WEBSITE V.S. WEB PAGE

 Website

  • helps us to perform our tasks using internet as an enabling technology.
    • composed of hyperlinks and sometimes

      individuals, institutions, and business
      organizations.
  - consists of one or more web pages that
  refer to the individual links or pages of a
  website (acts like the pages of a book).

  - once a user clicks a link or presses a
  button on a website, it instructs the site to
  jump from one web page to another web
  page, thus changing the display on the
  computer screen.

 Web Page

  • can be either static or dynamic in nature.
  • these natures are identified by their method of displaying web pages when being requested or clicked by the user.

Types of Web Page:
a. Static Web Page
b. Dynamic Web Page

a. Static Web Page
• Characterized by their fixed content, which means that it shows the same content every time the web page is accessed.
• All the elements like textual information and multimedia content are hard-coded and embedded in the web page, making it difficult to update or modify.
• If the author of the website decides to make changes in one of its web pages, the whole site will be inoperable for a period to give way for the coding or updating of the content.

b. Dynamic Web Page
• Known for being changeable, which means that its content can change each time the web page is accessed.
• Elements like text, graphics, audio files, and videos are saved in the server, making it very easy to update.
• a user clicks a link that will show an explanation about the water cycle; the website will request the said multimedia content from the server, and from there, the server will post the video on the site.
• If the author notices an error on the information displayed on the website, he only has to upload the modified version of the text to the server and delete the one that contains the error.
