Living in a modern age, we're constantly surrounded by all sorts of tech. We're so used to it, that we don't even notice how ingeniously designed it really is. And there are a lot of small mysteries. Here are 5 things you use every day, but it holds secrets from you.[br][br]1. USB trident logo[br][br] [br][br][br]Third party image reference[br][br]USB inserted upside down wouldn't even work. So, every USB plug has the USB trident logo only on the upside. Just to make sure you see it facing you, and plug it in.[br][br]2. Striped mini jack[br][br] [br][br][br]Third party image reference[br][br]Maybe you've noticed that the plug on your headphones has those little stripes between the metal parts. Their main purpose is to separate different channels of electric impulses that transfer information. Those with one stripe could provide only a mono-sound signal. Two striped plugs can separate two signals and that helps to transfer stereo-sound. Three stripes mean that your headset can not only play sounds in stereo, but also has a microphone in it.[br][br]3. Phone charger symbols[br][br][br] [br][br]Third party image reference[br][br]The CE mark tells this charger has passed all the quality tests and is good enough to use. A little house symbol tells you that this device is only suitable for house use. The double square shows that your charger has double insulation and you're well protected from electric shock. The crossed out trash can tells that the charger needs to be recycled as tech waste. And last, if there is 'I' before 'V' - this charger is standard for the U.S. If there is only 'V' - this charger meets standards for Europe too.[br][br]4. Ferrite beads[br][br] [br][br][br]Third party image reference[br][br]If you're in front of a laptop, just look at the end of its power cable, near the plug. There it is - the big cylindrical lump of black plastic. Ever wondered what it's good for? The ferrite bead acts as a signal suppressor, which cancels all random noises.[br][br]5. Keyboard legs[br][br][br] [br][br]Third party image reference[br][br]Having a keyboard in a flat position is actually better for your wrists. These legs are only here to help you see the letters you're typing more clearly.[br][br]source techindia
