We pass on stereotypes, prejudices and myths across generations. In particular, they are about technology. And such information can be stored in the minds of people for years — even after it has been refuted. Today, when any information can be easily obtained by clicking the mouse, it is even more surprising that most people believe in these myths. Here are the 6 most common ones.
Megapixels don’t mean picture quality
The figures blinded demanding customers, and they began to assume that the more megapixels are, the better the picture is. Marketers are actively using this and megapixels are the first characteristic of a smartphone. Megapixels really show how powerful the camera’s sensor is, but for amateur footage, it is not so important.
Cameras use an array of thousand hundreds of microscopic light sensors called pixels. They convert the image into an electronic signal structure. The quality of a digital photo depends on the number of pixels and their physical size. A very large number of pixels provides the high resolution required to capture fine details in the frame. But a large number of pixels means that there will be a lot of small pixels, and small pixels create much more “noisy” images than large ones. This is especially noticeable in low light. This means that in certain conditions, a camera with a 6-megapixel sensor can provide better photos than a camera with an 18-megapixel sensor. So quantity will not always determine quality.
A Phone is Better to Charge Аfter Full Discharge
The idea that you should always completely discharge a battery before you charge it appeared a couple of decades ago. And before it was really like that. But this idea has nothing to do with modern technologies.
The fact is that the phones used to use nickel metal hydride (NiMH) and nickel cadmium (NiCad) batteries. Such batteries had a so-called “memory”: if the battery was not completely consumed before recharging, it “remembered” how much energy was used up and charged only up to that amount. The constant repetition of such actions led to the fact that the battery was never fully charged.
Now in our phones and laptops, there is a lithium-ion (Li-ion) battery. Such a battery has a limited number of charge cycles before it stops holding the total power. This is also not very happy. But there is a solution to how to extend the life of the battery. You just need to charge the phone from time to time and not let it sit down to 0%. This will mean that you are not using a full charge cycle. It is ideal to keep the phone constantly in the range of 40−80% charge. In fact, the biggest enemy of modern batteries is temperature. Do not overload the phone or laptop. The colder the battery is, the more you can extend the life of the gadget.
Charging the Phone all Night Can Kill the Battery
As it was mentioned above, modern phones work on lithium-ion batteries. They are advanced enough to stop charging when the battery is fully charged and there is no real threat of damage to the battery. Although, even when the phone is fully charged, it still consumes current. Therefore, it is better to turn off the device after fully charging to save money on electricity.
MAC Cannot Catch the Virus
We hurry to upset you. Apple computers are just as vulnerable to viruses as other computers. Another thing is the frequency. Viruses really attack MACs less than other PCs.
There are several theories about this. When the company appeared on the market, the percentage of people with MAC was so small that it was inappropriate for them to create a virus. Malicious software gets more benefits from attacks on a more common system. Another version is that MAC has a better operating system with fewer weak points. There are many opinions, but there is one fact — MAC is less susceptible to virus attacks, but there is no immunity from them.
The Computer Must be Turned off at Night
There are several arguments in favor of the daily shutdown of the computer: it saves energy, does not allow the fan to suck in even more dust. But this does not affect the performance of the computer itself. On the contrary, turning the computer on and off puts it under additional load. A good compromise that will allow saving electricity is simply to turn off the monitor if the computer is not used for a while, or to put it into sleep mode. If after that the device is unstable, the reboot can return it to normal operation. If that does not work, it is time to scan for malware.
Telephones Cause Cancer
Cell phones emit electromagnetic radiation in the form of non-ionizing radio frequency waves. To date, the only known side effect of these waves for people is that they can generate a small amount of heat in the part of the body that is closest to the telephone in use. Medical studies have shown that a lengthy telephone conversation will force the side of the brain against which the phone is leaning to absorb more glucose than the opposite side of the brain. Any possible health effects of this discovery are unknown.
Cell phones work by sending and receiving signals from nearby communication towers using radio frequency waves. Like FM radio waves, these waves are a form of non-ionizing radiation. They do not have enough energy to cause cancer by directly damaging the DNA inside the cells.
“Mobile phones emit low levels of radio magnetic waves. A number of studies have been conducted to investigate whether radiation leads to brain tumors or increases the risk of cancer. Until now, there has been no conclusive evidence,” Dr. Sanjay Dudhat, senior consultant and surgical oncologist, Nanavati Hospital, Mumbai, says.
Although still there are side effects of using the phone: poor concentration, eye fatigue and devaluation of your life. And everything else is in order, there is no harm.
Full-HD has poorer quality than quad-HD
Full-HD means 1920 x 1080 pixels and quad-HD is 2560 x 1440 pixels, and the human eye is unable to distinguish beyond 326 pixel/inch. So, it really doesn’t make a huge difference whether you buy full-HD or quad-HD.
