Questions:

->>>What are the advantages of using search engines??
>>>Search engines provide some popular ways of finding information on the Internet. There is a wide variety of search engines and features. Some search engines are on specific websites, allowing visitors to the site to search for specific words or phrases. Others are broader in scope.

->>> What are the disadvantages of using search engines??
>>> Regardless of the growing sophistication, many well thought-out search phrases produce list after list of irrelevant web pages. The typical search still requires sifting through dirt to find the gems.

->>>Compare and contrast individual search engines and search mete search engines.>>> Though there are dozens of useful meta search engines, Info Space is the industry gorilla, operating the four arguably best known and most heavily used properties. Dog pile and Met crawler are the two best known Info Space meta search engines. Less well known is that Info Space purchased the Excite and WebCrawler properties when Excite failed, and quietly re-engineered their back ends as meta search engines. In the past, Search Engine Watch has been critical of the Info Space services (see "Meta Search or Meta Ads" below). But the company has overhauled its business model during the past six months, and has renewed its commitment to providing quality search results.

->>>When is it appropriate to use a search engine?
>>> A web search engine is designed to search for information on the World Wide Web and FTP servers. The search results are generally presented in a list of results and are often called hits. The information may consist of web pages, images, information and other types of files. Some search engines also mine data available in databases or ope directories. Unlike web directories, which are maintained by human editors, search engines operate algorithmically or are a mixture of algorithmic and human input.

Question3

->>>What is an invisible Web or “Deep Web”?>>> The Deep Web (also called Deepnet, the invisible Web, DarkNet, Undernet, or the hidden Web) refers to World Wide Web content that is not part of the Surface Web, which is indexed by standard search engines. Mike Bergman, credited with coining the phrase, has said that searching on the Internet today can be compared to dragging a net across the surface of the ocean: a great deal may be caught in the net, but there is a wealth of information that is deep and therefore missed. Most of the Web's information is buried far down on dynamically generated sites, and standard search engines do not find it. Traditional search engines cannot "see" or retrieve content in the deep Web – those pages do not exist until they are created dynamically as the result of a specific search. The deep Web is several orders of magnitude larger than the surface Web
->>>How do you find an Invisible Web?
>>> Is it some kind of Area 52-ish, X-Files deal that only those with stamped numbers on their foreheads can access? Well, not exactly. The term "invisible web" mainly refers to the vast repository of information that search engines and directories don't have direct access to, like databases. Unlike pages on the visible Web (that is, the Web that you can access from search engines and directories), information in databases is generally inaccessible to the software spiders and crawlers that create search engine indexes.

1. What is a web browser? How does it work?
>>A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web.
2. What is a bookmark?
>>A bookmark is a page keeper. A reader inserts a bookmark into the pages of a book when he or she stops reading. This way when it's time to read again, the reader can open the pages where the bookmark is to find the place in the book where he or she left off at rather than trying to remember the page number.
3. What is the purpose of a web [browser] cache?
>> A web cache is a mechanism for the temporary storage (caching) of web documents, such as HTML pages and images, to reduce bandwidth usage, server load, and perceived lag. A web cache stores copies of documents passing through it; subsequent requests may be satisfied from the cache if certain conditions are met.
4. What is a web [browser] plug-in?
>> In computing, a plug-in(or plug-in) is a set of software components that adds specific abilities to a larger software application. If supported, plug-ins enable customizing the functionality of an application. For example, plug-ins are commonly used in web browsers to play video, scan for viruses, and display new file types.
5. Choose three types of web browsers and answer the following questions for each browser.
  • How do you set homepages?
  • Click on your Internet Explorer icon; you'll find this in your Start menu, or the toolbar at the bottom of your desktop window. Type in "Google" to IE's search box at the top of the browser window (this is just an example, you can use any website that you want). Arrive at Google search engine home page. Go to toolbar at the top of browser, and click on "Tools", then "Internet Options". At the top of the pop-up, you'll see a "Home Page" box. The address of the site that you are currently at (http://www.google.com) is there. Press the "Use Current" button to specify this page as your home page.
  •  
  • How do you clear the cache?
  • Although it's not required by all browsers, restarting your browser after clearing the cache is a good idea. If you're using Explorer 4.x or Explorer 5.x it's better to restart the computer as well.
  •  
  • How do you install a plug-in?
All you need to do is to copy (or drag) the file into the Plug-Ins sub-folder of the Photoshop folder. For example, for Photoshop CS3 it's typically located at:
Program Files\Adobe\Adobe Photoshop CS3\Plug-Ins (for Windows) or
Applications\Adobe Photoshop CS3\Plug-Ins (for Mac OS).

                                                "Impact of the Internet in our world today"

The Internet has forever changed the world in both positive and negative ways. The Internet enables one to find information any time of day, as well as provides convenience with regard to such activities as paying bills. On the other hand, the accessibility of pornography and false information and the occurrence of pop-ups on the Internet serve as negative effects. The Internet today is in many ways seen as an essential to life. It is used in the workplace, school and home. With the invention of the Internet the world was forever changed in both good a bad ways. Many positive results have come from the invention of the Internet. One positive that has resulted from the Internet is the fact that you are always able to access research information anytime of the day or night. The Internet has every kind of information that you could possibly want, there is everything from how-to's to high level medical research information.
2. ISOC -> The User Centric Internet (UCI) is a new ISOC Public Policy program designed to reassert, in debates and discussions related to the future of the Internet, the importance of the design values and fundamental principles that have underpinned the Internet's success.ISOC will continue to play its central role in the Internet governance discussions ensuring that developments do not imperil or hinder the Internet's development, deployment, administration, or management. ISOC will show leadership in governance discussions, particularly in the Internet Governance Forum.ISOC will operate collaboratively and inclusively, working with governments, national and international organisations, Civil Society, the private sector, and other parties to reach decisions about the Internet that uphold our core values. In this work, ISOC will be guided by our belief that the future of the Internet depends upon preserving the ability to connect, speak, innovate, share, choose, and trust.
3.IAB -> The Interactive Advertising Bureau (IAB) is comprised of more than 500 leading media and technology companies who are responsible for selling 86% of online advertising in the United States. On behalf of its members, the IAB is dedicated to the growth of the interactive advertising marketplace, of interactive’s share of total marketing spend, and of its members’ share of total marketing spend. The IAB educates marketers, agencies, media companies and the wider business community about the value of interactive advertising. Working with its member companies, the IAB evaluates and recommends standards and practices and fields critical research on interactive advertising. Founded in 1996, the IAB is headquartered in New York City with a Public Policy office in Washington, D.C.
4.IESG ->
The IESG is responsible for technical management of IETF activities and the Internet standards process. It administers the process according to the rules and procedures that have been ratified by the ISOC trustees [see RFC 2026/BCP 9, The Internet Standards Process].  The IESG is directly responsible for the actions associated with entry into and movement along the Internet "standards track," including final approval of specifications as Internet Standards.
The IESG consists of the Area Directors (ADs) who are selected by the Nominations Committee (NomCom) and are appointed for two years. The process for choosing the members of the IESG is detailed in RFC 2727/BCP 10, "IAB and IESG Selection, Confirmation, and Recall Process: Operation of the Nominating and Recall Committees."
5.IRTF->The IRTF is a composed of a number of focused and long-term Research Groups. These groups work on topics related to Internet protocols, applications, architecture and technology. Research Groups have the stable long term membership needed to promote the development of research collaboration and teamwork in exploring research issues. Participation is by individual contributors, rather than by representatives of organizations.
The IRTF is managed by the IRTF Chair in consultation with the Internet Research Steering Group (IRSG). The IRSG membership includes the IRTF Chair, the chairs of the various Research Groups and other individuals (“members at large”) from the research community selected by the IRTF Chair.
The RFC Editor publishes documents from the IRTF and its Research Groups on the IRTF Stream (RFC 5743).
6.IETF->
The goal of the IETF is to make the Internet work better.                                
The mission of the IETF is to make the Internet work better by producing high quality, relevant technical documents that influence the way people design, use, and manage the Internet.
7. IANA ->
The Internet Assigned Numbers Authority (IANA) is the body responsible for coordinating some of the key elements that keep the Internet running smoothly. Whilst the Internet is renowned for being a worldwide network free from central coordination, there is a technical need for some key parts of the Internet to be globally coordinated – and this coordination role is undertaken by IANA.
Specifically, IANA allocates and maintains unique codes and numbering systems that are used in the technical standards (“protocols”) that drive the Internet.
8.InterNIC->By the 1990s, most of the growth of the Internet was in the non-defense sector, and even outside the United States.[5] Therefore, the US Department of Defense would no longer fund registration services outside of the mil domain. In 1993, the US National Science Foundation, after a competitive bidding process in 1992,[7] created the Internet Network Information Center, known as InterNIC, to manage the allocations of addresses and awarded the contract to three organizations: Network Solutions provided registration services, AT&T provided directory and database services, and General Atomics provided information services.[8] Later, General Atomics was disqualified from the contract after a review found their services not conforming to the standards of its contract.[9] General Atomics' InterNIC functions were assumed by AT&T. AT&T discontinued InterNIC services on March 31, 1998 after their cooperative agreement with NSF expired.[10]
9.ICANN-> To reach another person on the Internet you have to type an address into your computer - a name or a number. That address has to be unique so computers know where to find each other. ICANN coordinates these unique identifiers across the world. Without that coordination we wouldn't have one global Internet.
ICANN was formed in 1998. It is a not-for-profit public-benefit corporation with participants from all over the world dedicated to keeping the Internet secure, stable and interoperable. It promotes competition and develops policy on the Internet’s unique identifiers.
ICANN doesn’t control content on the Internet. It cannot stop spam and it doesn't deal with access to the Internet. But through its coordination role of the Internet's naming system, it does have an important impact on the expansion and evolution of the Internet.
