HOW DOES THE WIFI WORKS IN AEROPLANESHOW DOES IT WORKS.?


Have you ever wondered how actually the Wi-Fi in an airplane works? Traveling in the airplane has been a phone-free zone for a lot of years. We have to turn off our electronic devices and rely instead on movies and in-flight magazines for fun. But times have changed.
Airplanes have tried to make flying a little more enjoyable by offering us in-flight wireless internet, but have you ever wondered how exactly does Wi-Fi work when you are on an airplane?


When Wi-Fi first became a thing in the airplane in the early to mid-2000s, it usually worked by transmitting an internet connection to a transponder attached to the plane using satellites, similar to how folks in rural areas without cable DSL or fiber infrastructure use satellite dishes to get online.
Even in the present days, those old systems are still in use. There is a system named air-to-ground transmission or also called as ATG. These are similar to cell phone towers. These have the benefit of being a cheaper than satellite internet, but they work over land, and there are few disadvantages not only do these towers suffer from geographical restrictions, but the service they provide can be painfully slow as anyone who’s ever tried to stream anything on a plane probably knows.

the atg systems don’t offer speeds that are high. the speed would be somewhere around five megabytes per second, but the satellite internet is faster with speeds of up to 50 megabytes per second. there are ku band, the same range of spectrum used to be satellite tv which we use in our house. with many people flying on airliner, a 50 megabytes connection can be very slow if lots of passengers are connected at the same time. the tech we have available requires airlines to get large antennas onto their planes  these will be heavy enough to have a heavy effect on the plane’s weight and aerodynamics which leads to higher fuel costs that are passed along to you.
nowadays, major air carriers are now starting to install cob ka-band satellite antennas which have the potential due to their higher bandwidth to reach hundreds of megabytes per second, enough for streaming even on a full plane where lots of people are trying to connect.

Ever get tired seeing a sea of yellow folders on your machine ? Whether you like different colors, folder organization or just plain customization, there would have come a time when you would’ve gotten bored with the monotonous nature of the windows explorer. Mac OS fortunately allows its users to make changes to folders, but Windows lacks it. Fortunately for us though, we live in the internet age. So when users asked for a way to change folder colors and style, Microsoft may not have heard, but quite a few other people did. Quite a few software now exist, that will let you change the color and style of the folder icons. Today, we show you one of these – Folderico.

Small one to see but how its works in your computer.

In a computer, a jumper is a pair of prongs that are electrical contact points set into the computer motherboard or an adapter card . When you set a jumper, you place a plug on the prongs that completes a contact.



In effect, the jumper acts as a switch by closing (or opening) an electrical circuit. Jumpers can be added or removed to change the function or performance of a PC component. A group of jumpers is sometimes called a jumper block .



The plug and play initiative was designed so that users did not have to deal with jumpers. Today, computers come with preset jumpers, although some manufacturers provide jumper settings in the instruction manual so that the owner can reset the jumpers if they want to customize performance.



In electronic test equipment, a jumper cable is used to make a temporary contact between two points for the purpose of testing a circuit

Whatsapp Suspicious link detection

Particularly in Watsup, many dangerous links are circular today. Clicking on them will be in danger. For instance, the F Big Bajar company is offering a shoping vocher worth of 5000 rupees in the case of 17th anniversary , and a message will be circular in Whatsapp. See how the official website link will be viewed, as well as the link looks the same way most people click on it blindly before thinking back.



It's also a phishing attack that will steal your personal information immediately. In many cases, the most popular type of business companies and websites are circled by many dangerous links via Whatsapp. The newly launched Suspicious Link Detection has been introduced to Watsup to prevent this. Whatsapp Beta 2.18.206 version is available for users who use it.




Whatsapp will now see each link that is shared by Whatsapp, and closely …
