Although the words "internet" and "world wide web" or "web" for short get tossed around as if they are one and the same, each has a particular function that is best described by saying that the web is an aspect of the internet. Where the internet allows files, documents, etc. to be shared between computers in a community type environment, the web is one channel that allows information to pass between computers. The web uses hypertext links to transfer various bits of information across the internet, and thus has its own special language to do so. This is called HTML, or hypertext markup language. Thus, in short, the internet can exist without the web, but the web could never exist without the internet; the web is one aspect of the capabilities of the internet.
After looking at the Happy Cog website, one can begin to identify the HTML components of the page. While the overall design of the website is handled by the CSS aspect of the design, the structural elements of the page are handled by the HTML. Five of these components are:
1) The Happy Cog logo, which is a graphic element linked into the document.
2) The title of the page, "We are Happy Cog," which is likely handled with an <h1> tag.
3) The paragraph that describes the Zappos article, which is handled with a <p> tag.
4) The Facebook and Twitter buttons at the bottom of the homepage are handled by <href> tags that link the text to a specific webpage.
5) The bolded words in the paragraphs that say "read more" have more emphasis that is handled by an HTML tag that tells readers to click that particular word or group of words for more information or access to a link to a full article.
