Page_Load is an event handler. It basically tells what should happen if a page is loaded. sender is what caused this event and e contains information about the event. For instance, if you drop a ball from certain height,

event: you dropping the ball
sender: you
e: information about the event. Something like from which height you dropped the ball.

Basicly the Page_Load function is an event handler. The sender is the event raising object, and the e variable is the event arguments. Take a look into the following subjects:
