Паффос! особенно в конце....

Everything else is ultimately simply details -- important details, but variants on that theme. index.php is the control, the menu program determins what the "present page" is, and bunches of occasions get fired along the way of building that page. Plugin modules can hook into those occasions and modify the work flow/provide added information/etc. That is also a part of the reason so many Drupal resources concentrate on making modules. Without modules, Drupal does maybe not really DO something other than say, 'Some one asked to get a page! Does it exist? No? OK, I will serve up a 404.'
