We are in a world that needs internet to survive. Without the use of the internet, a lot of business would just crumble down and a lot of people would be desperate just for a little bit of their daily dosage of social media or any other thing they use the internet for. But when it comes to 4G technology, it’s time for people to make a decision between two of the main providers: WiMAX and LTE.

Are They Similar?

Before going into the actual differences, we can see that there are similarities between both of these service providers. To start it off, they are both IP technologies, and they both support advanced multiple input and multiple output antenna technology (MIMO). So as we can see, they aren’t all that different.

Bandwidth Channels

Or are they? If we decided to look into the differences between them we can see that LTE uses different bandwidth channels that range from 1.4 MHz to 100 MHz. As opposed, WiMAX uses bandwidth channels of only up to 40 MHz, which as you can see will make an notable difference. On top of that, LTE uses different modulations for uplink and downlink, as opposed to WiMAX which has the same modulation for them both.

Speeds

Plus, if you’re going to do things fast (and possibly break them), you are also going to be using LTE rather than WiMAX because at the top speeds that these can handle are very different from one another. While LTE can handle speeds of up to 450 km per hour (280 miles per hour), WiMAX can only handle speeds of 120 km per hour (75 miles per hour).

Network Roaming

While the LTE network enables the coexistence with systems like 2G and 3G, as well as roaming between these systems, the WiMAX network doesn’t support these other systems and doesn’t allow roaming nor the coexistence between them. But then again, the costs for building a WiMAX network are lower than the costs of building a LTE network.

As we can see, LTE is compatible with a lot more technologies from the old days (this is important because, unfortunately, we can’t just get something whenever it comes out – we’re not rich) and on top of that, it enables a lot greater speed for mobile users. These are all significant advantages and if you can afford LTE you should always choose it over WiMAX since the advantages speak for themselves.

Of course, if you are going for 4G on a lower price, than the obvious choice you are going to take is WiMAX, but you will need to remember that you are doing it just to save a little bit of money. While doing so, you are however going to lose quality on the service provided.

Any real photographer needs to have a really good camera to keep up with him. After all, those amazing pictures we see pretty much everywhere weren’t captured with a smartphone, were they? Cameras, allied to amazing photographers, have the power to capture sensations, emotions and spirits all at once – and that is one of the most amazing arts out there.

What Makes The T3i and T4i Different?

There are two mainstream cameras around the corner that need to be looked into: the T3i and the T4i. When photographers looked at the differences between the T2i and the T3i they realized they weren’t significant, but that is not the case then it comes to the differences between T3i and T4i.

To start it all off, the T4i brings in a new technological advancement we could see on other platforms already: the touch screen. One of the most frustrating parts of having a decent camera was the navigation though dozens of pages of options and settings and through dozens of buttons and arrows that you needed to identify first. Now, the touch screen technology is here to make it all worthwhile: just ask anyone who has a smartphone.

But we’re not here to talk about how well the camera does when your pushing its buttons, we’re here to talk about how well the camera does when you are using it for its purpose. The technological advances on the new T4i model now made it even better when it comes to the auto-focus system.

Usually, cameras only had sensors that were able to focus either horizontally or vertically, so a lot of objects being photographed were getting “damaged” in the quality of the images that were coming out – simply because the sensors couldn’t handle it. With the new technological advancements, now sensors can focus both horizontally and vertically, which means that the new T4i is going to perform better than the T3i, without a doubt.

When it comes to the processor, and how well the camera can process image data, we can also see an advantage in having the T4i by your side instead of the T3i. The T4i has now a new Digic-5 processor, which is actually six times faster than the old processor found on the T3i, the Digic-4 processor. This is an improvement so big, that now the T4i can reach a top burst speed of five frames per second, while the T3i couldn’t even reach the four frames per second, even on its best days.

Due to all of these differences, we consider the T3i model to be a weaker, outdated one regarding the T4i model. As you can see, technological advancements have made the difference in these two cameras and as such, if possible, you should always go for the T3i.

The Apple iPad has become a common electronic accessory and it comes in a variety of different sizes. While it can be tough for a person to decide between the 16 GB iPad and the 32 GB iPad, this decision should be made based on the usage needs of the consumer. The two devices may seem similar on paper, but there are a key differences that a consumer should be aware of before making a purchase.

What Are the Differences?

The 16 GB iPad is perfect for the person who does not need a great deal of storage space. If you are someone who simply uses their tablet to browse the Internet or check your e-mails each day, then the 16 GB iPad will suit you quite nicely. But a person who has greater storage demands may want to look into purchasing the 32 GB iPad.

Which One is Right For You?

A user who uses their tablet to play games, download all of the newest apps and watch feature films should choose the 32 GB iPad, as it provides the additional storage space needed for these activities. Another key difference between the 16 GB iPad and the 32 GB iPad is the pricing structure.

Cost Differential

For every additional gigabyte, Apple charges the consumer extra. The difference between the 16 GB and 32 GB iPad is roughly $100, which could be the deciding factor for many consumers. There are ways for the user to add extra storage without purchasing an iPad with more storage capacity, but even iCloud storage comes with a modest fee.

Media Use

The more streaming that you do, the more storage you need. Even those who do not stream full length movies on their iPad should think twice about purchasing the 16 GB if they plan on streaming YouTube videos and music files on their tablet. An iPad is capable of compressing these files, but only up to roughly 15 percent.

As you can imagine, this will eat up any extra space you have very quickly. That’s why the main difference between the two iPad is the storage size. You will need to evaluate your usage needs and decide whether the additional space is truly important to you. The more games, apps, television shows and movies that you download and stream, the less space you are going to have for other forms of storage, so tread wisely.

There are options available to the consumer to increase storage space, but these typically involve the purchase of an eternal storage unit or the use of iCloud storage. While there are very few major differences between the 16 GB iPad and the 32 GB iPad, a consumer must be well aware of what they are trying to accomplish before making a decision. The casual browser typically favors the 16 GB, while those who require more from their tablet will opt for the 32 GB.

Screen printing or serigraphy is a printing process that was invented in China over two thousand years ago. As its name implies screen printing uses screens to create different layers of color on a material to make the required design. The process uses a perforated screen to transfer ink onto the material to be printed on (called the substrate), while also preventing the ink from getting on parts of the substrate with a non-permeable material (a stencil) attached to the screen. The ink is pushed through tiny holes in the mesh onto the material as the printing machine momentarily presses the screen against the material. This process is repeated using different inks and stencils until the desired pattern is achieved.

Digital printing on the other hand, is a computer based printing method where a digital image is printed directly onto the substrate. It is sometimes called ‘direct imaging.’ The image to be designed on the material is first created in a computer as an artwork, and then it is transferred directly onto the material in much the same way as we print paper documents on a desktop computer/printer system. Digital printing is a fairly new development in the art of printing.

So which is better? There is no definite answer to that question because each method of printing has its pros and cons. To determine which method is preferable one would have to take into consideration the specifics of the particular design. Factors to consider include the quality of the final product, material to be printed on, size of the order, the project budget and amount of time available.

Screen Printing

Pros of Screen Printing
1. Ideal for large orders because costs reduce with quantity.
2. Produces vibrant colors due to the thickness of ink applied.
3. Longer lasting and more durable.
4. Good for large size prints.
5. Versatile: Prints on wide variety of materials and shapes.

Cons of Screen Printing
1 Requires a lot of set-up time: screen, stencil and ink preparation.
2. Minimum order required.
3. The end product feels thick.
4. Not good for photos or high resolution images.
5. Not always clean.

Digital Printing

Pros of Digital Printing
1. Great for small orders; can print only one copy.
2. Is good for photos; it has excellent resolution.
3. Great for complex designs with minute details.
4. The finish is thin and cannot be felt.
5. The final product is very clean.

Cons of Digital Printing
1. Cost does not reduce with quantity.
2. The range of colors is limited by the printer.
3. Cannot print white ink.
4. Print area limited by printer size.
5. Ink is expensive.
6. Prints mostly on fabric and paper.
7. Print time is longer.

So, screen printing or digital printing, which is better? The answer is determined by your specific project and circumstances. Have fun printing.

If you’re like me, you probably just think that printing is printing, and that there’s no real difference between offset and digital printing right? Well, as it turns out, there is really a difference between them and we are going to look at the differences between these two printing methods in this article, so that you can make the best possible decision regarding these two when you get to your next print project.

Understanding Offset Printing

Simply put, offset printing is the best solution whenever you are in the need for large quantities due to its technology. It uses plates that are usually made out of aluminum that transfer the image onto a rubber “blanket” which will, in turn, roll the image into the paper sheet you use. The name “offset” was given to it because the ink is not directly transferred into the paper, it has a stage where it goes through the “blanket”. It provides proper color reproduction and a clean looking printing, just like the professionals do it. It is, of course, the best choice when it comes to large amounts.

Digital Printing

Digital printing, on the other hand doesn’t use plats just like offset printing does. It uses a variety of options such as toner and uses liquid ink. Digital printing only rises above offset printing whenever you are in the need for a low amount of printing. The use of variable data printing is only possible in digital printing as well, since offset printing cannot accommodate that. Variable data mean that each piece is a little different than the other, without damaging the whole collection as a whole.

What Are the Benefits

The advantages of using digital printing include the costs (the costs are lower on the shorter runs) and you are only going to be printing small amounts so convenience is also a factor. You are going to print what you need whenever you need it, in the amounts you need.

As referred above, you also have the variable data capability so you can make personalized pieces to each one of your employees without having to waste a of money.(assuming you want to give your employees some flowers that is). Finally, digital printing has improved in the last few years due to technological advancements and as such, the quality makes it acceptable for a lot of users worldwide.

On the other hand, offset printing has a lot of cost advantages when it comes to printing in large amounts and the more you print, the cheaper it is going to be for you per piece. There is also the possibility of using special custom inks that you wouldn’t be able to use in digital printing due the type of printing and its own nature. Offset printing is the way to go is you are looking into large amounts.

If you are a fan of lasers and all of that, or if you need to get some treatment with a laser or an IPL, you might get confused as to what they are, since they look like the same thing at first. After all, IPL means Intense Pulsed Light, which, to me, sounds like a laser. That is, at least, what most people end up thinking – but they are wrong.

What Is Their Similarity?

The big similarity between IPL and laser is that they are both used for permanent hair removal, and they both use light while doing so – that is about it. Their applications can be incredible different due to the fact that people have different skin colors and different resistance to the light, as such some situations call for an IPL while others call for laser.

They both involved the production of energy in the form of a spectrum of light that is then absorbed by the pigments of the hair. This is the big purpose of both of them, but to understand them properly, we need to go a little bit into the differences between them.

Laser Machines

Laser machines are the well-known kind of hair removal machines and they are pretty simple to understand. What they do is that they generate a wavelength of light that concentrates on target in order to target the melanin that is present in the hair follicle.

We can distinguish IPL machines from laser machines because these form a broad spectrum of wavelengths while the laser machines form one single wavelength that focuses on target. This means that usually, people think that IPL isn0t as effective as laser due to the concentration the laser wavelength has on a single hair follicle. This isn’t exactly the case, since the need for IPL only applies to people with darker skin or darker hair follicles.

People with lighter skin and lighter hair follicles have no need for an IPL, or no need for a laser precisely. In fact, either one of them works perfectly fine for people with light skin and hair follicles, but people with darker skin or hair follicles will probably have the need to use laser instead of IPL due to the broad spectrum of wavelengths produced. IPL can cause burns on darker skin types while the laser, since it is focused, is also adjustable and a lot easier to control.

IPL

IPL is, however, less efficient in the treatment of hair reduction due to the fact that it is not reinforcing and coherent (as opposed to the focused wavelength of the laser) but it is sometimes a necessity because IPL has a cheaper price as opposed to laser treatments.. Nevertheless, it is quick to spread out, so the affected area is going to be larger.

Zillions of emails are sent globally each year. The email has become a very important means of communication since the 1970s when it was first introduced. It is increasingly becoming more popular than the traditional mail which involves post offices, postmen and mailboxes.

Email stands for electronic mail. It is a very fast and convenient means of sending and receiving messages. The recipient usually receives the email immediately the sender sends it. A byline for email would probably be ‘mail at the speed of light.’

The Workings of Email

In many ways, the email is just like the traditional mail except for its speed and transport means. Using the traditional mail, a sender writes the recipient’s address on the outside of the message and posts the message by sliding through a postal slot located anywhere nearby, or a postal drop box along the road. A postman collects the message from the drop box and takes it to the post office. At the post office, the message along with other messages, is sorted and arranged per destination and then taken to the nearest post office to the recipient’s address. There, at the second post office, the postman takes the message and slots it into the recipient’s post office box which is sometimes located at the post office or at the individual’s home or office. The recipient obtains the message by accessing the mailbox.

Email Protocols

In the email system, the server operates like the post office while the post office box may be likened to the user’s device such as computer or smart phone. Two major email methods of delivery (protocols) exist. They are POP3 (Post Office Protocol 3) and IMAP (Internet Message Access Protocol).

POP3

POP3 is very similar to the traditional mail system in that once the original mail leaves the post office (read server) and enters the recipient’s mailbox (read inbox), there is no copy of the mail at the post office (server).

IMAP

IMAP however, presents a very interesting phenomenon. Unlike the serial delivery method of the traditional mail and POP3, IMAP somehow copies all the clients/devices attached to an email address. Using the traditional mail, the representation of this method would be if the postman decides to make a copy of the mail that would be retained at the post office and also makes a copy of the mail for wherever the recipient goes such that a copy of the message would be sent to the individual’s office mailbox, home mailbox and any other forwarding address the individual leaves at the post office.

And just like in the traditional mail that the recipient accesses the mail by using a key to open the mailbox, the recipient also uses a key (password) to access his/her inbox in the email.

While IMAP may be desirable because of accessibility of messages whenever and wherever, security may be an important limitation. However, POP3 presents a likely one time read of messages. This reduces the security risk but at the same time, restricts accessibility. Either way, use of one over the other may be a matter of preference rather than benefits or limitations.

When it comes to fluorescent light bulbs there are two main types you will be able to see pretty much everywhere: T8 and T12. Obviously, they are different, but most people think that their differences are just in the name – but that is definitely not the case. Each one of them has its own advantages and disadvantages, so it is worth looking into each one of them in order to know the difference between them and make the correct decision.

What is Their Size Difference?

When it comes down to T8 and T12, size does really matter. One of the primary differences between these two is the difference in size that the bulbs have, and the difference their bases have. In length, they are incredibly similar, but the numbers after the “T” are referring to the diameter of the bulb. This means that the T8 has a diameter of eight eights of one inch, and the T12 has a diameter of twelve eights of one inch.

Typically, the efficiency of a lamp can be determined by its size, and the smaller the lamp, the bigger the efficiency. This means that out of these two, the T8 is more efficient, but the T12 is bigger. Depending on the usage you are going to give these fluorescent bulbs, one might be more appropriate than the other.

How Does Energy Usage Differ?

When we’re talking about light bulbs, we need to look at the energy usage as well. Not only does a better energy usage provide the user with a better overall experience due to a significant cost control effectiveness, but also due to the fact that lower energy usage is good for the environment.

And when it comes to energy usage, the T8 bulb is 32 watts, while the T12 bulb is 40 watts. This clearly means that the T8 is a more efficient light bulb to use and due to a federal act, a lot of buildings have to use the T8 bulb instead of the T12 preferably due to energetic efficiency.

What is Their Light Output?

This is the key question that you need to ask yourself when you are buying a light bulb – does it give me enough light? We’re here to compare the T8 and the T12 fluorescent light bulbs and the truth is that, between these two, there is a very small difference. So small, that the human eye isn’t able to detect it at all.

The T8 light bulb puts out a little bit more light than the T12 light bulb, but once again, the difference is incredibly small. Light output is measured in lumens, and the T8 bulb producers approximately 2600 lumens, while the T12 bulb produces approximately 2520 lumens. You might not know the value of a lumen, but by the number reaching 4 digits and the difference being only of 80 lumens, you can clearly tell that the light output isn’t too different.

There is, however, another faction to consider when it comes to light output. Over time, and just like every other material object we know in this world, light bulbs begin to lose the intensity and brightness of the light they put out – it is just natural. After around 7,000 hours of usage, the bulbs tend to decrease. The T12 bulb tends to decrease by around 20 percent, while the T8 bulb only decreases by 10 percent – half of the decrease the T12 bulbs have. This means that, over time, the T8 fluorescent light bulb is a better choice when it comes to light output.

What is Their Longevity?

We’ve seen that the light output of the bulbs decreases over time, and that takes us to the topic of longevity – how long do the bulbs last? After all, you won’t want to have to replace them too soon, since it is a painful task to have to go the store get a new bulb and replace it, especially for the modern person who is always busy.

Turns out, the longevity of the bulb is directly related to its light output decrease. The bulbs tend to start decreasing their light output after around 7,000 hours of usage and even though that sounds like a lot, it is not an eternity (unfortunately). After that period of time, they start to lose quality, but most people only replace their light bulbs when they really stop working.

The decrease that the bulbs have in brightness is so low, however, that it is usually not visible to the naked eye at first and people usually only notice that the bulb had been losing properties after they replace it with a new one. Either way, the recommendations that manufacturers put out there is that the bulbs should be replaced every 6 to 12 months in order to maintain the quality.

If you’re wondering about the amount of time required before replacing a bulb, let’s put it into perspective: a bulb that keeps on running for around 10 hours a day will only need to be replaced after around two years and unless you sleep with your lights on, yours will last a lot longer.

To sum it all up, the T8 light bulb is going to last you a little while longer than the T12 light bulbs since they lose properties at half the rate the others do, but that isn’t a big factor according to what manufacturers recommend, since they both start losing qualities at the same time – the time that manufacturers tell you to replace the bulbs in order to get better quality.

You want a new printer but are not sure about whether to get an inkjet or laser printer because you don’t the difference. Businesses are people are normally faced with this dilemma when buying a printer. Many buyers work under minimal budget obligations and it is quite normal to consider initial purchasing costs and space limitations. However, it is important to consider the long-term operational costs associated with each printer.

The differences between inkjet and laser printers is normally categorized into segments like speed, cost, maintenance, networking facilities and space. It is also equally important to understand the different technologies used in the manufacture of ink cartridges and laser toners as they influence the cost.

If you don’t the difference between inkjet and laser printers, not to worry! The process of buying a printer for your home or business shouldn’t be a heartache. This article will explain your options as well as how they will affect your pocket both in the short-term and long-term.

Laser Printers

Laser printers utilize heat to combine powdered ink on to paper. It doesn’t bleed on the paper, and for that produces sharp and very crisp results. They are the best printers for printing lengthy documents with lots of words. They are also very fast and will bring out very clear text. They are also good for image printing, but not highly recommended for high quality or commercial printing.

Major points include:
1. Speed
2. Heat
3. Very clear documents
4. Ideal for text

You can also check for sites like Amazon for good customer reviews and ratings.

Inkjet Printers

Inkjet printers on the other hand spray small, microscopic ink dots on the paper. The ink is absorbed into the paper and slightly bleeds. You can get special paper that doesn’t bleed as normal paper. An inkjet printer can be used to print word documents, but they won’t be as sharp and crisp because of the bleeding. Bleeding is actually useful for images because this is where gradients really work.

They are a good choice of you are looking to print photos and images the most. Majority of photo printers are actually inkjets with a couple of additional features.

Major points include:
1. Ink bleeding which is bad for text but great for photos.
2. Microscopic dots.
3. Ideal for photos.

You can also check for sites like Amazon for good customer reviews and ratings.

Cost of Ownership

Inkjet printers tend to be slightly cheaper than laser printers. The same applies for the printers themselves and the toner/ink. However, inkjet printers cost more per page because they are less efficient. For this reason, inkjet cartridges will be cheaper, although you’ll need to buy them on a regular basis.

1. An inkjet printer is slightly cheaper.
2, Inkjet cartridges are cheaper.
3. A laser printer is more efficient.
4. A laser printer cartridge will last longer, meaning you’ll visit the store less often.

Black & White Vs Color

You can buy black and white or color versions of inkjet printers and laser printers. Keep in mind that laser printers cost more, so color laser printers will even be more expensive. The upside is that you’ll refill your laser way less frequently.

How About All In One Printers?

When you buy all in one printers, you’ll still need to choose between inkjet and laser. They both use different technologies. Inkjet and laser all in one printers typically offer faxing, scanning, copying and printing features.

Can The Printers Connect To My Home Wi-Fi?

Both these printers have Wi-Fi capabilities, but it’s not all of them with such capabilities. You’ll need to pay special and detailed attention each time you purchase a printer to make sure that it will be able to connect to your home network, if you want that.

Difference in Printing Speeds Between Inkjet and Laser Printers

While laser printers may lose out on their counterparts in terms of price, they are however much further ahead when it comes to printing speed. Users in need of large printing volumes prefer to purchase laser printers. Laser printers to be better suited to simple office work than inkjets. The cheaper laser printer has the ability to print about 10 to 15 pages a minute.

Inkjets are normally classified on their speed of quick printing or draft mode, which is ideally suited for proofreading. An HP Business Inkjet 2800dtn, a fast printing color printer with the ability to print at speeds of 21 pages per minute black, and 15 pages per minute, color mode. The speed does however drop significantly when printing top quality black text or printing quality photos.

Which Printer Should You Purchase For Your Home Network?

Both these printers print text and photos. However, you need to think about what’s more important to you, or what you’ll be using the printer for.

If you intend on printing text documents, then you should go for a laser printer. If you are however interested in printing high quality photos, then you should go for an inkjet printer.

If you are on a minimal budget, you may want to consider an inkjet printer as this may be your best option. If you don’t mind spending a bit more, then a laser printer will prove to be more expensive initially, but it will save you lots of money in the short and long-term future.

After everything has been said and done, the rest is up to you on which printer you will buy. Always go for one that will suit your needs and requirements.
