A few years ago no one really cared about the quality of the image we were getting on our screens, we were all just incredibly thankful that we actually had a screen to look at and that it was even possible to broadcast images like that – it was an incredible technology and at the beginning, we didn’t even have colors on our images.

Evolution of Video Quality

Thanks have evolved so much that we now have incredibly high quality videos out there and we keep on taking steps forward. So much so that some people now believe that we went too far with the quality of our videos and that we are now beating the limits of the human eye. This means that even though we have incredibly amazing image quality on our TV’s, we won’t be able to tell because our eyes have their limits.

This is, of course, what some people believe, while other actually believe that we haven’t peaked at all and that we still haven’t reached a resolution so good our eyes can’t see it. This debate sparked due to the coming on a new technology, the Ultra HD. Ultra HD actually went beyond the maximum capacity of HD which was 1080p, and now the 4K and the 8K are out there.

What Are the Differences Between 1080P and 4K?

In this article we are looking at the differences between the top of Full HD (1080p) and the bottom of Ultra HD (4K) so that we can understand whether or not the real difference can be felt, and if a UHD TV is actually worth it by now.

When the first UHD TV’s were launched into the market, both Sony and LG placed them for sale at around $ 30,000. This was clearly a high-end market that only incredibly rich people were going to exploit, but not to wonder. 4K TV’s were actually displaying an image four times better than the “old” 1080p TV’s. This incredible price didn’t last too long and, soon enough, the price of a 4K TV is now at $ 1,000, but the best ones when we look at price and quality and compare them, are sitting at around $ 3,000.

4K was originally designed to improve the 3D experience in the home of every person who would own such a TV. 3D renders two images and mixes their light together to create the 3D effect, but this lowers the quality of the image in half. As such, 4K would still render a 3D experience with better image quality than 1080p.

Is the Price Right?

Right now, we believe that the incredibly huge price that 4K TV’s have isn’t really worth the amount of money, not because of the lack of quality – the quality in them is amazing. But rather due to the lack of content available in 4K. It is an incredibly recent technology and, as such, there is still not a lot of content out there. Companies such as YouTube and Netflix are creating content on this amazing quality but it is still going to take its time. Soon enough, the price of these TV’s is going to go down, and the amount of content available is going to come up, so later on they will be well worth it.

People say that a 4K TV is worthless because your eyes can’t perceive the difference unless you are glued to the TV, but tests suggest otherwise. According to some TV experts, as long as you have a big TV from 55 inches and above, you are going to be able to see the difference between 1080p and 4K when it comes to fine detail. This sets a new trend in the world of televisions, since they are going to get bigger and bigger.

Smaller televisions are actually not going to have a difference in the quality between 1080p and 4K due to the fact that their pixels are all mashed up together and, as such, you will never be able to tell the difference between one and the other on smaller televisions. When it comes to quality, the bigger the better.

The distance a person needs to be at from a 4K TV to see the best possible image is now also relevant. With 1080p TV’s you just sat wherever you were comfortable and watched the TV, the quality was still going to be the same, but now things have changed. From a 65 inch TV, the best possible distance is around 1,5m in order for you to get the best possible quality out of your expensive TV. The larger thee TV, the bigger the distance, so it is still a technology for the rich, since people with a small house and a small TV are going to have a bad time operating this way.

Soon enough, it is expected that 1080p TV’s are going to be left alone in their own corner just like any old technology, and that 4K TV’s start hitting the market big time. The technology is still fairly recent and as such, the amount of content available at this quality is still going to be increasing. It is also possible to improve the old classics of the cinema so that they resemble this quality as well, meaning that the classics are going to get better and better with the passage of time.

While HDMI connectivity was enough for 1080p resolution screens, now there is a new type of HDMI coming in for the 4K resolution screens: HDMI 2.0.

Apple and Samsung are constantly toe to toe when it comes to the competition on the area of mobile technology. One year Apple gets the lead and the next year Samsung gets the lead. Two of the major competitors in this race for the top spot are the Samsung Galaxy S4 and the iPhone 5.

Competition in the Marketplace

These two competitors are both incredibly popular and they are clearly at the top of the line when it comes to technology. They are, however, incredibly different and at the bottom line they are both amazing devices. In the end, it comes down to preference and not to quality of the device itself.

On one side we have the Android operative system, brought to us by Google. We are, of course, talking about Samsung Galaxy S4. The good part about Galaxy S4 is that it is available in pretty much every store you can find smartphones in, and on top of that it is extremely well rounded. There isn’t really something that you can point out and say that is terrible about the phone.

The Galaxy

The only thing one can point out about Galaxy S4 that is indeed behind the rest of the quality on the phone is the design itself and the display of some of the settings. It can get a little confusing to some users and that is just downright disappointing. The phone itself is fairly simple to use, but some things are hard to understand.

The iPhone

On the other hand we have iPhone 5. Apple introduced it into the market in 2013 and ever since then it has been a smashing hit among mobile technology lovers. The first thing done to it is that the processor was improved and the operative system was there to back it up. With iOS7, the iPhone 5 clearly carved its path in the market with excellency.

What Makes Each Better

The good thing about the iPhone 5 is that it was a great improvement when compared to the iPhone 4. It is twice as fast as the old model and on top of that the camera saw some significant improvements. Now, it is possible to shoot a 120fps slow motion video, which is just sweet.

But the iPhone 5 has also got some flaws. A lot of people find the design of the phone and its aesthetical display a little bit unfinished. Some people find the 4-inch screen too small, some people feel that the phone could be a lot better.

Bottom line, these are two amazing phones and they are the top of the line. They might have some flaws but if you think about it, these flaws are nothing when you see the advantages that they carry over the competition.

Back in the day, phones were usually not too flashy, they were just good enough for us to make a phone call, send one or two text messages and that would be it. Nowadays, we have evolved so much that cell phones are now incredibly advanced, they are extremely advanced computers and keep on evolving.

Samsung

Samsung is a company that keeps on making smartphones for pretty much everyone. They aim for every demographic with phones that pretty much cover every possible necessity that a person can have. In this article, we are looking at the Samsung Galaxy S4 Active and the Samsung Galaxy S4.

Galaxy S4

The Samsung Galaxy S4 was pretty much one of the strongest and most advanced devices released in 2013. The smartphone could do a lot more than what computers could do just a few years ago, but then Samsung Galaxy S4 Active was released and it was even better.

Galaxy S4 Active

Samsung Galaxy S4 Active is just a little bit taller and a little bit thicker when compared to Samsung Galaxy S4 itself, but this doesn’t matter a lot since the difference is minimal. It also weights a little bit more, but nothing that is going to make your hand feel tired after using it a lot.

Screen and Hardware

Both of these phones have an incredible 1080p 5-inch screen that works wonders. If you want to see a video in high quality and see some great eye candy, both these phones are going to deliver it properly, even though Samsung Galaxy S4 Active has a little bit better of a Pixel per Inch density, which makes it better, but the difference is just microscopic.

Both these devices have a 2 GB RAM memory in them, and both of these have the same type of wireless technology, so there is no real difference in these two topics. There is a difference, however, when it comes to the camera that is on the smartphones. While Samsung Galaxy S4 has a 13 MP rear camera, and a 2 MP front camera, the rear camera of Samsung Galaxy S4 Active has just 8 MP, while the front camera is equal.

What Makes the Active Different?

The big thing about Samsung Galaxy S4 Active is that it is made for people that are going to be on the move and that are going to be facing harsh conditions throughout their daily lives. Samsung Galaxy S4 Active is actually waterproof and a little more resistant than the normal S4. This means that it is a niche phone: it is aimed at hikers, runners, extreme sports enthusiasts and so on. This is the major difference between these two and if you are just looking for an amazing phone, the regular Samsung Galaxy S4 is more than enough.

Whenever the Windows operative system is upgraded there is more than one version for people to purchase. Most people just go ahead and purchase the normal edition because they have no idea about the features of other editions and they know that the normal edition is exactly what was made for them.

But sometimes it might be good to get one of the other editions. They might be a little bit more expensive, but they come with perks that other editions do not come with. As such, it might be a pretty good idea to know about the difference between Windows editions, and in this article we are going to look at the Home Premium and at the Professional edition.

Basic Operating System

As the name says, the difference between Windows Home Premium and Windows Professional revolves all around the purpose of use of the machines. While Windows Home Premium is made for enthusiasts that want to get the very best out of Windows machines, Windows Professional is aimed for professionals that are going to use the machine to maximize their business.

The first difference between these two is the memory support that the machine has. For Windows 7, while Home Premium had 16 GB supported, Windows Professional had 192 GB supported. The difference is clear. Similarly, while the Home Premium edition can only support 1 CPU, Windows Professional can support 2 CPU’s.

Home Premium Edition

While the Home Premium edition can only back up the resources in it in the “old fashioned way” – through CD’s, local drives and DVD’s, the Windows Professional edition has a new perk on top of these: it can store its files in a network system, another PC on that network or even in a hard drive connected to that network. These are network-attached storage devices (NAS) and they are incredibly useful for professional looking to back up their resources.

Furthermore Windows Home Premium can only encrypt files if manual encryption is request by the user through third-party programs. Users who are going to be working on their machines at home usually don’t require this as there isn’t a lot of sensitive information in its folders that could get stolen (information placed on websites is encrypted).

Windows Professional

Windows Professional, however,, has an encrypting file system placed in it so that professionals can have their logs safe from hackers or from competitors that don’t really want to do things the correct way and that try to reach their sensitive information. As such, they have an encrypting system that comes with the operative system.

All these differences clearly point out that the names are well applied to these editions and that for the average user, there is no need to have Windows Professional. There is only the need to have Windows Home Premium,

When it comes to sending emails, distinguishing between cc and bcc is imperative. The wrong recipient format may result in particularly embarrassing situations. The difference between the two, while closely related, can be night and day. When sending emails, you may wish to send identical copies to multiple recipients. This can be particularly useful when it comes to sending out a mailing list or informing your office or team about recent changes or upcoming projects.

A Way to Communicate

Do you remember working with carbon paper to produce copies of forms? That’s what the term ‘cc’ is supposed to denote. Cc literally stands for carbon copy. Once you send out an email with multiple recipients in the cc field of your email, they’ll all receive a copy of the email. The thing to keep in mind is that all recipients of the email will be able to see who else received the email. This can be useful when you’d like to establish something of a conference chat over email.

But if you’re looking to keep the identities of your recipients secret, cc may not be for you. Still, cc can make it easier for you and other people to verify who actually got the email. Cc works best when you’re sending an email to a small, manageable group of about six people or less. Use cc for school projects, team projects, and for when you’d like to send an email to multiple friends or family members.

When to Use Bcc

Bcc works the same as cc. Every person who’s entered into the bcc field will receive a copy of the email. However, the ‘b’ in ‘bcc’ denotes that this is a “blind” copy. All recipients of the email will be unable to see who else received the email. This can be preferable for a number of reasons. For one, you may want to conceal and protect the identities of your recipients. If you have over ten recipients of one email, bcc can help ensure that your recipients aren’t dealing with a giant, overwhelming list of emails they’ll have to sort through before even being able to read the email. Bcc, in this regard, can often appear to be more professional. As such, it’s advised for anyone who’s sending out company-wide emails or otherwise needs to update a large group of people about certain events or policies.

Understanding whether to use cc or bcc is key to sending effective emails and minimizing potential confusion. Cc should be reserved for more personal emails and conversations, while bcc is key for formal, professional, and discreet communications. Make sure you understand the difference between both. Sending email copies can save time, confusion, and effort when it comes to making sure everyone’s on the same page.

When studying physics, the concepts of electricity and magnetism take on added importance, but they are also crucial to many other fields besides the world of physics, as well. They are both forces of nature that are responsible for currents and fields, but their functions are actually quite different. Read on in order to learn more about the key differences between electricity and magnetism, two forces of nature that are often confused with one another or erroneously thought to be interchangeable.

How Electricity Works?

Electricity has more to do with electronic currents and fields, while magnetism focuses more on fields and currents of a magnetic nature. Electricity is typically described as a force that occurs during the presence of electric charges. These forces take place due to shifts in electric charges.

These charges are divided into two groups, positive and negative. The charges are described according to the field that they are a part of. Electric fields and electric charges cannot exist without the presence of the other. Electric fields are produced by electrical charges and this is true whether they are in the process of moving or if they are stationery.

What About Magnetism?

Conversely, magnetism is a phenomenon that is produced as a byproduct of electricity. When electric charges begin to move, this is when magnetism takes place. But what many do not know about magnetism is that it also possesses a duality. Magnetic poles are created when electrical charges move in one direction or the other.

These charges are what is known as north poles and south poles. Whenever magnetic poles occur, they always arrive in pairs. Magnetic poles that are similar are not attracted to each other, while magnetic poles that are dissimilar are drawn to one another.

What Are Their Main Differences?

The main difference between electricity and magnetism is magnetism’s presence. Electricity can be present in a static charge or the presence of a moving charge. Meanwhile, magnetism’s presence is only felt when there are moving charges as a result of electricity. Simply put, electricity can exist without magnetism, but magnetism cannot exist without electricity.

Electric charges also differ from magnetic ones, because they can take place in monopoles. In order for there to be an electric charge, the positive and negative charges are not required to work in pairs. On the flip side of the coin, a magnetic monopole in non existent. Magnetic charges require the presence of opposing pairs in order to produce their charges, making magnetism dramatically different from electricity.

As you can see, these two seemingly similar forces of nature are actually quite different and have completely dissimilar traits and requirements. The differences between magnetism and electricity are vast, which is what makes the study of each force so interesting to many.
