INTRODUCTION:
PDF is a file format developed by Adobe
Systems in the early 1990s as a way to share documents, text, images. This file
format is used for presenting documents which are independent of application,
operating system, hardware, and software. It is an open standard for electronic
document exchange maintained by the international organization for
standardization (ISO). When documents, forms, graphics, web pages are converted
into PDF format, and they appear as printed text. For reading PDF files you
need to install the free Adobe Reader Software. Once you have downloaded the
Reader, it will automatically start up whenever you want to look at a PDF file.
These files are especially useful for documents such as magazine articles,
product brochures, or flyers in which you want to preserve the original graphic
appearance online.
