What's the difference between a PDF and PDF/A document?

In general, there is no difference, but (rarely) professionals mean PDF document as a file related to PDF Standard, and PDF archive - a file related to PDF/A Standard.

Type on PDF: All You Need to Know

The file format is of the highest degree of complexity, or requires special workarounds to be used efficiently. Examples of these special problems include: When using OpenDocument format, you must not open the files with the same Windows/Unix command-line programs as PDF. OpenDocument format is not compatible to open in WordPerfect. When using Adobe PDF 1.4, there are significant, complex, extra tools required to create files, and some PDF documents need to be created within the context of existing file management systems. When using Acrobat 6.0 and later versions, files are not created within PDF files. This means you can not open your document as you would an open .DOC file. This list is not necessarily exhaustive. It covers the most common file formats that many users encounter. You could also create your own list. There are many good resources available on the web about file formats, and this list could be expanded.
