Engine markings

I've searched the forum but no luck finding the answer to my question...

What is the significance of the "markings" left by mechanics on various components in the engine compartment. (e.g. a yellow marking on the upper radiator hose where it meets the housing) There are various other marks of various colors elsewhere, usually on a fastener or at a connecting junction.

What do these mean and do the different colors signify anything?

Many thanks in advance!
