First of all, "IsPostBack" is an property in ASP.Net Page andit returns truewhen the page postedback by server otherwise it will return true.
Say for example, you have a button in an aspx page and when yourequest the page in the url, the "ispostback" propertyset as "false"when you click on the buttonthe page will submit ( postedback)to the web server (IIS) and the page is processed by the IIS and sent it to browser. At this time it will set the "ispostback" as true.

IsPostBack property tells that the page is rendered first time or it is posted back by some server control. If it returns true, it means it is posted back by some control like button click.
