Difference between 301 and 302 redirects?

[Robertkuok]

301 directories is permanent redirection. like example fugenx(dot)com is there we need fix this domain in to many ways by using 301 directories.
1. <!-- m --><a class="postlink" href="http://fugenx(dot">http://fugenx(dot</a><!-- m -->)com
2. fugenx(dot)com
3. <!-- m --><a class="postlink" href="http://www.fugenx(dot">http://www.fugenx(dot</a><!-- m -->)com
4. <!-- m --><a class="postlink" href="http://www.fugenx(dot">http://www.fugenx(dot</a><!-- m -->)com
5. <!-- m --><a class="postlink" href="http://www.fugenx(dot">http://www.fugenx(dot</a><!-- m -->)com/index

by redirecting these all domain in to one particular domain permanently this process is called as 301 direction.

302 direction also similar to 301 direction but it is temporary redirection.
