Expalin (Object sender,EventArgs e)

Object is the control object that is firing the event.

EventArgs will contain necessary event data from which this event has been called.

For example
protected Edit (object Sender, GridViewEditEventArgs e)

Here sender will be the GridView
e will contain the necessary property from which you can get to know that from which row the edit button has been clicked.

Thank you.

It is just a signature which is defined in the delegate

System.EventHandler

It is general to many events.

You can define a new delegate for you if you want :
public delegate void CustomEventHandler(object sender, CustomEventArgs e);

We can do the event related functionalities according to the object fired the even thrugh these.

Best example I can provide is rowdatabound. below is an example.

Protected Sub grdvw1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) 





   If e.Row.RowState = DataControlRowState.Edit Then 

      e.Row.Cells(2).BackColor = Color.LightSalmon





End If 

Mark this as answer, if it is.....
