Users are in the habit of believing common «truths» about technology without questioning them. Often this belief doesn’t benefit either the user or their device. All sorts of misconceptions are spread not only by incompetent users, but also by hardware manufacturers or software developers for their own benefit.
Let's start with the burning topic of energy consumption.
Agree that your grandmother has more than once unplugged your computer at night. If it was off it was no big deal, but if it was on, and moreover it loaded «heavy» files — it was a shame in the morning. For sure, it was done under the motto «No need to waste electricity».
The fact is that when the computer is switched off, it consumes such a tiny amount of energy that the meters don’t even count the consumption. On the other hand, turning off the power from a running computer can harm it, this common truth is true.
By the way, leaving your phone on charge overnight doesn't hurt your phone or your wallet when you pay the bills either. The charge controller in every smartphone limits current consumption after the battery reaches a certain level of charge. So once the phone is charged, until you unplug it, the power supply will simply maintain a 100% charge level.
Let's talk about viruses.
This is a hot topic for careless Internet users. There is an opinion that only Windows users need to worry about viruses. The lucky owners of Mac OS computers or Linux users can sleep well, as viruses for these operating systems are simply not developed. That isn’t quite true.
Malware is developed for all operating systems, but it is really best spread among Windows users. There are several reasons for this fact:
- The majority (about 80%) of Windows users are constantly working in accounts with admin rights, accordingly, «caught» viruses get the same rights.
- Linux and the Mac OS share the typical UNIX roots. Traditional computer viruses are unable to function in a UNIX environment.
- Apple products are secured by their own software repository. All files downloaded from the App Store are thoroughly checked, and completely infected software is weeded out.
- Linux and MacBook users have minimal privileges and cannot make changes to system files.
- Warning, unconfirmed fact :) Linux users differ from all the others in suspiciousness, attentiveness and in-depth knowledge so that their computers are more difficult to infect.
- We shouldn't forget about the banal number of users of different operating systems. According to data from Internet agency UAWEB in Ukraine and in the world there is such a distribution:
Logically, the more users, the more successful attacks, the more new viruses will be written specifically for this segment.
Now about the quality of communication.
Admit it, do you also judge the quality of your upcoming phone call or file download speed by the number of sticks on the connection indicator? It doesn't matter if it's a mobile network or Wi-Fi, the indicators show signal strength, which shows the distance to the signal source, not the quality of the connection.
Expectations about the quality of connection won’t be justified if the channel on which your Wi-Fi works, is overloaded, or you are with the phone not only near the tower, but also from a powerful source of interference. And also, no matter how good the connection is on your side, if the desired site is overloaded with requests or your companion in the deaf woods, you shouldn’t wait for a quality connection.
The next block is dedicated to those who like to enjoy images in high resolution.
The fact is that the manufacturers of monitors, trying to impress users with inexorable growth of resolution indicators, don’t take into account the capabilities of the human eye. Top 8K picture format (7680x4320) can be appreciated only on monitors with diagonals of about 70 inches. About a year ago the first 8k TV actually went on sale, which costs only 12 thousand euros:)
So if you want to enjoy a top-end picture, you will have to shell out some money. On smaller screens viewers are unlikely to be able to really discern the difference.
We also don’t recommend users to chase the number of megapixels in the camera when choosing a phone. Today, the resolution of smartphone sensors is very high, but not everyone understands how to use it properly. For example, camera developers LinX from Israel were able to create a camera with only 4 megapixels, the results of which surpass the pictures from the 16 megapixel camera in the Samsung Galaxy S6.
Choose and use your technology wisely, check and question ridiculous advice.
