Machine.config:
– It gets created at the time of Visual Studio installation.

– There can be only one machine.config file exists in a server.

– This is only for machine level configuration like requestLimit, memoryLimit, ClientConnectedCheck etc.

Machine.config file located in below location:
\WINNT\Microsoft.NET\Framework\[Framework Version]\CONFIG\machine.config

Example:
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config

Web.config:
– This got created when you create a web application project.

– This contains information for the application level. And this file inherits setting from the Machine.config file.

– we can store information like Database connection string, session details etc in web.config file.

Some points to remember:
– The settings made in the Web.config file are applied to that particular web application only whereas the settings of Machine.config file are applied to the whole asp.net application.

– web.config file inherits settings from machine.config file.
