Few more questions

1. I saw there two product one was Express Edition & another Enterprise/Standard Edition. What is the difference between them?

2. However I decided to use Enterprise/Standard Edition. But in its download page http://www.oracle.com/technology/software/products/database/oracle10g/htdocs/10201winx64soft.html I saw few more downloads like Companion CD Release 2, Client Release 2, Clusterware Release 2 what are these downloads for? Which components I need to have

Express edition is free to use .. For Enterprise or Standard edition, you'll need a licence ..
The g in 10g stands for Grid computing .. Clusterware is a grid computing platform ..
Express edition will be more than enough for you to learn Oracle database ..
