"Envoriment variable PATH" on Ubuntu

Question

When we install a program using apt-get, after installed it's available in terminal, normally, when we just call "your name" independent of context directory we are.

On Windows, when we add a path to envoriment variables in variable PATH all programs or files in this path are available in terminal (prompt command) to be called.

In Ubuntu, how does it when we want to make a program callable but it is a standalone file installed without apt-get or aptitude?
