How to execute .asp or .aspx file from my computer?

When you want to execute your .asp/.aspx files on Windows IIS server you can get to know the name of the server or the local machine by right clicking on "My Computer" and then clicking "Properties" from the dialog box.

Under "Network Identification" or under the tab "Computer Name" there will be separate marking called "Full Computer name" followed by the name of the computer machine/server. For e.g. if the name is something like "myserver", then you can access the server side scripts by typing the following URL on the browser address bar

http://myserver/myprogram.aspx

Alternative way is to type http://localhost/myprogram.aspx or by typing
http://127.0.0.1/myprogram.aspx.

127.0.0.1 is the loopback address that causes requests to be sent to a web server on the local machine and 'localhost' is an alias for 127.0.0.1
