What is OS concepts?

Operating System (OS) concepts encompass the fundamental principles and mechanisms that govern how a computer system manages hardware and software resources. Key concepts include process management (scheduling, synchronization, communication), memory management (allocation, virtual memory), file system management (organization, access control), input/output (I/O) management (device drivers, interrupt handling), and security (authentication, authorization). OS concepts are crucial for understanding how software interacts with hardware, how multiple applications can run concurrently, and how system resources are protected. They are used in designing, developing, and maintaining operating systems and other system-level software.
