Techopedia Explains Port (an Application)

To port an application means to allow an application program to run on a different OS. Machine dependent sections of the program must be rewritten as these are sections of the program that will execute only on a certain type of computer. Programs designed to run on a variety of types of computers, using different OSs, are said to be machine-independent.

Programs easily ported are said to be portable; or stated differently, when the manpower cost of porting to a new OS is less than that required to rewrite the entire program (i.e. from scratch), the program is described as portable.
