The amazing technology of Bluetooth presents a great way of exchanging data between two wireless devices. Unlike telephones, there are no wires or messy leads to worry about. You can enjoy wireless communications with short distances of up to thirty feet.
Bluetooth also offers interoperability, meaning that you can use your portable Bluetooth device to connect with existing Bluetooth points. This way, you won’t have to carry a data lead or CDs of drivers around with you everywhere you go. You can enjoy the best of wireless without having to worry about installing your software.
With today’s Bluetooth, you can use your PDA and cell phone to surf the net or check emails as you travel. If you are in the business field, this can be very beneficial, especially if you like to check your email throughout the day. Bluetooth will enable you to check your email no matter where you are – which is great news for those who like to travel.
Bluetooth will also enable to you to transfer files as well, such as MP3 and photo to and from your mobile device. Bluetooth dominates the world of short range wireless, enabling you to do more than you may have thought possible.
One of the best things to Bluetooth and something everyone loves is the wireless headset. Bluetooth offers wire free headsets for your cell phone or computer, which is great for those who like to walk around or talk on the phone in the car, without having to worry about your hands getting in the way.
To make things even better, you can use a Bluetooth GPS device for satellite navigation on your PDA, laptop, or mobile. If you travel – this can be really great to have.
Bluetooth is a high speed, low powered wireless link technology that’s designed to connect phones or other portable equipment together with little to no work required by the user. Unlike infrared, Bluetooth doesn’t require line of site positioning to work.
Current prototype circuits are contained on a board that is 0.9 cm square, with a much smaller circuit board being developed.
When one Bluetooth device comes in contact with another, they will automatically exchange addresses and details of capability. Then, they can establish a 1 MB link with security that they will use as required. The protocols involved with handle both data and voice, with a very flexible topography.
The technology achieves its goal by embedding tiny, non expensive short range tranceivers into the devices available today. The radio operates on the 2.45 GHz frequency band, and supports up to 721 KBps, along with three voice channels.
Each devices offers a unique 48 bit address from the IEEE 802 standard, with the connections being point to point or multipoint. The max range is 10 meters, although it can be extended to 100 meters by increasing the power. The devices are also protected from radio interference by changing their frequencies, also known as frequency hopping.
What’s important, is the fact that Bluetooth devices won’t drain battery life. The specification targets power consumption of the device, limiting the drain on the battery. The radio chip will consume only 0.3mA in stand by mode, which is less than 5% of the power that standard phones use.
Bluetooth will also guarantee security at the bit level. The authentification is controlled by the user via a 128 bit key. The radio signals can be coded with anything up to 128 bit. With the frequency hopping, Bluetooth is already very
hard to listen into.
The baseband protocol is a combination of both circuit and packet switches. Slots can be reserved for synchronous packets as well. Each packet will be transmitted in a different hop frequency. Normally, a packet covers a single slot although it can be extended to cover up to five slots.
Bluetooth can also support data channels of up to three simultaneous voice channels. Therefore, it’s possible to transfer the data while you talk at the same time. Each individual voice channel will support 64 KB.
From a technical standpoint, Bluetooth is very different indeed. It’s the best wireless method in the world, surpassing even infrared. For communication on the go, Bluetooth is indeed very hard to compete with.
Bluetooth has a lot to offer with an increasingly difficult market place. Bluetooth helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by LAN (Local Area Network).
In the key marketplace, of wireless and handheld devices, the closest competitor to Bluetooth is infrared. Infrared holds many key features, although the line of sight it provides doesn’t go through walls or through obstacles like that of the Bluetooth technology.
Unlike infrared, Bluetooth isn’t a line of sight and it provides ranges of up to 100 meters. Bluetooth is also low power and low processing with an overhead protocol. What this means, is that it’s ideal for integration into small battery powered devices. To put it short, the applications with Bluetooth are virtually endless.
Disadvantages
Bluetooth has several positive features and one would be extremely hard pressed to find downsides when given the current competition. The only real downsides are the data rate and security. Infrared can have data rates of up to 4 MBps, which provides very fast rates for data transfer, while Bluetooth only offers 1 MBps.
For this very reason, infrared has yet to be dispensed with completely and is considered by many to be the complimentary technology to that of Bluetooth. Infrared has inherent security due to its line of sight.
The greater range and radio frequency (RF) of Bluetooth make it much more open to interception and attack. For this reason, security is a very key aspect to the Bluetooth specification.
Although there are very few disadvantages, Bluetooth still remains the best for short range wireless technology. Those who have tried it love it, and they know for a fact that Bluetooth will be around for years to come.
Below, are 10 benefits and reasons to use Bluetooth
technology.
1. Wireless
As you probably already know, there are many benefits and advantages to using wireless devices. Along with improving safety as a result of eliminating wires you don’t need, wireless also offers you plenty of other advantages. When traveling with your laptop or other wireless devices, you’ll no longer have to worry about bringing connection cables.
2. Bluetooth is actually inexpensive
The technology of Bluetooth is cheap for companies to implement, which results in lower costs for the company. These savings are then passed from the company on to you.
3. Bluetooth is automatic
Bluetooth doesn’t have you set up a connection or push any buttons. When two or more devices enter a range of up to 30 feet of each other, they will automatically begin to communicate without you having to do anything.
4. Standardized protocol
Bluetooth is standardized wireless, meaning that a high level of compatibility among devices is guaranteed. Bluetooth will connect devices to each other, even if they aren’t the same model.
5. Low interference
Bluetooth devices almost always avoid interference from other wireless devices. Bluetooth uses a technique known as frequency hopping, and also low power wireless signals.
6. Low energy consumption
As a result of Bluetooth using low power signals,
the technology requires very little energy and will use less battery or electrical power as a result. This is an excellent benefit for mobile devices, as Bluetooth won’t drain the battery.
7. Sharing voice and data The standard for Bluetooth will allow compatible devices to share data and voice communications. This is great for mobile phones and headsets, as Bluetooth simplifies driving and talking on your cell phone.
8. Instant PAN (Personal Area Network)
You can connect up to seven Bluetooth devices to each other within a range of up to 30 feet, forming a piconet or PAN. For a single room, you can also set up multiple piconets.
9. Upgradeable
Upgradeable is the standard for Bluetooth. There are newer versions of Bluetooth in the works, which offer many new advantages and backward compatible with older versions.
10. The technology stays
Bluetooth technology is a world wide, universal wireless standard. With it being as popular as it is, you can count on it being around for years to come. As more and more devices start to use Bluetooth technology, more manufacturers will be eager to make their products compatible. A chain reaction will occur, making Bluetooth the standard for cutting edge wireless.
Looking around on the World Wide Web, I found the article below about saving on International calling. Feel free to read it and shop around for cheap international calling plans. When you purchase a plan through Brochin.net, 100% of our commissions go to the Brothers in Arms Foundation.
by: Bob Graham
There are a variety of low cost international long distance calling products on the market today but each has been designed to fit the needs of a specific group of consumers. Marketers and product developers have tried to broaden the appeal of their products but all have certain limitations. The purpose of this article is to review categories of international calling products on the market today and provide a brief overview of their strengths and limitations so consumers can make better choices.
One product does not fit the needs of all. People who are PC savvy and have high speed INTERNET connections may choose to use PC to PC or PC to Phone service or VoIP technology while others may want the convenience and flexibility of a phone card. Most people only make occasional international calls while others make multiple international phone calls each day. Therefore, some people are willing to sacrifice quality and convenience in order to save money while others are willing to pay a bit more for higher quality, convenience and flexibility. Consumers need to understand the limitations of each product type so they can make informed choices.
• Traditional Long Distance – Forget using traditional long distance from your home phone, cell phone or office phone unless you only make one or two short international calls each year and you don’t care about wasting money. There are products on the market today which offer the same quality at a fraction of the cost.
• VoIP Phone Service – This may be a good option for saving money on home phone service but it is not the best option for saving money on international calls. There is a monthly charge for VoIP service and in most cases international long distance calls cost extra. The cost for making international long distance calls with VoIP is typically cheaper than the rates charged by traditional long distance providers but there cheaper options that are more convenient. A high speed internet connection is required for VoIP and most service providers require a long term contract. VoIP service providers typically charge extra fees for set-up, activation, early termination and some even charge for equipment.
• PC-to-PC or PC-to-Phone Service – This service is used to make calls over the internet from a personal computer. A PC-to-PC service like Skype is required along with equipment like a head-set and micro phone. PC-to-PC calls are typically free so this is a very cheap option but it is not very convenient since both parties need access to a PC and an internet connection. Calls can be made from PC-to-Phone but they are not free. This is more convenient but the caller still needs access to a PC and an internet connection. There are other methods for making international calls that cost about the same as PC-to-Phone but are more convenient and typically offer better quality.
• Phone Cards – Prepaid phone cards have ultimate convenience since they can be used to make cheap international calls from almost any phone (cell, home, business, pay phone or even VoIP). The cost for making international calls vary from being dirt cheap to expensive depending on the card used and the location or type of phone called. Calls to cell phones are generally more expensive than calls to land lines. Shopping and comparing phone cards can be complex because fee structures vary along with quality and usability. Most phone cards provide good rates to a few locations but poor rates to others. Shop for phone cards that offer good rates to the locations you call the most. Also, check for access number availability in the locations where you plan to use the phone card. Purchase phone cards from a reputable phone card supplier that fully discloses all fees and charges in an easy to understand format.
• Prepaid Long Distance – These are sometimes call dial-around plans. Prepaid long distance plans like Tel3Advantage are popular with frequent international callers since they offer a variety of useful features, low rates, high call quality and the convenience of a phone card. Tel3 Advantage also does not charge hidden fees or taxes so users actually pay the advertised rate for each call. Features include on-line account management, on-line call history with a complete record of each call, speed dial and PIN free dialing. Tel3 allows users to register up to 10 telephone numbers in each account. Calls made from these phone numbers can be made without dialing an account number or PIN code. Tel3Advantage has a wide network of local access numbers but can only be used to make calls from the USA and Canada.
• International Call Back Phone Service – This is a good method for making low cost international calls from almost any country. Many countries outside of North America, Europe and the developed countries in Asia have very high tariffs on international long distance calls. International callback long distance uses a clever method to avoid these tariffs by placing calls through long distance providers located in low cost third countries. There are at least three common methods used to trigger or place calls so potential users should conduct further research to determine the best method for their location and situation.
As summarized above, there are a variety of technologies available on the market today for making low cost international phone calls. Multiple companies’ market products using these technologies and some of these products are high quality and others are not. Consumers should shop and be smart about purchases. It is usually best to try a product by making a small purchase before making a large purchase or enter a long term contract. Most reputable VoIP providers will offer a 30 day (or longer) money back guarantee and most phone card providers will offer cards in small denominations so consumers can try the product before making a large purchase or commitment. It is best to stay away from those who don’t.
Protecting your computer from a virus is getting harder and harder each day. While it may border on the paranoid, it goes without saying that you can’t leave your guard down for one second. Even corporate giant Microsoft has found its own systems compromised on more than one occasion.
Remember the “good old days”, before the advent of the Internet and downloadable programs? Life was simple then in terms of computer viruses. With the primary way in which a virus could be transmitted being limited to floppy disks, the ability to catch and eradicate the virus was a lot easier. By today’s standards, it used to take quite a while before a virus was able to infect a computer and slow down the system. The antivirus software of that time was typically able to identify and eradicate viruses before they caused too much damage. Additionally, computer users were pretty savvy on how to protect themselves in terms of scanning all floppy disks before copying them to our desktop.
The Internet helped change all that. The Internet provided a conduit by which viruses could move from host to host with lightening speed. No longer could a computer user just worry about floppy disks as points of entry, but they now had to worry about email, email attachments, peer-to-peer file sharing, instant messaging, and software downloads. Today’s viruses can attack through multiple entry points, spread without human intervention, and take full advantage of vulnerabilities within a system or program. With technology advancing everyday, and the convergence of computers with other mobile devices, the potential of new types of threats also increase.
Protecting Your Computer
Luckily, the advancement of antivirus software has kept pace with current virus threats. Antivirus software is essential to a computer’s ability to fend off viruses and other malicious programs. These products are designed to protect against the ability of a virus to enter a computer through email, web browsers, file servers and desktops. Additionally, these programs offer a centralized control feature that handle deployment, configuration and updating.
A computer user should remain diligent and follow a few simple steps to protect against the threat of a virus:
1. Evaluate your current computer security system.
With the threat of a new generation of viruses able to attack in a multitude of ways, the approach of having just one antivirus software version has become outdated. You need to be confident that you have protected all aspects of your computer system from the desktop to the network, and from the gateway to the server. Consider a more comprehensive security system which includes several features including antivirus, firewall, content filtering, and intrusion detection. This type of system will make it more difficult for the virus to penetrate your system.
2. Only install antivirus software created by a well-known, reputable company.
Because new viruses erupt daily, it is important that you regularly update your antivirus software. Become familiar with the software’s real-time scan feature and configure it to start automatically each time you boot your computer. This will protect your system by automatically checking your computer each time it is powered up.
3. Make it a habit to always scan all new programs or files no matter from where they originate.
4. Exercise caution when opening binary, Word, or Excel documents of unknown sources especially if they were received during an online chat or as an attachment to an email.
5. Perform regular backups in case your system is corrupted. It may be the only way to recover your data if infected.
Recommended Antivirus Software
There are numerous applications available to consumers. With a little research, you can pick the program that is right for you. Many programs provide a trial version which allows you to download the program and test its abilities. However, be aware that some anti-virus programs can be difficult to uninstall. As a precaution make sure to set up a System Restore point before installing.
Here are a few programs which typically receive high marks in terms of cost, effectiveness, ease of use, and customer service.
The Shield Pro 2005™ provides virus protection and hacker security through ongoing support and updates. When a virus breaks out, The Shield Pro 2005™ promises to provide a patch within 2-3 hours and a fix for the virus within 5 hours. You can set your computer to update viruses weekly and run a complete virus scan.
BitDefender 9 Standard provides antivirus protection, as well as Peer-2-Peer Applications protection, full email protection, and heuristics in a virtual environment. This provides a new security layer that keeps the operating system safe from unknown viruses by detecting malicious pieces of code for which signatures have not been released yet.
Kaspersky Anti-Virus Personal 5.0 program is simple to install and use. The user only needs to choose from three levels of protection. It allows updates as frequently as every hour while promising not to disrupt your computer. The program also offers a two-tier email protection feature and round-the-clock technical support.
PC-cillin Internet Security combines antivirus security and a personal firewall—for comprehensive protection against viruses, worms, Trojans, and hackers. It also detects and removes spyware and blocks spam. It even guards against identity theft by blocking phishing and pharming attacks.
AVG Anti-Virus Free Edition is a free downloadable antivirus program that has received high marks for its reliability. In the past, free downloadable antivirus programs have been viewed skeptically because of issues relating to its reliability. However, AVG from Grisoft, remains one of the best-known free anti-virus programs available. While AVG can not be installed on a server operating system and there is no technical support, it still makes a good choice for many home computer users. The best part is that since it is free, you can try it with no further obligation necessary.

New computer viruses appear everyday to annoy us at the very least and worst case scenario, destroy the integrity and operation of our computers and networks.
In this post we provide information about the ten most prevalent viruses, as cited from around the web, in regards to how often they are seen and the likelihood they will cause damage to your systems.
Viruses are created daily and do not by any means take this a an all conclusive list, in fact, it is not even scratching the surface one bit. The fight against viruses and other Internet nasties is a never ending battle. You must remain vigilant, keep your security software updated daily and run scans regularly or all the time.
Virus: Trojan.Lodear
This virus is a Trojan horse that will install itself onto infected computers so it will start every time the system reboots. It will also try to download and install additional malware from a list of predetermined websites on the Internet. It does this by attempting to inject a .dll file into the EXPLORER.EXE process causing your system(s) to become unstable.
Virus: W32.Beagle.CO@mm A mass-mailing worm that lowers security settings. It can delete security-related registry sub keys and may block access to security-related websites.
Virus: Backdoor.Zagaban
A Trojan horse that allows the compromised computer to be used as a covert proxy and which may degrade network performance.
Virus: W32/Netsky-P A mass-mailing worm which spreads by emailing itself to addresses produced from files on the local drives.
Virus: W32/Mytob-GH A mass-mailing worm and IRC backdoor Trojan for the Windows platform. Messages sent by this worm will have the subject chosen randomly from a list including titles such as: Notice of account limitation, Email Account Suspension, Security measures, Members Support, Important Notification.
Virus: W32/Mytob-EX A mass-mailing worm and IRC backdoor Trojan similar in nature to W32-Mytob-GH. W32/Mytob-EX runs continuously in the background, providing a backdoor server which allows a remote intruder to gain access and control over the computer via IRC channels. This virus spreads by sending itself to email attachments harvested from your email addresses.
Virus: W32/Mytob-AS, Mytob-BE, Mytob-C, and Mytob-ER
This family of worm variationspossesses similar characteristics in terms of what they can do. They are mass-mailing worms with backdoor functionality that can be controlled through the Internet Relay Chat (IRC) network. Additionally, they can spread through email and through various operating system vulnerabilities such as the LSASS (MS04-011).
Virus: Zafi-D A mass mailing worm and a peer-to-peer worm which copies itself to the Windows system folder with the filename Norton Update.exe. It can then create a number of files in the Windows system folder with filenames consisting of 8 random characters and a DLL extension. W32/Zafi-D copies itself to folders with names containing share, upload, or music as ICQ 2005a new!.exe or winamp 5.7 new!.exe. W32/Zafi-D will also display a fake error message box with the caption “CRC: 04F6Bh” and the text “Error in packed file!”.
Virus: W32/Netsky-D A mass-mailing worm with IRC backdoor functionality which can also infect computers vulnerable to the LSASS (MS04-011) exploit.
Virus: W32/Zafi-B

Jun. 2004, Pécs (SNAF Team)”
For your safety, you really need to know about it and malicious plug-ins like it.
Have you experienced the below scenario? Many have.
You hit, possibly by mistake, what you thought was an Internet Explorer update option. The so called update option looks to be a pop-up that appears legitimate, but is not. In the end, it uploads a piece of malicious software called Intelligent Explorer or something similar on your computer. Now the nightmare begins!
Intelligent Explorer and programs like it allows software to be downloaded to your computer which causes a great deal of problems and can bring your computer to its knees or to a complete stop. Users can experience a myriad of problems like highly objectionable pop-up advertisements in the form of extreme pornography. It creates or changes your homepage and starts and endless loop of pop-up advertisements which can eventually, like stated previously, lock up your computer to a point you have to do a hard reboot. Trying to run a un-install will not work for this software.
What you will find even more amazing is the software licenses that people agree to when they download this malicious garbage. The license grants them the right to install software on your computer at will. The terms may read like the paragraph below:
“You grant to us the right, exercisable by us until you uninstall the Software or this agreement is otherwise terminated, to provide to you the Service of downloading and causing to be displayed advertising material on your computer, through ‘pop-up’ or other display while you use your browser. You acknowledge and agree that installation of the Software may automatically modify toolbars and other settings of your browser. By installing the Software you agree to such modifications.”

Internet users need to be aware of what they are downloading and not just arbitrarily click OK to the terms of service statements.
Researching in forums for help, you may find like the below:
” HELP!!! I HAVE A TROJAN, ADWARE OR SPYWARE INFECTING MY COMPUTER. I HAVE RUN A FEW DIFFERENT REMOVAL PROGRAMS FOR SPYWARE. ALL HAVE FOUND THE VIRUSES AND SAID THEY WERE REMOVED, BUT AS SOON AS I LOG INTO INTERNET EXPLORER, IT IS THERE AGAIN”
This is what you can do:
By a copy of MacAfee and Symantec’s latest anti-virus and anti-spyware software. However, there are freeware versions out there they should work just as well. Spybot S&D, Super Anti-Spyware and some others should do the trick, while keeping your money in your wallet.
Encryption and cryptographic software has been used in many different ways to make systems more secure. This article discusses only a few ways that such software can make your system more secure, including:
1) Encrypting your email
2) Encrypting your files
To programs are mentioned that will help encrypt information. There are many more programs out there that will help, but these programs are good and a good place to start as any. They have the added benefit of both being free with source code available.
Will encryption stop people from accessing my information?
Encryption simply makes it harder for people to gain access to important information, like passwords or sensitive information in a file. The first thing you should know about encryption is that the algorithm that is used to encrypt can be simple or more complex and that affects how securely what you have encrypted is protected. Encryption systems have been broken when the method of encryption is understood by hackers and is easy to break.
Why bother to encrypt my email?
It should be noted that email is far less secure than paper mail for two very good reasons: first, electronic data can be accessed easily over an Internet and secondly, electronic data is really simple to copy. There is a very good chance that someone has snooped around in your email despite your best intentions to stop it.
How do I go about encrypting my email?
There are many programs out there that can help you encrypt your email. A very popular one is PGP (Pretty Good Privacy) or its Gnu offshoot GPG.
PGP (http://www.pgpi.org/) self-describes itself this way: This “is a program that gives your electronic mail something that it otherwise doesn’t have: Privacy. It does this by encrypting your mail so that nobody but the intended person can read it. When encrypted, the message looks like a meaningless jumble of random characters. PGP has proven itself quite capable of resisting even the most sophisticated forms of analysis aimed at reading the encrypted text.”
Why bother to encrypt my files?
The answer to this boils down to what you store on your computer. If you have financial data with important information like social security numbers, email addresses, account numbers and passwords, then you open yourself up to losing very valuable information. Most corporate Internet security employees will attest to the widespread theft of very valuable information. As long as you are connected to the Internet you are vulnerable.
How do I go about encrypting my files?
AxCrypt File Encryption Software (http://axcrypt.sourceforge.net/) Self-described as “Free Personal Privacy and Security for Windows 98/ME/NT/2K/XP with AES-128 File Encryption, Compression and transparent Decrypt and Open in the original application.”
We will be pushing a few articles over the next couple weeks on computer security. You can bet that computer security in 2010 will be #1 priority in not only IT departments, but in the board rooms as well.
