Understanding LED Technology By Billings Farnsworth
You might have seen these tiny lights in blue, red and green colors. These are actually LED's or Light-emitting Diodes.
These days, LED technology has advanced in such a way that they will push forward the multitude of applications that LED's have been known for.
LED Technology: The Basics
To have a deeper understanding of what LED technology is all about, here is a quick definition. LED is actually a semiconductor diode which emits light when current is applied to it.
Take a typical mobile phone charger as an example. Once you plug it in, there will be a blue or red indicator light which signals that the mobile phone is charging. This is just one of the many applications of LED technology in which Light-emitting Diodes are used.
As compared to other types of light-emitting devices, LED's do not waste energy. This is because LED's use the 'cold light technology' - where not a great deal of heat is produced by the device.
Applications of LED Technology
Again, LED technology has numerous advantages over other forms of lighting, making it suitable for a number of unique applications.
Here are a few examples:
Ultra-violet LED's are used in water sterilization.
Ultra-violet LED's are used in disinfection.
LED's in general are used as a 'grow light' to enhance the growth of plants, imitating the rays of the sun to promote photosynthesis.
With more advancements in LED technology in the horizon, there is no doubt that this useful technology will continue to be used in a multitude of useful applications in the future.

How to Purchase a Digital Camera
How To Purchase a Digital Camera by Computer Village USA
How to Purchase Digital Cameras
Purchasing a Digital Camera can seem like a daunting task. All those numbers, 6.0 mega pixels, 640 x 480, 64 MB Flash memory , who can understand or convert between different cameras? This tutorial will help you understand what all those terms mean, which aspects of a digital camera you may be interested in while shopping, and be able to compare different cameras with seemingly different descriptive terms. Digital cameras allow for instant access to your pictures. Most cameras on the market have an LCD screen to view the pictures immediately. You can then choose which pictures to keep and which to delete. Using different methods, you can then send the pictures to your computer to email them, print, or store them for future use. Important Characteristics of Digital Cameras Depending on what you want to use the camera for, different characteristics will interest you over others. As your features increase, so does the price. Resolution The resolution of your digital camera tells you how sharp the pictures will come out. The resolution is measured in dpi, or dots per inch. It is an expressed in pixels, each pixel is a dot of color. For example, 640 x 480 has 480 lines from top to bottom and 640 pixels that make up each of those lines. A typical inexpensive camera will be 640 x 480, which is suitable for web or emailing, but if you want to print pictures, anything below 1280 x 1024 is probably unacceptable. When a camera has more than a million pixels, it is commonly referred to as a "mega pixel" camera. For example, a description of a camera may say "Digital Zoom Camera, 1.5 mega pixel, 1280 x 1024 resolution." This camera has over 1 million pixels, which means it is a high quality camera.

3+1 Solution of the Forensic Data Recovery
3+1 Solution of the Forensic Data Recovery by Selina
voteAlong with fast development of information technology and a huge population of computer users, it is more and more difficult for the computer forensic inspector to collect useful evidence from highly skilled and experienced suspicious bodies. The suspicious media containing criminal evidence has a higher possibility of being damaged or destroyed deliberately, rather than being performed a deletion, a format or an encryption. It becomes more and more difficult and complicated during the exploration of the criminal evidence.
Hard disk drive is one of the most common storage systems that may be used to contain the computer criminal evidence. In order to gain access to the data on the hard disk drive through one of the operation systems (e.g. Windows, MAC, Linus), the quality and status of the hard disk drive needs to be in a very good standard. For further analysis and investigation of the data on the media, some special and authorized forensic software tools are also needed. 3+1 Concept Introduction
Case 1: Extract, analyze and validate the data on a working hard disk drive.
There is a couple of computer forensic software available in the market, such as Encase, X-Ways, FinalForensic, F-Response and so on. These software are designed to achieve a high performance in data restoration, data analysis, generation of auto-report and data archive.
When the forensic investigation comes to a situation where the computer hard disk drive is malfunctioning, none of the forensic software will be able to access the data. The malfunctioning hard disk drives may behave like having severe bad tracks, corrupted Master Boot Record (MBR), or being recognized by its 'Alias' in BIOS.
Data Compass is designed to resolve the problems mentioned above. It can be used to extract the data from a defective drive while maintaining 100% integrity of the original data. This is one of the most significant breakthroughs in the computer forensic and data recovery industry.
We will introduce the second and third step of forensic data recovery below:
Case 2: Fully and effectively recover data from instable and bad sectors defective hard disk drive
As far as you know, it is not suggested to recover and analyze data on instable or defective hard disk drives. It is not able extract the data from this kind of hard disk drives due to the instability of the read write head and the likelihood to damage platter. Furthermore, it may also cause a further damage to the whole hard disk drive, which makes the data irrecoverable forever. The most efficient and common approach is to image the data onto a stable donor media, and then proceed to recover and analyze data from the donor.
The technology and algorithm that used to deal with the bad sectors is a crucial and critical part of a cloning tool/procedure. The bad sectors cause system to crash or freeze, making the hard disk drive irresponsive or even being damaged. Data Compass possesses a superb solution for this problem. As you may be aware of, the existing image/cloning tools skips the bad sectors and results in data loss, which corrupt the integrity of the files. The intelligent 'Bad Sector Leap Function' and 'Dynamic Balanced Enhanced Reading Technology' help the users obtain 30% more data than the other image tools. The 'High Efficiency Power Supply System' function is also introduced and integrated into the Data Compass, which is used to resolve the problem of hard disk drive being irresponsive. A multiple of parameters of the reading algorithm are also set to be configurable by users, e.g. the Retry time, Readiness Time, Reset Time, which enable an optimized data recovery.
Obviously, to ensure the security of the original hard disk drive is also important. This has been addressed during our research process. The new technology of 'ShadowDisk' has been developed and introduced in Data Compass after a few years hard research. This technology is also be classified as the 4th generation of image technology. The 'ShadowDisk' minimizes the reading times towards the source drive and protect the further damage to the source drive.
The hard disk drive Bitmap can be also be analyzed by the Data Compass. Different Operation System (OS) will have different bitmap to record the cluster and sector information. In order to find the location of specific file for cloning, the bitmap information is needed. This information are contained in FAT table in FAT system, BT table in NTFS and Block Allocation table in Linux system.
Along with the development of the hard disk drive technology, higher capacity and higher density, the traditional image tools will not be able to resolve all the problems mentioned above. The Data Compass will be a leading technology in the data recovery industry. ATA password protection is also one of the problems that need to be addressed during the evidence collection procedure. The decryption software and the forensic software support up to70% hard disk drives. This is extremely not good enough for the fast developing hard disk drive models. The Data Compass 'Password Filter' function can thoroughly and effectively resolve this problem. Data Compass detects hard disk drive through integrated virtual background files, bypassing the original password protected firmware. It establishes the corresponding firmware modules and then retrieve and recover data directly. This technology is achieved independent from any other decryption software. It will not damage the original password module and support up to 95% of the drive models available in market, include all the Hitachi hard disk drives. Along with the rapid manufacturing of new hard disk drive, Data Compass will be constantly updated and supported the new models. For example, Data Compass has already supported Hitachi 5432 which was manufactured in June 2008.
The function is very easy to use. It is achieved by selecting a corresponding hard disk drive model from the menu. The Data Compass will automatically start the emulation of the firmware. The tips message will also guide the users step by step to complete the restoration of data.
Obviously, the evidence is not only the completed set of data, but also 100% compare to the original data. During the forensic investigation process, the content and the last modified time should be maintained and imaged to a donor copy. No additional data will be introduced during the whole process.
The 'SWPS Technology' is used to maintain the original copy and avoids the affection by virus and Trojan. This is another leading technology developed by SalvationDATA which satisfy the requirement of forensic investigation procedure where the 100% original data is compulsory.
Case 3: Access and analyze data from unrecognized hard disk drives.
The reasons why the hard disk drive is not able to be recognized by BIOS can be categorize into two types: 1. Physical damage. The HPE Pro will be helpful in this case where the read write head or platter needs to be swapped. For more details about HPE Pro, please refer to our website. 2. Firmware corruption, which is quite common. For example, if a certain amount of modules of the firmware are corrupted, then the hard drive may not be recognized by BIOS correctly.
How to access the data quickly and effectively from a hard disk drive which cannot be recognized?
As a professional data recovery research and development department, SalvationDATA released the innovative equipment of Data Compass which is integrated with the 'SA Emulation Technology' in 2008. This new technology allows the hard disk drive to be started up by Data Compass independent on the native firmware copy and access the use data area directly. Nowadays, the capacity of hard disk drive is increasing dramatically, as well as the density. Hard disk drives have a higher possibility of being corrupted or damaged than before. Thus an efficient way to access data independent on local/native firmware is undoubtedly a big advantage. Benefit +1: Recover data at any time, any place, and any environment from any manufacturer of hard disk drives. In terms of computer forensic, evidence should be collected as soon as possible and securely protected. Therefore, ensure the data is being recovered/imaged without external influence is a crucial thing during the forensic evidence collection procedure. The portability of Data Compass is designed to allow you to provide an on-site evidence collection through the USB interface. The Data Compass can be used by connecting with anyone of the laptops at any time, any place and any environment to recover data from any manufacturer of hard disk drives. Data Compass supports a physical or logical data recovery from PATA or SATA hard disk drives, including IDE, SATA, 3.5", 2.5", 1.8" and 1.0" of different manufacturers. Also it can be used for the logical data recovery from the FLASH storage media such as USB pen drive, SD, MMC and FDD.
Data Compass supports more partition formats than the other similar tools, includes FAT16, FAT32, NTFS, Linux Native, Linux Swap, HFS+, and other peculiar partition formats used on special equipment.
The Data Compass adopts the 'Open-source' design on high level recovery/image software. Thus, users are free to use any one of the logical data recovery programs they are familiar with to work with the Data Compass, such as ENCASE, X-WAYS, FianlForensic, F-Response and so on. Data Compass eases the limitation of high level software programs to be used. This is also one of the significant breakthroughs in this industry.
It is no doubt that numerous outstanding technologies are being researched and developed in different sectors, SalvationDATA are always engaged in research on leading high technology of data recovery and computer forensic.

Removing Protection from a USB Flash Drive
Removing Protection from a USB Flash Drive by Derek Rogers
The use of USB flash drive has given everyone the choice between bulky stacks of CDs and a compact travel data storage device. By having the ability to take a lot of files this memory stick, flash memory, flash drive or pen drive is by far the most convenient option to carrying files wherever you go. It basically serves as an electronic filing cabinet, but just like in any product of advanced computer technology, one of the concerns in using USB flash drives is security. That is why some USB's come protected, which works very similar to write protected disks.
However, to some, USB-protect features become a problem in data storage and retrieval. Many of the USB users are seeking ways on how to remove the Write Protected error; a USB-protect setting that is actuated through storage or download errors.
Here are some of the probable causes of Write Protect errors and their possible solutions:
o The use of certain computer software: Sometimes, when saving work from software applications, saving options may cause the automatic actuation of write protection. There's no need to worry because most of the computer software have update versions or troubleshoot settings that can help fix USB problems.
o Drive letter conflicts with network or subset drive: In the context of "system", USB problems may be rooting from driver problems. Check your computer's mount manager and try fixing the drive letter assignments; especially those concerning USB flash drive mounts. When this happens in a computer using Windows XP, the computer immediately recognises the problem. When configuring for write protect errors, make sure that you know what you are doing. It would be wise to ask a technician to face this kind of problem if you are lacking skills in handling this.
o The new external drive is not partitioned: New external drives usually come unformatted and un-partitioned. You can fix this problem by clicking on the Windows Disk Management.
o The use of Windows Server 2003 Enterprise and DataCentre Edition: This program usually does not assign letters to new fixed drives, which means USB and Firewire are usually "fixed". Check the Storage Area Network or Administrator for the drives may have been mounted accidentally, leading to USB-protect errors.
o Drive Encrypted: Some USB flash drives and other external hard drives readily have encryption software. This software usually has options to divide the data storage into two parts, the encrypted part and the unencrypted part. The unencrypted part appears on all computers and is readily accessible or can be accessed by using the password required by the encryption software.
o Incorrect installation of computer tools: Sometimes, this results to the computer's inability to assign letters to the new drives. If this happens, it is suggested that you uninstall the software.
o Filter driver problems: This manipulates the communication between the software and hardware; this is a possible cause of USB-protect problems.
o Other third party software: Anti-virus, anti-spyware, personal firewalls, CD/DVD writing software and other protective software usually controls the drivers, causing strange effects to USB flash drives.
Simple troubleshooting tips for write-protect errors:
o Try to locate the switch located at the body of the USB, if there is one, then turn the switch to the other side to turn the protection off.
o The problem may be caused by virus activity, get it scanned by an updated anti-virus.
If none of the above mentioned tips work, perhaps your USB may have gone corrupted. Ask a technician about your problem. If your USB flash drive goes beyond salvage, then it may be the right time to buy a new one.

A perfect solution to reduce your spam
A perfect solution to reduce your spam by Meredith Wilson
Meredith is trying to spread the word in the communicity about how to stop spam. She has tried a number of anti-spam software packages and been disappointed. Now, she has found a solution that really does stop spam for herself and her team.
Meredith has tried the one month free offer for http://www.spamdetour.com.au/ and her spam has disappeared.
Most anti-spam systems don't work. How can you get an effective anti-spam solution
Despite the constant improvement in technology, the problem of spam has been getting worse in the past year, increasing in volume and in the sophisticated level of crime. Most of the anti-spam software out there doesn't really work. I have found a solution which stops spam, requires no installation, costs very little and even in a small business will pay for itself very quickly.
The problem of spam has been getting worse. In recent years spam has been an annoying nuisance such as advertising. There has been a considerable worsening of the problem with an enormous increase in the number and sophistication of fraud, being perpetrated through spam.
I first became aware of how serious the problem is when I received an email which advised me that an additional person has been authorised to access my online bank account. I am fairly computer literate and well aware of the common deceptions which are delivered by email, but this one looked particularly convincing. So much so that I phoned the bank to check if it was real (of course it wasn't genuine).
I thought, well, if someone as computer literate as myself could be even half-convinced that the email was genuine, undoubtedly some of the novices on the internet would fall for the trap. If the spammers send out a million emails, they only need to "play the numbers" to uncover a few naive internet users who will fall for the spammers criminal tactics.
I then asked around some of the most computer-literate people I know. Several of them had fallen victim to scams. There is no doubt that these criminals are getting much smarter and more sophisticated in the types of frauds they perpetrate.
For example, one of the most highly computer literate people I know recently fell victim to scam which was related to eBay. He had recently purchased an item on eBay. Shortly afterwards he received an email asking for his credit card details. As the two events happened around the same time, my friend mistakenly thought that the spam was a genuine request from eBay for credit card details. After a day or so my friend realised his mistake, but meanwhile he was defrauded from his credit card account.
Stories abound about people who have fallen for quite simple frauds, such as the Nigerian scam. I believe people need to have some level of common sense to avoid scams as obvious as those. Of greater concern is the new spate of sophisticated spam scams.
Spam statistics show an increase of 30% in the past year. Today, 80% of the email in the world is spam. Why is spam increasing so fast? The answer is simple. Spam fraud is a huge success for the criminals behind it. The more profitable the fraud, the more the criminals will invest in developing smarter methods of stealing money from you.
To make matters worse, some of the people who sell protection software are allegedly the same people who are spreading the problem. There have been some notorious cases of people and organisations who develop new viruses and also sell the anti-virus solutions.
What can you do to protect yourself?
Companies such as Symantec are selling protection software. (By the way I am not suggesting for one moment that Symantec are doing anything disreputable). But, is a software solution really the best way for you go? After all, you have to install it on your computer so it's just one more software item to slow down your PC. The other concern about software solutions is that in order for them to work you have to firstly bring the spam into your network. There are many disadvantages to this, including that the traffic itself clogs up your internet link and your server. Also, once the spam is inside your network or your computer, if the spam filter does not deal with it correctly then you will have to deal with the consequences.
There is a simpler and smarter way to protect yourself against spam. The answer is anti-spam managed filtering services. These services come in a couple of different types. Some of the anti-spam services are marketed to large business and government clients.
There are also some anti-spam services which are designed for small to medium businesses. It is even available to individuals. I believe that one of the most effective systems for small to medium business is the SpamDetour service - the worldwide link is http://www.spamdetour.com/.
I employ four people in my office and they are all very busy. I hate seeing them waste their time with spam. I tried a free trial of SpamDetour at first as I was unconvinced about the promises it made about stopping 99% of spam. It took one day before the SpamDetour started working, and immediately, the spam stopped for myself and my colleagues. It was like suddenly being in the countryside and experiencing golden silence, after the noise and traffic of the city. Wonderful!
SpamDetour requires no installation or configuration and is therefore suited for people and/or organisations with little or no computer / internet skills.
The biggest advantage of spam filter managed services over anti-spam software is that the managed services keep the spam far away from your network and away from your computer.
Would you invite criminals inside your house and then deal with the problem of removing them? Obviously not. You would keep the criminals as far away as possible. Yet that's how most anti-spam systems work; they bring spam into your network to be dealt with.
Managed anti-spam services work in a completely different way to software based anti-spam systems. The managed anti spam services create a new location for your email domain, which is generally at an Internet Service Provider site. This acts as a spam trap. Then, once your email reaches the spam trap the filter takes over and directs genuine email to the real user, and it directs spam to a storage area on the anti-spam managed service server where it cannot do any harm to you, the user, or to your business.
Of course, no anti-spam system is 100% accurate. From time to time it is possible that a genuine email will be classified as spam, or that spam will sneak past the filter and reach into your computer or your network. Still, this is much less likely to happen with a managed service than with an in-house spam filter.
The best anti-spam managed services on the market allow you to log in and check your spam to pick up any errors in the system, add blacklists and whitelists, fine tune the system. If you find any genuine emails on the anti spam database you can pick them up from the spam trap and direct them to your own network and computer.
If you are a high-tech internet user, a computer specialist or a large organisation you may well have your anti-spam protection strategy worked out. On the other hand, if you are an individual or a small to medium business then an anti-spam managed service is a simple, practical and cost effective solution.
A major benefit of the anti spam managed service is that it saves time. If you add up the millions of people who have to manually pick spam out of their email every day, waste time dealing with fraudulent spam, read unwanted advertising etc., the cost to the economy is enormous - billions of dollars each year.
Some of the anti-spam managed services offer a free trial or money back guarantee. I believe that anti spam managed services, with the anti-spam technology provided by experts are the only way the world is going to combat the problem of spam.
One last thing - I am a big advocate of local support. The team at SpamDetour have been fantastic. We have had a few queries from time to time and we have been able to call their Melbourne or their Brisbane office and they have been able to give us an immediate answer. It is fantastic to deal with a local company that gives honest old-fashioned service.

Meredith Wilson is an accountant living in Australia. One of her interests to develop the internet for the purpose of providing genuine benefits to the community, and to reduce exploitation of the medium.
Meredith is trying to spread the word in the communicity about how to stop spam. She has tried a number of anti-spam software packages and been disappointed. Now, she has found a solution that really does stop spam for herself and her team.
Meredith has tried the one month free offer for http://www.spamdetour.com.au/ and her spam has disappeared.
Most anti-spam systems don't work. How can you get an effective anti-spam solution
Despite the constant improvement in technology, the problem of spam has been getting worse in the past year, increasing in volume and in the sophisticated level of crime. Most of the anti-spam software out there doesn't really work. I have found a solution which stops spam, requires no installation, costs very little and even in a small business will pay for itself very quickly.
The problem of spam has been getting worse. In recent years spam has been an annoying nuisance such as advertising. There has been a considerable worsening of the problem with an enormous increase in the number and sophistication of fraud, being perpetrated through spam.
I first became aware of how serious the problem is when I received an email which advised me that an additional person has been authorised to access my online bank account. I am fairly computer literate and well aware of the common deceptions which are delivered by email, but this one looked particularly convincing. So much so that I phoned the bank to check if it was real (of course it wasn't genuine).
I thought, well, if someone as computer literate as myself could be even half-convinced that the email was genuine, undoubtedly some of the novices on the internet would fall for the trap. If the spammers send out a million emails, they only need to "play the numbers" to uncover a few naive internet users who will fall for the spammers criminal tactics.
I then asked around some of the most computer-literate people I know. Several of them had fallen victim to scams. There is no doubt that these criminals are getting much smarter and more sophisticated in the types of frauds they perpetrate.
For example, one of the most highly computer literate people I know recently fell victim to scam which was related to eBay. He had recently purchased an item on eBay. Shortly afterwards he received an email asking for his credit card details. As the two events happened around the same time, my friend mistakenly thought that the spam was a genuine request from eBay for credit card details. After a day or so my friend realised his mistake, but meanwhile he was defrauded from his credit card account.
Stories abound about people who have fallen for quite simple frauds, such as the Nigerian scam. I believe people need to have some level of common sense to avoid scams as obvious as those. Of greater concern is the new spate of sophisticated spam scams.
Spam statistics show an increase of 30% in the past year. Today, 80% of the email in the world is spam. Why is spam increasing so fast? The answer is simple. Spam fraud is a huge success for the criminals behind it. The more profitable the fraud, the more the criminals will invest in developing smarter methods of stealing money from you.
To make matters worse, some of the people who sell protection software are allegedly the same people who are spreading the problem. There have been some notorious cases of people and organisations who develop new viruses and also sell the anti-virus solutions.
