Types of programs include system programs, application programs, utility programs, etc. Types of function include modulus function, linear function, quadratic function, exponential function, etc. Program consists of compiled code that run directly from computers operating system. Functions can be used over and over again once it is defined. It is larger in size and does not require scripting engine to run. Functions are smaller in size as compared to programs.
