I have an exam of Deploying Web Technologies on 16 Jan and I am searching for some problems. Here I put a question related to web. I search for the answer on Internet but yet not success. The question is; Why might some sites (or parts of sites) be delivered as .pdf, rather than .doc or .html files ?

Answer 1

PDFs have a few advantages for certain types of content:

• Directly printable - Sizes, fonts, graphics will all render the same on all devices for print. This is important for printable forms and publications.
• Universal - There are PDF readers available for almost any platform, including ancient mobile devices.
• This is usually the published non-editable version of the document.

A Word Document file has a couple interesting characteristics:

• Intended for printing
• "Original" form of document in many cases
• Easily edited later
• Many (most?) people don't have Microsoft Word. OpenOffice and others can often open Word documents, but there are incompatibilities where some documents render strangely.

HTML works in all the browsers. When done correctly, it will also print consistently in most browsers. In my experience, when people link to PDFs it is generally out of laziness. The folks writing the content don't always know HTML and the web person will often just post a PDF and link to it.

Answer 2

I hope this is a joke, but it's because the file being loaded is actually a PDF file which the browser (probably chrome or firefox) is rendering for you to read. .DOC being a word file is not however, and you must download that one to read it.
