Operating System Concepts (by Abraham Silberschatz)

"Operating System Concepts" by Abraham Silberschatz explains how computer systems manage resources and run programs efficiently. The OS acts as an intermediary between hardware (like the CPU, memory, and storage) and users or applications, coordinating tasks such as running software, managing files, and ensuring security. It handles tasks like multitasking, resource allocation, and error detection to keep the system stable and responsive. Essentially, it enables computers to function smoothly and efficiently, allowing users to focus on their tasks without needing to understand complex hardware operations.
