PDFs: Most computers will already be able to view PDFs, but if your's can't, simply download the free Adobe Acrobat Reader. You will need to install it and restart your computer. Find out more about viewing a PDF on an iPad.
Zip files: Windows Vista and XP and Mac OS X can open zip files without any other software. If you are using another operating system, you may need to download a utility to open a zip file.
Different browsers handle downloads differently. Some will automatically display PDF in the browser window, some may download the file to a default location on your computer, some may do both. There are two ways to make sure you can save a file where you want it on your computer.
If you don't have a right-click button, you can hold down the control key and click your mouse button.
