About 2 months ago I rooted and installed the 1-click lag fix from the market. I also downloaded rom manger. Just now I opened rom manger and used it to install clockwork mod. What is a rom? If I install a rom am I modifying the kernel? What is the difference between installing a new rom, and installing a kernal. We flash both of them? If so I assume that I need to undo the lag fix and get my regular file system back - is this an accurate assumption? Any help would be awesome and much appreciated. Side note: I have tried to search about this information, but nobody has a single detailed explanation of what each these mean. I have a hard time finding something that explains the differences between a rom, and a kernel (if there is any). Back when I was trying to learn what rooting was I couldn't even figure out what that meant for the longest time. If I can figure this out I will try to piece together a guide for the noobs like me - something that isn't 200+ pages, but still has the basic info so you at least know what to search for.
