What is kernel version and updates in Linux?

In Linux, the kernel version refers to the specific release of the Linux kernel that the operating system is currently using. The kernel acts as the core part of the operating system, managing hardware resources and enabling communication between software and hardware components. Each kernel release is identified by a version number that typically follows a format of "major.minor.patch" (for example, 5.15.7).

Kernel updates in Linux are critical for ensuring system stability, security, and performance. These updates may include bug fixes, security patches, and new features. Keeping your kernel updated is essential for maintaining optimal system functionality and protecting your system from vulnerabilities.

To check your current kernel version, you can use the following command in your terminal:

uname -r
