Let say I want to install Zip, IM Client and Firefox on my PC, the steps comparison on Windows XP and Fedora Core 9 are as below:
On Windows XP:
1) Go to www.zip.com, download zip.exe, double click on the downloaded exe, and click at least one "Next" button.
2) Go to www.im.com, download im.exe, double click on the downloaded exe, and click at least one "Next" button.
3) Go to www.firefox.com, download ff.exe, double click on the downloaded exe, and click at least one "Next" button.
On Fedora Core 9
1) Open terminal, type su root followed by root password, type yum -y install zip.
2) In the same terminal, type yum -y install im.
