Operating Systems and System Programming Test Bank
Course Introduction
This course provides an in-depth exploration of operating systems and system programming concepts, focusing on the design, implementation, and management of modern computer systems. Students will learn about process management, memory management, file systems, input/output systems, and security mechanisms. The course also covers system-level programming in languages such as C, including inter-process communication, synchronization, and system calls. Through hands-on projects and laboratory exercises, students gain practical experience in developing and debugging low-level software, understanding how software interacts with hardware, and managing resources efficiently in multi-user and networked environments.
