SEARCH ENGINE vs PORTAL

Web Search Engine

• a program that searches documents for specified keywords and returns a list of the documents where the keywords were found.
• provide an interface to search for information on the worldwide web
• a program that indexes documents, and then attempts to match documents relevant to a user's search requests.
  The term search engine is most commonly used to refer to Web search engines, although other types of search engines exist. Web search engines attempt to index a large portion of pages on the World Wide Web. Other search engines are topic-specific, region-specific, and even site-specific.
• they index millions of sites on the Web, so that Web surfers like you and me can easily find Web sites with the information we want. By creating indexes, or large databases of Web sites (based on titles, keywords, and the text in the pages), search engines can locate relevant Web sites when users enter search terms or phrases.
• popular web search engine: Google Search, Live Search, Yahoo! Search

Web Portal

• a Web site or service that offers a broad array of resources and services, such as e-mail, forums, search engines, and on-line shopping malls.
• is a site that functions as a point access to information on the worldwide web
• a site featuring a suite of commonly used services, serving as a starting point and frequent gateway to the Web.Web portal services often include a search engine or directory, news, email, stock quotes, maps, forums, chat, shopping, and options for customization. These are only some of the most frequently offered services; large portals often include dozens or hundreds of bundled services.
• portals typically include search engines and large directories of websites. Most large portals have millions of Web pages indexed for visitors to search though. They also have large directories of Web sites, which are categorized by topic. Though the primary purpose of a portal is to find other sites for you, many now include a lot of information within their own sites.
• popular web portals: Google.com, MSN.com, Yahoo.com

Internet: Now and Then

OVERVIEW

Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol. Although the basic applications and guidelines that make the internet possible had existed for almost a decade, the network did not gain a public face until the 1990s.

Tim Berners-Lee, English Scientist who invented the Web along with the HTML tool that allowed a person to write a web page in 1989.

The internet is a collection of interconnected computer networks linked by copper wires, fiber-optic cables, wireless connections and etc. In contrast, the Web is a collection of interconnected documents and resources, linked by hyperlinks and URLs.

APPLICATION

Electronic Mail. The concept of sending electronic text messages between parties in a way analogous to mailing letters or memos predates the creation of the Internet.

Remote Access. The internet allows computer users to connect to other computers and information stores easily, wherever they maybe across the world.

File Sharing. A computer file can be e-mailed to customers, colleagues and friends as an attachment.

Streaming Media. Many existing radio and television broadcasters provide Internet 'feeds' of their live audio and video streams.

Voice Telephony. VoIP stands for Voice over IP, where IP refers to the Internet Protocol that underlies all Internet communication. This phenomenon began as an optional two-way voice extension to some of the Instant Messaging systems that took off around the year 2000.

FUTURE TRENDS

Semantic Web. It's about making the Web more 'intelligent', or as Berners-Lee himself described it: computers "analyzing all the data on the Web ‚the content, links, and transactions between people and computers."

Artificial Intelligence. AI means making intelligent machines, to test a machine's capability to participate in human-like conversation.

Virtual Worlds. Looking at Korea as an example, as the 'young generation' grows up and infrastructure is built out, virtual worlds will become a vibrant market all over the world over the next 10 years.

Mobile. In 10 years time there will be many more location-aware services available via mobile devices.

Online Video/Internet TV. It's fair to say that in 10 years time, Internet TV will be totally different to what it is today. Higher quality pictures, more powerful streaming, personalization, sharing, and much more - it's all coming over the next decade.
