What are the three basic components of Linux?

• A. User Interface; Kernel; Disk Driver
• B. Bootloader; Kernel; User Space
• C. Kernel; System Library; System Utility
• D. Shell; Kernel; Network Daemon

Answer: (C)

Linux is commonly described as consisting of three parts: the kernel, the system libraries, and the system utilities. The kernel is the core piece that manages hardware, processes, memory, and device drivers, providing the essential services that all software relies on. The system libraries, such as the C library, offer standardized interfaces that applications use to perform common tasks without dealing with low-level details. The system utilities are the collection of programs in user space that perform everyday operations—file management, text processing, process control, and more—providing the tools you interact with on a running system. The shell is one of these utilities, but it’s just one program among many and not a separate fundamental component. Bootloaders belong to the boot process and aren’t part of the OS’s three main components, and disk drivers are implemented inside the kernel rather than as a standalone top-level component. Thus, kernel, system libraries, and system utilities best describe the standard Linux architecture.
