technology Works
Nowadays everyone is using WiFi. Whether it is in Office or at home or in Hostel but no one knows how this technology works. First of all we need an Electronics Device to use this technology.
Which is called Wireless Transmitter / Hub / Router. This device creates WiFi Network. This Wireless Device (Router), Receives Information through Broadband Connection. Now there are some components inside it.
Which converts this information into Radio Waves. This device emits these Converted Waves outside. A small area of Wireless Signals is created through this process. Which we call WiFi zone.
This small area takes the form of a WLAN (wireless Local Area Network). There are all the devices in this small area like Smartphone, Laptop, Printer if all these devices have built-in Wireless Adapter. With the help of which one can easily get WiFi Signal.
Remember one thing if a mobile phone is connected to WiFi. Understand that the device has a wireless adapter. Due to not being strong Radio Signals, the distance of this network remains limited. Like inside and around a house, to the side of the road. Meaning its range is from 10 to 20 Meter.
Radio Waves can easily go beyond the wall. For this reason, the facility of Internet is also available in nearby rooms. However a wireless router is enough for a house. The more Router you go to the Internet, the faster the network will run, the stronger it will be.
When you send some information (Text, Image, Audio, Video) back to the Wireless Transmitter / Router, the same process will run opposite. Like you are connected to WiFi, I mean your mobile. EX- You have sent text messages to your friend.
It converts to Radio Waves before exiting Message Mobile and after reaching the signal to Transmitter / Router. Transmitter / Router text is converted into signal and transmits to Broadband and in that the address of Receiver is there. You must have known, this is how WiFi works.
Important Information - There are some devices like Mobile, Laptop, and Tablet in which the Wireless Adapter is already inside. This is the reason why most smartphones get Internet facility through WiFi. There are some such as Desktop does not have wireless Adapter in them.
That is why they have to buy a wireless card or Adapter. Which is then inserted into the desktop's USB port. Which we can also access in Desktop.
Conclusion
