Which component of Linux architecture functions closest to the hardware?A. KernelB. Graphics ServerC. ApplicationsD. OS Shell

Step 1: Identify Components of Linux Architecture

To answer the question, we need to understand the functions of each component in the Linux architecture:

1. Kernel: The core component of the Linux operating system that interacts directly with the hardware.
2. Graphics Server: Manages graphical output and input, but sits on top of the kernel.
3. Applications: User-facing programs that run on the operating system.
4. OS Shell: Provides a user interface to interact with the operating system but does not communicate with hardware directly.

Step 2: Analyze the Functionality

• The Kernel is responsible for managing system resources, facilitating communication between hardware and software, and providing essential services for all other parts of the system. Thus, it functions closest to the hardware.
• The Graphics Server, Applications, and OS Shell are built on top of the kernel and do not interact with the hardware directly.

Step 3: Conclusion

Based on the analysis, the component of Linux architecture that functions closest to the hardware is the Kernel.

Final Answer

A. Kernel
