A computer translates code into something it can follow instructions by simply running the program that was created. it automatically translates the code into binary strings and then processes the numbers created. The code essentially translates all of the important values and functions into binary code. Then the code tells the computer what to do with that information. This  comes out to multiplying, dividing, adding , or subtracting in the processor. Of course, the processor does this billions of times a second. There are many languages that convert this into binary, such as the 'universal' language in C++, languages like java and python, and others like it.
