In the early days of the Internet, traffic was usually measured in megabytes (MB) or gigabytes (GB).
Most web analysis software would look at the logs from a webserver and add up all the "bytes transferred" numbers and the dates and use that information to arrive at a total amount of traffic sent by that server in a given time period.
Some colocation providers continue to measure traffic this way, but most now use the 95th percentile metric. What is 95th percentile? What does it mean and how does it work? In this article, we'll try to briefly explain 95th percentile and the way it measures traffic in today's networks.
95th Percentile is a way to measure traffic that better fits with the way communications companies build their networks.
For example, if a customer will have peaks of 900Mb/s occasionally, but an average of only 50Mb/s, the telecommunications company still has to maintain network equipment capable of handling the 900Mb/s bursts even though the average usage is much less.
95th percentile is essentially a weighted average that is a fair way to balance the costs of handling the peak load while still giving the customer some accommodation for their lower average utilization.
Notice that the numbers are followed by "Mb" (lower case "b")? That's because 95th percentile is measuring megabits per second, not megabytes.
This is what is known as a rate-based metric since it measures rate and not volume. The normal way this is implemented is to take a sample of the data rate every 5 minutes, every day, all month long.
This will result in 8,640 samples per typical 30-day month.
At the end of the month we'll take the rate at which 95% of those samples fall at or below and we'll essentially "throw out" the highest 432 samples.
Another way to think of this is that you're effectively getting about 1.
5 days of "free" time and you're billed for the rate you're using the rest of the time.
Just remember that that "1.
5 days" is comprised of 432 individual 5-minute samples that can be scattered around any given month.
Most commercial facilities such as datacenters and telecommunications companies will bill for Internet usage using the 95th percentile metric.
There will usually be two components to the pricing, the first being the "committed" rate (what you buy by contract regardless of what you actually use), and the second being "overage" (what you use above the committed rate). For example, if you have a 10Mb/s commit on a burstable 100Mb/s circuit, you have the ability to burst up to 100Mb/s but overage above the 10Mb/s committed rate will be billed on 95th percentile at a per-megabit rate. Many times the burst rate is the same as the per-megabit committed rate but sometimes it will be less or even more. Be sure to check your contract when planning for bandwidth costs!

Know About What Is Psychology?
In simple words, psychology involves study of the human mind and how it functions in different situations.
In other words, basically it involves a deep analysis of how people think, behave and interact with one another in different type of situations and environments. This subject traces its roots to ancient civilizations of India, Egypt, China and Greece.
Wilhelm Wundt, a German Doctor is the person responsible for bringing psychology into lab settings and also introducing the structural school of psychology. After that many eminent researchers and analysts have contributed a lot in this field as it is never possible to read and predict the human mind in totality. Perhaps this is something that can change even before you may imagine.
That's the main beauty of this field because it deals with the most complex thing on the earth i.
e.
human mind. Various approaches to psychology include forensic, abnormal, computational, developmental, cognitive and quantitative psychology.
Psychologists make use of three types of inferences which are deduction, induction and abduction to provide explanations on the way the mind works.
As part of their efforts to understand the way the mind works, they make use of survey results. Surveys are used to record data which are needed to measure mood change patterns, attitude and traits, and other aspects of the human mind. A course in psychology usually covers a four year period, during which the student gets the opportunity to learn various aspects of the subject such as abnormal psychology, treatment for substance abuse, effective communication and much more.
As part of their learning curriculum they have to undertake various tests and handle different research projects.
It is to be noted that psychological studies are highly structured.
There are two main areas of focus, one is academic psychology and the other is applied psychology.
It focuses on various sub-topics in psychology and these include personality psychology, developmental and social psychology.
Applied psychology makes use of various types of psychological principles for resolving problems.
Industrial organizational and forensic psychology are examples of applied psychology.

SIDS - Risk Factors
SIDS or Sudden Infant Death Syndrome is a medical term which is diagnosed when an infant suddenly dies under unexplained circumstances after all known and possible causes have been carefully ruled out through autopsy, death scene investigation and review of the medical history.
This refers to children from birth or one month of age to one year of age.
In the USA 150,000 babies died from SIDS which means that 7,000 babies die each year and nearly one baby every hour of every day.
That makes SIDS responsible for more deaths than any other cause in childhood.
Families of all races, ethnic and socioeconomic origins are affected without warning because parents and physicians can't predict that something is going to happen because most SIDS victims appear healthy prior to death.
Below we give you specific risk factors that can be seen in research relating to SIDS for parents that have babies in a high-risk category.
SIDS risk factors: *Boys are more likely to die from SIDS.
*Young and inexperienced parents should increase their parental care. The highest risk is absence of support from family and friends and late or non regular parental care checks.
*All kinds of addictions (smoking, drinking alcohol and drugs) consider to be one of the main factors to SIDS.
*Premature born babies are at a high risk of SIDS because they are under developed and weak.
*Pregnant minors and women younger than 20 are at risk of having their baby die from SIDS due to their inexperience or unintentional neglect.
These risk factors don't cause SIDS but can have a negative effect on infant well-being. It is known that two thirds of SIDS victims have none of risk factors and that most infants with one or more of these risk factors will not die from SIDS.
There are many support groups for parents who have lost a child to SIDS which help them through the grieving process.
It is important to make yourself aware of these risk factors and take more care about safe sleeping to reduce a chance of losing a child to SIDS. There are some sleeping devices that should improve baby sleep safety, called baby sleep positioners.
Consult with a pediatrician if you should get one for your baby.

How to Select an Accredited Online College
Even though online degrees have made it possible for many people to pursue their dreams of a college education, it is still a wise decision to take the time to evaluate various online degrees and choose the program that is best for you.
Choosing the right distant learning university is one of the most important decisions you will have to make in your online education.
The success of your career depends on whether the online institution is accredited or not. There are a few very important questions you should ask before you enroll in any distant learning school.
Is This School Accredited? One of the first things to do is compile a list of online colleges and online universities that offer that online degree you are interested in.
Then, you want to check with the regional association that approves accreditation to institutions of higher learning. Make sure that your school is accredited by the correct regional association.
What is Accreditation? Accreditation ensures that a high standard of quality education has been met.
Accreditation from a reputable online institution also ensures that your online degree will be recognized by potential employers. Why is Accreditation so Important? As an online student, you need to understand the importance of getting a college degree from an accredited institution and the dangers of receiving a college degree from an institution without accreditation.
The internet is overcrowded with diploma mills and accreditation mills offering bogus or inauthentic accreditation. The federal government, USDE, and CHEA do not recognize accreditation from these outfits.
If the online institution is not properly accredited, your online degree may be a waste of time and money and will likely be rejected by employers.
How Important is Accreditation to Employers? Employers give preference to degrees that are earned through online institutions that have received their accreditation from one of the reputable accrediting agencies over degrees that are not accredited.
As a matter of fact, most employers may reject a degree that is not accredited and this can hurt your chances for career mobility and future employment.
What Accredited Online Degrees Are Offered? Not every program offers every degree that is accredited.
Before you enroll, make sure that your school offers the accredited online degree that you are looking for.
How Long Has This University Existed? The longer the school has existed, the better.
The best online colleges and institutions have been in existence for a long time and have an excellent accreditation standing.
Many started out at traditional schools and added online programs to their offerings or started an entire online school to run in tandem with the physical college or university.
With so many online degrees and online institutions to choose from, it is important to do diligent research on the background of the institution offering the degree before making your selection.
In the end, it is critical that you select the one that is accredited and is most suitable for your needs.

5 Tips For Removing Stains on Children's Clothing
Children's clothing can get extremely dirty and the stains can be quite stubborn to remove.
But with these five, proven tips, removing stains from children's clothing will be quite effortless. 1.
Use Pre-Wash Stain Remover While some parents may know of this method, many are unaware of the technique. Using a pre-wash stain remover for either small or large spot stains is a near guaranteed way to get out nearly every type of stain on clothing imaginable, including red ink and even protein-rich blood stains. But the key is to vigorously rub it in with a soft, gentle cloth and then let it sit and soak in for at least ten to fifteen minutes before tossing the clothes into the washing machine.
2. Use Drop of Dishwashing Detergent Dishwashing detergent dissolves all types of grease, oils and other substances much better than laundry detergent. It's strong so it's only necessary to put in a little bit into the wash water.
It will help lift off the worse stains imaginable and won't bubble up or clog the machine the way adding much more laundry detergent does when it foams up when too much is added.
It's not necessary to rub it into the stains.
Just add it to the water.
3. Soak Clothes Overnight Before Washing This technique is a definite way to eliminate nearly every stain in kid's clothing.
Take a separate wash basin and add hot water and a half to full scoop of laundry detergent without any bleach even if the clothes are white.
Rinse the clothes around by hand until the soiled garment is fully soaked and wet. Then simply allow it to sit in the water-detergent mixture for 24 hours and then put it into a hot water wash with fresh laundry detergent added to the load. 4. Incorporate Baking Soda into the Wash Cycle Baking soda will work wonders as it enhances the stain and cleaning removal process of standard laundry detergent.
It will give a fizzy and bubbly appearance in the wash water but that's okay because that means it's cleaning the soiled fabric the way it should, Baking soda is exceptional in its ability to lift off caked on and oily stains because of it's natural and superior cleansing power not found in standard laundry detergents or even bleach. 5. Add A Sprinkle of Salt if Bleach Doesn't Work If adding bleach to whites doesn't work, try the old hard water technique by sprinkling in a teaspoon of salt. The abrasiveness of the salt when it breaks down in the wash cycle will lift out stains as superbly as anything of its kind.
And the best thing about salt is that it doesn't damage clothes at all.
In fact, it actually strengthens most fibres that children commonly wear.

How to Make Good Grades in School
Studying is not such an easy task.
Sometimes, even a "B" becomes unattainable. How much more do you need to study to receive an "A"? Even if all cynics on studying hard would say that everything about school is difficult, it is not impossible to make good grades in school as long as you follow these simple solutions.
All it takes is the discipline you would impose on yourself. You must listen attentively to your teachers. It is undeniable that there are a lot of temptations once you step out of school, and even though you know there is a quiz the following day, you might end up loitering at the mall instead of studying.
But if you have listened to the classroom discussion, you will be able to answer the quiz.
So if you want to have some extra time at the mall, listen to your professor and refrain from talking.
You should find time to do your homework and other projects.
Your homework is an essential part of your grade and failing to submit one would affect your grade.
So when you reach home, grab your pen and paper before turning on the television. It would save you from getting a low grade and some electricity as well. It's not bad to watch television but you have to prioritize your homework and school projects. Reading should be inculcated into your being. At times that you feel like you don't have anything to do, just grab a book and read.
It sharpens your brain and aids in fast comprehension.
You get to expand your knowledge if you read materials that present worthwhile and significant information about different subject areas that you deal with in school.
The most important thing by far is discipline.
In fact, this is the key to get good grades in school. Who knows, you might get an "A" after all?
