A document file format developed by Adobe. Short for "Portable Document Format" which pretty much describes its purpose.
It is a very popular file format for the following reasons
> PDF documents are almost always Read-Only. This makes it a very convenient format to distribute documents without the worry of content being changed
> A PDF prints out easily and accurately without messing about with formatting.
> A free 'Reader' utility called 'Acrobat Reader' allows anyone to view the document, so no expensive software is needed just to view documents.
> PDF is widely supported in the professional print industry so if you are an author of content, then buying the full authoring application is a sensible investment.
> There are free 'Print Drivers' available for applications such as Word that allows you to create a PDF file simply by selecting it as one of your printers. It is not so good as the proper Adobe authoring software, but good enough for simple documents.
