Global.asax is basically ASP.NET Application file. It’s a place to write code for Application-level events such as Application start, Application end, Session start and end, Application error etc. raised by ASP.NET or by HTTP Modules.
There is a good list of events that are fired but following are few of the important events in Global.asax:

Application_Init occurs in case of application initialization for the very first time.
Application_Start fires on application start.
Session_Start fires when a new user session starts
Application_Error occurs in case of an unhandled exception generated from application.
Session_End fires when user session ends.
Application_End fires when application ends or time out.
