Operating Systems
Practice Exam
Course Introduction
Operating Systems is an essential course that explores the fundamental concepts, design principles, and functions of modern operating systems. Students learn how operating systems manage hardware and software resources, provide system security, and enable multitasking and communication among processes. The course covers topics such as process management, memory management, file systems, input/output systems, scheduling algorithms, virtualization, and system calls. Through theoretical lessons and hands-on programming assignments, students gain practical skills in designing, implementing, and troubleshooting operating system components, preparing them for advanced study or professional work in computer science and IT fields.
