In computer science, the explicit responsibilities of an operating system (OS) include managing hardware resources (CPU, memory, storage, peripherals), providing process scheduling, memory allocation, file systems, device drivers and system call interfaces, and implementing isolation and protection among multiple user programs.

UnverifiedModern operating systems use the privilege-level mechanism provided by the CPU to divide the execution environment into user mode and kernel mode; user-mode programs run at a restricted privilege level and cannot directly access hardware or arbitrary memory; when they need services such as file read/write, network communication, or process management, they must trap into the kernel via a system call (syscall), and the kernel executes it on their behalf.79% similarUnverifiedThe traditional definition of an operating system is an abstraction layer that manages hardware resources, schedules processes, and provides file systems and device drivers.77% similarUnverifiedWhether a system can be called an OS hinges on whether it performs exclusive management and abstraction of some underlying resource.73% similarUnverifiedIn OS architecture, the kernel sits at the innermost layer, interacting directly with hardware and providing core mechanisms such as process management, memory management, interrupt handling and system calls, while leaving user interfaces, file management and network services to user-space programs.68% similarUnverified操作系统、计算机网络、数据库被视为「系统三件套」,构成工程师理解复杂软件系统的核心框架67% similar
