10 Popular Technology Myths Debunked for You

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. (1, 2)


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. (1, 2)


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. (1, 2)


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. (1, 2, 3)
