Systems Programming Exam Solutions
Course Introduction
Systems Programming focuses on the development of software that provides services to the computer hardware and acts as a foundation for application software. This course covers essential concepts such as operating systems, compilers, assemblers, loaders, linkage editors, and system utilities. Students learn about low-level programming using languages like C and assembly, concepts of memory management, process control, file systems, and device management. Emphasis is placed on writing efficient, robust system software and understanding the interface between hardware and software. The course also explores debugging tools, performance analysis, and security considerations inherent in software that interacts closely with hardware.
