Interesting information about how electronics manufacturers deceive buyers. Read more.
The amount of available memory
In the description of smartphones and tablets in the first place is often displayed memory. This is because that in fact is the only strong contrast within range of the device. IPhones are divided into 16, 32 and 64 GB, because everything else is the same. With android situation is similar. The main question is whether or not the user is at their disposal precisely this amount of memory for storing your data? Of course not.
An excellent example here are the plates Surface from Microsoft. Carefully read the description of the model, which we proudly served as a top "128 GB Surface Pro». 89 GB available to the user. Ok, look at the "64 GB Surface Pro» - 28GB available. The rest goes under the system. We look at the 64 GB iPad - available approximately 57 GB. We look at the top-end smartphone Samsung Galaxy S4 16 GB - about 8 GB available.
Units of measurement
The size of the hard disk - it will never match the description. When yours truly bought ultrabook on Windows with 128 GB SSD, he worried whether it would be a total deficit of the place? And when he saw the inclusion of 104 GB, and this is without taking into account the space occupied by the system.
So it is with HDD. Read the 500 GB, 465 GB see. Why? The thing in the units. Manufacturers use drives "GB = 10 degree 9", while technically uses Windows "gibibyte = 2 to the power 30».
This is complete nonsense. The producers discs 1 kilobyte = 1000 bytes, 1 MB = 1000 kilobytes, and 1 GB = 1000 MB. In Windows 1 kilobyte = 1024 bytes, 1 MB = 1024 kilobytes, and 1 gigabyte = 1024 megabytes. How to count the same hard disk volume 500 gigabytes in the system? 500 * 1000 * 1000 * 1000 / (1024 * 1024 * 1024) = 465.66 GB.
4G, which is actually a 3G
Generally, the term refers to the generation 4G mobile communications, which includes in the future will include emerging technologies that implement the data rate to mobile objects equal to or greater than 100 megabits per second.
In fact, the development of technology has given rise to the intermediate generation, and many of the technologies relate in due time to the third generation, for some reason suddenly "grown" to the fourth, but in fact do not meet specifications. A good example may be the situation with the US telecom operator AT & T: after update iOS 5.1 users have seen as an indicator of the network changed from 3G to 4G. This does not mean that their iPhone 4 and 4S suddenly learned how to connect to LTE networks. Just wanted to operator to its network designated as network 4G, 4G though there was no smell.
Now label 4G stuffing anywhere, he lost his sense and meaning.
[Color = # 000099] Retina and other cool words
Removal of the brain to the consumer the most featured (and meaningless) a combination of letters and words - this is the norm. Take any device with a screen: Sony has «TruBlack» and «X-Reality Picture Engine», at Toshiba «TruBrite», at Nokia «ClearBlack» and «PureMotion HD +».
What does all this mean? Yes, what a difference, most importantly, that this revolutionary unique technology is only for us, and if you do not buy our product is, you definitely die. Apple has a Retina screens. Only Apple has a Retina display. Really? But technically Retina - it is only a certain measure ppi, and this figure has long been surpass several other manufacturers. But Retina is a registered trademark and can not be used by another, which is why only Apple has the Retina display. If it were not for the fact that other producers would appear Retina-Retina, Retina-Retina-Retina, Super Retina HD +++ and things like that.
For Wi-Fi ready - not ready
With a high probability you will come across a term such as Wi-Fi Ready. They flashed on the player and TV. What does it mean Wi-Fi Ready? No, the device is no Wi-Fi module, but it is ready to connect the module, and then work on a wireless network. Why is this? There are two goals at once: to settle in our minds the idea that the function as it is in the device, and even knock out money from us for the same module, which can cost several thousand.
When submitting such a product manufacturer also can cheat. The fact that the screen size, and the diagonal region immediately display images may differ. All this is aimed at our not always understandable desire to compete gigs, kernels, and other indicators of inches, meaning that we can not understand.
Expensive digital cables
There are so-called "elite" companies that produce "luxury accessories". An example is a company Monster, which makes terribly expensive cables for digital formats such as HDMI. What is the superiority of such a cable? In fact, in anything. If it is a digit, then the wires are ones and zeros, and the only thing that is required of such a cable - conductive metal / alloy and structural integrity, allowing the signal to inform the receiving device. There are no bells and whistles are important only in the analog cable, where the requirements for the conductivity of the wire and insulation are much higher, but figures it's all too much.
[Color = # 000099] Battery Life
We have long ceased to be surprised by the fact that the practical use of the device battery life it is different from the manufacturer. Why is this happening? Obviously, to present your product as efficiently as possible. Internal testing device on battery life occurs at very specific conditions that are very different from the actual practice of using the product.
In this post we touched on only a few points that you should pay attention when dealing with vendors and advertising. There are still many useful tips related to a particular type of equipment and accessories, and we hope that in the comments you share them. The most useful of them form the next post in this series.
