Difference Between Optima Batteries

Difference Between Optima Batteries

Optima batteries are excellent for starting and powering motors of all kinds. They tend to last longer than other batteries and give you more power in a smaller box. This is due to the Sprialcell technology that is used in all of their batteries. But your Optima battery isn’t going to do anything for you unless you buy the right one. Optima batteries come in three main styles, denoted by the color of the top plate and known as Redtop, Yellowtop Bluetop batteries.

Types of Batteries

Redtop batteries are for use in most ordinary commuter vehicles. It has to be connected to an alternator in order to provide extra energy if it is needed. In addition to your standard automobiles, Redtop batteries can also be used in RVs, heavy equipment where its primary function is startup, and diesel vehicles with no aftermarket electronics.

Yellowtop batteries are designed for vehicles that have no alternators or higher than usual energy needs. Aftermarket additions are the most common reason Yellowtop batteries are needed. These additions include stereos, GPS, additional chargers, snowplows, and winches. Certain vehicles may require Yellowtop batteries even in factory condition, for example, minivans with electronically powered sliding doors. DVD players are another reason to use Yellowtop, especially if you will be watching DVDs while the motor is off.

Racing vehicles also use Yellowtop batteries. This is because they do not have generators or alternators, so all of the electricity used by the vehicle has to come from the battery. Vehicles modified for drag racing need Yellowtop as well. If you are driving a hybrid vehicle or an electric car, once again you will need a Yellowtop battery.

The final type of Optima battery is Bluetop. The Bluetop battery was originally designed for marine applications, which explains the color choice. It was made in two different styles, a starting battery which has a dark gray case and a dual purpose battery which has a light gray case.

Chosing the Right Battery

The starting battery should only be used when no deep cycling is needed. For marine use, this would be ideal for any boat in which the battery’s only job is to get the motor running. It can also be used in RVs under the same conditions.

If your boat has heavy electrical accessories or a trolling motor, then you need the light gray Bluetop battery which has extremely high cranking power. Again, the battery can be put in RVs if a simple starting battery is not going to provide sufficient power.

Optima batteries are very powerful and can last a long time, provided you match the right battery to the right vehicle. Make sure you understand your vehicle’s energy needs before purchasing a battery and you are sure to get the right one.

Difference Between 4GB and 250GB Xbox

Difference Between 4GB and 250GB Xbox

The Xbox 4GB Console has a built in Wi-Fi that is used for easier connection to the entertainment world on Xbox LIVE. The TV stream and HD movies can be seen in an instant. The 4GB is ready for controller-free experiences of Kinect. This console is super-quiet and sleek and also comes with a matching wireless controller.

Understanding the Different Versions

The 250GB version is one that improves on the original and has a sleeker design with better connectivity. It has a curved design which is in sleek black. This appearance is one that is considerably upgraded and is more energy efficient and is also quieter. The 250 GB makes you forget all about issues that deal with hard drive save-space. This console allows you to play all your favorite Xbox 360 and Xbox titles, you are also able to connect to the Internet as well as compete against others through a subscription to Xbox Live. You can also enjoy older titles by way of the Xbox Live Arcade.

Key Differences

The following are the differences between the Xbox 4GB console and the 250GB Xbox console:

1. The versions of the systems is a major difference between the 4GB and the 250GB systems. The 250GB allows you more space for downloading videos, movies and any other rich content as well saving the contents as compared to the 4GB console. However, to make the 4GB console save slightly more contents, you will need to buy some external hard drives to the box.

2. The 4GB has a size limitation which poses problems like the inability to install video games which require more than one disc to play, impossibility in downloading DLC content overtime , freezing of games that have been played overtime and have scratches as well as problems which happens when it comes to storing media files with time and the regular updates that are released by Microsoft to help in patching the box reducing the hard drive space available for use. These limitations do not occur in the 250GB.

3. When it comes to design, the 250GB has a slim built-in hard drive which has a smooth shiny, black finish. This has a disadvantage in that it can become dirty quickly whereas the 4GB version is a matte black case which does not easily become dirty.

4. For casual users of the Xbox live, buying the 4GB version may be a good idea the only problem that will occur will happen in case a user would like to download DLC contents or install games to the hard drive.

5. The 4GB Xbox is incompatible with some games as compared to the 250GB.

6. The 250GB has a hard drive and the 4GB has a flash memory. Flash memory may be better in some aspects than hard drives like faster read rates, low noise, low power consumption and no heat generation. However, the main disadvantage of the flash memory is its price.

Finally for the Xbox users who need a lot of storage space, the 250GB would be the best option and for those who need the Xbox just to play and do not need storage space, then the 4GB will be a better choice.

Difference Between Ultrasound Tech and Sonography

Difference Between Ultrasound Tech and Sonography

Most people don’t know the difference between an Ultrasound and a Sonogram. In fact, the vast majority of people consider them to be the same thing. While in some aspects they are similar, they are two different techniques and procedures. Due to the fact that so many people think that they are the same, it is often a confused and misinterpreted term in the medical field, both by medical professionals who lack experience and patients who are going in for testing. Here is a simple understanding of which is which and how they differ.

What is an Ultrasound?

Ultrasound is defined as vibrations that are of the same nature physically as sound vibrations, but are above the frequency which we as humans can hear. An example of an ultrasound is the application of vibrations (as defined above) to the body to project internal views (such as when a woman wants to know the sex of her baby before it is born). A sonogram is the use of ultrasound to produce an image (such as the image of the baby). In the simplest of terms, images created in a sonogram are the product of ultrasound technology. One is the product of the second, and this is the reason that any people get confused with which is which.

Most people think that ultrasound is only used to produce a sonogram of a baby in the womb. There are plenty of other tests that use sonograms and ultrasound technology. The use of ultrasound technology can also be used to give sonogram images of internal organs and the tissues in the body. While sonograms and ultrasound technology is primarily used in gynecology, it has other vital uses in the medical field.

Since sonograms also include images of the tissues and organs of the body, these two technologies are used in cardiology (studies of the heart), vascular medicine (the veins of the body), ophthalmology (studies of the eyes and sight), and even radiology (x-rays). Most of these areas of study of medicine don’t use sonograms and ultrasound technology as invasive procedures, and this relieves stress to the patients and allows for more available testing to be done.

To Sum it Up

Ultrasound is the sound pressure at a higher frequency than we can hear so that sonograms can be produced. Ultrasound is a general term of medical technology, while a sonogram is the more specific application of ultrasound technology (primarily used in the gynecological field). Ultrasounds and sonograms are generally non-invasive procedures and will not cause harm to patients, making testing more accommodating to patients and more reliable for doctors.

For more information on ultrasound technology and sonograms, consult your doctor or other medical professional.

Galaxy Admire 4G Review

Galaxy Admire 4G Review

If you’re looking over the Engadget Samsung Galaxy S3 review, you’re going to notice something very interesting. Regardless of which provider you’re dealing with, it would seem that the Samsung Galaxy S3 is an excellent phone overall.

Exploring the Engadget Samsung Galaxy S3 Review

However, as anyone who has used this phone in the past will tell you, it’s simply not enough to call the device excellent and leave the matter at that. You’re going to want to know absolutely everything there is to know about a device that has gotten a number of strong reviews, a few middle-of-the-road reviews, and a small number of extremely negative reviews. The Engadget Samsung Galaxy S3 review can give you a pretty strong indication of what you can expect.

A Look At The Samsung Galaxy S3

Engadget gives you the ability to read up on the particulars of the Samsung Galaxy S3 for each provider offering the device. Even so, if you’re looking at an overall review of the device, here are some of the facts you’re going to come across:

1. The AMOLED display for this particular device is absolutely stunning. Whether you’re simply texting a friend, watching a video on YouTube, or getting ready to watch a movie on Netflix, you’re going to get a crisp, beautifully vivid display every single time.

2. The processor for this thing is an absolute powerhouse. Android 4 technologies ensure you’re going to be able to do just about anything you need this phone to do. Surfing the internet is going to be a joy, uploading content from your phone to the internet will be a breeze, and taking advantage of the various apps that are available for the device isn’t going to be a problem in the least. It’s true that there is a ton of competition on the Android market, but if you’re someone who is obsessed with processors, then this is still worth a serious look.

3. The MicroSD slot gives you a definitive level of flexibility with the use of this device. The odds of having to ever worry about always having the storage capabilities you need to be comfortable are extremely slim.

4. The battery is pretty darn impressive. Long battery life is generally at the top of the list (or near to the top of the list) for anyone who finds themselves in the position of having to shop around for a new smartphone. On that front, regardless of which provider you’re purchasing the phone from, the Samsung Galaxy S3 is a winner. You can of course optimize your battery potential by making sure you’re not running too many apps in the background, but if you’re someone for whom that is impossible, the Galaxy S3 from Samsung seems to understand your position. Even when it’s running a few different apps at once, this device is still going to have the ability to maintain its charge for an impressively long time. Keep a wireless charger and AC charger around all the same.

It’s easy to see why the majority of the reviews for this product have been extremely encouraging. There are going to be a few more things you’ll want to keep in mind though:

1. The camera has been getting a good deal of positive attention from critics and users on Engadget and elsewhere. The reason for that is simple, and all you have to do is look through some of the sample pictures that were taken with the device. The quality of the shots is truly going to take your breath away. With considerable storage space to back you up, you’ll be able to hold on to tons and tons of photos. The videos you’re going to be able to make are going to be extremely impressive, as well.

2. Lightweight and thin, this smartphone is easy to hold, easy to carry, and quite easy to use. Even first-time smartphone users have been raving about the ease-of-use that comes with this product.

3. Is the design too safe? Engadget seems to think so. When compared with similar devices that are currently on the market right now, the consensus from this publication seems to be that Samsung made a serious mistake by sticking to something that’s been proven to work in the past. You may find as you use the phone that you disagree. However, if you’re the kind of person who craves a change of scenery, then you may want to look elsewhere.

4. Some people absolutely can’t stand the TouchWiz interface. They find that it adds a lot of unnecessary touches to something that has a lot of promising features. If you’re a newcomer to this sort of phone, then you’re going to be fine. If you’ve had mixed feelings about TouchWiz in the past, then you’ll want to move on.

In Conclusion

Is this the best device of its kind on the market? No, but it’s good.

Difference Between Lifeproof and Otterbox

Difference Between Lifeproof and Otterbox

When you’re looking for a protective case for your smartphone, two options immediately stand out. Otterbox and Lifeproof own the market for smart phone cases. When you’re looking at comparable cases from both brands, they’re pretty even on protection. Both protect your phone on drops of over 6 feet and both will keep your phone safe from water damage even if they are submersed for half an hour. So what other features come into play to make one better than the other?

Making a Choice

One of the first things to consider when choosing between these two cases is how often you pull your phone out of its protective shell. If you’re content to leave your phone in there, then this is a moot point. But if you’re constantly pulling your phone out, you might want to lean towards the Lifeproof case. Otterbox is much harder to pull apart. On the other hand, the reason Otterbox is so much harder to open is because it gives extra protection to your phone.

Otterbox does not worry about looking pretty. It is all about protecting your phone with giant fenders all over the place. This does make your smartphone pretty invulnerable, but it also makes it a lot thicker and much heavier. Lifeproof still does a pretty good job of keeping your phone safe while still holding to a reasonable size.

Another feature of the Otterbox is a built in screen protector. This thin film helps prevent scratches on your screen. It’s thin enough to keep your touch screen almost as responsive as a bare screen would be. Lifeproof does not offer any screen protection. Because the screen itself is waterproof, this does not affect that feature of the case. While this does leave you open to scratches on your screen, it also keeps you in direct contact with your phone, which means no trouble with your screen not picking up your commands.

Differences with Lifeproof

The Lifeproof case does have some extra features that help contribute to its popularity. The best of these features is its ability to act as a subwoofer. When listening to music through your iPhone’s speakers, this case will improve the bass and mid-frequency sounds.

The downside to Lifeproof is that it is limited to iPhone users. If you are looking for something to protect your Android smartphone, they have nothing for you. Otterbox does sell models that fit Android phones.

Both Lifeproof and Otterbox sell quality cases that will keep your phone safe from most accidental damage, including water submersion. If you are looking for serious protection with no frills, especially for working in construction zones and other job sites, then the Otterbox is most likely the choice for you. If you’d like the protection without a lot of extra bulk and a few extra features, then you may be further ahead with Lifeproof.

Difference Between Canon Rebel T3 and T3I

Difference Between Canon Rebel T3 and T3I

If you’ve decided to buy your first DSLR camera, chances are you don’t want to go for top of the line right off the bat. There’s a lot to be said for starting small and working your way up, or even just staying where you are. For the amateur photographer, the entry level DSLR camera is going to do everything you ever need it to.

Because you’re probably planning on keeping this camera for a long time, it’s smart to take the time to really think about what you need in a camera. The Canon T3 is their basic, entry level camera and a smart place to start on your photography hobby. If you’ve been looking at it, the T3i has probably also come to your attention. The two cameras have a lot of similarities, but they also have some significant differences.

The T3i runs about $150 more than the T3, which may lead you to jump to the conclusion that it’s a better camera. And it is, but then again it isn’t. If the T3 will fit your needs, then there’s no reason for you to shell out the extra money for features that you’re never going to use. Here’s a look at the main differences between Canon’s two basic models to help you figure out which one you need.

Megapixels

Everybody knows that more megapixels are better. So at a first glance, the T3i’s 18 megapixels give it an edge over the T3 with 12.2. But there’s an excellent chance that you have no need for 18 megapixels. Take a minute to think about what the largest print you ever get is. For most people, 8×10 is about the biggest you’ll ever go. The T3 can print at that size with no less of picture quality. So while the T3i will print bigger pictures at a higher quality than the T3, in all likelihood you’ll never actually print anything big enough for that to become an issue. Save yourself the money and stick with 12.2 megapixels.

Autofocus

In this section, we’re mostly going to talk about aperture. If that means absolutely nothing to you, then you should be good with the T3 and you can move on to the next section. If you have a lens that will fit Canon’s digital models, see what it’s maximum aperture is. For fast apertures, like f/2.8, the T3i will be able to focus much better.

Just because you have a lens with an f/2.8 aperture doesn’t mean you need the T3i, though. Think about what kind of pictures you’ll be taking. If you want to capture your kid’s big sports moments, the T3i has a more sensitive autofocus that is going to be able to keep up with action shots. Perfect for moving targets like kids and animals. If you’re planning on taking more landscape shots, however, that’s not going to be such a big issue. The T3 will have no problem keeping up.

LCD Screen

On the T3, the screen is mounted to the back of the camera and there it stays. The T3i has a vari-angle monitor that can be swung away from the camera and then rotated. For the most part, this is a luxury. It doesn’t affect your picture quality whatsoever. But it can make getting the perfect shot much more comfortable. Pictures are always more compelling when the camera and the subject are on the same level. For shots low to the ground, this means lots of squatting or just lying down. With the vari-angle monitor, you can swing the LCD screen up so that all you can see what you’re capturing while still standing up. Like I said, it’s a luxury, but one that many people consider worth the price.

Sensor

The sensor is the part of the camera that does the actual work of making a picture. The sensor collects the light that the shutter lets into the camera and turns it into a photograph. Single lens reflex problems have always had the problem of getting dust on the sensor. That dust sits there, blocking the light and affecting the final picture.

Before digital cameras, the dust would settle onto the film. That meant it might mess up one picture, but once the film advanced the dust went with it. In a digital camera, the dust just sits there for picture after picture.

It is possible to manually clean a sensor. It involves taking a few things apart, which can be done if you are very careful. Once the dust is gone and the camera is reassembled, you’re back in business, assuming that everything got put back where it was supposed to be. If you’re very comfortable with your camera, this is a viable option for you. Mostly, it’s not a good idea to mess with your sensitive electronics too much.

The T3i fixes this problem by having a self cleaning sensor. The camera uses ultrasonic vibrations any time it is turned on or off to knock any dust on the senor off. This gives it a clear advantage over the T3, which has no such feature. These blemishes aren’t going to be severe enough to ruin your picture, so this may not be the deal breaker it sounds like. But if you’re willing to pay extra for a self cleaning sensor, the T3i gives you that option.

The T3i has some extra qualities that, if you’re willing to pay for them, might make your life a little easier. On the other hand, the T3 will give you excellent picture quality for a very reasonable price. Fewer features also equals longer battery life, which can save you a lot of frustration on the family vacation.

Canon makes quality cameras. Both the T3 and the T3i are excellent entry level cameras for the amateur photographer who is just getting into DLSR. Don’t be seduced by the higher numbers of the T3i; be realistic about what features you will or won’t use. Whichever way you make up your mind, you’re getting a good camera.

Difference Between Norton 360 and Norton Internet Security

Difference Between Norton 360 and Norton Internet Security

Safeguarding your computer against outside threats and Internet viruses is extremely important to its long term health and survival. Norton provides customers with a variety of options to choose from. Two of the most popular are Norton Internet Security and Norton 360. While they are both issued by the same company, they have crucial differences that must be sorted out before making a purchase. The following is a closer examination.

What Features Changed?

Norton Internet Security improves upon Norton’s original security program by tacking on additional features such as spam protection, web browsing protection, firewalls for software and parental controls. Norton 360 offers many of the same security features as a person would get with Norton Internet Security, with backup tools and hard drive clean up capabilities added.

When it comes to keeping your computer free of viruses and spyware, both Norton Internet Security and Norton 360 has you covered. However, each of these protections has subtle difference. Antivirus software is more geared towards continuous protection of the computer over a longer period of time. Antivirus software aims to keep Trojan horses and rootkits out.

Conversely, spyware related software has more to do with eradicating all of the junk that is already residing inside of your computer and keeping it from running at its best. Otherwise, personal information about you could be collected, leading to identity theft and other major inconveniences of that nature.

Does It Get the Job Done?

It may seem like a good idea to simply install both of these programs on your PC and ensure the most protection possible. However, you must investigate your personal needs further, so that you can choose the program that works best for you. Having both programs running in concert is not good for the computer’s long term prognosis.

Since the programs do not run best alongside of one another, knowing what you need and how to obtain it is key. Norton Internet Security delivers all of the same capabilities that Norton 360 does, but with a few key differences.

Norton 360 provides extra features that Norton Internet Security does not. With Norton 360, users have increased storage and backup capabilities, which is crucial for those who store important files on their computer. No one should have to experience the frustration of losing all of their work or personal files due to a virus or worm of any sort.

Norton 360 also offers PC Tuneup, which Norton Internet Security. PC Tuneup provides an easy to use removal program so that cookies and other detritus that accumulate inside of the PC are able to be scrubbed away and ensure that your computer always runs at its best.

There is a slight difference in price between the two programs. Norton 360 is equipped with the extra features, so it costs slightly more. Customers will spend 59.99 to bring home Norton 360, as opposed to 49.99 for the Norton Internet Security package.

Users who wish to determine whether the extra $10 would be well spent must examine their needs carefully. Norton 360’s backup system allows users to store their valuable information either locally or online. Norton 360 hosts 2 gigabytes of space for its users, but this amount of space may be inefficient for some.

In that case, users are able to upgrade to a premium package. With the premium, Norton 360 users can enjoy an additional 25 gigabytes of storage space and backup. Norton 360 takes care of all your file backup needs automatically, providing immediate service for your new and changed files.

If this is not enough, users can schedule their own backup schedule and take care of their own files. When the computer that Norton 360 has been installed on is connected to another, users are able to share files from one PC to the next.

PC Tuneup is the other additional feature that Norton 360 offers to its customers. Its features are constantly running on the computer in the background, taking up precious little space and allowing the computer to run smoothly. There are also services such as de-fragmentation that can be run manually by the user.

Another key difference between the two programs is their flexibility. Norton Internet Security gives its users more opportunities to tweak their settings. Norton 360 offers the same options, but they are much harder for the user to locate, as opposed to Norton Internet Security, which makes the process simpler.

In summation, a customer should purchase Norton 360 if they are able to spend an extra ten dollars for the necessary backup and cleanup features plus their PC is currently without any backup or tuneup capabilities and they are in need. If you are the sort of user who requires these extras and you want a protection for your computer that you can set up and then forget about it, Norton 360 is the choice for you.

On the other hand, Norton Internet Security is the top selection for consumers who are looking to spend less and don’t care about any extra features. Those who already back up their own files and have PC cleaning tools will not need Norton 360. Advanced users will also find Norton Internet Security to be more useful, as its enables them to have full control over every setting.

Users who cannot decide can use a 30 day free trial of both programs, so that they can make the most informed decision. Norton’s website also provides descriptions of each product, as well as a wide range of other virus protection formats.

Difference Between Bose Soundlink 1 and 2

Difference Between Bose Soundlink 1 and 2

As some of you may know, Bose Corporation manufactures a series of portable wireless speaker systems called the Bose SoundLink. These speakers can play sound transmitted over a wireless connection from various types of cell phones and computers. There are multiple versions of the SoundLink, which all use wireless protocols such as Bluetooth. They all include external power-supply adapters, rechargeable batteries, and 3.5mm sockets, which allow sound sources to be connected.

The Creation of the SoundLink

The original SoundLink Wireless Music System was released by Bose in August of 2009. This is a 19-pound speaker unit with a carrying handle, a USB-based wireless transmitter that can be plugged into a computer, and a remote which can control both the speaker and the source. Many reviewers complained about the $550 price that was on the SoundLink when it first came out. These reviewers thought it was excessive for what it was. However, they have sold many units over the years.

Its Evolution

Two years later, the SoundLink Mobile came along. It weighed less than three pounds, and consisted of a speaker unit and a charging adapter, without other accessories such as wireless dongles that the original had. It operates over Bluetooth like many wireless devices do, and it has a protective cover with an on/off switch, much like some of the products from other high-tech companies such as Apple. The regular cover is nylon, but there are leather ones available as well. It is a fixed cover, so the only way to replace it is to use special tools. Inside the machine, there is a lithium-ion battery that can be recharged, four front-facing speaker drivers, and two passive radiators. The SoundLink Mobile was $300 when it was released. Many reviewers liked the sound quality, build quality and portability, but tended to criticize the price and its lack of a microphone. The SoundLink Mobile II came out shortly after, and its cover’s front panel section could fold in half, which reduced the device’s footprint.

What Differences Exist?

The various SoundLink devices are very similar, but they all have their differences. The original SoundLink was a rather large device, while the SoundLink Mobile is rather small. These devices have been heavily criticized for their high price, but audiophiles everywhere continue to buy these units. The SoundLink Mobile II’s main improvement over the original SoundLink Mobile was that its cover could fold and reduce footprint, and naturally, every new device appears to sound better than its predecessor. Nowadays the SoundLink Mini is being used, but the older Mobile units, and sometimes even the originals, are used by music listeners everywhere! Whether they are used for bass-heavy techno music, old-time rock music, or to feel the vibration during every car crash scene on Family Guy, the SoundLink continues to make the experience of audio better.
