A computer program is a set of instructions that tell a computer what to do. Are instructions specific orders of steps to do something. Like a recipe to bake a cake which is an example of where instructions may be used. Am I right yes or no? If I am not right please tell me why?
It all boils down to a series of instructions. That is all a computer can execute. All that programming languages are is a convenient way to give computers instructions. You have to be very precise because the cpu follows those instructions to a fault.
