$area1, $area2...etc

Hi. Apologies if this got posted under a different title. Can someone please tell me what $area1, $area2, $area3 are used for? I know they are variables used for displaying content on the page but am I correct in sayign that $area1 is solely used for displaying content from content.php and the others can be used for populating with widgets etc? Is that why I have seen area4 and 5 mentioned before as well? Does that also mean that 1 widget populates 1 area or can more than 1 widget say populate $area2? Cheers
