4. A brief History
PDF (Portable Document Format) is a file format
developed by Adobe as a means of distributing
compact, platform-independent documents. It is
superficially similar to HTML; a PDF document
may contain images and text, as well as
hyperlinks. However, as PDF is based on a
variant of PostScript, each document is self-
contained, packing text, graphics, and fonts into
a single file.
