Quick Response (QR) Code: Definition and Working of QR Code.

Quick Response Code which is popularly known as QR Code has become part of our daily life so quickly in just a couple of years. This technology is quite old but now we use it everywhere for various purposes like making online payments, getting product details from packages, sharing event tickets, and more. Let's learn more about QR codes and how they work.

What is a Quick Response (QR) Code?

A Quick Response (QR) code is a two-dimensional barcode that can store various data types, including text, URLs, contact information, and more. A scanning device such as a smartphone camera or dedicated barcode scanner is used to read the information stored in a QR code. 

It was first developed in 1994 by a Japanese company called Denso Wave, which is a subsidiary of Toyota. QR codes gained popularity due to their ability to store more information than traditional barcodes and their quick readability.

How does Quick Response (QR) Code Work?

QR, or Quick Response, codes are two-dimensional barcodes that store information in a matrix pattern of black squares on a white background. The process begins with data encoding, where the desired information, such as a URL or text, is translated into a matrix structure.

To generate a QR code, we use QR code generators, which can be standalone applications, features within mobile apps, or online tools. We input the data and configure settings like error correction levels and size, and the generator transforms this information into a distinctive black-and-white pattern.

We can print the generated QR code on paper, or we can display it on a digital screen or physical media. We position our scanning device to capture the QR code and the image undergoes processing to identify the black square pattern. 

The decoding software then interprets the QR code pattern as binary data. The binary data, representing the original information, is then converted back into its original form.

The final stage involves the action or display of the decoded information. The user may be directed to a website, presented with text, or prompted to perform a transaction, depending on the nature of the encoded data. 

Note: QR codes often integrate error correction mechanisms. These mechanisms enable the reconstruction of data even if parts of the code are damaged or obscured during the scanning process. This robustness is especially useful for maintaining functionality in less-than-ideal scanning conditions. (alert-passed)

Difference Between Quick Response Code and Barcode.

QR code is basically the advanced version of a barcode but still, there are many differences between them, and here we have listed a few.

Difference Between GTX and RTX Graphics cards.

GTX Vs RTX

GTX and RTX is not a simple technology to explain in one or two lines. However, the fundamental difference between GTX and RTX is that is the latter has been specially designed to support ray-tracing techniques. This is itself is a complicated concept but, in essence, it means plotting the precise paths of light sources as they bounce around a virtual environment.

So, in a game world that features a character with a glass-visored helmet, for example, light from the sun might first hit the visor, and then bounce off a building window and then to and off the watch face on another character’s wrist and so on. Clearly, this involves extraordinarily complex mathematics and billions of calculations each and every second.

GTX Vs RTX Graphics Cards.

NVIDIA's graphics cards are categorized under two main series: the GeForce GTX series and the GeForce RTX series. Here are some key differences between the RTX and GTX graphics cards:

1. Ray Tracing Capability:

RTX Series: The major differentiator for the RTX series is the inclusion of dedicated hardware for real-time ray tracing, called RT Cores. Ray tracing is a rendering technique that simulates the way light interacts with virtual objects, creating more realistic lighting, shadows, and reflections in supported games and applications.

GTX Series: GTX cards generally lack dedicated hardware for real-time ray tracing. While they can still handle traditional rendering tasks effectively, they may not perform as well in games or applications that leverage ray tracing technology.

2. Tensor Cores and DLSS:

RTX Series: RTX cards also feature Tensor Cores, which are designed for AI (Artificial Intelligence) tasks. This includes DLSS (Deep Learning Super Sampling), a technology that uses machine learning to upscale lower-resolution images in real-time, providing improved performance without sacrificing image quality.

GTX Series: GTX cards do not have dedicated Tensor Cores for AI-related tasks. DLSS and other AI-based features are exclusive to the RTX series.

3. Performance and Architecture:

RTX Series: RTX cards are built on the NVIDIA Turing architecture. They generally offer improved performance and efficiency compared to previous architectures, especially in tasks involving ray tracing and AI.

GTX Series: GTX cards are based on various architectures, such as Pascal and earlier. While they can still deliver excellent performance for gaming and other graphical tasks, they lack some of the specific hardware features introduced with the Turing architecture.

4. Price Range:

RTX Series: RTX cards are often positioned in the higher-end market segment, and they tend to be more expensive due to the additional hardware features like RT Cores and Tensor Cores.

GTX Series: GTX cards cover a wider range of price points, including more budget-friendly options. They provide a good balance of performance for users who may not require the advanced features found in the RTX series.

5. Use Cases:

RTX Series: Ideal for gamers and professionals who demand the latest technologies for realistic graphics and enhanced performance in ray-traced games, 3D rendering, and content creation.

GTX Series: Suitable for gamers and users who prioritize performance for traditional gaming and general graphics-intensive tasks but may not require the advanced features offered by the RTX series.

NVIDIA Graphics Card.

NVIDIA GeForce RTX platform offers real-time ray tracing and AI for an entirely new gaming experience. RTX graphics card offers stunningly accurate lighting like shadows, reflections, refractions, and global illumination. With more realistic scenes, gaming is more intense and exhilarating than ever before.

RTX graphics the card can cast up to 10 Giga rays per second, allowing real-time, movie-like lighting in games and it is possible because RTX graphics cards deliver up to 6x faster ray-tracing performance.  

The older graphics processor, including NVIDIA’s own GTX series, might be able to manage ray-traced graphics effects but such chips are not specifically designed for these next-generation visuals.  

The two big company who manufacture graphics cards is NVIDIA and AMD, here is the list of their graphics card base on increasing order of performance. 

In a few year ray-traced effects in games will become normal and GTX will be eliminated for RTX.
