HOW WI-FI WOULD LOOK IF WE COULD SEE IT

Wi-Fi  is a form of electromagnetic field transmitted as waves. The electromagnetic waves consist of electric and magnetic waves travelling perpendicular to each other. Its in a range of frequency that the human eye can't detect

An idealized Wi-Fi data transmitted over a band that is divided into different sub-channels, which are shown in various colours.

Wi-fi fields are usually spherical (like the one) or ellipsoidal.The crest of Wi-Fi waves are understood by computers as 1. The troughs are equivalent to a 0. 

                                                

   Ultimately, these chains of 1s and 0s form an intricate pattern that is then translated into the audio, video and data that make up websites.
Wi-fi waves travel through space as rapid, data encoded waves.A freeze frame of these pulses would show that the pulses are about 6 inches apart (as shown).

Wi-Fi waves are three to six inches from crest to crest- not as long as radio waves, but definitely not as short or as harmful as microwaves.

Objects such as trees can obstruct the signal such that it has to be augmented by multiple wi-fi routers placed in different positions.

   Routers, instead of sending out a single wave, take a range of wavelengths, chop them up and transmit them simultaneously. The average home Wi-Fi signal can project up to 30 feet. They can pierce through walls easily, but water is hindrance. Plants can sometimes impede Wi-Fi signals too. The Wi-Fi that is available in public spaces is much more powerful and can transmit signals up to 150 feet.

Wi-fi routers affixed to buildings, lamp posts and other object create a circular data field around them. These antenna have anomnidirectional signal that extends equally in all directions.

Which means that even though we can never see them, we are surrounded bythese waves of data all the time. And since there is increasing demand among consumers for more connectivity, the amount of data in the air will just keep increasing. Consumers want access to more data and higher speeds.  But there is a limited amount of space on the electromagnetic spectrum and tech companies are fighting for spots.

Dealing with Shortcut Virus

Dealing with Shortcut Virus:

The most common virus menace for Windows users is the shortcut virus changing all your files and folders in pen-drive to shortcuts. It's a familiar problem among most college students. We have all tried to use the ineffective shortcut virus remover, a third party software, to solve the problem. But it is very simple to deal with.

1. Delete all the shortcuts from the pen-drive. They can be identified by the arrow symbol in icons and having a size of less than 4 kb usually.
2. Now open command prompt.
3. Go to the pen-drive by typing <alphabet assigned to drive>:
4. Now enter the magic line attrib -s -h /S /D
5. Wait for some time... It's done! All your files and folders are back.

The secret behind this:
The virus only changes the folders' system attributes, makes it hidden and creates shortcuts. So by removing the shortcuts, and removing the hidden and system attributes from all files and folders, you have terminated the virus without trace!

IS the Battery Dead or Working? Wanna Know?

1. 

Note- This only works with Alkaline Batteries. Don't try this on Other batteries like Lithium Ion batteries .

Hmm So why does This Happen?

A theory is that the Alkaline in the Discharged battery creates a Gas At the Anode End Giving the battery more buoyancy. Due to increased buoyancy the battery bounces more than once. It is not Exactly a skill, But it is Damn useful.
