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 kernel is the core component of an operating system. It’s the essential program that manages the computer’s hardware and software resources. Think of it as the central nervous system of a computer.
Key characteristics of the kernel:
- Residency: It remains in the computer’s memory throughout the entire operating system session. This constant presence allows it to respond to system requests and manage resources efficiently.
- Loading: The kernel is typically the first part of the operating system loaded into memory during the boot process. It initializes the system and prepares it for other software.
- Modularity: Modern kernels often consist of multiple modules. While some parts of the kernel are always present, others can be loaded or unloaded dynamically as needed. This flexibility enhances the kernel’s adaptability and allows for updates without requiring a full system restart.
The incorrect statement: “Kernel is made of various modules which can not be loaded in running operating system” is false because, as explained above, many modern kernels support dynamic loading and unloading of modules. This capability is crucial for system updates and adding or removing functionalities on-the-fly.
In essence, the kernel is a complex piece of software that acts as a bridge between the hardware and applications, ensuring efficient resource allocation, process management, and overall system stability.
