Details About WWW

What is the Web?

The World Wide Web is like a huge electronic magazine with its pages stored on many computers (called "servers") around the world. Pages on the web are connected by links called "hypertext". Each hypertext link jumps to another page... so unlike reading a book where one page follows another in sequence, on the World Wide Web you follow a web of links to visit the information your are interested in.

What is termed "surfing the web" is clicking through one page to another - from hypertext link to hypertext link. You can go on an endless adventure from web page to web page, turning back at any time, or going off in tangents.

To access the World Wide Web you need, a computer, a modem (or some other connection device), a phone line, and software called a "browser"... and an account with an Internet Service Provider. The browser itself is a relatively simple piece of software that interprets a computer code called HTML - or hypertext mark-up language. Most web pages are written in HTML - the browser merely interprets the HTML's instructions to display the text, pictures, play sounds or run animation. The two most popular browsers are Firefox and Microsoft's Internet Explorer.

The term WWW refers to the World Wide Web or simply the Web. The World Wide Web consists of all the public Web sites connected to the Internet worldwide, including the client devices (such as computers and cell phones) that access Web content. The WWW is just one of many applications of the Internet and computer networks.

The World Web is based on these technologies:

    HTML - Hypertext Markup Language

Researcher Tim Berners-Lee led the development of the original World Wide Web in the late 1980s and early 1990s. He helped build prototypes of the above Web technologies and coined the term "WWW." Web sites and Web browsing exploded in popularity during the mid-1990s.

What is Cloud Computing?


Cloud computing is a topic that many find confusing. It isn’t, though, as confusing as it sounds. In fact, most of those who claim not to understand the subject are part of the majority that use it daily.

In basic terms, cloud computing is the phrase used to describe different scenarios in which computing resource is delivered as a service over a network connection (usually, this is the internet). Cloud computing is therefore a type of computing that relies on sharing a pool of physical and/or virtual resources, rather than deploying local or personal hardware and software. It is somewhat synonymous with the term ‘utility computing’ as users are able to tap into a supply of computing resource rather than manage the equipment needed to generate it themselves; much in the same way as a consumer tapping into the national electricity supply, instead of running their own generator.

One of the key characteristics of cloud computing is the flexibility that it offers and one of the ways that flexibility is offered is through scalability. This refers to the ability of a system to adapt and scale to changes in workload. Cloud technology allows for the automatic provision and deprovision of resource as and when it is necessary, thus ensuring that the level of resource available is as closely matched to current demand as possible. This is a defining characteristic that differentiates it from other computing models where resource is delivered in blocks (e.g., individual servers, downloaded software applications), usually with fixed capacities and upfront costs. With cloud computing, the end user usually pays only for the resource they use and so avoids the inefficiencies and expense of any unused capacity.

However, the advantages of cloud computing are not limited to flexibility. Enterprise can also benefit (in varying degrees) from the economies of scale created by setting up services en masse with the same computing environments, and the reliability of physically hosting services across multiple servers where individual system failures do not affect the continuity of the service.

There is also great choice in the level of security and management required in cloud deployments, with an option to suit almost any business:

A public cloud, for example, is a cloud in which services and infrastructure are hosted off-site by a cloud provider, shared across their client base and accessed by these clients via public networks such as the internet. Public clouds offer great economies of scale and redundancy but are more vulnerable than private cloud setups due their high levels of accessibility. More information can be found on our ‘What is a Public Cloud?’ page.

Private clouds on the other hand use pooled services and infrastructure stored and maintained on a private network – whether physical or virtual – accessible for only one client. The obvious benefits to this are greater levels of security and control.  Cost benefits must be sacrificed to some extent though, as the enterprise in question will have to purchase/rent and maintain all the necessary software and hardware. More information can be found on our ‘What is a Private Cloud?’ page.

Over the last few years clouds have become the buzzword in computing. But ask someone what cloud computing is and they’re likely to give you a very different answer to the person standing next to them.

Like clouds themselves, the definition of cloud computing is currently a little fuzzy.

Today cloud computing covers anything that involves delivering hosted services over the internet. These services are generally divided into three categories: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (PaaS) and Software-as-a-Service (SaaS).

Clouds are owned by large single parties such as individual companies and are usually used by small to medium commercial businesses and researchers. These users normally pay the provider to use their computing resources.

The name cloud computing came from the cloud symbol that is frequently used to represent the Internet in diagrams and flowcharts.

All cloud services have three unique characteristics that distinguish them from traditional hosting:

    They are commercial and sold on demand to users
    They are flexible - a user can have as little or as much of the service as he wants at any time and can quickly outsource peaks of activity without long term commitment
    They are fully managed by the cloud provider; the consumer requires only a computer and internet access.

How to Keep Your Skin Fresh at Summer


Summer Skincare Essentials

With the guidance of sagely beauty blogger, Suzie, we go over skincare tips to keep in mind when transitioning your beauty routine from spring to summer. Remember, ladies, a chance in temperature also means a change in your routine as the hot weather and sun’s rays will damage your skin faster than you can say, “Pool party!”

Sure, relaxing by the beach is fun, but what about on days when all you want to do is pamper yourself in the comfort of your own home? With this Bath Salt Making Kit from Grow & Make, you can create your own personal blend of bath salts, and enjoy them all without leaving your home! Long live summer!

You  may think summer is the perfect time to ditch your moisturizer since, hey, you’ll be sweating buckets and in places you’ve probably never sweat before, but don’t! That’s a common misconception as your skin still needs to be hydrated and moisturized during the summer season. Remember, dry skin will only get drier if you’re not moisturizing, but continually sweating.

How to Keep your Eyes Healthy


Eat Right to Improve Your Sight
The eyes are vascular, so a heart-healthy diet that’s low in trans and saturated fat is important to keep the blood vessels of the eyes healthy. Foods rich in antioxidants are also known to help protect the eyes from age-related macular degeneration (ARMD), which is the leading cause of blindness among older Americans; as well as cataracts and other eye-related conditions. In the Age-Related Eye Disease Study (AREDS), subjects who supplemented their diet with Vitamin C, antioxidants, zinc, beta-carotene, and vitamin E experienced about a 25% reduction in risk of developing serious ARMD.

Here are seven foods help you see clearly.

You've probably heard that carrots and other orange-colored fruits and vegetables promote eye health and protect vision, and it's true: Beta-carotene, a type of vitamin A that gives these foods their orange hue, helps the retina and other parts of the eye to function smoothly.

But eating your way to good eyesight isn't only about beta-carotene. Though their connection to vision isn't as well-known, several other vitamins and minerals are essential for healthy eyes. Make these five foods a staple of your diet to keep your peepers in tip-top shape.

Do You Know The Meaning & Functions of Search Engines ?

A search engine is a web-based tool that enables users to locate information on the World Wide Web. Popular examples of search engines are Google, Yahoo!, and MSN Search. Search engines utilize automated software applications (referred to as robots, bots, or spiders) that travel along the Web, following links from page to page, site to site. The information gathered by the spiders is used to create a searchable index of the Web.


A search engine is a software program or script available through the Internet that searches documents and files for keywords and returns the results of any files containing those keywords. Today, there are thousands of different search engines available on the Internet, each with their own abilities and features. The first search engine ever developed is considered Archie, which was used to search for FTP files and the first text-based search engine is considered Veronica. Today, the most popular and well known search engine is Google.

Because large search engines contain millions and sometimes billions of pages, many search engines not only just search the pages but also display the results depending upon their importance. This importance is commonly determined by using various algorithms.

How do search engines work?

Every search engine uses different complex mathematical formulas to generate search results. The results for a specific query are then displayed on the SERP. Search engine algorithms take the key elements of a web page, including the page title, content and keyword density, and come up with a ranking for where to place the results on the pages. Each search engine’s algorithm is unique, so a top ranking on Yahoo! does not guarantee a prominent ranking on Google, and vice versa. To make things more complicated, the algorithms used by search engines are not only closely guarded secrets, they are also constantly undergoing modification and revision. This means that the criteria to best optimize a site with must be surmised through observation, as well as trial and error — and not just once, but continuously.

Gimmicks less reputable SEO firms tout as the answer to better site rankings may work at best for only a short period before the search engine’s developers become wise to the tactics and change their algorithm. More likely, sites using these tricks will be labeled as spam by the search engines and their rankings will plummet.

Search engines only “see” the text on web pages, and use the underlying HTML structure to determine relevance. Large photos, or dynamic Flash animation mean nothing to search engines, but the actual text on your pages does. It is difficult to build a Flash site that is as friendly to search engines; as a result, Flash sites will tend not to rank as high as sites developed with well coded HTML and CSS (Cascading Style Sheets — a complex mechanism for adding styles to website pages above and beyond regular HTML). If the terms you want to be found by do not appear in the text of your website, it will be very difficult for your website to yield high placement in the SERPs.

How to Speak English and Become a Good Speaker ?


1. Don't study grammar too much
This rule might sound strange to many ESL students, but it is one of the most important rules. If you want to pass examinations, then study grammar. However, if you want to become fluent in English, then you should try to learn English without studying the grammar.

Studying grammar will only slow you down and confuse you. You will think about the rules when creating sentences instead of naturally saying a sentence like a native. Remember that only a small fraction of English speakers know more than 20% of all the grammar rules. Many ESL students know more grammar than native speakers. I can confidently say this with experience. I am a native English speaker, majored in English Literature, and have been teaching English for more than 10 years. However, many of my students know more details about English grammar than I do. I can easily look up the definition and apply it, but I don't know it off the top of my head.

I often ask my native English friends some grammar questions, and only a few of them know the correct answer. However, they are fluent in English and can read, speak, listen, and communicate effectively.

Do you want to be able to recite the definition of a causative verb, or do you want to be able to speak English fluently?

2. Learn and study phrases
Many students learn vocabulary and try to put many words together to create a proper sentence. It amazes me how many words some of my students know, but they cannot create a proper sentence. The reason is because they didn't study phrases. When children learn a language, they learn both words and phrases together. Likewise, you need to study and learn phrases.

If you know 1000 words, you might not be able to say one correct sentence. But if you know 1 phrase, you can make hundreds of correct sentences. If you know 100 phrases, you will be surprised at how many correct sentences you will be able to say. Finally, when you know only a 1000 phrases, you will be almost a fluent English speaker.

The English Speaking Basics section is a great example of making numerous sentences with a single phrase. So don't spend hours and hours learning many different words. Use that time to study phrases instead and you will be closer to English fluency.

Don't translate

When you want to create an English sentence, do not translate the words from your Mother tongue. The order of words is probably completely different and you will be both slow and incorrect by doing this. Instead, learn phrases and sentences so you don't have to think about the words you are saying. It should be automatic.

Another problem with translating is that you will be trying to incorporate grammar rules that you have learned. Translating and thinking about the grammar to create English sentences is incorrect and should be avoided.

3. Reading and Listening is NOT enough. Practice Speaking what you hear!
Reading, listening, and speaking are the most important aspects of any language. The same is true for English. However, speaking is the only requirement to be fluent. It is normal for babies and children to learn speaking first, become fluent, then start reading, then writing. So the natural order is listening, speaking, reading, then writing.

First Problem
Isn't it strange that schools across the world teach reading first, then writing, then listening, and finally speaking? Although it is different, the main reason is because when you learn a second language, you need to read material to understand and learn it. So even though the natural order is listening, speaking, reading, then writing, the order for ESL students is reading, listening, speaking, then writing.

Second Problem
The reason many people can read and listen is because that's all they practice. But in order to speak English fluently, you need to practice speaking. Don't stop at the listening portion, and when you study, don't just listen. Speak out loud the material you are listening to and practice what you hear. Practice speaking out loud until your mouth and brain can do it without any effort. By doing so, you will be able to speak English fluently.

4. Submerge yourself
Being able to speak a language is not related to how smart you are. Anyone can learn how to speak any language. This is a proven fact by everyone in the world. Everyone can speak at least one language. Whether you are intelligent, or lacking some brain power, you are able to speak one language.

Many have said that the English language is one of the hardest to learn. However, with the right training, learning English as a second language can be a fun and positive experience. In this article you will better understand how to tackle the English language and how to speak English fluently.

One mistake that people often make is putting in effort to study grammar rather than conversational English. In order to become a good English speaker, remember to focus on actually conversing rather than just memorizing grammatical rules. To speak good English you need to focus on conversing!

Also remember to LISTEN! Sometimes, you can begin to understand other people before actually being able to speak fluently yourself. This is a step in the right direction. Being able to understand others will help in forming conversation yourself. Be sure to completely immerse yourself in the language. If you continue to limit yourself to social circles that do not speak English, it will make fluency that much more difficult. By submerging yourself in the language you will be forced to learn and use the English language.

Another tip is to not translate each and every word or phrase that you hear. Often you will misunderstand the topic of conversation by taking the most literal translation of each phrase. As in every language, English speakers often revert to slang and cliches. Don't be afraid to ask what these mean, by understanding these phrases you will be that much closer to fluency and on your way to being able to speak correct English.

Listen to the sound of your own voice.

Even though you might not like hearing your own voice, this is a very useful way to find out what's wrong with your spoken English. Record yourself speaking and then listen to the tape, or ask a native speaker for some advice.
Keep a talking journal.

Record your thoughts in English before you go to sleep at night. You can play the tape at the end of the year to look back on important events, as well as monitor your English progress.
Take extra classes.

How to Be Maintain Good Health

More and more research is showing that the key to lifelong good health is what experts call “lifestyle medicine” — making simple changes in diet, exercise and stress management. To help you turn that knowledge into results, we’ve put together this manageable list of health and wellness action steps.

We asked three experts — a naturopathic physician, a nutritionist, and a personal trainer — to tell us the top five simple-but-significant lifestyle-medicine changes they recommend.

Besides giving you three different takes on how to pick your health battles, this list gives you choices you can make without being whisked off to a reality-show fat farm — or buying a second freezer for those calorie-controlled, pre-portioned frozen meals.

As a yoga teacher and a doctor I get a lot of questions about health. To be honest I think yoga has taught me way more about being healthy, while medicine mostly has my head wrapped around the finer points of disease. That said, the two complement each other amazingly well, and at the end of the day they clearly agree on the basics. Here are the 5 fundamentals of health where eastern and western medicine share common ground, or at least get out of each other’s way!

Exercise. It’s all about sweat. A lot of yoga and exercise teachers shy away from saying you have to actually sweat, but you do. You don’t change your cardiovascular state or your energetic state if your workouts don’t include sweating. You also don’t get the glorious detox that is one of the main benefits of exercise. So find a way to sweat at least 3-4 times a week. Yoga is great, running, or plopping on one of those machines at the gym. For me a good sweat happens in half an hour, I don’t need to chain myself to a stairmaster all day. But once my shirt is sticking and my nose is dripping that is the truest simplest sign that I’ve moved and moving is the one thing our bodies need the most to be healthy.
