What is the primary purpose of the Linux kernel?

The primary purpose of the Linux kernel is to serve as the core component of the Linux operating system. The kernel is responsible for managing system resources such as CPU, memory, and hardware devices, acting as an intermediary between the hardware and software applications. It handles process control, file management, and system calls, ensuring that various components of the system can communicate effectively.

In contrast, managing user account information, compiling software applications, or displaying system logs are tasks that are handled by other aspects of the operating system or specific applications rather than the kernel itself. User account management is typically facilitated by user space utilities, while compilation and log display are carried out by various software tools and commands, which operate on top of the kernel.
