Compare DVI and HDMI | What is the difference
DVI and HDMI are digital video signal transmission interfaces. They are designed to connect external displays — to a computer, tablet, game console, or generally any device capable of playing video. However, there is a fundamental difference between these two standards. In this article, we will describe in detail the difference between these two protocols…

What is the difference between active and passive 3D
Modern 3D TVs offer two technologies for «three-dimensional visualization» of content — active and passive. And there is a rather serious difference between them, which manifests itself not only in price, but also in the quality of the display. But to understand the difference between active and passive 3D, you need to know how «3D…

Compare SATA 1.0 and SATA 2.0 | Important differences
SATA 1.0 and 2.0 differ in data transfer speed. On the first generation, the maximum throughput is 150 megabytes per second, on the second — 300 megabytes per second. This difference is due to the different clock frequency of the interface. However, there are a few subtleties. The above velocities are «spherical and in vacuum».…

Comparing USB 2.0 and USB 3.0 standards
Technological progress in relation to computers is especially pronounced. Almost every year new technologies, interfaces, systems, chips and other architectures are introduced. This also affects such familiar things as USB. So, for example, starting from 2017-2018, the USB Type-C interface began to be actively introduced. It has a symmetrical, oval connector, and is generally not…

Compare DirectX 9 and Direct 11
Even computers bought “for study” are now and then used for games. And the developers of the Windows operating system understand this very well, integrating libraries and mechanisms for interacting with a video card directly into the kernel code. And DirectX is just such a tool. In general, DirectX is a set of application programming…

Compare DVI-I and DVI-D | Important differences
DVI is one of the most common interfaces in the mid-price segment for connecting a computer and a monitor. It is he who can be found on budget and inexpensive video cards, as well as on office and home displays with resolutions up to Full HD inclusive and refresh rates up to 60 Hz. DVI…

Comparing hibernation and standby in Windows
Old operating systems of the Windows family — for example, XP and the «seven» — are quite interesting work with data. They were originally created for low-performance computers, so the built-in mechanisms imply work with outdated hardware. And most clearly this is manifested in the presence of two modes of suspension — sleeping and waiting.…

Compare thermal paste and thermal pad | What is best for a laptop
Due to the design features, laptops very often suffer from overheating. All components are located close to each other, and the air inside the case practically does not circulate — and that is why the temperature of the «iron» rises almost exponentially. Overheating, in turn, leads not only to a decrease in performance due to…

Compare AHCI and IDE
The vast majority of modern hard drives involve connecting to a computer via the SATA interface. It provides a high data transfer rate while maintaining the reliability of this very information (that is, it is exchanged quickly and without errors). However, SATA is a physical interface. That is just a cable and two connectors. At…

How an IP camera differs from an analog one: description and differences
When designing a video surveillance system, engineers need to solve a huge number of problems associated with both laying cables and choosing cameras directly. Moreover, today there are a huge number of their varieties on the market, which further complicates the determination of the appropriate type. But the two types of video surveillance cameras that…
