Cloud computing is all the rage. "It's become the phrase du jour," says Gartner senior analyst Ben Pring, echoing many of his peers. The problem is that (as with Web 2.0) everyone seems to have a different definition.
As a metaphor for the Internet, "the cloud" is a familiar cliché, but when combined with "computing," the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud," including conventional outsourcing.
Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.
Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging.
InfoWorld talked to dozens of vendors, analysts, and IT customers to tease out the various components of cloud computing. Based on those discussions, here's a rough breakdown of what cloud computing is all about:
1. SaaSThis type of cloud computing delivers a single application through the browser to thousands of customers using a multitenant architecture. On the customer side, it means no upfront investment in servers or software licensing; on the provider side, with just one app to maintain, costs are low compared to conventional hosting. Salesforce.com is by far the best-known example among enterprise applications, but SaaS is also common for HR apps and has even worked its way up the food chain to ERP, with players such as Workday. And who could have predicted the sudden rise of SaaS "desktop" applications, such as Google Apps and Zoho Office?
2. Utility computingThe idea is not new, but this form of cloud computing is getting new life from Amazon.com, Sun, IBM, and others who now offer storage and virtual servers that IT can access on demand. Early enterprise adopters mainly use utility computing for supplemental, non-mission-critical needs, but one day, they may replace parts of the datacenter. Other providers offer solutions that help IT create virtual datacenters from commodity servers, such as 3Tera's AppLogic and Cohesive Flexible Technologies' Elastic Server on Demand. Liquid Computing's LiquidQ offers similar capabilities, enabling IT to stitch together memory, I/O, storage, and computational capacity as a virtualized resource pool available over the network.
3. Web services in the cloudClosely related to SaaS, Web service providers offer APIs that enable developers to exploit functionality over the Internet, rather than delivering full-blown applications. They range from providers offering discrete business services -- such as Strike Iron and Xignite -- to the full range of APIs offered by Google Maps, ADP payroll processing, the U.S. Postal Service, Bloomberg, and even conventional credit card processing services.
4. Platform as a serviceAnother SaaS variation, this form of cloud computing delivers development environments as a service. You build your own applications that run on the provider's infrastructure and are delivered to your users via the Internet from the provider's servers. Like Legos, these services are constrained by the vendor's design and capabilities, so you don't get complete freedom, but you do get predictability and pre-integration. Prime examples include Salesforce.com's Force.com, Coghead and the new Google App Engine. For extremely lightweight development, cloud-based mashup platforms abound, such as Yahoo Pipes or Dapper.net.
5. MSP (managed service providers)One of the oldest forms of cloud computing, a managed service is basically an application exposed to IT rather than to end-users, such as a virus scanning service for e-mail or an application monitoring service (which Mercury, among others, provides). Managed security services delivered by SecureWorks, IBM, and Verizon fall into this category, as do such cloud-based anti-spam services as Postini, recently acquired by Google. Other offerings include desktop management services, such as those offered by CenterBeam or Everdream.
6. Service commerce platformsA hybrid of SaaS and MSP, this cloud computing service offers a service hub that users interact with. They're most common in trading environments, such as expense management systems that allow users to order travel or secretarial services from a common platform that then coordinates the service delivery and pricing within the specifications set by the user. Think of it as an automated service bureau. Well-known examples include Rearden Commerce and Ariba.

Tamil Nadu HSE Results
Its time for the Higher secondary students to start worry about their chances of getting their seats in top colleges. Some would like to know "How to know about the last year's way of filling seats".Here is the way you can know about the vacancy
http://www.collegesintamilnadu.com/Counseling/TNEA_Cutoff_Search.asp
But some students would think they have not got marks for what they would have, this would be really an upset for those students.They can go for revaluation where they could get marks if not what they like to have, atleast 25% of their expectation more.They also see their ranks not in a clear way, but they can have a outline of what they would get.Here you can see the cut-offs and their ranks and also the number of students who got their cut-offs.
http://www.collegesintamilnadu.com/Results/HSCAnalysis.asp
This is the future or one could say the turning point of those students or crunch time in their career.But before one choosing the college one should be in a clear mind that what he/she is going to choose and should stand with their decision if one could get what they would want to get then it will be good but it will not happen for all. So one should be wise in chosing their career.I hope that you would all get what you wish to have and i also pray to that almighty.All the Best Guys!!!!!!!!.

Adding a RAM into a desktop PC
Welcome to this new article about adding a new RAM into your PC
There are two ways of adding a RAM into your PC :
There are two ways of adding a RAM into your PC :
- You can just remove the one which is already installed and insert the new one.
- Or you can add the RAM in athe additional slot.
These are the two ways of adding a RAM.
RAM is just like a video game chip you just have to add that in the slot provided but before inserting you needn to remove the cabinet of your PC and sight the slot where to insert your RAM.Its easy just like inserting a catridge of a video game.After removing your cabinet you have to insert the RAM in the additional slot with correct pins then you have to ensure that the RAM has been properly inserted.If you have not inserted it properly then you might end up with a problem while booting your PC.But you can recognize it easily as the PC starts beeping in an irregular fashion so that you might see through it.
After inserting your RAM and booting you need to check whether the newly added RAM has been added or not .This can be ensured byt ssing this in My Computer>Properties where you can see the additional memory whhich has been added to your system. Thats it Finally you have succeded in you intermediate stage of computer handling.
People might say that it is not good to open the PC but you don't worry just go ahead .have a nice time i hope that you might enjoyed and have been successful in adding a new RAM to your PC.

College guys towards internet
High school and college students use the internet in some of the same ways as well as in some different ways. Every type of student can use the internet for communication which can result in a way of collaborating on project work, studying for tests, and trading notes. Another major use of the internet is for looking up research material. Before the invention of the internet, students had to use hardcopies of books, newspapers, journals, and encyclopedias. While using hardcopies is still encouraged by teachers and professors, most of these resources are available to students without ever having to leave your chair.
While computers and especially the internet are very useful tools, not everyone has the same opportunities to use such technology. Whether it is factors such as location and availability or factors such as income, age, and race, there is a digital divide that exists. The digital divide refers to those who have access to digital information and those who do not. The digital divide is also implied to those who do not have the sufficient knowledge to use information technologies which can result from a lack of education on how to use them.
Even if families do not have computers and internet access at home, schools are pushing students more than ever to become fluent with information technology. A quote of a high school student in The Digital Disconnect says “our teacher is telling us not to work out of books. She actually requires us to do our stuff on the Internet. There’s this one web site that we usually go to.” Most students have accepted the use of technology, but not all. There are those who struggle to learn and those who have no desire to have technological skills. Although there are people of this nature, society is growing in such a fashion that there is a certain amount of pressure created. This pressure can often drive and sometimes even force people to learn technology.
With the many positive effects of using the internet for research come negative aspects as well. Even with the decreased prices of computers over the years, they still are expensive to some families. The cost of the internet, while relatively cheap, can still be over a family’s spending budget. These are factors that are hard to escape when referring to the digital divide. As prices continually fall, the distance of the digital divide between low-income families and those who can afford these technologies decreases.
While it has been found that current college students have good study habits, they are easily distracted. The internet is a great source of information, but the vast amount of content online can be very distracting. With the internet being such a strong research source for people who were born in the 80’s and 90’s, people of this generation often use the internet for other aspects as well. These aspects include popular applications such as instant messaging, Facebook and MySpace. Along with social interactions, the internet can facilitate nearly any hobby. With things like this at a fingertip away, internet users can quickly become distracted. The internet provides a wealth of access to things other than simply education purposes. It is a strong source of other content such as entertainment and music. Computers provided with word processing software such as Microsoft Word help in a student’s paper writing ability. Software such as this is easy to use, but it is highly recommended to have good typing skills because this alleviates a lot of time. Typed papers are easier for students to edit and easier for teachers to grade. Word processing software has replaced traditional typewriters. But along with typed papers comes the ability to plagiarize. Plagiarism has become a major problem due to the “cut/paste” tools provided. Although, while students can simply copy stolen content from the web and hand it in as their own, teachers now have software that can track plagiarism. Other forms of cheating can also be found on the internet. Students are capable of downloading “solution manuals” off the internet which can help in subjects such as math. Cheating has slightly been facilitated by the internet but it is the student who needs to learn how to use technology for the right reasons.
Although there are positive and negative impacts from the internet, the positive ones far outweigh the negatives. The internet has become the student’s friend because of its relative ease and vast library of content. It has taken much of the pain out of research papers, but it has also created more “out of the classroom” homework assignments such as online quizzes. As the digital divide decreases, more and more people will become fluent with information technology. Although this will take time, we live in a society that makes computers and the internet a part of life. These technologies are becoming a necessary skill to have for many jobs and it can make daily life more enjoyable.

Socializing the internet
More today than ever before, the internet has become a popular resource for connecting people through online networks. Social networks such as MySpace and Facebook have become widely popular around the world in connecting people from all walks of life. Websites such as these allow for people to keep in touch with existing friends and they also provide the ability to create new contacts as well. Wherever there is access to the internet, social networks are able to provide a digital communication tie to others.
Facebook began in 2004 on the campus of Harvard, but spread to 2,000 more schools within a year. In 2006, Facebook began allowing high school students and businesses to begin joining the Facebook social network. “More than half (55%) of all of online American youths ages 12-17 use online social networking sites” (Electronic). Social websites such as Facebook have grown rapidly over the past few years. In “2007 Facebook was reported to have more than 21 million registered members generating 1.6 billion page views each day” (The Benefits). For many, logging onto Facebook has become a typical daily routine. It is reported that at least two-thirds of all users log onto Facebook for about 20 minutes everyday (The Benefits). Social networking has many positive effects for its users as well as a few negative effects.
The positive effects of social networks such as Facebook include its ease of use and its convenience. You can keep in contact with someone much easier and the search utility on Facebook allows you to reconnect with past friends. Anyone with a Facebook profile can be found simply by typing in their name. After finding the person, simply request to add this person as a friend and all the work is done. Even though social networking websites seem like a perfect communication tool, there are multiple negative impacts of using these applications.
While Facebook profiles often always have user’s pictures, it also has the option for the user to provide more personal information such as their home location, phone number, and class schedule. This information can be used in the wrong manner against an unexpecting victim. It only takes one person with a grudge to turn someone’s life upside down. Someone else who is another potential threat to Facebook users is known as the “Facebook stalker”. The Facebook stalker is someone who becomes obsessed with a particular person and constantly views someone’s profile and pictures just to see what he or she has recently been up to. Generally, this occurs after a girlfriend-boyfriend break up. Businesses use Facebook as a research tool for looking up employees. This allows employers to take a quick look into the personal life before hiring new workers. This could be a serious downfall during the employment process for students because many college student profiles contain many pictures including things like drinking and smoking. But, students have the ability to restrict access to outside viewers. To stay on the safe side, it is recommended to either take down offensive images or to add restrictive settings. As a student at Ohio State, I have even heard campus career services recommend making changes to our profiles in order to not allow employers to view such things.
Studies have shown that the majority of Facebook users have a lower GPA than those who do not use it. Facebook can become a major distraction when using the internet. Since it is generally apart of most student’s daily routine, it is easy to become intrigued by additions to others profiles such as new pictures. It is much more exciting to take a look at some pictures from the party last weekend than it is to prepare for the upcoming exams. Facebook has recently decided to include the option of adding integrated applications such as Bumper Sticker, Naughty Gifts, Groups, Graffiti and NCAA March Madness Bracket. There are endless time wasting opportunities such as these on Facebook.
Facebook is a great way to connect with other people interested in specific topics. “Groups” allow students to join together to make others aware and discuss something in particular. Recently with upcoming presidential election, groups dedicated to a particular candidate have become widely popular. Its way a to show others who you support and a way to show who you do not support. For example, I joined the group “Stop Hillary Clinton: (One Million Strong AGAINST Hillary)” and it currently contains over 905,000 Facebook members. Other types of groups on Facebook include ones called “I love the Mirror Lake Ducks” and “Hell yea I use Coinstar on a regular occasion” which are essentially useless with providing anything valuable.
MySpace.com and primarily Facebook.com are two websites that are popular with all demographics but are heavily focused towards teenagers and college students. “MySpace and Facebook combined are reported to cover more than 85 percent of all students in high school through college. They are connecting to each other-and not just casual connections but sustainable, global connections for life” (Electronic). As a college student, I have a Facebook profile and I cannot think of anyone my age that does not have their own. Facebook is widely popular as a way of leaving messages with friends and as a way of sharing pictures. It is definitely a popular trend in today’s culture and it is not likely to change anytime soon.
