What Is SAP (System Application Programming)?

SAP (System Application Programming) – A type of programming that is to develop applications that interact with the system software (operating system), or computer hardware. The main difference between system programming compared to application programming is that, application software is designed for end users (eg, word processors, graphic editors), while the resulting system programming are programs that cater to the hardware or operating system (such as defragmenting the disk) which causes a significant dependence of this type of software from hardware. It should be noted that the “normal” applications can be used in the work code fragments characteristic of system software, and vice versa; so there is no clear boundary between application and system programming. Since different operating systems differ both interior architecture and ways to interact with the hardware and software, the principles of system software for different operating systems are different. Therefore, the development of applications that carry out the same actions on different operating systems may differ.
