how do i read webalizer stats?

this may seem like an easy question but i'm confused as to how to read webalizer stats. here are the daily stats for yesterday:

hits: 2703
files: 2439
pages: 69
visits: 20
sites: 48
kbytes: 18658

i'm confused as to what the difference between hits and files is. and visits? could someone clarify? thanks!
