Online Education – Do You Want To Return To School?

In our rapidly changing global world, millions of students are currently taking college-level online (distance education) classes. Private and public universities in the United States and abroad are offering Certificate, Baccalaureate, Masters and Doctoral degree programs over the Internet to adult learners. From Ivy League to Community Colleges, an increasing number of students can log on to their classes from home, work or while commuting by bus and train. Adult learners frequently juggle a myriad of responsibilities including raising children, career, and care giving for senior parents. Formerly, a university of interest may have been out of reach geographically. Presently, an employee located in the United States can register for classes taught half way around the world. Non-traditional venues outside of the more traditional classroom offer viable opportunities for continuing one’s education.

Adult learners make up the largest demographic of post-secondary institutions in the United States. For this student group, the benefits of online academic programs are:

o To update current skill sets

o To learn new skill sets

o To earn an undergraduate or graduate level degree

o The fulfillment of academic requirements necessary for a current job or promotion

o To change careers

o The satisfaction of certification or licensure requirements

o Personal and spiritual growth and development

Not for the faint of heart, success in distance education academic programs requires high levels of stamina, discipline, and motivation. A good candidate must be computer literate, possess the ability to read massive amounts of material in short-time frames, have good writing and communication skills, hold high expectations for good grades, enjoy applying critical thinking and commit a minimum of 15 hours per week per course (be prepared to allocate more, if necessary).

The Internet and the World Wide Web provide the critical technology platform for distance education. University technological and operational infrastructures (including hardware, software and transmission) provide the additional cornerstones to the technology platform needed to execute distance education programs. The delivery of academic content may be accomplished in several formats. The more traditional venues are correspondence courses, videos, audio-cassettes, CD-ROMS, and broadcasts via television and radio. Modern formats include synchronous and/or asynchronous education content distribution channels. Synchronous delivery refers to real-time interaction between instructor and student i.e., two-way video-conferences, whiteboards, chat rooms, telephone software (ex. Skype), and mobile technology devices. Asynchronous interaction does not involve real time communication. Instead, interaction between instructor and student is accomplished through the use of e-mail, DVDs, and the traditional education delivery formats.

As a student, you will need a desktop or laptop computer, an Internet Service provider, a cell phone, software (i.e., word processor, financial spreadsheet, calendar and Power Point), a backup storage disk drive (nothing can make your heart drop faster than losing a body of work that you’ve diligently developed), a headset with microphone for virtual team discussions and the traditional school supplies. Optional technology may include memory upgrades, scanners, digital scanners, and fax machines.

Ten Tips For The Successful Online Student:

o Have a credit card or debit card ready for downloading e-books and other required course reading materials.

o Maintain a list of more than one bookstore in the event that a required textbook is sold out. It’s always a good idea to obtain a list of the required textbooks midway through the term and order in advance for the following term.

o Do not be shy about asking for help if needed. I cannot stress enough the importance of communicating openly with your professor or instructor about course material that you may not understand. Online academic programs tend to move rapidly and course content that you do not understand will most likely cause problems down the road resulting in frustration and possibly, lower grades.

o Seek out a tutor. If there are areas that you know need strengthening, even before the class begins, have a tutor on stand-by. Also, the telephone number of a computer specialist should be in your rolodex.

o Time management will be critical. Keep a planner. Read your syllabus as soon as it becomes available and plan accordingly.

o Uphold your responsibilities as a virtual team member. Your contributions will directly impact the team grade.

o Exercise. Long hours at the computer can cause strain on the neck, shoulder, arm and back muscles, not to mention the hands. Remember to periodically stretch and tone.

o Eat a healthy diet. Keep good healthy recipes handy. Hydrate. Avoid heavy snacking on calorie-laden food and instead eat lots of fruit and vegetables. Avoid white flour and choose high fiber grains.

o See your doctor. A healthy body feeds a healthy mind.

o Stay in contact with your Academic Advisor to be sure that you are satisfying the requirements needed to complete your degree.

In the Fall term of 2006, 3.5 million students representing 20% of all U.S. higher education students, took at least one online course (2007. The Sloan Consortium). It is projected that distance education will continue to grow in popularity domestically and internationally. The most commonly offered online academic programs are Business, Computer Science and Engineering, Education, Engineering, Library Science, Nursing, and Public Health. Whether you select a community college, public institution, private institution or Ivy League university, enjoy the learning experience.

“But” vs “And”

Two three–letter words: “but” and “and.” In grammatical terms, they are called conjunctions. They bridge two clauses of a single sentence together. In communication (and negotiation), these words are subtle manipulators of exclusion or inclusion. Generally speaking, “but” excludes, denies, discounts or in some way rejects the previous clause. For example, the statement “she is a very productive employee but she can be a bit demanding” is subtly different than “she is a very productive employee and she can be a bit demanding.” In the first example, the “but” tends to convey a negation of the first clause of the sentence in favor of the second clause of the sentence. In the next example, the “and” tends to convey an inclusion of the first clause along with the second clause.

Take another example: “Yes I understand you need to meet with me before tomorrow’s meeting but my schedule is packed full” vs. “I Yes I understand you need to meet with me before tomorrow’s meeting and my schedule is packed full.” In this example, by using “and” instead of “but” the speaker not only avoids negating the initial clause but also conveys to the listener that his/her concerns about needing to meet are acknowledged.

Using “and” is also a much softer way to say no. For example, the typical “yes, but” can easily be replaced with “yes, and.” For example, the request “We need to purchase new computers” can be responded to with “yes I know, but we can’t until next year” or “yes I know, and we can’t until next year.” The “and” does not negate the “yes” whereas the “but” does tend to convey a sense of canceling out that which preceded the “but.”

The use of “but” is extraordinarily common. In fact, few people actually recognize the subtle influence of using but. If you were to consciously attempt to change “but” to “and” in your speaking, you will notice how odd it feels. But, it is a worthwhile exercise if for no other reason than to become more comfortable with the ability to switch from one to the other. However, there can be a more important reason: using “and” instead of “but” can positively influence dialogue. When using “and” instead of “but” there is a sense of inclusion and acceptance even if the conclusion is a denial or refusal.

Try it out over the next several days. Listen to others’ sentences and when you hear “but” change it in your own mind to “and.” Then, start listening to your own sentences. When you hear yourself about to say “but” change it to “and” but remember one thing…oops…and remember one thing…

An Aion Primer – Basic Aion Guide

The massively multiplayer online RPG known as Aion (full name: “Aion: Tower Of Eternity”) is NCSoft’s latest foray into the MMORPG genre. So, what’s Aion all about and what makes it different from the myriad of other popular MMO games on the market now? This article aims to be your guide to the world of Aion, to give you a primer on the basics of how Aion works and what you can expect from the game.

The game takes place in two separate “worlds”, Elysea and Asmodae, inhabited by the Elyos and Asmodians, respectively. Elysea is bright and cheerful, whereas Asmodae is more dark and sinister. Players begin the game as humans in whichever world they choose. Players gain experience by completing quests and defeating enemies, which they then use to “level up” their characters. Once characters reach the required level, they become winged immortals known as “Daevas”. Once a character has become a Daeva, they travel to the capital city of whichever world they inhabit, to begin their new lives. Features

Character Creation & Customization

An important feature in any RPG, Aion features a robust character creation and customization system. This system allows players to fine-tune the height, weight and scale of various body parts. A variety of hair styles, skin colors, facial textures and voices are available to choose from. Players can go really in-depth with their character’s detailing, by adjusting eye shape/color, nose shape, ear size/shape, and tattoos for the character’s face and/or body. Aion also features the ability to dye a character’s equipment to change its color, and the ability to interchange graphics between weapons and armor that the characters have in their inventory (though this graphic swapping must be done between items of the same type).

Skill Chains

Many RPGs allow characters to gain and improve new skills as they progress. Aion introduces a subtle twist to this game mechanic with “Skill Chains”. With “Skill Chains”, skill upgrades may only be performed in a certain order (hence the term “chain”).

Classes

There are four “primary” classes: Warrior, Mage, Scout, or Priest. Once characters reach level 9, the player can then choose from two “specialized” classes related to their original “primary” class. Warriors can become either a “Templar” or “Gladiator”. Likewise, Mages can become either a “Sorcerer” or “Spirit Master”, Scouts can be either “Assassin” or “Ranger”, and Priests can become either a “Cleric” or a “Chanter”. Professions

On top of your character classes, there are six “crafting” professions (Alchemy, Cooking, Tailoring, Handicrafting, Weaponsmithing, and Armorsmithing) and two “extracting” professions. The extracting professions are learned automatically by each player, but the crafting professions must be learned manually. A single character is able to learn ALL of the crafting professions, but only master two. Becoming a “master” of a profession gives the player a fancy title and a boost to his or her stats.

Grouping

Players can join together to form a “group”. Groups can accommodate up to six players. Certain parts of Aion are designed for group play, and in some areas a group is required for entrance. Building on the group mechanic, in Aion up to four groups may form what is known as an “alliance” when greater numbers are needed. However, being a part of an alliance can limit your rewards from smaller quests intended for single or group play.

PvPvE system

The “Abyss” is a PvP area physically located between the two game worlds. Once characters reach higher levels, much of the game of Aion revolves around PvP encounters in this area. The Abyss features strongholds which can be controlled by “Legions” (Aion for “guild”). Players battle it out to gain and keep control of these various strongholds. Again, Aion introduces another twist with siege weapons players can obtain from raids, and use in these battles. Control of a stronghold means income from taxes, and players get perks from stores and NPCs. Battling it out with your fellow players in the Abyss will get you “Abyss Points”. These points are used to rank you among the rest of the Aion players out there. Why does this matter? Well, higher ranks unlock visual upgrades to your characters wings, and you can use your Abyss points to purchase high-end armor and weapons.

How to Cure Ringworm?

Ringworm is a very contagious skin fungal infection. It can affect all individuals and even animals. During the infection stage of the ringworm, they produce fungal spores that can be transmitted to others. When you become exposed to fungal spores, you are at high risk to develop ringworm. But ringworms are treatable, and ringworm cures are very helpful to remove and kill fungal spores.

It is very essential to kill the fungi, and prevent the spread of ringworms to your body and to other people or animals. Here are some tips that will help you:

– Perform environmental disinfection regularly. It is important to maintain a clean environment because fungal spores can be present anywhere, especially to places where the infected person has been exposed to. Bleach is common in every household, and is very effective in disinfecting the environment. You just need to make a 1:10 bleach and water solution, and use it in decontamination of floors and surfaces. This will effectively kill the fungal spores, and prevent its transmission.

– Use a vacuum with HEPA filters. High Efficiency Particulate Absorbing or Arrestance (HEPA) filter removes at least 99.97% of airborne particles such as dust and fungi. It is very useful in cleaning carpets and upholstered furniture to remove fungal spores.

– Isolate infected pets. It is very important to separate your infected pet from other animals. You should not touch or come in contact with the infected pet because you can contract the fungal spores that cause ringworm. Consult your pet’s veterinarian so that you can determine what type of treatment will help your pet resolve its ringworm.

– Do not share personal articles. Sharing is a good act but if you have ringworms, it is a big no to share your personal items to others. Your things are contaminated with fungal spores. You should keep them and disinfect them using bleach.

– Keep a clean body. Fungi flourish in dirty areas. Proper personal hygiene should be observed to prevent the spread of ringworm on your skin. It is also important to perform regular hand washing after treating your ringworm, and after touching or treating your infected pet because you can obtain fungi spores from it.

– Maintain a sweat-free body and wear comfortable clothing. Fungi thrive in hot and moist areas of your body such as armpits, groins, and areas which have folds especially to obese individuals. You should keep yourself dry and avoid wearing tight clothes.

– Use a natural ringworm remedy. Natural ringworm remedies are found to be effective against ringworm, and they are absolutely safe to use. They are medicinal herbs that use leaves or extracted oil to cure ringworm such as turmeric (Curcuma longa), coconut oil (Cocos nucifera), mustard seeds (Brassica nigra),cassia leaves (Cassia fistula), holy basil leaves (Ocimum sanctum), butea seeds (Butea monosperma), and papaya seeds (Carica papaya). They are applied directly over the ringworm patch. Carrot (Daucus carota) and spinach juice (Spinacea oleracea) are also helpful in treating ringworm because they contain large amount of beta-carotene, which are very good for skin care.

– Apply topical creams. Topical creams are effective for ringworms that have mild symptoms. They are over-the-counter medications that help to relieve ringworm symptoms and kill fungi that cause ringworms. Topical treatment should be used for 2 to 4 weeks to effectively eradicate the fungi. Topical medications include Miconazole (Micatin, Desenex, Daktarin, Monistat-Derm, and Decocort), Clotrimazole (Mycelex and Lotrimin), and Terbinafine (Lamisil AT, Lamisil, and Lamisil Dermgel).

– Administer anti-fungal pills. Anti-fungal pills are systemic treatment for severe cases of ringworm. It is recommended to consult your physician so that you will be advised on the proper dosage and length of treatment using oral anti-fungal medications. Anti-fungal pills include Griseofulvin (Gris-PEG, Grifulvin V, Fulvicin P/G, and Griseofulicin), Itraconazole (Sporanox and Sporanox PulsePak), Terbinafine (Lamisil), and Fluconazole (Diflucan).

Mononucleosis Explained

Mononucleosis is a viral illness that is common among young adults but can affect people of almost any age. Severe sore throat, swollen lymph nodes, fever and extreme fatigue are the recognizable hallmarks of this condition. Why the disease is more common in teens remains unclear. It may have something to do with the lifestyle, poor diet, not enough rest and stress, all of which lowers the resistance of the immune system. The underlying culprit is the Epstein-Barr virus (EBV). This virus, a member of the herpes virus family, is so common that 95% of all adults test positive for exposure to it. The EBV has been implicated as playing a role in some uncommon malignancies later in life or another condition chronic fatigue syndrome. However, keep in mind that the virus is very common. Even though exposed some time in their life by adulthood, most people do not manifest any clinical symptoms of mononucleosis. Viral transmission occurs through intimate contact with saliva or blood of the infected person. Hence, the antiquated name of the “kissing disease”. The virus is not airborne. The risk to others in the family or friends is very low unless there is intimate contact.

Severe sore throat, extreme fatigue, swollen glands and lymph nodes characterize the typical symptoms. The inflammatory process usually affects the liver and spleen resulting in some enlargement. In a small number of severe cases, abdominal pain or difficulty swallowing may be an issue. Twenty percent of people with mono develop a fine red rash resembling measles. Some medications in particular amoxicillin based antibiotics can also trigger the rash. The incubation period from time of exposure to onset ranges from 14 to 45 days. The average illness lasts 4 weeks. The first two weeks are most difficult because of the intensity of the symptoms including a severe sore throat that makes it awkward to maintain an adequate diet. The fatigue makes people want to sleep a lot. People usually miss two weeks of school or work during this time. The second two weeks are usually quite a bit better but energy levels are still waning. Getting up in the morning feeling good and somewhat energetic, but running out of gas after a few hours is characteristic. Some modification of activities with a limited schedule during the second two weeks is to be expected. A specific blood test can confirm the diagnosis in the doctor’s office. An exam to rule out other similar conditions is prudent.

Since it is a viral illness it will run its own course, there is no specific treatment. The majority of cases improve with rest and a balanced diet. In the rare severe case, other medications such as a steroid or an anti-viral drug may be used. There are a few instances when a second bacterial infection such as strep throat may occur at the same time. Appropriate tests can easily determine whether an antibiotic is necessary to treat a secondary infection. Symptomatic treatment is helpful just like treating the flu. Ibuprofen or acetaminophen for fever or muscle aches, plenty of clear liquids and trying to maintain a healthy balanced diet are nonetheless important. Avoiding alcohol for six weeks is suggested while the liver inflammation subsides spontaneously. The biggest frustration for people is simply the lack of energy and fatigue. It can usually take 4 to 6 weeks or more before normal stamina returns.

How To Get Rid Of Cold Sores Fast And Resume Your Daily Life

Suddenly you feel the tingling sensation at the edge of your lip. There is no doubt in your mind that a cold sore is coming. Although you can’t cure it at the moment or prevent it completely, but you can speed up the healing with the following remedies.

Peppermint Oil

Essential oils can help your cold sores to heal faster. One study shows that peppermint oil can eliminate herpes simplex virus outside the cells in 3 hours. In other words, essential oils are not effective if the virus is hiding in the nerve. To use peppermint oil, you need to dilute it with olive oil because at high concentration, it is toxic. Apply it when you notice the tingling sensation.

Lysine

Taking high dosages of lysine has been found to speed up healing of cold sores. It replaces arginine in the cells. Arginine is the fuel for herpes simplex virus. The lack of arginine in the cells forces the virus to retreat.

You can reduce the consumption of foods that contain arginine. These include grains, chocolate, nuts, and seeds.

If you don’t want to take lysine supplements, increase the intake of lysine rich foods such as meat and dairy products. Just make sure they provide between 3000 and 9000 milligrams of lysine daily.

Abreva

Abreva is FDA-approved over-the-counter cream. It contains docosanol or behenyl alcohol that can get rid of cold sores fast. For best results, you have to use it as soon as the first symptom appear. It requires up to 5 applications per day.

Compeed

One study compares the speed of healing between Compeed Cold Sore Patches and acyclovir 5% cream. The result is that Compeed has the similar quick healing abilities as acyclovir cream. According to consumers’ reviews, many find that their cold sores clear quickly after patching their sores with Compeed. Unlike topical creams, Compeed is not messy. It is transparent so you don’t even know the patch is there. It also prevents the virus from spreading. In addition, it is an ideal remedy for pregnant women who have concerns about prescriptions.

Manage Your Stress

When you are under stress, your immune system weakens. This does not help your body to recover quickly for the herpes outbreak. If you want the cold sores to go away faster, you have to reduce your stress. Take a stroll, or join yoga classes. Modify your hectic schedule to give you time to relax.

The problem I find with today’s cold sore remedies is the timing. Most treatments will work the best if you act the moment you spot the tingling sensation. If you fail to do so, it will take longer time for you to resume your daily activities. Although the above remedies can get rid of cold sores quickly but what if you have to attend a major meeting or event tomorrow?

Building a Career Through Online Education Courses

Education is a systematic process of acquiring knowledge and skill necessary for personal growth and development. The practical application of education in a specific field of study can jumpstart a professional career or establish a foundation for possible business ventures. Making an investment in education can be one of your most significant and wisest decisions in life because of its immediate impact to your future. Distance education plays a vital role in connecting educators and learners worldwide, breaking the barriers imposed by time constraints, distance, disabilities and socio-economic status. Distance education courses are being offered by Open Institutions to answer the call for internationally recognised quality education and training. Whether you are a student who just started on the path of learning, a professional in your field of study and want to further your education through advanced and specialized programs, or a person who is restricted by travel or health concerns, online courses definitely have the answers for you.

Many individuals are asking on how effective distance education when delivering the methodologies of teaching. Online education classes are as effective as traditional face-to-face instruction done in colleges and universities. The keys to establishing a successful online study depend on the dedication and focus of the learner, and timely peer-support by the open institution. The people behind the curriculum and online support offered through distance education are professionals and experts in their field, so you can be sure of having the quality education and training that you are looking for. Online instruction is divided into four major classifications, namely: voice, video, data and print. Voice or use of audio as medium of communication includes the telephone, tapes, radio and audio-conferencing.

On the other hand, videos may come in the form of instructional tapes or CDs, or combined with voice and data as file attachments. Print media can be in the form of instructional books, guides, course outlines or assessments which are delivered through courier or mailing system. Data is the widely used form of instruction due to the advances in technology in computers and the internet. Information is transmitted electronically and may be in the form of Computer Assisted Instruction (CAI), Computer Managed Instruction (CMI), Computer Mediated Education (CME), or a combination of any of these. The delivery of education and training became better, faster and economical since all the instructional materials and methods of teaching are coursed through e-mail (electronic email) or e-fax (electronic facsimile), online conferencing and other World-Wide Web applications. This would include advances in communication by utilizing Voice over Internet Protocol (VoIP). By making use of all the available communication media, online learning study is delivered fast and efficient.

Distance learning has many advantages that individuals on different levels of learning can take advantage. It provides the flexibility of choice when you want to finish a course or where you want the training to take place. Assessments and projects are given at the end of a specified topic, submitted to education professionals and experts of their field for evaluation, and then feedback is given to determine if a learner is to advance to the next level or if further reading is required prior to advancement. You can never be too old or too young in order to start a life changing career, or build the basic foundation to start a new business. All you would need is the proper self-motivation and focus so you can look forward and fulfill your dreams in life.

What Is an Investment?

One of the reasons many people fail, even very woefully, in the game of investing is that they play it without understanding the rules that regulate it. It is an obvious truth that you cannot win a game if you violate its rules. However, you must know the rules before you will be able to avoid violating them. Another reason people fail in investing is that they play the game without understanding what it is all about. This is why it is important to unmask the meaning of the term, ‘investment’. What is an investment? An investment is an income-generating valuable. It is very important that you take note of every word in the definition because they are important in understanding the real meaning of investment.

From the definition above, there are two key features of an investment. Every possession, belonging or property (of yours) must satisfy both conditions before it can qualify to become (or be called) an investment. Otherwise, it will be something other than an investment. The first feature of an investment is that it is a valuable – something that is very useful or important. Hence, any possession, belonging or property (of yours) that has no value is not, and cannot be, an investment. By the standard of this definition, a worthless, useless or insignificant possession, belonging or property is not an investment. Every investment has value that can be quantified monetarily. In other words, every investment has a monetary worth.

The second feature of an investment is that, in addition to being a valuable, it must be income-generating. This means that it must be able to make money for the owner, or at least, help the owner in the money-making process. Every investment has wealth-creating capacity, obligation, responsibility and function. This is an inalienable feature of an investment. Any possession, belonging or property that cannot generate income for the owner, or at least help the owner in generating income, is not, and cannot be, an investment, irrespective of how valuable or precious it may be. In addition, any belonging that cannot play any of these financial roles is not an investment, irrespective of how expensive or costly it may be.

There is another feature of an investment that is very closely related to the second feature described above which you should be very mindful of. This will also help you realise if a valuable is an investment or not. An investment that does not generate money in the strict sense, or help in generating income, saves money. Such an investment saves the owner from some expenses he would have been making in its absence, though it may lack the capacity to attract some money to the pocket of the investor. By so doing, the investment generates money for the owner, though not in the strict sense. In other words, the investment still performs a wealth-creating function for the owner/investor.

As a rule, every valuable, in addition to being something that is very useful and important, must have the capacity to generate income for the owner, or save money for him, before it can qualify to be called an investment. It is very important to emphasize the second feature of an investment (i.e. an investment as being income-generating). The reason for this claim is that most people consider only the first feature in their judgments on what constitutes an investment. They understand an investment simply as a valuable, even if the valuable is income-devouring. Such a misconception usually has serious long-term financial consequences. Such people often make costly financial mistakes that cost them fortunes in life.

Perhaps, one of the causes of this misconception is that it is acceptable in the academic world. In financial studies in conventional educational institutions and academic publications, investments – otherwise called assets – refer to valuables or properties. This is why business organisations regard all their valuables and properties as their assets, even if they do not generate any income for them. This notion of investment is unacceptable among financially literate people because it is not only incorrect, but also misleading and deceptive. This is why some organisations ignorantly consider their liabilities as their assets. This is also why some people also consider their liabilities as their assets/investments.

It is a pity that many people, especially financially ignorant people, consider valuables that consume their incomes, but do not generate any income for them, as investments. Such people record their income-consuming valuables on the list of their investments. People who do so are financial illiterates. This is why they have no future in their finances. What financially literate people describe as income-consuming valuables are considered as investments by financial illiterates. This shows a difference in perception, reasoning and mindset between financially literate people and financially illiterate and ignorant people. This is why financially literate people have future in their finances while financial illiterates do not.

From the definition above, the first thing you should consider in investing is, “How valuable is what you want to acquire with your money as an investment?” The higher the value, all things being equal, the better the investment (though the higher the cost of the acquisition will likely be). The second factor is, “How much can it generate for you?” If it is a valuable but non income-generating, then it is not (and cannot be) an investment, needless to say that it cannot be income-generating if it is not a valuable. Hence, if you cannot answer both questions in the affirmative, then what you are doing cannot be investing and what you are acquiring cannot be an investment. At best, you may be acquiring a liability.

IPv4 Vs IPv6 (Advantages and Disadvantages)

We can see the rapid growth of internet users in last few years and this increase also create challenges for internet management groups, stake holders and service providers. Day by day infrastructure of internet is expanding and we can even enjoy the service of internet in villages and remote areas. Increased of usage also increase online devices. In start internet protocol addressing (a specific IP addressing for each online entity) was designed on 32 bit and this scheme IP version called IPv4.IPv4 addressing is like 203.128.076.001. decimal is used to make the IPv4 addresses more palatable for humans and a 32-bit address becomes 4 decimal numbers separated by the period (.) character. If we calculate these decimal values and we can get the total number of devices can be participate on this protocol (256x256x256x256) = allows for 4,294,967,296 addresses. It is about 4 billion of addresses and in early days of internet no one can think, 4 billion slot will be full. here we shall discus some disadvantages of IPv4 as we have seen addressing capability problem and after that we shall go through the solution which will replace IPv4 and addressing structure of the new addressing scheme. we shall go through some disadvantages of IPv4 and new features of IPv6.

Rapid Growth of the Internet and the Exhaustion of the IPv4 Addressing

IPv4 allows for 4,294,967,296 addresses which is about 4 billion and IP allocation limits the public IP addresses to a few hundred million. Cause of this limitation companies using NAT (Network Address Translator) to map single public IP to multiple private IP addresses.

IPv4 Security at IP Level

When we communicate at public medium we need to encrypt data to maintain security and privacy. After a passage of time we have now security for IPv4 packets. This security knows as internet protocol security or IPSec but this is an optional for IPv4.

Internet Backbone Maintaining Large Routing Tables

In IPv4 network IDs allocation is very critical and currently more than 87000 routes in the routing tables of internet backbone routers today. The routing infrastructure is based on flat and hierarchical routing.

Quality of Service Concern in IPv4

Now a days internet users are not only limited with browsing and searching data. Current users are well aware of text and voice and video chat and video conferences and online video libraries. This kind of communication need real time data transfer for quality of service. Normally for these kind of services we use UDP (User Data-gram Protocol) or TCP (Transmission Control Protocol).IPv4 TOS field has limited functionality and, over time, has been redefined and locally interpreted. Additionally, payload identification that uses a TCP or UDP port is not possible when the IPv4 packet payload is encrypted.

IPv6

As we can see we have some basic problems in practice of IPv4 now we will check some new features of IPv6. here I like to describe the some of basic features of IPv6. Deployment of IPv6 is a big challenge for internet management groups, stake holders and service providers. It is difficult but not impossible. We can see benefits of IPv6 here. Biggest upgrade jump from IPv4 32 bit to IPv6 128 bit.

IPv6 Header Format

New header is designed to minimize header overhead. by moving both nonessential and optional fields to extension headers that are placed after the IPv6 header. IPv6 header is more efficiently processed at intermediate routers and that generates efficiency. IPv6 is 4 time larger than IPv4 and its header size is twice than older version.

IPv6 Large Addressing Space

In IPv6 source and destination addresses is based on 128 bit. 128 bit addressing can produce over 3.4 x 1038 possible combinations. Currently we can say this is enough but who know about future may be it also face same problem like IPv4 after some decades. 128 bit addressing allow us multiple levels of sub-netting and address allocation. So we can say that we have plenty of address for use in future.

Addressing and Routing Infrastructure Efficiency in IPv6

IPv6 designed to create an efficient, hierarchical, and summarize able routing infrastructure that is based on the common occurrence of multiple levels of Internet Service Providers. It reduce the size of routing table of backbone routers. Which is can cause of efficient internet experience.

Security features is now built-in

IPv6 has been design to support IPsec (AH and ESP header support required) also support mobility version Mobile IPv6. IPSec based on two types of extension headers and a protocol to negotiate security settings. The Authentication header (AH) provides data integrity, data authentication, and replay protection for the entire IPv6 packet. It is better form developers who built-in security features in development of IPv6 rather we bolt on later.

Quality of Service (QoS) of IPv6

As we have already seen about the UDP and TCP protocols for streaming and other multimedia services on internet. Cause the usage of these services are increasing day by day IPv6 have a flow level field in its header which make better and special handling for packets from source to destination.

2. The nurses, some workers would act as nurses to the eggs laid by the Queen bee. What they do is visit the cell where the eggs are laid. The nursing bees are the young bees for they cannot do other functions yet.

3. Food gatherers are the ones in-charge of looking for food. Bees pass the food from one worker to another to make work more precise. As the bees age, their ability to help in the transmission of food becomes better as well.

4. Guards and robbers are also the functions of bee workers. The guard bees would ensure the safety of the honeybee. They are usually stationed in the entrance of the beehive.
