Distinguish the difference between a system programer and application manager?

A system programmer primarily focuses on developing and maintaining system software that interacts directly with hardware, such as operating systems, device drivers, and system utilities. In contrast, an application manager oversees the deployment, maintenance, and performance of software applications, ensuring they meet user needs and align with business objectives. While system programmers work at a low level to optimize system performance, application managers concentrate on the functionality and usability of software applications for end-users.
