History of Wi-Fi Internet
Introduction:
In today’s digital era, Wi-Fi internet has become an essential part of our daily lives. From browsing the web to streaming movies and connecting with friends and family, Wi-Fi has revolutionized the way we access the internet. But have you ever wondered about the origins of Wi-Fi and how it has evolved over the years? In this article, we will delve into the fascinating history of Wi-Fi internet, starting from its humble beginnings to its widespread usage today.
1. The Birth of Wi-Fi:
The story of Wi-Fi internet dates back to the late 1980s when the Federal Communications Commission (FCC) released a portion of the radio spectrum for unlicensed use. This decision opened up opportunities for companies to develop wireless communication technologies, and it laid the foundation for the creation of Wi-Fi. The term “Wi-Fi” itself was coined by a brand consulting firm called Interbrand in 1999.
2. The Invention of Wireless Ethernet:
In 1991, a group of researchers at the Netherlands-based NCR Corporation developed the first wireless Ethernet system, which laid the groundwork for Wi-Fi. This system used a frequency-hopping spread spectrum (FHSS) to transmit data wirelessly. However, it was not widely adopted due to its limited range and slow speed.

do facebook stories notify screenshots
Facebook Stories are a popular feature on the social media platform that allows users to share temporary photos and videos with their followers. Similar to Snapchat and Instagram Stories, Facebook Stories have gained immense popularity over the years and have become an integral part of how users interact on the platform. However, one question that often arises among users is whether Facebook Stories notify screenshots. In this article, we will delve into this topic and provide you with all the information you need to know about Facebook Stories and screenshots.
Firstly, let’s understand what Facebook Stories are and how they work. Facebook Stories were launched in 2017 and are a way for users to share photos and videos that disappear after 24 hours. These stories appear at the top of the Facebook app, and users can view them by tapping on their profile picture or on their friends’ stories. Users can also add filters, text, stickers, and other interactive elements to their stories, making them more engaging and fun.
Now, coming to the main question, do Facebook Stories notify screenshots? The short answer is no. Unlike Snapchat, Facebook does not notify users when someone takes a screenshot of their story. This means that you can take a screenshot of someone’s story without them knowing. However, there are a few things to keep in mind before you go on a screenshot spree on Facebook Stories.
Firstly, although Facebook does not notify users when someone takes a screenshot of their story, the person whose story you have screenshot might find out if they check their “Seen By” list. When you view someone’s story, they can see who has viewed it by tapping on the story and swiping up. This brings up a list of people who have viewed the story, and if you have taken a screenshot, your name will appear on the list. So, even though Facebook does not notify the user, they can still find out if they check the list.
Secondly, it is essential to respect people’s privacy on social media platforms. Just because Facebook does not notify the user, it does not mean that you can take screenshots of their stories without their permission. If someone has shared a personal or sensitive story, it is best to ask for their consent before taking a screenshot. It is crucial to remember that what you share on social media is not always meant to be saved or shared by others.
Another thing to keep in mind is that Facebook does not have a direct screenshot feature for stories like Snapchat and Instagram. This means that to take a screenshot, you will have to use your phone’s native screenshot feature, which can be a bit tricky as it requires you to press multiple buttons simultaneously. However, there are third-party apps available that allow you to take screenshots of Facebook Stories without any hassle.
Furthermore, it is worth noting that Facebook has been testing a feature that would notify users when someone takes a screenshot of their story. This feature was spotted in testing by a few users in 2018, but it has not been officially rolled out yet. So, it is possible that in the future, Facebook might introduce this feature, but for now, screenshots on Facebook Stories remain undetected.
Apart from taking screenshots, many other actions on Facebook Stories are not notified to the user. For instance, if someone shares your story on their profile, you will not receive a notification for it. Similarly, if someone takes a screenshot of your Facebook post, you will not be notified. This is because Facebook believes in giving users the freedom to share and interact without constantly being notified about every action.
In addition to Facebook Stories, the platform also has a similar feature called Messenger Day, which allows users to share temporary photos and videos with their friends on Facebook Messenger. The same rules apply to Messenger Day as well, and users are not notified when someone takes a screenshot of their story.
In conclusion, Facebook Stories do not notify screenshots, but there are a few things to keep in mind before taking a screenshot. It is crucial to respect people’s privacy and ask for their consent before sharing their stories or taking a screenshot. While it is understandable that users might want to save or share interesting or funny stories, it is essential to remember that everyone has the right to privacy on social media platforms. Facebook might introduce a notification feature for screenshots in the future, but for now, screenshots on Stories remain undetected.
