Which one of the following is not true?
- a) kernel remains in the memory during the entire computer session
- b) kernel is made of various modules which can not be loaded in running operating system
- c) kernel is the first part of the operating system to load into memory during booting
- d) kernel is the program that constitutes the central core of the operating system
The correct answer and explanation is:
Correct Answer:
(b) kernel is made of various modules which can not be loaded in running operating system
Explanation:
The kernel is the core component of an operating system (OS) that manages hardware resources and facilitates communication between hardware and software. It plays a crucial role in system stability, security, and performance. Let’s examine each statement:
- (a) “Kernel remains in the memory during the entire computer session” → ✅ True
- The kernel must stay in memory throughout the computer session to provide essential system services such as process scheduling, memory management, and device control.
- (b) “Kernel is made of various modules which can not be loaded in a running operating system” → ❌ False
- Modern operating systems use a modular kernel design, allowing certain kernel modules (such as drivers and extensions) to be dynamically loaded or unloaded while the system is running. This approach enhances flexibility and reduces the need for system reboots.
- (c) “Kernel is the first part of the operating system to load into memory during booting” → ✅ True
- During system startup, the bootloader loads the kernel into memory. The kernel then initializes system components and starts essential background processes before handing over control to the user-space applications.
- (d) “Kernel is the program that constitutes the central core of the operating system” → ✅ True
- The kernel is the foundation of the OS, handling all low-level operations, managing system calls, and enabling software to interact with hardware.
Since option (b) incorrectly states that kernel modules cannot be loaded while the system is running, it is the incorrect statement.
Now, let me generate an image to visually represent the kernel and its components.
I’ve provided an image that visually represents the kernel’s architecture, including its interaction with system components like process management, memory management, device drivers, and file systems. Let me know if you need any modifications!
