MYTHS Pics Tech



Technology is growing by leaps and bounds every day. Its development has reached a point where we all have become its slaves. Most of us would blindly follow every technological rule that catches our attention without stopping to investigate its authenticity. This is one habit that we must quit. With new technology flaring up every minute, it is high time that we bust some of the myths related to it. So, here are the 10  popular technology myths debunked for you.

1. Myth: Leaving your phone plugged in the charger all night damages its battery.                 

Truth: Your smartphone is called so for a reason. Smartphones come with a “battery cycle” of their own. A smartphone battery has only a limited number of charges, after which it starts degenerating.

An authentic smartphone battery comes with an ingrained chip whose main function is to prevent charging beyond its 100% capacity. So, the only thing you should worry about is buying your smartphone from a verified retailer.

However, the rise in temperature when the phone remains plugged into a charger for a long time might deteriorate its battery life. All the modern-day smartphones have lithium-based batteries. Because of this, an overheated phone can degrade its battery. This doesn’t mean that putting your phone on charge for the whole night will degenerate your battery life, but a little precaution goes a long way. Also, in most cases, discharging your phone all the way to 0% before charging it again acclimatizes the battery. (source)

2. Myth: The more megapixels a camera has, the better the picture it takes.                               

Truth: It’s not the megapixels but camera sensors that add quality to a photo. These sensors convert light into electrical signals which eventually add colors to every picture. The camera’s lens, composition, controls, and circuitry are other key factors responsible for producing a fantastic picture.

Take into account that the more pixels, the smaller the area size in the sensor to catch the light (the color) corresponding to every pixel and, therefore, the higher the precision must be in both the sensor and the lenses. So much so that there have been cases with camera models from well-known brands whose megapixel resolutions were reduced when the next models were released.

Basically, if you use a poor camera and poor lenses with more megapixels, you will have poor-quality pixels. Or, conversely, if you already have a good camera or smartphone, do not worry if a new model has just been released. Your photos are not going to have much less quality than the newer model.

So, the key ingredient here is the sensor of your phone. It works as “the film” of the camera. It allows the light to pass through it, translates the light into an electronic signal and, finally, processes it to produce a high-quality image. (source)

3. Myth: Using your phone at a filling station can lead to a fire explosion.                               

Truth: There has been no documented case of this up to now. To ignite gasoline vapors, you need high voltage. Mobile phones use less voltage than what’s essential to start a fire.

The cast of the popular TV series Mythbusters attempted to explode a mock gas station with a working cell phone surrounded by gasoline vapor. A specific concentration of fuel and air is needed for the gas to explode. So, Jamie Hyneman sprayed a highly flammable vapor into the glass chamber that already had a mannequin with a cellphone inside a car. The myth was soon busted.

So, what fuelled this idea?

Electromagnetic waves, which travel from these smartphones to the closest network tower, are the real culprit here. The energy these waves carry is somewhere around 1.24 mega electron-volts to 12.4 peta electron-volts. This is considered to be a good amount of energy. So, it is assumed that these waves can create a voltage that might ignite gas vapor. The truth is that the voltage of a cell phone battery is usually quite low, so much so, that it loses the potential to start a fire, and you can forget an explosion. (12)

4. Myth: Deleting files from the Recycle Bin ensures permanent deletion.                               

Truth: Deleting files from the Recycle Bin or Trash only means that your OS has marked the area empty. Even though it seems that the file data has been wiped off from your computer, it’s still there.

Emptying the Trash or Recycle Bin doesn’t automatically guarantee that the files have been wiped from your computer. It means that they are only removed from the list of files that are on the system. If you want to recover a file that’s been deleted from the Trash or Recycle Bin, you will have to dabble in various data recovery software. Any skilled techie can very easily recover the de-allocated file (the files deleted from the Recycle Bin or Trash). For permanently deleting your files, you will have to overwrite the free space after their de-allocation. Microsoft offers a free command-line utility called “Sdelete” that prevents data recovery. (source)

5. Myth: Airport X-ray scanners are harmful to you and your devices.                                         

Truth: Airport X-ray scanners do not cause any harm to your devices or to you, for that matter. A very low dose of X-ray hits you when you stand between the detectors. It is not possible to get any damage done under such low radiation.

X-rays can harm you only if your body is exposed to a large dosage. So, when you pass through the scanners at airports, the X-rays are directed toward you in a measured proportion. This means that the radiation emitted out of the scanners is extremely low in dosage. It bounces off your skin rather than going through your body. The average radiation exposure is considered to be .15 uSv (a unit of radiation) which is lower than the scanners used for official purposes.

Even the American College of Radiology and the American Roentgen Ray Society has declared that the effect of X-ray scanners at the airport doesn’t cause any potential harm to people. Even flight-induced cosmic radiation has a higher dosage than that of airport scanners. So, no, they aren’t dangerous for you or your devices. (source)

6. Myth: Lowering the resolution of an image also lowers the file size of the image.               

Truth: The file size of an image depends on its pixel dimension. When you lower the resolution, it doesn’t change the size or number of pixels. Thus, the size of the file remains the same.

Pixel dimension is the number of pixels measured in width and height of an image. Image resolution solely depends on the PPI, which is the number of pixels exhibited per inch of an image. A high-resolution image has more pixels as compared to a low-resolution image. Most people think that lowering the resolution of an image will also lower its file size when its resolution depends on the pixel dimensions. You can practically prove it by reducing the resolution in applications, such as Photoshop. Select the “Resample” option to run this test.

When you change the width, height, or even the resolution of an image, its size will remain the same. However, when you decrease the dimensions of a pixel, you will notice the difference in the image’s size. The file size of an image also depends upon its format and amount of compression. (12)

7. Myth: More RAM means a faster computer.

Truth: RAM does not work to make your computer run faster. It makes it better at multitasking. Period.

RAM is one of the main components of a computer and almost every app is executed from it. Contrary to the popular belief, upgrading your RAM to 8 GB does not speed up the working of applications on your computer or stream your video games better. However, it does help in running software such as Photoshop, Outlook, Firefox 5, and other editing apps, smoothly. So, if you have a lot of applications running in the background of your computer and you want to play video games simultaneously, a RAM of 8 GB is preferable over 2 GB. The main purpose of RAM is to allow your computer to work on a lot of things at once, not faster. So, unless you are a professional gamer, video editor, or graphic designer, your system will run absolutely fine even with 2 GB of RAM. (source)

8. Myth: Clearing your apps on your phone somehow saves battery and makes it run faster.   

Truth: It does the opposite and you should know how. Every time you open an app, it has to reload itself. Frequent reloads of these applications start consuming a perceptible amount of your battery. This results in the reduction of your battery life.

No, closing a running app on your smartphone doesn’t save its battery life. Also, if an app is running in the background, it doesn’t necessarily mean that it is using up your battery. This myth has lingered on for years, and finally, both Apple and Google have addressed it.

It all began when a fan sent an email to Tim Cook, the CEO of Apple. He asked if quitting multitasking apps frequently saves battery life. Craig Federighi, the head of software development, replied in the negative. In fact, quitting apps reduce battery life by consuming a considerable amount of it when they are restarted.

This is how it happens. When you constantly open and quit apps, the battery resources eventually start getting used up. Yes, closing your apps regularly in hopes of saving the life of your battery makes it worse. It even hampers the performance of your smartphone. Well, that’s some information now, isn’t it?

Both Google and Apple have also stated that it’s better to leave them in a paused state. However, restricting data usage and reducing notification helps in saving your phone’s battery. (12)

9. Myth: More signal bars guarantees great cell service.         

Truth: Signal bars only indicate your proximity with the nearest signal tower.

One of the biggest myths about mobile networks is that if there are more bars on your cell phone, then your the network of your cell phone is great. Here’s how we will debunk it. Have you ever wondered why two cell phones with different signal bars can make quick and easy calls at the same time? They both perform equally, even if the count of signal bars on their screens isn’t the same. That alone should make us question the authenticity of the relationship between signal bars and cell service.

But network bars do have a purpose. The reality of it all is that network bars signify the proximity of the nearest network tower. The number of bars your cell phone shows, the closer is the tower. (12)

10. Myth: LCD (Liquid Crystal Display) and LED (Light Emitting Diodes) TVs use different technologies altogether.

Truth: The only difference between an LCD and LED is that an LCD TV has cold cathode fluorescent lamps (CCFL’s) to provide back-lighting, whereas LED TV’s use an array of smaller, more efficient light-emitting diodes (LED’s) to illuminate the screen. An LED TV is an LCD TV with an LED back-light.

There are many technology myths related to LCD and LED TVs. The most popular of them all is that they both use different technologies. Well, that isn’t quite true. Both LED and LCD TVs are built with two layers of polarized glass which allows the liquid crystals to pass through them. When you look into the finer details, the only significant difference between the two is their backlights.

LCD monitors come with a backlighting technology, known as CCFL, short for cold cathode fluorescent lamps. LED monitors to come with LEDs or light-emitting diodes. That is it. LEDs are more expensive because they use full-array backlighting technology. But that doesn’t make LEDs better than LCDs. However, LEDs do help in the reduction of energy consumption, but other than that, there is nothing that truly sets them apart technologically. LEDs are technologically advanced, and thus, more in use these days. (123)
