so if there is a command line and there is a text in it and waiting for an 'enter' to be pressed in which buffer does it stay?,in a program buffer or a keyboard buffer?

It depends on the platform, but for example on a .NET console app running on Windows, if you call Console.ReadLine() while the app has focus it is going to receive the keyboard input and store it in an application level buffer. The only time it would stay at a lower level buffer is if the system is too busy to process the input in time. At this level 'buffering' is really just a semantic concept; the system is basically at rest, the input has been processed, transformed into a UTF-8 string and stored in memory waiting to be returned to your program when the enter key is detected.
