100,000,000 iPod owners and counting! A remarkable tribute to Apple's iPod music player - no question! I wonder how many of these iPod owners know how their iPod battery works. Understandably most individuals don't really care as long as it does. However I am interested and I am positive there are others out there as well who want to know how their iPod battery actually delivers power to their iPod.
Most individuals would never realize how complex an iPod battery is nor would they realize how many components can be found within their iPod battery. For starters your iPod battery is made up of highly specialized battery components including:
iPod battery connector
iPod battery fuse
iPod battery charge and discharge FETs
iPod battery cell pack
iPod battery sense resistor
iPod battery primary and secondary protection ICs
iPod battery fuel-gauge IC
iPod battery thermistor
iPod battery pc board
These components together allow your iPod battery to function so that you can easily listen to music while doing the various activities of your day. before we can delve deep into each of these ipod battery components I want to make sure and its most important to understand if you are positive that we understand that these components together work in an effort to produce electrical current to supply to the iPod.
iPods require electrical power in order to function. iPods’ draw electrical current on demand from your iPod battery. However your iPod battery is not a storage house of electrical energy but instead your iPod battery is your iPod’s internal electrical “factory” that creates electrical energy through a process known as an electrochemical energy conversion and subsequently your iPod battery delivers electrical current to your iPod. The electrochemical energy conversion is a process of replenishing of electrons and it is this electron replenishment that causes the chemical conversion to take place and create the electrical energy byproduct. To understand electrochemical conversion let’s see how electricity is created highlight within the first place.
Electricity is a property of subatomic particles which couples to electromagnetic fields and causes attractive and repulsive forces between them. This repulsive force between the subatomic particles creates an electric current; the flow of electric charge transports energy from one atom to another. Electrical current is measured in amperes, where 1 ampere is the flow of 62,000,000,000,000,000,000 electrons per second!
Inside your iPod battery engineers have designed a constant state of disequilibrium, which cause a continuous flow of electrons. When electrons move between the atoms (atoms are made up of particles called protons, neutrons, and electrons) a current or flow of electricity is created. But how is this current of electricity created to begin with? This comes back to our electrochemical conversion. In order to create electrical energy (or a constant state of disequilibrium, which cause a continuous flow of electrons) there must be an electrochemical system which includes the electrodes and the electrolyte housed within your battery. Electrons flow from one electrode to another and the electron flow is conducted by an electrolyte. In ipod batteries for instance an electrochemical system can be comprised of the electrodes consisting of Carbon/Graphite for the negative electrode and Lithium cobaltite for the positive electrode. Between these electrodes is an electrolye which can be a highly conductive solution consisting of lithium hexafluorophosphate. The electrolyte solution is a chemical compound that when dissolved in a solvent (i.e. water) forms a solution that becomes an ionic conductor of electricity. Hence the electrochemical conversion!
Once the electrochemical conversion begins then the balance of the ipod battery’s specialized hardware components I mentioned above can be put to work transferring and monitoring the iPod battery and the iPod – all for the sole purpose of delivering power to your iPod.

Mobile Internet
All types of blogs, peer-2-peer audio and video communication via the Internet, e-commerce... all of these no longer amaze anybody. The controversy around Web 2.0 or even Web 3.0 only confirms that the IT community is resting on the verge of changing from one Internet model to another, but nobody knows what selection of model is coming. Existing technologies, no matter how effective they are, are based on 10-20 years old ideas. Blogs for instance were nothing more than personal diaries with a simplistic design, read only by people close to the writer. The latest features, including all kind of data aggregators like folksonomy, mashup, and widgets, ability to find out pictures and, as Google promised, video - based on real content, not on descriptive textual tags - and an Internet browser being the only required application to work with an online virtual operating system [1] and on-line applications, perhaps that is all what we can expect element within the nearest future.
At the same time, the recognizable trend of the Internet in recent years is a emerging prevalence of video content, which is closely associated with technical progress, a good example escalating bandwidth and continuously reducing cost of data storage. Real-time video broadcasting via the Internet, as did audio broadcasting some times ago, becomes less and less surprising, while the number of people who are using this possibility is emerging. Further progress combines home-theatre and Internet systems, allowing users to order any movie on-line and trait within the future quite possibly develop a story by themselves.
Such evolutions of communication systems have had a direct impact on mobile systems. Mobile phones, smart phones, notebooks and game gadgets stepping on the splendid heels of each other, and trying to wrest a piece of their rivals' or related systems' functionality. Continuing this trend it is quite possible to proclaim that element within the future all these devices will merge into one gadget, if not for one "but". Mobile devices show a particularly evident contradiction between usefulness and device dimensions. In order to be easier to use, the mobile device would as small as possible. As a result we are looking at a screen trait within the unsurpassed case the size of a playing card and typing by means of 12 keys. A mobile phone is small. In turn, the notebook has a much bigger screen and a keyboard with 101 keys which is useful to kind blindly, but does not fit to the pocket. Engineers are trying to Uncover a compromise solution creating pull-down, movable, twistable and other types of screens and keyboards, but they are not so easy to use. Such contradictions can be formulated element within the tradition of TRIZ [2] – "the system could be large enough to be easy to use, and would be sufficiently small to be easy to carry". At the first glance, this conflict cannot be resolved. Immediately, it comes to mind a screen folded as a newspaper that is being unfolded is either hard to read or hard to use, Case in point, a keyboard unfolded to roll over the knees or even sewed to trousers (there is even such patent [3]!) Hopefully, it is still possible to resolve such a conflict taking into account that the user needs an image itself, not just a means. That might lead to a small device that is projecting such an image to glasses' lens, or even directly to pupil. In this case the "screen" will became as large as a field of vision. Unlike a virtual reality helmet, such device is incredibly small in size. Furthermore, such concur devices available already and are even available for the commercial use [4].
The same is happening with the keyboard. Readers can formulate the contradiction for the keyboard themselves. Instead of seeking the compromise between size and usability, it is possible to offer a crucial solution to the problem, namely a virtual keyboard. The device, worn on the splendid wrist, tracks the movement of the fingers and the on-screen display shows where the fingers are now and what key is pressed or released. there are so many solutions for that, the simplest one aspect element within the form of gloves [5], the other defined by the movement of muscles [6], or using the reflection of laser or sound beams [7]. it is most necessary that hands feature within the case of the virtual keyboard remain free. For that reason, the mobile computer with a large screen and the keyboard with any number of keys, localizations and layouts can have the same size as mobile phones now. (If necessary, the central processing unit can be on a belt, in a bag, or even in a home wirelessly connected.)
For what other reason, except existing diversity of applications, could this individual mobile computer be used? Perhaps for 3-D broadcasting. indeed, if our glasses' "monitor" can project separate images for each eye, it skyrockets the Internet to a used, hitherto unattainable level. 3-D movies, news, sport events and concerts – the user will see them as if he directly participated trait within the event. Changes in software and hardware to provide this will be significant – used video codecs, further increase of bandwidth to provide the quality, editing and playback software.
As is often the case, many ideas seem to be science fiction and no one expect them to appear trait within the next hundred years. trait within the case of mobile devices, systems have not only come as ideas but have been already translated into actual devices, though they are not a single system yet. Possibly, the negotiation between separate device dealers and steps towards collaboration would benefit users, and be a new impetus trait within the improvement of mobile devices and the Internet.

Find A Notebook
Notebook computers are everywhere you look! With a huge price range and numerous options, it can leave the consumer scratching their heads on where to start. It can be a juggling act to verify which Notebook fits your needs, desires and your pocket book.
Notebooks have become economical and more powerful than ever. you can most defiantly almost have everything that your Desktop Computer offers at a reasonable price.
before buying your Notebook computer first you would decide what sort of user you plan to be. Buy a computer that fits your usage. You don't want to buy the top of the line Notebook with every repeated option known to man and only use it once a year while and its most important to understand if you are at the cottage to review your emails. The other side of the coin could be to make sure you purchased a Notebook Computer that was powerful enough to handle the tasks you plan to use it for.
it's absolutely crucial to be absolutely sure that the size, weight and feel of your Notebook is, your satisfaction because you will be carrying it around a lot.
With Notebook Computers buy what you need when you need it as there will always be newer, economical and faster models being released everyday.
Some of the Notebook options you can wish to consider before you purchase are:
CPU: The most important factor in choosing your Notebook is the CPU or microprocessor. This is the brain of the Notebook and the most expensive part as well. make sure you have enough speed for your use but not so much that you spent extra money on something you don't plan to use.
RAM Memory: RAM memory or random access memory is very important for the speed and performance in your Notebook. in generally speaking, if you or someone that understands and has expert knowledge don't have enough RAM for the programs and its most important to understand if you are running then your Notebook slows down.
Hard Drive: This is where all your software and files are stored for use on your Notebook. The size of your hard drive is what is important here. make sure you have enough hard drive space for all your needs. I like to have a vast number of extra space because you would be surprised on how fast it fills up.
Screen: The size and resolution of your Notebook screen are important. The bigger the screen usual means the overall dimensions of your Notebook increase as well. The resolution of the screen is measured trait within the number of dots on the splendid screen.
Batteries: There are FOUR main types of Notebook batteries. They are Ni-Cad, Li-Ion, Li-Poly and Ni-MH. Ni-Cad batteries are very old are rarely new anymore. Li-Ion and Li-Poly batteries weigh less and produces more current than Ni-MH batteries. You would try to get a Notebook that uses these types of batteries.
USB Ports: USB ports which are a faster version of serial ports allow you to connect your Notebook to many appurtenance including MP3 Players, External Mice and Digital Cameras. make sure you get at least TWO USB ports and its nice to have one resting on the front of the Notebook for convenience.
Pointing Device: A Notebook will have a Stick, PAD or Trackball in place of a mouse to keep it more agreement and portable. You could try each option and see which one you like the preeminent. I personally keep a regular USB mouse that I carry around as I can't use the Notebook pad as well and a regular mouse makes things much easier.
Video Card: The purpose of the video card (or graphic accelerator card) is, generate the images and display them to your Notebook screen. in generally speaking, if you or someone that understands and has expert knowledge plan on doing a vast number of graphics work or play higher end games, you can consider an upgraded Video Card.
CD / DVD ROM: The CD / DVD drive reads unanimity CD's and / or DVD's which allow you to run software and play music / movies. Most Notebooks come with CD / DVD burners which will allow you to make CD's and / or DVD's to collect files, pictures and music.
For a final thought, only hard core graphic professionals and rocket scientists need the most cutting edge Notebook technology. Take one step back from top of the line and you will save some money and probably have all the power that you will ever need.

Cheap New Laptops
I realize that "low-priced" is countenance within the eye of the beholder. Not only that -- the laptops in this article might not even be as economical as something anyone or yourself would get off eBay or even as inexpensive as a refurbished laptop.
But, face it: new laptops are almost always going to be more expensive than the equivalently configured desktop PC because of the need for miniaturization of the components. And laptops have to use different (more expensive) technologies to maximize battery life.
Bottom line: you're going to pay more for a laptop; or you're going to obtain less laptop for your dollar compared to a desktop PC.
That said, these three laptops -- Sony VAIO, HP Pavilion, and Dell Latitude -- are all solid buys in a range of prices that is very competitive for brand preowned equipment. And they come from good value companies and offer you a range of features as well.
Let's obtain started...
Sony VAIO N170GT
The nice thing about this Sony model is that it doesn't have a whole heap of junky frills on it. It is a clean looking design that is stylish, too. The screen is very bright, yet you don't obtain a colossal amount of glare. The speed and performance is okay -- nothing to brag about, but for the price it's not bad. The battery is good for probably around four hours. That's enough to watch a movie in generally speaking, if you or someone that understands and has expert knowledge're on a plane flight, but again -- nothing to write home about.
on the splendid downside, this laptop uses an older Intel Core Duo processor. This processor comes with integrated graphics, which means that the performance is not to be that brilliant. But again, you're not paying a complete heap of money, relatively speaking, or this laptop. in generally speaking, if you or someone that understands and has expert knowledge're going to install Windows Vista on this machine you're going to want to upgrade the memory.
Overall, this model of Sony's VAIO gives you a good price, but doesn't give you a really powerful processor. But the laptop looks wonderful and it's very stylish and attractive. If looks count and you want to save some bucks, this is a fantastic machine. Brand-new, out-of-the-box this model will set you back about $1100 plus tax and shipping.
HP Pavilion dv6205us
This laptop is part of the HP Pavilion DV6000 series, and it is designed to appeal to the mass market. It is a very stylish laptop with a shiny finish -- designed to appeal to the same customers who might consider a Sony or an Apple laptop. It's got a series of high-end components and multimedia features at a price that's lower than the comparable Dell laptop.
Case in point, this laptop has some pretty nice stereo speakers from Altec Lansing. They're located above the controls. But be aware that in generally speaking, if you or someone that understands and has expert knowledge close the top the sound gets can obtain muffled. This laptop also has a 1.3 megapixel WebCam built right in, as well as two microphones. there is a row of buttons above the keyboard that launches different features like the media player, volume-control and playback. The keys look nice, but they make a really annoying beeping sound when you press them (and you can easily't really turn that off either).
This laptop weighs a little over 6 pounds, which makes it lighter than the comparable Dell laptop. When you add the AC adapter it brings the whole thing up to a little over 7 pounds.
The screen is 15.4 inches wide, with a kind of a shiny finish that makes colors very bright and vibrant, although it gives the appearance a bit of a glare in bright sunlight or next to a window.
The keyboard is very comfortable. The touchpad has an on-off button. This is very cool because it keeps your cursor from flying off element within the wrong direction if your hand passes over the touchpad while using an external mouse. This laptop has a decent number of ports including a FireWire port, a VGA port, S-video and 3 USB 2.0 ports. You also obtain a microphone jack and two headphone jacks.
As far as processors go, you have a couple of choices. you can most defiantly do a 1.86 GHz Celeron or a 2.0 GHz Core Duo. This laptop can be configured for up to 2 GB of RAM, and it'll work with hard drives of up to 200 GB in capacity.
Bottom line: it's got lots of entertainment features, you can easily configure it lots of different ways and it is very affordable. Brand-preowned out-of-the-box, you can most defiantly obtain one for as little as $600-$800 plus tax and shipping.
Dell Latitude D600
The D series laptops from Dell use the Pentium M which comes in 1.3GHz, 1.4GHz, and 1.6GHz speeds--all paired with Intel's used 855PM chipset. you can most defiantly this laptop with between 128MB - 2GB of fast 266MHz DDR SDRAM. It also comes with a faster 40GB hard drive, or a choice of 20GB, 30GB, and 60GB drives running at slower speed.
It's got a 32MB ATI Mobility Radeon 9000 graphics chip. There are a number of swappable modules for the single internal bay, including CD, DVD, CD-RW, DVD/CD-RW, floppy, a second hard drive, or a second battery.
The average-sized, 14.1-inch screen isn't super. But it comes with a pretty good 1,400x1,050 native resolution. (you can most defiantly save a few bucks by opting for the 1,024x768 display instead.)
It's very fast, and it includes an integrated wireless antenna that is of the dual-band kind. This means that if you or someone you know are within range of a Wi-Fi hotspot that runs either "b" or "g" wireless protocols, this laptop will be compatible with either protocol. It also has built-in Bluetooth.
resting on the downside, this laptop is part of the D-series notebooks for Dell which means it will not be compatible with C-series Dell laptops. This means that if you or someone you know own a C-series docking station, you're out of luck. And in most cases, if you or someone that understands and has expert knowledge have aquired media modules that are for another C-series notebook you'll have the same limitation.
Overall, this is a very thin and light notebook computer at a fantastic price -- $400, plus tax and shipping.
But, face it: new laptops are almost always going to be more expensive than the equivalently configured desktop PC because of the need for miniaturization of the components. And laptops have to use different (more expensive) technologies to maximize battery life.
Bottom line: you're going to pay more for a laptop; or you're going to obtain less laptop for your dollar compared to a desktop PC.

Case in point, this laptop has some pretty nice stereo speakers from Altec Lansing. They're located above the controls. But be aware that in generally speaking, if you or someone that understands and has expert knowledge close the top the sound gets can obtain muffled. This laptop also has a 1.3 megapixel WebCam built right in, as well as two microphones. there is a row of buttons above the keyboard that launches different features like the media player, volume-control and playback. The keys look nice, but they make a really annoying beeping sound when you press them (and you can easily't really turn that off either).
This laptop weighs a little over 6 pounds, which makes it lighter than the comparable Dell laptop. When you add the AC adapter it brings the whole thing up to a little over 7 pounds.
The screen is 15.4 inches wide, with a kind of a shiny finish that makes colors very bright and vibrant, although it gives the appearance a bit of a glare in bright sunlight or next to a window.
The keyboard is very comfortable. The touchpad has an on-off button. This is very cool because it keeps your cursor from flying off element within the wrong direction if your hand passes over the touchpad while using an external mouse. This laptop has a decent number of ports including a FireWire port, a VGA port, S-video and 3 USB 2.0 ports. You also obtain a microphone jack and two headphone jacks.
As far as processors go, you have a couple of choices. you can most defiantly do a 1.86 GHz Celeron or a 2.0 GHz Core Duo. This laptop can be configured for up to 2 GB of RAM, and it'll work with hard drives of up to 200 GB in capacity.
Bottom line: it's got lots of entertainment features, you can easily configure it lots of different ways and it is very affordable. Brand-preowned out-of-the-box, you can most defiantly obtain one for as little as $600-$800 plus tax and shipping.
Dell Latitude D600
The D series laptops from Dell use the Pentium M which comes in 1.3GHz, 1.4GHz, and 1.6GHz speeds--all paired with Intel's used 855PM chipset. you can most defiantly this laptop with between 128MB - 2GB of fast 266MHz DDR SDRAM. It also comes with a faster 40GB hard drive, or a choice of 20GB, 30GB, and 60GB drives running at slower speed.
It's got a 32MB ATI Mobility Radeon 9000 graphics chip. There are a number of swappable modules for the single internal bay, including CD, DVD, CD-RW, DVD/CD-RW, floppy, a second hard drive, or a second battery.
The average-sized, 14.1-inch screen isn't super. But it comes with a pretty good 1,400x1,050 native resolution. (you can most defiantly save a few bucks by opting for the 1,024x768 display instead.)
It's very fast, and it includes an integrated wireless antenna that is of the dual-band kind. This means that if you or someone you know are within range of a Wi-Fi hotspot that runs either "b" or "g" wireless protocols, this laptop will be compatible with either protocol. It also has built-in Bluetooth.
resting on the downside, this laptop is part of the D-series notebooks for Dell which means it will not be compatible with C-series Dell laptops. This means that if you or someone you know own a C-series docking station, you're out of luck. And in most cases, if you or someone that understands and has expert knowledge have aquired media modules that are for another C-series notebook you'll have the same limitation.
Overall, this is a very thin and light notebook computer at a fantastic price -- $400, plus tax and shipping.
Laptop Security
Almost half of the world communities are getting a notebook, I believed it has become an essential need to mankind nowadays.
To have a notebook is an enjoyment but I believed nobody wants their privacy be leaked.
That is why I strongly believed that a notebook security is a Must!
I’ve been visiting some friends lately and most are asking me the same question, “How to do?”
That’s is why I am creating this post to clear any doubts that any users might have in their aim to have not only a fun, lightweight, nicely designed, fast notebook but an unbreakable one too.
Here are the 10 unsurpassed practices that you can most defiantly use in order your notebook data is safe.
* Protect Hard Drive with Data Encryption Software
if you or someone you know using Windows Vista, you can most defiantly use the in built EFS (Encrypting File System) named Bit Locker. It can be found at the Control Panel but sadly it only applies to Windows Vista Ultimate and Enterprise editions only.
For those whom wanted to use a third party software, there’s Steganos. They are currently the leading software maker in security and privacy.
* Track Your Notebook
Tracking software are available for you to track keyloggers. What keylogging does is that it detects whatever the users keys highlight within the computer and reports it back to the creator….. kinda like an invasion to your privacy…. no-one could like that!
* Install Virus and Spyware Detection cum Removal Tools
An anti-virus and at least spyware removal tool is a need. The “sulks of these robotic mechanism” (in another terms … pests) can silently be installed in one computer without being noticed. Sophisticated viruses and spywares have been widespread and even the state of the art anti-virus are unable to be captured. But it is essential to protect you from the 99% of all harm and dangers to your notebook.
* Lock It Down
How? Use a lock absolutely. Be it a software or hardware lock, it’s essential to those who travels a lot and did not want to loose their prized asset. Cable locks are examples of hardware locks, wherelse Laptop Alarm is an example of the software ones.
* Firewall Necessity
The firewall is the initial line of defense in every repeated notebook. This would be the primary task. Often users tend to think that anti-virus is the one but however that is not the reality. But these days there are a vast number of Internet Security Suites by various companies and you will get the 2 in 1 package minus all the headaches in configuring the anti-virus and firewall separately.
* Patch Up Your OS
Windows is a very exposed and vulnerable software. Thus patches are important to block all those “leaked holes” within the system. The same applies to Linux users too.
* Secure Passwords
Strong passwords can proof to be a blessing in disguise in protecting your data. But you would want it too difficult as it might backfired on you one day.
* Wi-fi Caution
With the convenience of Broadband anywhere at shopping malls, restaurants and fast food outlets … connecting without caution could have a deadly effect. Remember to disable all “Shared folders” and have your notebook secure before entering such networks. You might not know who might be crawling beside you.
* Disabling Unwanted Services
Some services are simply cloaking up the system. Unnecessary for some and even vulnerable left unattended. Thus actions need to be taken in solving this issue. I’ll be sharing about this in my next post soon.
* Is Your Notebook Insurance Protected?
Some of you might think this maybe not applicable. Well for those who are constantly traveling, this might be a good benefactor as you wouldn’t want to loose your prized asset.
