In fact, its name is really significant as El Capitan is the name of one of the most popular rock formations at Yosemite national park and it signifies that this version of Mac had more under the hood changes to the previous version that is Mac OS X Yosemite. This follows the similar naming convention Apple has followed for previous versions of Mac that contained updates to their predecessor like Lion / Mountain Lion and Leopard / Snow Leopard. In this version, Apple built upon the graphical changes brought upon in Mac OS X Yosemite and focused on the areas on user experience and performance.
