The Difference Between LCD, LED, Plasma Monitor

LCD (Liquid crystal Display) uses a solid florescent back light to light up individual pixels in different ratios between red, green, and blue to get your colors. The color black is achieved by blocking the light in a certain pixel, but the problem here is that you can never get true black with LCD screens because there is still a light on behind it making the color actually more of a charcoal gray. When electrical current flows through the liquid, the crystals move, and the polarized glass allows certain wavelengths of light from the bulb to pass through. This creates thousands of tiny dots, or pixels, of color that ultimately make up the picture on an LCD TV.

LEDs (light-emitting diodes) have been around for decades, but their introduction into TV design is a fairly recent development. LED televisions employ standard LCD technology but with one crucial difference – the handful of backlight lamps that traditionally illuminate the LCD screen are replaced by a larger number of tiny LEDs. This enables LED TVs to be much slimmer than their LCD counterparts.

Plasma tvs work differently.  Plasma TVs were developed in response to the weaknesses of LCD displays. Like LCD displays, a plasma screen TV has two panes of glass that make up the flat screen. Rather than using liquid crystals, plasma TVs have chambers filled with xenon and neon. When electricity runs through these chambers, the gas converts into plasma; as the plasma moves through the chamber, it emits photons that display in various colors.

The pros and cons to each LCD and Plasma are: 

LED (Light-Emitting Diode)

Pros	Cons
Superb picture quality	Quite expensive
Slimmer than other TVs	As it's slimmer, you lose  sound quality
Considerably lower power  consumption
Can be viewed from more  angles than an LCD
Has a long lifespa

LCD (Liquid Crystal Display)

Pros	Cons
Reasonable prices	Poor viewing angles, so you're restricted to how high you can place it
Comes in a variety of different  sized screens	Average lifespan is 60,000 - 80,000  hours of viewing
Less chance of pixel burn-out  than Plasma TVs	Slow response times means the picture  on the screen will take longer to update
Brighter image and a cooler  running temperature
Lightweight

Plasma

Pros	Cons
Great range of larger sized screens	Average TV lasts around 60,000 - 80,000  hours of viewing time
Can view the screen from high  angles	Prone to pixel burn out, which can be too  pricey to fix
Fast pixel response time, giving you  a clearer picture. Especially when watching live,  fast-paced shows	Hefty power consumption
Newer models are becoming more  reliable

nowadays, many people buy LED TV. Given the dwindling availability of LCD TVs and the ongoing demise of plasma TVs, most TV buyers will go for an LED set, and that’s no bad thing considering that they're getting a slim and energy-efficient television.
However, bear in mind that picture and sound quality on LED TVs varies hugely between brands and models. Be sure to check the best LED TV to ensure you make the right buying choice.

How to choose a Processor

Intel or AMD?
This question is vital when you're upgrading, because AMD's and Intel's CPUs won't work in the other standard's motherboards, but it's relatively inconsequential when you're building a system for the first time. Though certain AMD and Intel CPUs do certain things better than others, those differences seldom matter much in terms of ordinary, everyday computing. So don't worry that you'll be cutting yourself off from certain tasks or aspirations if you choose one over the other. But one aspect of this choice is related to the previous issue: Every CPU in AMD's consumer catalog is available for under $225, while the most expensive Intel chip runs $999. Does Intel deliver oomph to match the money? In most cases, yes—but you won't necessarily be able to take advantage of it in every situation.

Number of Cores
It wasn't that long ago that the number of cores was an unheard-of attribute about processors—now, it's the one you'll want to focus on most. For all intents and purposes, every CPU these days feature from two to six processing cores, which all work together to crunch data and thus save you time. Not every software program supports this capability, and not all the ones that do support it equally. But software for particularly intensive tasks like photo and video editing will really benefit from a CPU with more cores. Of course, the more cores a processor has within the AMD and Intel families, the more it's going to cost (AMD's most expensive six-core CPU costs less hundreds than Intel's cheapest, for example), but if you're into heavy-duty computing you'll probably find the investment worthwhile. It's not impossible to find CPUs out there that have only one processing core, but on the off chance you do we'd recommend avoiding them. Sure, you'll save a ton of money. But even dual-core CPUs are so ubiquitous and inexpensive now that it's smarter to go with two or more cores than it is to select just a single-core chip.

In general, a multiple core processor is a better choice but that does not mean it is better for all conditions.
differences between the dual and quad core products, for example, Intel may have the quad core processor with a base clock speed be 3.0GHz but when only a single processor core is in use at full load, that processor core will be boosted up to 3.4GHz. This would then make the quad core processor just three percent slower than a dual core processor that runs at 3.5GHz.  Thus, if you have a program that is only single threaded, the dual core processor is actually better. Then again, if you have something that can use all four processors such as video transcoding, then the quad core processor will actually be about seventy percent faster than that dual core processor.

Xbox One vs PS4

If you want to play video games. You should probably get a video game system. But, many gamers now confusing with question "which console should I buy?

this time, I want to compare Xbox One and PS4.

Since they launched last year, Sony has taken an early lead with the PS4 outselling the Xbox One by around 50 per cent. However, there's a good argument that a lot of that has to do with the Xbox One's high launch price, because it shipped with Kinect. When the Xbox One was launched it was  £80 more expensive than the PS4, due to the fact you were forced to purchase the Kinect pre-packaged with it. However, now, Microsoft introduced a Kinect-free Xbox One option for the same price as the PS4 - £349.99. This help boost sales and made it a much more viable choice for those who couldn’t afford to spend over £400 on a new console

One of the main reason core gamers have chosen to favour the PS4 over the Xbox One is its categorically better graphics hardware. AT many games, the PS4 renders at a slightly higher resolution than the Xbox One. 

PS4 has a distinct advantage with faster 8GB GDDR5 memory, while Xbox One went with the slower bandwidth of the 8GB DDR3 variety.

Neither system allocates all of that RAM to game developers - some is reserved to run their operating systems.

PS4 reserves up to 3.5GB for its operating system, leaving developers with 4.5GB, according to documentation. They can sometimes access an extra 1GB of "flexible" memory when it's available, but that's not guaranteed.

Xbox One's "guaranteed memory" amounts to a slightly higher 5GB for developers, as Microsoft's multi-layered operating system takes up a steady 3GB. It eeks out a 0.5GB win with more developer-accessible memory than PS4, unless you factor in Sony's 1GB of "flexible" memory at times. Then it's 0.5GB less.

There are two main changes. The Xbox One pad has rumble motors built into the triggers to give you feedback when, for example, shooting guns. Microsoft has also made huge improvement to the D-pad. The mushy Xbox 360 D-pad has been switched for one that's much more clicky and responsive. It'll work wonders on Street Fighter-style fighting games.

Sony has also massively improved the analogue sticks in the DualShock 4. Where the DualShock 3 wasn't really much cop for first-person shooters, the new pad is great for almost all types of console games. There's also a new touch pad on the front, between the sticks and the main buttons, and a Share button to make uploading your gameplay videos easy.

for more details, we can know more about the PS4 and Xbox one from the following review:

What is Netiquette?

Nowadays, a lot of people feel anoyed when using internet  because some people are irresponsible and do not follow the etiquette on the internet. this etiquette on the internet called netiquette. Good netiquette involves respecting others' privacy and not do anything online that will annoy or frustrate other people. We need Netiquette because this will be our guide while using Internet facilities such as individual Web sites, emails, newsgroups, message boards, chat rooms or Web communities. We must also follow this for us to be disciplined and for us to be a better persons. When we follow netiquette, we respect other people. When we follow netiquette and respect other people, people will respect us too. When you encounter a newbie (someone new to the Internet) you do not want him/her to venture into cyberspace until he/she are already familiar with the acceptable rules of Internet behavior. Help him/her and with a little practice he/she can become a responsible Netizen(a user of the Internet, especially a habitual or avid one).

     Example of good netiquette :

1.  Include context. When commenting on a message thread it is good netiquette to include a relevant quote from the original message to give context to your comment.
2.  Check, then click. Before you post a comment, double check that you are saying exactly what you want to say. One small error can completely change the meaning of your message, so read and read again before sending.We are only human. Remember that an actual person with real feelings, beliefs, imperfections and emotions is behind every message, email or comment. It's sometimes easy to get carried away and write something that you would not dream of saying to someone's face.
3. Do you get it? Jokes, dark humour and sarcasm are often difficult to convey over the internet. So to avoid potential misunderstandings always indicate the humourous nature of your comment. You could do this by using emoticons, putting “lol” (laugh out loud) at the end of the message or by starting with a phrase like, “On a lighter note...”
4. Newbies. We were all once new to emails, messaging and forum posts, so always try and help someone new who is making mistakes.
5.  Be yourself. If you want to get the most out of communicating online, be yourself. Making up false profiles and alter egos will only discourage people from talking openly with you and taking you seriously. Remember that most trolls and cyberbullies use false profiles, so be careful not to be taken as one.
6.  Express yourself. Don't be afraid to express yourself openly and honestly. Netiquette is not about restricting expression but about making it easier for people to understand.
7.  Allow others to express themselves too. Remember that everybody has an opinion, so allow them to express it. You may have to agree to disagree on many issues, but just make your point and move on. Don’t let a simple difference of opinion escalate into an argument.
8. Don’t SHOUT. Avoid writing whole words or sentences in capital letters. This is the equivalent of someone SCREAMING IN YOUR EAR!
9.  Respect people’s privacy. Don't pass on another person’s private information or photos unless you have their permission. Not only is this bad netiquette but you may also be accused of cyberbullying or online harassment.
10. Avoid conflict. Trading insults and abuse – also known as ‘flaming’ – is not good netiquette. It is pointless and negative and could get you banned from the site. Avoid being drawn into fights and never post abuse on someone’s message board.

After we all know what is netiquette and example of good netiquette, lets follow the netiquette and respect other people, so people can respect us too. If we dont do this, people will not respect us and do not angry at them if they do something bad to you too. when everyone follow the netiquette, we all can enjoy the internet conveniently.
