What is an MD5 and what does it do?

[FCO2011]

Hey all, when I read through some rooting/ROM threads on this forum and others, I always see the word "MD5" pop up, and that people need to "Check the MD5 so it matches".

Well...what is an MD5? And why do I need to check it if it "matches"? What role does it play in rooting/flashing ROMS?

Thanks
