Editor's Notes

• #5: LAN A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines. WAN A computer network that spans a relatively large geographical area. Typically, a WAN consists of two or more local-area networks (LANs). Computers connected to a wide-area network are often connected through public networks, such as the telephone system. They can also be connected through leased lines or satellites. The largest WAN in existence is the Internet. Extranet A buzzword that refers to an intranet that is partially accessible to authorized outsiders. Whereas an intranet resides behind a firewall and is accessible only to people who are members of the same company or organization, an extranet provides various levels of accessibility to outsiders. You can access an extranet only if you have a valid username and password, and your identity determines which parts of the extranet you can view. Intranet A network based on TCP/IP protocols (an internet) belonging to an organization, usually a corporation, accessible only by the organization's members, employees, or others with authorization. An intranet's Web sites look and act just like any other Web sites, but the firewall surrounding an intranet fends off unauthorized access. ethernet is a family of computer networking technologies for local area networks (LANs). What is interplanetary network or InterPlaNet?

• #11: How is information accessed on the internet/web
• #15: How is information accessed on the internet/web
• #23: Amazon search, Blekko, Volunia, Yebol, and blackie.com
• #24: Disadvantages of static website: Any personalization or interactivity has to run client-side, which is restricting. Maintaining large numbers of static pages as files can be impractical without automated tools. A Rich Internet Application (RIA) is a Web application that has many of the characteristics of desktop application software, typically delivered by way of a site-specific browser, a browser plug-in, an independent sandbox, extensive use of JavaScript, or a virtual machine. Created with Adobe flash, Adobe flash builder, silverlight, JavaFX Open Laszlo and HTML 5
• #27: Communication on the internet is based on an architecture described as client-server architecture. One popular architecture used by web developers is known as the N-tier architecture. The N represent the Number of phases the development will have to go through. Typically, developer adopt these three phase namely: Presentation Tier Business/logic Tier Data Tier
• #29: Simple or Plain text editors: sublime text(cp) Atom (cp) Eclipse/ Aptana (cp) TextMate(OSX) coda (OSX) Espresso (OSX) chocolate (OSX) Komodo IDE (cp) Notepad++ (w) PSPad(w) WYSIWYG offline editors e.g. Adobe Muse, Adobe Dreamweaver, Adobe Edge, Coffee Cup WYSIWYG online editors e.g. JS fiddle, JS Bin Code Pen, ICEcoder, Divshot, Codio, codeanywhere, textarea (browser based cp) CodeMirror (BB cp) Template-based editors: HTML 5 Boilerplate, Zurbs Foundation, Twitter Bootstrap, Wordpress *cp = cross platform *BB = browser based *w = windows *OSX = Mac
• #31: Web 1.0 generation - is about connecting information (Info-Centric). The focus of Web 1.0 was primarily on building the web, making it is accessible, and commercializing it for the first time. This generation of Web provides opportunities for people to communicate with other people and businesses using their personal computing devices. The users of this first generation of the Web go through the web sites of businesses to find the information they want and use the email to communicate with people they know. However, the machine and its ability to connect remains at the core of this web generation.
• #32: Web 2.0 generation is about connecting people (People-Centric) together, participation, interaction and collaboration. The Web in this generation provides the application platform that complements the personal computer used for communication in the earlier generation. The support of an application platform and the ability to create, store and execute applications, has resulted in a technical as well as a social revolution in the use of web. The blogs, wikis, social networks, and RSS feeds, as well as the continued growth Web 2.0 applications have been popular and used in past few years. Web Services (WS), referred to earlier, are a successful application of web technology in the generation of Web 2.0. Users cannot only get information from the business but also get services and pay for them across the net. Furthermore, people-to-people interaction moves from communication using emails to creation of social networks and groups resulting in sharing of information, thoughts and knowledge across the web.
• #33: This Web 3.0 is a convergence of several new technologies and service, such as mobility connectivity, network computing, services business, open technologies and open identity
