2.1.4        Webpage Preview

The Preview view shows an approximate view of what the page would look like in a Web browser. Things like dashed lines for tables won’t appear in this view.

2.2.1        Publishing WebPages

Publishing WebPages is the process of copying all of the files to a remote location on a server.

2.2.2        The importance of publishing the webpage

The WebPages become available to other people either in World Wide Web (internet) or in Local Area (Intranet). This will enable targeted audience to access information from the website. People may download the pages they need, plus all of its associated files like forms, pictures, and so on.

2.2.3 Procedure of transferring webpage to the web saver

  • A Web server is a computer that runs special serving software. That software “serves” HTML pages and associated files when requested by a client, such as a Web browser.
  • When you use your browser to visit a site, you typically make your request by entering a URL (for example: http://example.microsoft.com). A URL is a Uniform Resource Locator. It’s simply an address for a file on the Web.
  • When the server receives your request, it serves or downloads the page you need, plus all of its associated files like pictures, and so on.

Web server details

  • The URL for your site may be determined by your hosting company, but you can also register your own unique URL.
  • The correct file name for your home page; home pages can be named index.htm, index.html, default.htm, or default.html depending on the kind of server your site will reside on.
  • User name and password; these are often needed to publish pages to a remote server.
  • Server restrictions; the total file size of your site’s files may not be able to exceed a certain size or other restrictions to use certain

2.2.3        The difference between webpage and website

A Webpage is document on the World Wide Web. A Webpage consists of an HTML file, with associated files for graphics and scripts, in a particular directory on a particular machine (and thus identifiable by a URL). Usually a Web page contains links to other Web pages.

A Website is group of related HTML documents and associated files, scripts, and databases that is served up by an HTTP server on the World Wide Web. The HTML documents in a Web site generally cover one or more related topics and are interconnected through hyperlinks. Most Web sites have a home page as their starting point, which frequently functions as a table of contents for the site. Many large organizations, such as corporations, will have one or more HTTP servers dedicated to a single Web site. However, an HTTP server can also serve several small Web sites, such as those owned by individuals. Users need a Web browser and an Internet connection to access a Web site.

Typically, you can create a Web site on your local computer. However, the site won’t be available to other people until it is eventually published—or copied—to a Web server.

2.2.5 Access information on a website

Where to find a Web server

  • Where do you find a Web server? That depends on how widely available you want your site to be.

–              World Wide Web    If you want your site to be available on the World Wide Web, you need to find a company that offers space on their server. Companies like these are typically called Web site hosting companies. To find a Web site hosting company, search the Internet using your favorite search engine or use the URL. This will be done in the practice session at the end of this lesson.

–              Intranet    If you want your site to be available only to your company’s intranet, then your IT department may have a server that you can use. It is also possible that your very own computer may be able to be configured as a Web server.

How to put your Web site on a Web server

  • To put your site on a Web server, you publish it. Publishing generally means copying all of the files to a remote location on a server. In most cases, the remote location is either an HTTP path or an FTP path. The path you use depends on what technologies your server supports.
  • FTP (the File Transfer Protocol) is a popular way to upload files to a remote server. If your server supports FTP, you would publish to an FTP location. For example, ftp://ftp.MyServer.com/myFolder. (Please note that even though you publish to an FTP path, you would still visit the site using an HTTP path in your browser.)
