What is a PDF document???

PDF: Short for Portable Document Format, a file format developed by Adobe Systems. PDF captures formatting information from a variety of software application programs – including Microsoft Word & Excel, Word Perfect and others, so that it is possible to send formatted documents and have them appear on the recipient's monitor or printer as they were intended. So they are welcome to open, read, save & print the documents – but they cannot change them.. When you and I visit websites, such as the registry of motor vehicles, IRS, medical, insurance and other such websites, forms we download are often done in PDF format so that we can view them, save them, print them as we need them – we just couldn’t modify them or change any information on them. In order to view them however, we need to have the Adobe Reader, which is a free application distributed by Adobe Systems

What are Plug-Ins?

PLUG-INS are small computer bits of software, typically free, that let you view a document, interact with an image, listen to music or watch a video. When you have the right PLUG-IN software application, you can view different information formats in your browser window on your computer, so that you can listen to your favorite song, see animations and videos and read documents that are secured in PDF format. Example: if you want to play a game that uses Shockwave and you don't have it on your computer you'll be prompted to install it. Once installed, you usually have to restart your browser or even your operating system to make a plug-in active. What popular PLUG-INS do:

Real Player - Popular sound and video player

Flash Player - Used for animations and games

Shockwave Player - Used for 3d animations and games

Cortona - Used for viewing and interacting with virtual environments

Acrobat - This is a reader, that is needed to look at PDF files

QuickTime - used for high quality video

Windows Media Player - Microsoft's media player - plays sound and video
