Ever wondered what is a virus....? check this out...

A computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user. However, the term "virus" is commonly used, albeit erroneously, to refer to many different types of malware programs. The original virus may modify the copies, or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or the Internet, or by carrying it on a removable medium such as a floppy disk, CD, or USB drive. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A worm can spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a file that appears harmless until executed.

Many personal computers are now connected to the Internet and to local area networks, facilitating the spread of malicious code. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative terminology in which a virus is any form of self-replicating malware.

Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply replicate themselves and perhaps make their presence known by presenting text, video, or audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by legitimate programs. As a result, they often cause erratic behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.

Find out who's invisible on yahoo messenger.....

Chose a person you want to check .Double click to open the chat window.Now simply invite the person for a voice conference.This is done by clicking on the "conference' button on the top of the chat window.
If the talk button appears and turns green then that person is online.But if you receive the message 'Voice chat could not be started ' then the person is offline.

Note:Some people use softwares like buddy spy to check who is invisible.I DON'T RECOMMEND you to use such third party softwares as they can expose your PC to hackers by sending your personal information and can even steal information from your PC.So avoid such softwares and instead use the simple tricks given above.

What is Voip....?

What Is VoIP? and How Does It Work?
Introduction....

The way we make phone calls is changing. In fact in many circumstances things have already changed. Take long distance calls for instance, many service providers are already using a technology called Voice Over IP or VOIP for short. If you have never heard of VOIP before, then the following article will change the way you think about how long distance phone calls are being made now, and about how all phone calls will be made in the future. Voice Over IP (VOIP) is a method for turning analogue audio signals into digital data that can be transferred over the Internet.

You may be asking yourself how this is useful. Well think about it for a few seconds. If it is possible to turn analogue signals into digital data, then VOIP can turn a standard Internet connection into a method for placing phone calls anywhere in the world virtually free, except for your Internet service fee, enabling you to bypass the phone companies entirely.

Voice Over IP (VOIP) has the potential to completely revolutionise the way the worlds phone systems operate. There are many VOIP service providers that have been around for a while, and are growing steadily. Now the worlds leading telecommunications operators are waking up to the endless possibilities of this new technology, setting up VOIP calling centres around the world and promoting the sales of Voice Over IP phone systems. Read more information:

Making a call

With VOIP phone systems it is possible to make a call in one of three ways:

ATA (gateway) ? The simplest way to make a VOIP phone call is through the use of ATA's (analogue telephone adaptor) sometimes called gateways. These devices enable you to make use of your existing standard analogue phones. You simply plug your standard handset into the ATA (gateway) then connect the ATA to your computer or your Internet connection, enabling you to make VOIP calls. An ATA takes the analogue signal from your standard phone and turns it into a digital signal that ready for transmission over the Internet. Some ATA's (gateways) come with additional software that is loaded onto a host computer, enabling you to configure it for VOIP accurately.



IP Phones ? These handsets look just like normal standard handsets. They have an RJ 45 Ethernet connector instead of the standard RJ 11 connectors. These phones have all the necessary software and hardware to handle VOIP calls already built in them. They connect directly to your router, providing a very fast and cost effective entry into the world of Voice Over IP.



Computer to computer ? This is the easiest way to make use of the VOIP technology. There are many companies offering cost effective software that you can use for this type of VOIP. Usually the only charge you pay is the monthly one from your Internet service provider, even for long distance calls. All you need is a microphone, speakers, a suitable sound card and a fast Internet connection.

Chances are that you have already made a VOIP call without even realising it. The major phone companies already use VOIP to route thousands of long distance calls through a circuit switch and into an IP gateway. This is then received by a gateway at the other end and then routed to another local circuit switch. More and more companies are installing VOIP phone systems, and the technology will grow and grow until it finds its way into every business and household across the globe.Read more information:

Do U want to recover Ur scratched cd's....try the things given below...

Recover Your Scratched CD

Every one has had trouble with a scratched CD. Scratched data CD can't be read properly and in case of audio CD ,the CD skips when we play it.

The first thing to do with a CD which gives a reading error, is to clean it; to check that the error is not being caused by a dirty surface. You can try cleaning the CD with a soft cotton cloth by wiping its surface . Start at the center and rub gently straight outward towards the edge. In case of a stubborn stain,you can try using warm water with some mild soap.Avoid sponges since they can scratch the CD.

A CD's data is recorded on a metal layer inside it. This metal layer is inset in a transparent plastic covering (polycarbonate) which is used to protect the CD's metal layer and to allow printing a label on the side not used for reading.

A CD-ROM drive uses a laser beam to read the metal layer. This laser beam crosses the plastic layer and reads the metal layer. If the plastic layer is scratched, the beam will be unable to pass through it as it will get deviated, resulting in a read error. The data to be read still lies in the CD, the trouble lies in the layer of plastic.


So how to repair this CD which holds your favourite Elvis Presly track?

As the CD's contents are preserved, a scratched CD can be recovered by polishing its plastic surface.
The aim is to make the laser beam reach the metal surface which holds the data, in a straight line, without any deviations and change in intensity which may otherwise arise in a scratched CD.



Try polishing your CD with a "toothpaste"(baking soda toothpaste).Polish the scratches with a cotton swab. Rub gently the paste-imbued swab over the scratches until they disappear or until you notice that you have removed them as far as possible.Do all the cleaning gently.Do not apply pressure.After clearing the scratches, wash the CD in water.Let the water evaporate by itself.Do not keep the CD in sunlight.Keep it in a cool and shady area.

DO NOT USE A GEL TOOTHPASTE.

If the scratches still persist try using a metal polish (Brasso) in the same way as described above. Rub Vaseline on the CD, very gently (do not press hard).Rub from the centre to the rim. Wipe excess off using clean, soft, lint-free cloth in a radial (inside to outside) motion.
Test disc again. If the Vaseline does the trick, burn a new copy of the CD immediately. The Vaseline method is only a temporary solution.

NTFS V/s FAT check this..

NTFS vs FAT
To
NTFS or not to NTFS—that is the question. But unlike the deeper
questions of life, this one isn't really all that hard to answer. For
most users running Windows XP, NTFS is the obvious choice. It's more
powerful and offers security advantages not found in the other file
systems. But let's go over the differences among the files systems so
we're all clear about the choice. There are essentially three different
file systems available in Windows XP: FAT16, short for File Allocation
Table, FAT32, and NTFS, short for NT File System.

FAT16

The FAT16 file system was introduced way back with MS–DOS in 1981, and
it's showing its age. It was designed originally to handle files on a
floppy drive, and has had minor modifications over the years so it can
handle hard disks, and even file names longer than the original
limitation of 8.3 characters, but it's still the lowest common
denominator. The biggest advantage of FAT16 is that it is compatible
across a wide variety of operating systems, including Windows 95/98/Me,
OS/2, Linux, and some versions of UNIX. The biggest problem of FAT16 is
that it has a fixed maximum number of clusters per partition, so as
hard disks get bigger and bigger, the size of each cluster has to get
larger. In a 2–GB partition, each cluster is 32 kilobytes, meaning that
even the smallest file on the partition will take up 32 KB of space.
FAT16 also doesn't support compression, encryption, or advanced
security using access control lists.

FAT32

The FAT32 file system, originally introduced in Windows 95 Service Pack
2, is really just an extension of the original FAT16 file system that
provides for a much larger number of clusters per partition. As such,
it greatly improves the overall disk utilization when compared to a
FAT16 file system. However, FAT32 shares all of the other limitations
of FAT16, and adds an important additional limitation—many operating
systems that can recognize FAT16 will not work with FAT32—most notably
Windows NT, but also Linux and UNIX as well. Now this isn't a problem
if you're running FAT32 on a Windows XP computer and sharing your drive
out to other computers on your network—they don't need to know (and
generally don't really care) what your underlying file system is.

The Advantages of NTFS

The NTFS file system, introduced with first version of Windows NT, is a
completely different file system from FAT. It provides for greatly
increased security, file–by–file compression, quotas, and even
encryption. It is the default file system for new installations of
Windows XP, and if you're doing an upgrade from a previous version of
Windows, you'll be asked if you want to convert your existing file
systems to NTFS. Don't worry. If you've already upgraded to Windows XP
and didn't do the conversion then, it's not a problem. You can convert
FAT16 or FAT32 volumes to NTFS at any point. Just remember that you
can't easily go back to FAT or FAT32 (without reformatting the drive or
partition), not that I think you'll want to.

The
NTFS file system is generally not compatible with other operating
systems installed on the same computer, nor is it available when you've
booted a computer from a floppy disk. For this reason, many system
administrators, myself included, used to recommend that users format at
least a small partition at the beginning of their main hard disk as
FAT. This partition provided a place to store emergency recovery tools
or special drivers needed for reinstallation, and was a mechanism for
digging yourself out of the hole you'd just dug into. But with the
enhanced recovery abilities built into Windows XP (more on that in a
future column), I don't think it's necessary or desirable to create
that initial FAT partition.

When to Use FAT or FAT32

If you're running more than one operating system on a single computer,
you will definitely need to format some of your volumes as FAT. Any
programs or data that need to be accessed by more than one operating
system on that computer should be stored on a FAT16 or possibly FAT32
volume. But keep in mind that you have no security for data on a FAT16
or FAT32 volume—any one with access to the computer can read, change,
or even delete any file that is stored on a FAT16 or FAT32 partition.
In many cases, this is even possible over a network. So do not store
sensitive files on drives or partitions formatted with FAT file systems.

However, you are on thin ice here! The interviewer could be checking your honesty. On the other hand, he/she may also be trying to find out how focused you are - are you applying randomly, or is there a well-planned strategy?

Whatever your answer, it should match your career goals.

What Is Your Job Profile In the Current Job?

The interviewer is trying to find out if your experience can help the company ? if you have the relevant skills or not! While answering this type of a question, give all details about your job profile, and also mention any special skills that you imparted to the job.

What Salary Are You Drawing?

The question is not difficult to answer ? just be honest and give the figure. In all probability, your next employer may base your salary on this amount. However, the problem arises when you feel you are being underpaid in your current organisation. You may feel tempted to lie, but do not give in, as checks can be easily made and you may be disqualified. In case you are getting additional perks, incentives or commissions, do not forget to mention them, as they are important while negotiating salary.

What Salary Are You Expecting?

Try not to get into salary details early in the interview. If pressed, you could say that it all depends on the job, and would like to talk about it after a job offer. Say this in a convincing tone. In case you are asked this question in your latter interviews, give a direct answer. Do not sound apologetic while quoting the figure you have in mind.

Sugar Harmful...confused...check this out..

The Harmful Effects Of Sugar On Mind And Body
Of all the foods consumed today, refined sugar is considered to be one of the most harmful. ...In 1997 Americans devoured 7.3 billion pounds of candy. Americans spent an estimated $23.1 billion dollars on candy and gum. The average American consumed a record 27.3 pounds of candy and gum in the same year-the equivalent of about six regular sized chocolate bars a week-marking the fifth consecutive year of increased demand. (1) ...Consumption of processed foods (which are laced with sugar) cost the American public more than $54 billion in dental bills each year, so the dental industry reaps huge profits from the programmed addiction of the public to sugar products. ...Today we have a nation that is addicted to sugar. In 1915, the national average of sugar consumption (per year) was around 15 to 20 pounds per person. Today the average person consumes his/her weight in sugar, plus over 20 pounds of corn syrup. To add more horrors to these facts there are some people that use no sweets and some who use much less than the average figure, which means that there is a percentage of the population that consume a great deal more refined sugar than their body weight. The human body cannot tolerate this large amount of refined carbohydrates. The vital organs in the body are actually damaged by this gross intake of sugar.

...Refined sugar contains no fiber, no minerals, no proteins, no fats, no enzymes, only empty calories. What happens when you eat a refined carbohydrate like sugar? Your body must borrow vital nutrients from healthy cells to metabolize the incomplete food. Calcium, sodium, potassium and magnesium are taken from various parts of the body to make use of the sugar. Many times, so much calcium is used to neutralize the effects of sugar that the bones become osteoporotic due to the withdrawn calcium. Likewise, the teeth are affected and they lose their components until decay occurs and hastens their loss. ...Refined sugar is void of all nutrients, consequently it causes the body to deplete its own stores of various vitamins, minerals and enzymes. If sugar consumption is continued, an over-acid condition results, and more minerals are needed from deep in the body to correct the imbalance. If the body is lacking the nutrients used to metabolize sugar, it will not be able to properly handle and rid itself of the poisonous residues. These wastes accumulate through the brain and nervous system, which speeds up cellular death. The bloodstream becomes over-loaded with waste products and symptoms of carbonic poisoning result.

15 Tips for Writing Successful Resumes

The thought of writing a resume intimidates almost anyone. It's difficult to know where to start or what to include. It can seem like an insurmountable task. Here are 15 tips to help you not only tackle the task, but also write a winning resume.

1.Determine your job search objective prior to writing the resume. Once you have determined your objective, you can structure the content of your resume around that objective. Think of your objective as the bull's-eye to focus your resume on hitting. If you write your resume without having a clear objective in mind, it will likely come across as unfocused to those that read it. Take the time before you start your resume to form a clear objective.

2. Think of your resume as a marketing tool. Think of yourself as a product, potential employers as your customers, and your resume as a brochure about you. Market yourself through your resume. What are your features and benefits? What makes you unique? Make sure to convey this information in your resume.

3. Use your resume to obtain an interview, not a job. You don't need to go into detail about every accomplishment. Strive to be clear and concise. The purpose of your resume is to generate enough interest in you to have an employer contact you for an interview. Use the interview to provide a more detailed explanation of your accomplishments and to land a job offer.
4. Use bulleted sentences. In the body of your resume, use bullets with short sentences rather than lengthy paragraphs. Resumes are read quickly. This bulleted sentence format makes it easier for someone to quickly scan your resume and still absorb it.

5. Use action words. Action words cause your resume to pop. To add life to your resume, use bulleted sentences that begin with action words like prepared, developed, monitored, and presented.

6.Use #'s, $'s and %'s. Numbers, dollars, and percentages stand out in the body of a resume. Use them. Here are two examples:
· Managed a department of 10 with a budget of $1,000,000.
· Increased sales by 25% in a 15-state territory.

7.Lead with your strengths. Since resumes are typically reviewed in 30 seconds, take the time to determine which bullets most strongly support your job search objective. Put those strong points first where they are more apt to be read.

8. Play Match Game. Review want ads for positions that interest you. Use the key words listed in these ads to match them to bullets in your r

9.Use buzzwords. If there are terms that show your competence in a particular field, use them in your resume. For marketing people, use "competitive analysis." For accounting types, use "reconciled accounts."

10. Accent the positive. Leave off negatives and irrelevant points. If you feel your date of graduation will subject you to age discrimination, leave the date off your resume. If you do some duties in your current job that don't support your job search objective, leave them off your resume. Focus on the duties that do support your objective. Leave off irrelevant personal information like your height and weight.

11.Show what you know. Rather than going into depth in one area, use your resume to highlight your breadth of knowledge. Use an interview to provide more detail.

12. Show who you know. If you have reported to someone important such as a vice president or department manager, say so in your resume. Having reported to someone important causes the reader to infer that you are important.

13. Construct your resume to read easily. Leave white space. Use a font size no smaller than 10 point. Limit the length of your resume to 1-2 pages. Remember, resumes are reviewed quickly. Help the reader to scan your resume efficiently and effectively.

14. Have someone else review your resume. Since you are so close to your situation, it can be difficult for you to hit all your high points and clearly convey all your accomplishments. Have someone review your job search objective, your resume, and listings of positions that interest you. Encourage them to ask questions. Their questions can help you to discover items you inadvertently left off your resume. Revise your resume to include these items. Their questions can also point to items on your resume that are confusing to the reader. Clarify your resume based on this input.

15. Submit your resume to potential employers. Have the courage to submit your resume. Think of it as a game where your odds of winning increase with every resume you submit. You really do increase your odds with every resume you submit. Use a three-tiered approach. Apply for some jobs that appear to be beneath you. Perhaps they will turn out to be more than they appeared to be once you interview for them. Or perhaps once you have your foot in the door you can learn of other opportunities. Apply for jobs that seem to be just at your level. You will get interviews for some of those jobs. See how each job stacks up. Try for some jobs that seem like a stretch. That's how you grow -- by taking risks. Don't rule yourself out. Trust the process. All the best in your job search! esume. If you have missed any key words, add them to your resume.
