Possible to use Arduino without board?

I am a noob and it might be a stupid question, but is it possible to run code inside the Arduino environment without the board attached to the computer?

The Arduino IDE does not include a simulator.
So you can write the code, and compile it to check it for errors, without an Arduino board connected.

But to actually run the code, you need an Arduino board.

Once you have uploaded your sketch you can place the uP in another circuit ( EMBED ); as soon as you power the circuit the code starts running.

First you write a sketch.while uploading the sketch of course you nedd computer but while running the program you just need to provide the power supply which can be external i.e apart from computer too.and everytime you power the arduino it operates the code automatically
