What does the word noob mean?

An article about Vk slang would not be complete without such a sometimes offensive title as noob. The original meaning of this word in English was - newcomer. Let's say, a person who has very little experience playing this or that game. Nowadays, the word noob is very often perceived as offensive, since it means that a person does not know how to do something at all. For example, you play , and they say to you: “What a noob!” This means that you don’t know how to play at all. Today, noob can also be applied to any of the fields. Noob at work, noob at the computer, and so on.

We really hope that now, at least a little, the slang in VKontakte has become clear to you.

0 People who are constantly stuck in world wide web, use various emoticons and interjections when communicating, the meaning of which is not always clear to middle-aged and older people. Therefore, the website was created specifically so that you can find answers to your questions. Have you bookmarked our resource? Be sure to do this, because we post new information every day. Today we’ll talk about a fairly famous expression in Internet jargon, this HD, which means you can read it a little later.
However, before you continue reading this publication, I would like to recommend you a couple more educational texts on the topic of Internet slang. For example, what does Ku mean, what is Vstr, what does Virt mean, how to understand the word Helpani, etc.
So let's continue What does HD mean?? This term was borrowed from in English" ", and is graphical display laughter.

HD- these are symbols indicating a laughing emoticon, it shows that you are very funny

In general, you can rarely meet people on the Internet who would never use it when communicating. emoticons. Although beginners sometimes have a question about what HD means, to which they themselves are not able to answer.

Initially, such emoticons were developed in the English-speaking part of the Internet, but then after a while they appeared here too.
If you look at the "XD" emoji, you might not immediately see a laughing face in it. Let me give you a hint, the letter “X” expresses eyes closed from laughter, and “D” is a mouth opened wide from laughter. If you still don't understand, just mentally rotate the XD so that the "X" is at the top and the "D" is at the bottom, that is, rotate the picture exactly 90 degrees.

Speaking in simple words HD- this is a Russified image of a big “laugh”, and is a complete analogue of its English counterpart “XD”. True, according to the unwritten rules of the Internet, you need to write “XD”, but those who type “XD” instead are simply lazy or do not want to change the keyboard layout. Over time, the English-language emoticon began to be used less and less, using Cyrillic characters instead.

This laughing icon is used in cases where you want to show your invisible interlocutor how much fun you are having. For example, if you watched a funny pic, read funny status or saw a funny video. Today this expression of emotions "HD" has truly become one of the most popular emoticons in different chats, in social networks and so on.

After reading this article, you learned HD, what does this mean in VK, and now having discovered these two mysterious letters again, you will not get into trouble, and you will be able to answer them adequately.

Before purchasing a new monitor, laptop, TV, or even smartphone and tablet, many users ask the question of how Full HD differs from HD.

For some reason, all devices with Full SD will always cost more than those with just SD. The problem is that on the Internet you can find articles that supposedly answer this question, but after reading them the question still remains open.

The reason for this is that the entire text is written absolutely incomprehensibly. There are even certain tables, but it is almost impossible for an inexperienced person to understand what is meant there.

Therefore, today we will try to answer questions as simply and easily as possible regarding what HD is, what Full HD is and how they differ.

And we will start by simply giving designations to the terms with which we will work in the future.

1. Glossary of terms

Resolution is the number of pixels in each unit of image dimension.

Scanning is a method of displaying video. In our case, only two types are used - interlaced (when using this method, next to the resolution the letter “i” is indicated, that is, for example, “1920x1080i”) and progressive (indicated by the letter “p”, for example, “1280x720p”).

Interlaced scanning is when each frame is divided into two, which are called half-frames. In this case, the image is divided into lines and transmitted to the screen through the line.

Odd lines are placed in the first half-frame, and even lines are placed in the second half-frame.

Progressive scanning is when all the lines of a frame are transmitted sequentially, one after the other. In this case, the frames are divided only into lines.

2. Differences between Full HD and HD

Permission

The very first thing worth saying is that Full HD and HD are resolution formats. HD stands for " High Definition", that is " a high resolution».

Accordingly, Full HD means “full high resolution” (if translated literally). To be precise, the HD resolution is 1280x720 pixels.

In the case of Full SD and SD, the unit of image dimension is taken physical dimensions screen.

Based on the above definition, it turns out that there will be 921600 (1280 times 720) dots on the screen - the length of its horizontal side will be 1280 dots, and the length of the vertical side will be 720 dots.

It turns out that the original image will be transmitted at 921600 pixels, so its clarity will be very high.

Clue: For marketing purposes, resolution is often referred to as the length of the vertical side of the screen. For example, to indicate HD resolution (1280x720), they often say 720p. To refer to Full HD they say 1080p or 1080p Full HD. Do not confuse this designation with the designation of the sweep!

Actually, Full resolution HD is 1920x1080, which is as many as 2,073,600 pixels. This is the most important difference - Full HD resolution is higher than just HD.

Therefore the quality transmitted image will be significantly higher.

Today there is great amount formats. In the figure below you can see a complete list of them and the resolution of each.

Scan

Without going into details, let's say that Full HD quality supports interlaced scanning without changing the image.

In HD, interlaced scanning with picture changes is supported.

It is quite obvious that when an image is divided into lines and then into frames, some element may get lost somewhere and the resulting image will be distorted.

Also, the lines may not be transmitted in the same order as they were initially.

But it is important to understand that even interlaced scanning with image distortion is supported by slightly modified HD, but not the standard one with a resolution of 1280x720.

Standard HD quality supports exclusively progressive scan. Full HD supports both interlaced and progressive scan, and even some combinations of them.

Of course, there are many more differences between 1080p Full HD and regular 720p HD, but this moment knowledge about resolution and scan will be quite enough to choose the right smartphone, tablet, TV or monitor.

conclusions

Here are the main differences between Full HD and HD:

• Full HD provides higher image quality due to the increased detail that is achieved big amount pixels.
• Full HD can display images in resolutions of 1920x1080, 1920x720 and 720x576. HD only works at 1280x720.
• HD only supports progressive scan, while Full HD supports two types – progressive and interlace.
• The HD standard implies very high requirements for the technology on which it is reproduced. Full HD is less demanding on devices.
• IN Full devices HD is usually very powerful processors, which has a positive effect on the speed and number of functions.

3. Don't fall for advertising gimmicks!

Today, most stores actively offer to buy devices with Full HD. At the same time, some consultants don’t even really know what HD and Full HD are.

But in some cases this permission It will simply not be relevant for the simple reason that the human eye will not be able to see the difference between HD and Full HD on some devices.

And in this case, paying 500-700 dollars more (in the case of TVs) for the presence of Full SD simply does not make any sense.

You need to understand that on some devices Full HD is simply not necessary.

So, Full HD resolution does not make sense in such cases:

• When the screen diagonal is less than or equal to 32 inches (for TVs and monitors). At this resolution, the difference between HD and Full HD is not particularly noticeable, unless you look closely at each pixel with a magnifying glass or binoculars. In addition, 32-inch TVs that support Full HD often use technologies that provide a very poor color gamut (specifically, 8-bit matrices).
• When we're talking about about smartphones and tablets, even with a 5 or 10 inch screen. IN in this case Image quality is influenced by a huge number of factors. For example, if we talk about screen technology, then Super AMOLED screens always better than IPS, even if the latter has 10 times higher resolution.

And in general, you shouldn’t hang your ears when a young and interesting seller spouts a lot of numbers and talks about how good it will be to show this or that device.

It’s better to pick it up, watch a few pictures and videos, play a video, and compare it with other devices.

If you like it, then you can buy it - this is the best best criterion choice.

Often, when viewing descriptions of films or videos, you can see a note indicating that the video is offered in HD quality.

Intuitively, this means higher than normal image quality. If you want to better understand the gradations of video stream quality, let's try to do this together.

What does "HD" mean?

Abbreviation HD stands for "High Definition", or "high definition" . This means that a frame of an HD video signal contains at least 720 progressive scan lines or 1080 interlaced scan lines.

Video in this quality can be broadcast as TV signal and is called HDTV, and is also recorded on laser discs in HD DVD and Blu-Ray formats. Not all computer displays can display videos of such clarity, but only those whose characteristics include the mark “HD ready” or “HD ready 1080p”.


To watch videos and films in HD quality, you need a computer with a powerful enough video card to display the image. HD video provides high-definition images and is much easier on the eyes than older video standards.

Software for HD playback on computer

If the processor or video card power of an old computer is not enough to high-quality reproduction HD video, you can try to take advantage of the features software Windows. The operating system installed on your computer contains special means to speed up video stream playback. This set of functions is called DXVA (DirectX Video Acceleration).

It is directly designed to enhance the hardware capabilities of the video card and offload power central processor. It is enough to enable DXVA mode on your computer for the HD image to be significantly improved during playback. If you do not have this functionality pre-installed, you can install it yourself, using, for example, a set of commonly used codecs K-Lite Mega Codec Pack.

HD quality formats

Today, high-quality video exists in two main formats: regular HD and Full HD.


For regular HD, the typical frame size is 1280 x 720 pixels. Video files are packaged using formats Matroska (mkv) or MP4.
Full HD video first appeared thanks to Sony in 2007. The standard frame size for it is 1920 x 1080 pixels.

It is noteworthy that HD formats use the 16 x 9 standard, in which the horizontal frame width is increased compared to the old 4 x 3 standard. Therefore, often when played back on a screen with inappropriate proportions, the image turns out to be either too stretched in width or elongated in height. However, this does not greatly affect the perception of the film or video.

Perspectives HD video

In Japan, work has been going on for a long time to create an ultra-high definition video format (UHD or Ultra High Definition). The frame size in it already reaches 3840 x 2048 pixels, and in the longer term even 7680 x 4320 pixels are planned. Not today yet great need in household use so high standard image quality.

These devices find their niche in professional fields– in the production of computer special effects, video surveillance high level, space technologies, etc.


There is no doubt that in the next decade, ultra-high image quality will displace the HD and Full HD formats we are familiar with today. It's just a matter of creating a cheap-to-produce medium for recording such large volumes of information.

If in HD quality today it “weighs” about 7-8 GB, then an ultra-clear image will require an increase in memory capacity by 2-4 times. Once this problem is resolved, we will be able to enjoy watching videos and movies in incredible high quality Images.

In search of the truth, I had to visit more than one forum and more than one chat. All efforts are made to find out the true history of the appearance of HD. I was met with a variety of answers and no less surprising questions. Monosyllabic and lengthy, stupid and sensible... But I acquired a little funny knowledge in the process of my non-standard, but by no means meaningless research. I pursued a good goal - to finally find out what HD means and why I see it so often in messages. It seems my work won't go down the drain XD.

Holotropic Breathwork? Negligent doctor? I want to go home? Cunning guy? Data store? Do you know what the abbreviation HD means? You didn’t guess, and it’s not an abbreviation at all, but an emoticon. The story of its appearance is this: once upon a time there was a smiley face XD. According to all the rules of modern emoticon, X is eyes closed, for example, in pleasure, and D is reminiscent of a joyfully smiling mouth. If we try to turn our head 90 degrees, it will seem to us that XD looks like a laughing face, so we used it in appropriate cases - when we wanted to emphasize that what was written made us laugh; indicate that the writer is experiencing fun.

But, as often happens, sometimes unexpected changes occur. This did not escape our XD either - many users, when inserting this emoticon, often forgot, or were even simply lazy, to switch the keyboard layout. Yes, it’s still necessary in capital letters highlight! Without bothering ourselves with excessive clicking on the keyboard, we typed xd, xd. Over time, the interlocutors stopped asking what kind of icon this was and how this abbreviation stood for, and they themselves began to answer that way. Stick - stick - cucumber, so the little man came out. So we now have an analogue for a cheerful smiley. An ingenious and simple invention that saves the nerves and time of those who communicate on the Internet XD. Russian-language tracing paper is increasingly being used on many resources, and is increasingly finding a response.

If anyone asks a question about the purpose of this wonderful symbol, they are often beginners who do not have much experience in Internet communication. And real users are already using this icon with all their might, denoting intense fun. It was not in vain that it was adapted to our harsh forum reality. Or maybe he adapted himself, and XD is the result of the evolutionary development of the original XD. But his ancestor did not become extinct and continues its activities, although more and more in the vastness of America and Europe. By the way, they say that on foreign pages our original users are recognized by the illiterate and inappropriate saturation of their posts with this very thing XD.

They convey their emotional state with different emoticons, but the notorious HD is one of the most common. Laughing with your eyes closed seems to be fashionable these days. This emoticon, as emoticons are also called, is appropriate in many situations.

Maybe this is because humor has been a universal tool for many years now? And in an age when the word Internet was akin to a dirty word and in an age when a three-year-old gentleman helps his mother reinstall operating system, laughter was held in high esteem. He was both a means and an end. With its help, conflicts were smoothed out, the number of charged ions in the atmosphere was reduced, and the strongest knots were cut. And the current HD, or, as you wish, XD is just an echo of the great and simple that we have to face. This tiny HD contains our goodwill, hospitality, common sense, and subtle humor. And we, without thinking about it, again and again mercilessly hit the keyboard in anticipation of the treasured XD...
