Do you know what is cloud computing? What should be the upcoming features of your computer? Who are your service provider and what is IT? If you do not know or is a student of computer application Advance, you’re in the right place to help them understand right from its definition, essential and the cloud computing model and its key service providers and the challenges . You will not know when the new computer technology has entered your home and office and make redundant to your expensive equipment and applications. It does not depend on your hardware is newer and what is your investment in computers, you will be tempted to declare it obsolete. Do not worry; you do not need to pay for the purchase of a new computer. But you must pay a monthly charge of your service providers of new computer technology, as you pay for your phone and your Internet service provider. Being a student of Masters in Computer Application, I can help you understand your rights to understand cloud computing. Defining Cloud Computing 1. There is a pool of short, highly scalable, and management infrastructure to accommodate the demands of the end customer and billing of consumption. 2. It is a style of computing in which the evolutionary dynamics and often virtualized resources are provided as a service on the Internet. 3. It is a new approach to shared infrastructure in which large pools of systems are linked together to provide technology services to the Internet. 4. It provides the infrastructure and environment to develop / host / run services and applications on demand, with pay as-you-go pricing as a service. What is Cloud Computing? Cloud Computing is computing on the Internet. There is a computer network access to shared pool of resources configurable. 5 Essentials of cloud computing are wide network access, on request, the pooling of resources, regional independence, “Infinite” scale and measured services. Cloud Grid Computing is the place where you can not know where your computer is in the world. Former model of computer hardware is purchased as a PC software products and applications that the product purchased. Your future cloud computer is to provide services that meet most of your perception of your needs for gaming, PC, network, mobile telephony, health, IPTV, e-learning and a cloud of secure desktop that will operate from anywhere in the world. You might be tempted to enter your office Cloud because it offers unlimited scalability, access to unlimited information technology, huge cost savings and the freedom of computer rankings, reliability and absence of damage on your computer and information resources and development of computer applications, without changing your hardware. Cloud Computing is already in the early stages in some places, Google Docs, Photo Bucket, flamboyant, Picasso, and Android Mobile OS. In India, Airtal and MTNL have facilitated Virtual PC for example. Before becoming the mainstream technology in the world, Cloud Computing, Cloud the main challenges are: 1. Legal (local and international problems of various nations) must be sorted. 2. The software architecture requires updating software available in the world. 3 interoperability standards are to be determined for various computer applications currently used on the Internet. 4. Cloud Computing: demand pay-per-use for scalability are globally agreed. 5. Codes of security companies and security agencies access must be made. 6 Dynamic Network Bandwidth must be updated to cope with the enormous information worldwide. 7. The freedom of individual choice cloud, national and international level should be done.

Northrop Grumman to pay for computer outage investigation
RICHMOND (AP) — Government contractor Northrop Grumman will pay $250,000 for an independent review of the massive computer failure that cut off some state services for days last month, and the company could be pressed to pay more if the review finds its negligence led to the crash. Northrop Grumman vice president Sam Abbate told the General Assembly’s investigative arm — the Joint Legislative …

Years ago around the end of January I would develop Chinophobia (fear of snow). Maybe it was because we had 3-5 feet of snow and I was ready for spring. Over the years I have developed âtemporary phobiasâ for a number of good reasons.
A phobia is a handy way to get myself out of unpleasant situations. I developed Dentophobia (fear of the dentist) when my wisdom teeth decided to come in, but it was cured when the pain became so unbearable that I set out for the dentist office for some relief. Phobias also provide good excuses for why I do some of the silly things I seem to do, such as, when computers were first introduced to our school.
When computers were first introduced to our school I developed instant Cyberphobia (fear of computers or working on them). As the years passed I lost this phobia, but I noticed that there are many phobias associated with computers. In other words if you have any of the following phobias I would not be even near a computer.
Neophobia (fear of anything new)âcomputers change daily, oops, hourly so you need to avoid them.
Monophobia (fear of being alone)âsince working on a computer is not group work you should avoid a computer.
Ballistophobia (fear of bullets)âYou can get near a computer and even work on one, but avoid that bullet button at all costs.
Tropophobia (fear of making changes)âdonât even be in the vicinity of a computer because this is a continual procedure and if you donât change your computer system often you quickly revert to the caveman era of computer technology.
Atychiphobia (fear of failure) â better not chance using a computer because the power may fail, the lights may flicker and then your system fails and you have to start all over. Besides that, one misplaced finger can make you wonder, âWhat happened now?â
Ankylophobia (fear of joint immobility) try sitting at a computer all day and then get up, itâs close to impossible at my age so avoid the computer.
Kaniophobia (fear of anything new or novel) with a computer itâs always changing and you may not be warned about those changes, so donât chance it.
Allodoxaphobia (fear of opinions)âyou can get on the computer, but avoid chat rooms and articles, like this, at all costs. Castisophobia (fear of sitting)âself explanatory, just avoid the computer.
Tachophobia (fear of speed)âavoid computers only if they have high speed internet and it was built last year, other wise, it is okay.
Polyphobia (fear of many things)âEverything connected to the computer is numbered in the many things category. Many functions, many buttons, many sights and especially many wires.
Technophobia (fear of technology) Thatâs what computers are all about, technology, so avoid.
May you find your life free of any phobias and typing peacefully on your computer. Have a good life.

Uninformed researchers of computer (computador) history would probably note the first computer in the mid 1930`s. In reality, this history dates nearly 2000 years ago with the invention of the abacus where the user programmed beads using formulated constructs.
Although many historians caution against the use of the word computer (computador) except to define 20th century computers, a broader understanding illuminates an instrument designed by a Frenchman and which functioned as a calculator and was designed for a tax collector in the 1600`s. Improvements to this calculator continued through the 19th century.
Similar work was underway in England and with the support of the government a `mechanical` calculator was invented. It was powered by steam and supported a fixed program for its use. This calculator went through many changes until an automatic calculator was invented. Following this flurry of discovery and invention, little changed until the early 1900`s when detailed mechanical and transportation work required complex mathematical calculations (especially calculus).
Two Census Bureau workers began to look for a means of accurately calculating information. They conceived the idea of a punch card which would be inserted into the computer (computador), read, and stored. The greatest advantage of these still slow moving machines was the ability to store large amounts of information with ease and accuracy.
The early 1940`s and the imminent World War, brought the military into the computer era (computador). New weapons requiring computer technology for effectiveness, were needed, designed and produced. These were large floor model machines and utilized the floor space of an average one family home (about 2,000 square feet). One independent computer (computador) was not adequate and a means was found to link computers which produced a more accurate and clear channel of information. These devices were not only cumbersome but they required rewiring and rechanneling for each program. Greater inventions were in progress. These new computers (computador) would be equipped with memory capacity and worker faster than any in existence at the time.
In 1947, the first modern programmable computers (computador) were designed. They contained RAM (Random Access Memory) and made it possible to access information in seconds. This technology continued to be tested and improved into the 1950`s when magnetic core memory and a transistor circuit element were discovered. These increased the memory capacity and functionality of the computers (computador). On the down side the cost to operate these machines was astronomical. By nearly sheer determination alone, these devices evolved into amazing machines able to work with a number of programs simultaneously while giving the impression that only one program was in use.
As recently as the 1960`s computers (computador) were more available and the price had become nearly reasonable for businesses. Their use however, was confined mostly to mathematically based operations such as billing, accounting, and payroll. One of the major purchasers of these devices was hospitals which stored date from patients, inventory, billing, treatments, and the like.
By the 1980`s smaller individual computers (computador) were being produced. Technology continued to astound the general public as the microchip came into existence permitting personal computers to be sold with accompanying program disks for downloading. A glance around most medium to large companies would reveal many desk top computers in use.
It would be impossible to track the history of computers (computador) without acknowledging Apple Computer and IBM for their leading edge and evolving technology. Radio Shack coupled with Apple Computer (computador) produced video games for the computer (a move from the arcade).
The ability for businesses and individuals to access the worldwide web gave birth to new and innovative marketing and communication with inquirers and/or clients. Today it is inconceivable that one attempt to research something on line and not find multiple references there. The momentum has only continued to mount and new upgrades are available nearly by the day.

The computer has been one of the most amazing and fruitful discoveries man has ever made. It has revolutionized the way man does his things. The way he eats, drinks, sleeps and even thinks. And computer itself has evolved over the years. From the Eniac I to the hand-held palmtops in executives` hands today, computer has changed with the technology. And it has changed our lives too.
The latest addition to this revolution of technical upgrading of computers is the dual-core processor technology. It refers to the CPU (Central Processing Unit- the brains of the computer) that possesses two independent and complete execution cores for each of its two processors. The concerned CPU contains two combined processors along with their cache memories and their respective controllers integrated into a singular circuit (commonly known as a silicon chip).
The dual-core process computer is suited to multitasking and handling miscellaneous tasks (often unrelated to each other). Because its CPU has two completely independent execution cores and both have independent interfaces to the front bus, it has excellent capacity to execute several programs and tasks simultaneously. Similarly, dual-core process computers may have more processor cores which is actually named as a multi-core process computer. These are highly efficient machines to conduct intensive tasks of computing or program execution at the same instance of time.
The Pentium dual-core process computer is the most preferred brand of computer in the market. It has x86-architectured microprocessors integrated onto its circuit. The 32-bit Yonah processors are a base for mobile computers while the 64-bit Allendale processors are maintained for the desktop computers. Both have absolutely different architecture as far as microprocessor technical build is concerned.
By early 2007, Intel decided to launch dual-core process computers in the field of notebooks or laptops too. This was a very important and vital decision as there were no other rivals in this phase if the market of computer architecture. Intel had only decided to launch the dual-core process computer system applying to notebooks on the behest of notebook or laptop manufacturers. The first processors to appear in notebooks using the dual-core process computer technology were the Pentium T2060, T2080 and a 32-bit Pentium M based on the Yonah core with a 1 MB L2 cache, instead of the usual 2MB cache memory.
Intel had forced a return of the Pentium brand to the market arena on 2006 with a host of low-cost single core Conroe-L core architecture processors with a 1 MB cache. These were numbered `1` to distinguish them from dual core process computer cores that had been labeled with the digit `2`.
More recently, on June 3, 2007, Intel released desktop dual-core processors from the Pentium brand. They were named as E2140 and E2160. September 2007 saw the late release of a better and updated model named E2180. These processors support the Intel64 extensions, because of their Allendale derived Core architecture. The power of these dual-core process computers was very imminent as most companies` demands exceeded supply over these multi-processor machines.
Dual-core process computer systems have taken over the world of computing today. As of its multi-tasking ability, it has gained world-wide acclaim due to its efficient, quick and yet superior quality program execution and task completion abilities. Heavier programs and complex games may be run with these dual-core process computer systems at the regular pace of conventional single-core processor systems did with light programs on the execution chart.
The age of computers had begun a long time back. But the age of sleek and efficient computing with the help of razor-edge technology has just begun with the dual-core process computer systems.

The rapid evolution of information technology is a double-edged sword. While constant improvements allow us to keep doing more in less time, the downside is that electronic equipment quickly becomes obsolete and needs to be replaced by newer, faster models. One obvious drawback of improving technology is the cost of replacing older models, but what happens to the old equipment? Many computer components are highly toxic to the environment, and virtually all electronic equipment utilizes some form of computer technology. What do we do with the computer we’re replacing? The group Local Self-Reliance estimates that about 75% of obsolete computers and other IT equipment is being stored, creating a time bomb waiting to go off. It will be a dark day for the environment when we all finally decide to dispose of this clutter.
Mercury, chromium, and lead are a few of the hazardous materials found in batteries, cathode ray tubes, and circuit boards. These toxins will be released into the environment if all this outdated equipment disposed of in traditional ways. Soil and water will be affected if this material is dumped in a landfill, and incineration releases toxic ash into the air.
This is why we shouldn’t simply trash our obsolete computers. Many organizations are dedicated to recycling old computer hardware. Recycling helps the environment and enhances quality of life for all of us. There are many volunteer and nonprofit groups that provide recycling services, recovering over 112 million pounds of valuable materials each year from old computers and other electronic equipment. Glass, plastic, steel, and precious metals can all be reused. Most of us don’t realize that even keyboards, CDs, floppy disks, ink cartridges, and power cords contain easily reusable materials. Some peripheral hardware can be utilized with a new computer, such as speakers and reusable disks.
Staples is one company that has instituted a green policy, where old equipment can be dropped off seven days a week for a $10 handling fee. Company spokesperson Mark Buckley estimates that in this country alone, 13,000 computers are disposed of daily.
According to Mark Buckley, of Staples, which has a green policy on accepting old equipment 7 days a week in a drop-off scheme, for a handling fee of 10$, estimates that 13,000 computers are disposed of every day in the U.S. While the company keeps many of the component parts, Staples hands off CR tubes and other hazardous materials to Amandi Services, which makes television components utilizing their own recycling technique. Another organization utilizing new technologies to complement and enhance the usual pulverizing and shredding is Creative Recycling. Their reclamation utilizes very efficient dust filters and negative air pressure in a controlled atmosphere. The output of this system includes various metals, plastic, and glass. The company aims to provide cost-effective solutions for government organizations and has invested millions of dollars in equipment in an attempt to lead the development of new recycling technology.
Not many people have noticed that recycling legislation has been passing in Europe for the last five years. That was when the Waste Electrical and Electronic Equipment Directive was drafted, forcing computer manufacturing companies to pay for the recycling of old equipment in a safe manner. Unfortunately, since the industry operates with very small profit margins, most people believe the costs will be passed on to consumers in the form of higher computer prices. The additional cost per computer could be as much as $50, according to industry analyst Gartner. And while most people wouldn’t balk at paying a small premium to have their old equipment disposed of properly, the European Union is requiring more stringent demands of green components in the future. This will also increase manufacturing costs in the short term, raising prices even higher.
There aren’t many companies currently recycling computers in England, but the computer companies themselves are beginning to step up and provide alternatives for recycling old equipment. Dell is one computer manufacturer pioneering new ways to recycle old computer equipment. Find out more about computer disposal and recycling by visiting their website at http://www.computer-recycling-center.com.
Compared to Europe, this country is fortunate to have many local outlets for computer recycling. But don’t wait too long to drop off your old computer at a local recycler, because the cost is only going to get higher.
