1. What are the advantage and disadvantage of using search engine?

The indexes of search engines are usually vast, representing significant portions of the Internet, offering a wide variety and quantity of information resources.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.

2. Compare and contrast individual search engines and search meta search engines?


The search engines give you some control over which search queries trigger your PPC ads. Google and MSN offer three options: Exact, Phrase and Broad Match. In general, Exact Match means your ad will only appear if a person's search query matches exactly with the keyword (or phrase) you bid on. With Phrase Match, your ad is eligible to be shown if the search query contains all the words in your keyword plus additional words before and/or after.

A metasearch engine is a search tool[1] that sends user requests to several other search engines and/or databases and aggregates the results into a single list or displays them according to their source.

The term "meta search" is frequently used to classify a set of commercial search engines, see the list of search engines, but is also used to describe the paradigm of searching multiple data sources in real time. The National Information Standards Organization (NISO) uses the terms Federated Search and Meta search interchangeably to describe this web search paradigm.

3. When it is appropriate to use search engines whet it is appropriate to use search engines subject directory?

There are many search engines and internet directories, but familiarizing yourself with several major ones will be enough to get your online research off to a good start. The main search engines included in this article are InfoSeek, Yahoo, Excite, HotBot, AltaVista, Lycos and LookSmart; LookSmart and Yahoo are actually large directories rather than true search engines.

4. What is an invisible web or deep web?

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,[1] 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.

5. How do you find an invisible web?

The Deep Web is a mammoth resource that is mostly untapped. Learn how to discover Deep Web resources with this comprehensive, ultimate guide to searching the Deep Web's goldmine of information. The Hidden Web, aka the Deep Web, aka the Invisible Web, is the part of the Web that can't be easily accessed with a simple search engine query. Learn more about the Invisible Web and how big this part of the Web is estimated to be.

6. Why are this web pages not available in search engines or subject directories?

The first two reasons (deep and big) are easy to change from the perspective of search engines. Many today go deeper into the directory structure and farther down the page than they used to. Pages without links are often of poor quality (hence no links), and so this is not a significant problem. They can still be included in most search engines by submitting the page. The next two reasons (robots excluded and protected) are not “problems”; if people don’t want others on their website, then search engines shouldn’t be going there. The last two reasons (non-HTML and dynamic) constitute what most people consider to be the invisible web, and more recently, exclusively the last reason. There are many pages on the web which are not in HTML. See Search by File Format for more on that. Google includes more non-HTML content than any other engine. There are millions of dynamic pages, many of which are exactly what you may be looking for, and many others of which are an infinite number of near-duplicate pages. Indexing dynamic pages has the potential to stall a search engine’s crawler, which is why most don’t do this. It is believed that Google index dynamic pages that it finds by following links from static ones, but does not follow links from dynamic pages themselves.

The web browser.

1. What is a web browser? How does it work?

A web browser is a program on your computer that allows you to visit website. You get your web browser by clicking on its icon, from there you enter web address, and the web browser just places the web pages for you. The web browser is the most important piece of software on your computer because every web pages runs through it.

As you already know, to view a web site or a web page in a browser, you would either type in the URL or click on a link and hit the go button. Now, the page you have asked the browser to display would probably be located on a Server computer far away.

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. Bookmarks save having to flip through the book and read sentences trying to find the exact place to re-start reading the book.

3. What is the purpose of a web [browser] cache?

The purpose of a web browser cache is that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the cache (cache hit), this request can be served by simply reading the cache, which is comparatively faster.


4. What is a web [browser] plug-in?

n 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. Well-known plug-ins examples include Adobe Flash Player and QuickTime.










Choose three types of web browsers and answer the following questions for each browser.
Microsoft Internet Explorer.
Mozilla Fire fox.
Google chrome.


How do you set homepages?
When you initially open up your Web browser, the very first page that you will see is called the "home" page. The home page is your jumping off point to the rest of the Web. You can specify absolutely any page on the Web as your browser homepage.
How do you customize search providers?
To add a provider to the Internet Explorer Instant Search box, click the provider's link below. You can set any of these as the default search provider by selecting the Make this default search provider check box in the Add Search Provider dialog box that appears when you click the link.
How do you clear the cache?
Every web browser stores a cache of the websites you visit e.g. HTML pages, to reduce bandwidth usage and server load. This is called the browser's cache. Clearing it occasionally can make some websites run smoother and free up space on your computers hard drive if it's running low.

    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 is common to everybody, Internet has a big impact to the society it's because the internet helps to deliver your message to the another country easily. It change the way we use computers, change the way we communicate example the VOIP voice over internet protocol like using yahoo. Of course changing information. the impacts are Online stores, paying bills on the internet, helps to improve out education. That's the Impact of the Internet.

   The Internet Society (ISOC) is a nonprofit organisation. An international organization that promotes Internet use and access. The Internet Architecture Board (IAB) is the committee charged with oversight of the technical and engineering development of the Internet. The Internet Engineering Steering Group (IESG) is a body composed of the Internet engineering task force (IETF). IRTF a research organization working on topics related to the evolution of the Internet.the Internet Assigned number Authority, an organisation that oversees IP address, Top-level domain and Internet protocol code point.The Internet Network Information Center, known as InterNIC, was the internet governing body primarily responsible for domain name and IP address. ICANN is responsible for managing the internet protocol address space.

      What made the internet reliable and efficient?

    For me, the internet is well organized for people. Its gives an information to us. It feels like one wire connecting directly to what ever we one, like listening music, watching movie, chat with friends. 

     What principles applied in the Internet that could also be beneficial in other areas?

The principle that we can applied in the internet are so many. change the way we communicate, even though were  a filipino the internet change the way we communicate to the others especially communicating in the other country. and also change the way we exchange information like online store etc. the benefits are we can watch movies, chatting with friends or a research that helps our studies. 

 Explain the TCP/IP Protocol Suite (Internet Model).

    As long as we agree, we can keep more devices and more network so that the whole world is connected. That's what internet is. IP protocols are the way why we can send a message easily from one place to another. By following the protocol the receiver devices how to put it all back together. like playing online games we can communicate to the other country playing with other country because of agreement. A network that shares together by the helps of protocol our message, picture etc will delivered well. Protocols are available to everyone.The Internet Protocol Suite consists of four abstraction layers. From the lowest to the highest layer, these are the Link Layer, the Internet Layer, the Transport Layer, and the Application Layer. The layers define the operational scope or reach of the protocols in each layer, reflected loosely in the layer names. Each layer has functionality that solves a set of problems relevant in its scope.
