http://cdn1.1stwebdesigner.com/wp-content/uploads/2011/03/collection-of-information-from-multiple-resources4.png

Information technology has helped the world with the same level. Without his contribution, there is no doubt that we now do not get this "technical world" or. But even if some people raise a number of statements (which may be unfounded) that the information technology (IT) are taking away the privacy of ordinary people and breaking international reputation of the world wide human knowledge.

So let some positive aspects in this article (OPR) and poorEffects (v) Information Technology in places. According to the definition of a Google service, it is said-

"The branch of engineering that get on the use of computers and telecommunications, and store and transmit information." – Definition of Google.

Therefore, the definition in that it provides, it is clear that this is "the branch of technology that helps us communicate with each other, technology transfer individual knowledge, and our store with your computer and other modernmeans Information Technology. "

Information Technology Pro

1. The world has the flexibility

we do or what to think, plan employees, colleagues and friends are our shared with. Internet technology, this system has a high degree. The idea of ​​the telephone (Alexander Graham Bell) was changed and made like mobile phones, to increase the flexibility in communication and talk to our dear comrades, wheneverDemand!

2. The sense of responsibility has increased

Let 'Barack Obama President of USA, "as the figure. The use of networking sites (Twitter and Facebook), blogs, social bookmarking, the LEADER approach in the world, if necessary, we can send messages and updates that are ( or will be made by us) will be 'within a very short period of time.

3. Just to think, and developments in the transport sector

Of thought and research, weResources need to find out what people thought of our past, which the quotations that have left us (information theory + +). We can use it with a single click in the search engines (especially Google ™, Yahoo) to find. By a clear cut idea, we have the opportunity to help the world with new ideas and technological inventions and to share what we learned during our lives.

And over the centuries has contributed to a widening of the transport strategy that helps us attend to one place to anotherof (roads, highways, air, water and sky!)

4. This allows you to save thousands of lives every day

Then, from the point of entry I hope you understand me relate to the development of the medical field. Every day people relief with the perfect use of medicine, hospital technology, by adding (X-rays, laser treatments) and more in the queue. With the combination of World Health Organization, several life-threatening diseases to overcome and be expelled from the newly establishedCountries rapidly and the plans and ideas.

5. Increase the sense of human rights

Technology can remember those of our human rights, basic needs and updates made ​​available to or around the world where it is necessary to help alleviate. During earthquakes, floods, horrible, that during the cooperation is necessary on the World Wide Web Help us to collect the donation of a set.

They can not understand, it's about good and bad sides of the Information and Technology ManagementWithin a page and how, as he mixes with all aspects and angles of our lives. Rather, we have seen in side effects bad side (cons) that led in the sectors of human society.

Information Technology Cons

He pulled the privacy of individuals

As the IT sector the hearts of people around the world have wined. People are here to share and store any kind of information, the date of the individuals in their private hard drives and onlineDatabases. But because of some computer criminals, is not as safe, both online and offline. If someone has a little "sloppy, he / she has to pay high. (E 'heavy).

The online community is not safe for the family more

Children under the age can often share cell numbers, e-mail contact, which can be manipulated by people and pass it to the criminals who harm a blueprint of the company. And people lose their privacy and credit card payments from otherProcessing options. Again, there are several Web sites created perverse that a child can be worn under the age of eighteen in a different place – that the nation is to bring Harms.

E 'intention to harm a human Natural Power

People should be the best of all creations (in Islam). We can imagine, to collect the human principles (ethical knowledge) and then working relationships with friends and family. But because of the harmful aspects of the (IT) People are always fullbased technology. And it can bring great harm to society by taking away the thoughts and ideas of natural organic.

You can bring effective administration without World Destruction

This is something more that I write, having regard to the various science-fiction. Great scholars have, even if the problem with wisdom. Up to now (people) we are holding a prominent place in the world and the management of information technology. But come one day, when theThe technology is for us to manage all aspects. It is possible that we will probably convert the slaves of technology.

So from this I am not trying to say that the technology to bring harm here, just because I have a technological man over 24 hours of navigation computer and talk on the phone itself. But as part of human society, we must take a look at both sides.

How Do Web Search Engines Work


Search engines are the key to finding specific information on the vast expanse of the World Wide Web. Without sophisticated search engines, it would be virtually impossible to locate anything on the Web without knowing a specific URL. But do you know how search engines work? And do you know what makes some search engines more effective than others?
When people use the term search engine in relation to the Web, they are usually referring to the actual search forms that searches through databases of HTML documents, initially gathered by a robot.

There are basically three types of search engines: Those that are powered by robots (called crawlers; ants or spiders) and those that are powered by human submissions; and those that are a hybrid of the two.
Sponsored10 New Reasons to Virtualize Your Infrastructure: The cost savings that comes with virtualization makes an easy selling point, but there are other reasons the technology makes sense.
Crawler-based search engines are those that use automated software agents (called crawlers) that visit a Web site, read the information on the actual site, read the site's meta tags
and also follow the links that the site connects to performing indexing on all linked Web sites as well. The crawler returns all that information back to a central depository, where the data is indexed. The crawler will periodically return to the sites to check for any information that has changed. The frequency with which this happens is determined by the administrators of the search engine.
Human-powered search engines rely on humans to submit information that is subsequently indexed and catalogued. Only information that is submitted is put into the index.

Chapter 7

Flooding in Thailand


There are still plenty of ordinary Australians desperate to help, but not sure how to . However, it is still very difficult for individuals, many of whom live in or near flood affected areas, to find out the best way they can help and support their local community.

if you have muscle or manpower to volunteer you can register with Volunteering QLD who are coordinating volunteer efforts in Queensland, but there are plenty of other ways that you can provide practical, hands on support for flood victims. It is often the simple, seemingly little things, that can make the biggest difference in supporting those affected by floods.

An innovative new service called HelpOut, has been established specifically to connect those people who need help with those who are able to provide help. This service allows individuals living in or near flood affected communities, to list the types of help they can offer. Perhaps more importantly though, HelpOut also allows those people directly affected by flood, many of whom are in desperate need of assistance, to specify exactly the type of assistance that they need.

HelpOut allows people to search by location (town, suburb or postcode), and presents offers and calls for help on a map – so it is very easy to see what help is available (or need) in specific areas.

The Library of Congress Classification (LCC) is a system of library classification developed by the Library of Congress. It is used by most research and academic libraries in the U.S. and several other countries, for example, Australia and Taiwan, R.O.C. It is not to be confused with the Library of Congress Subject Headings or Library of Congress Control Number. Most public libraries and small academic libraries continue to use the Dewey Decimal Classification (DDC).

The Dewey Decimal Classification (DDC, also called the Dewey Decimal System) is a proprietary system of library classification developed by Melvil Dewey in 1876.[1] It has been greatly modified and expanded through 23 major revisions, the most recent in 2011.[2] This system organizes books on library shelves in a specific and repeatable order that makes it easy to find any book and return it to its proper place. The system is used in 200,000 libraries in at least 135 countries.[3][4] A designation such as Dewey 16 refers to the 16th edition of the DDC.
