How can you check the version of kernel you are currently running and upgrade the kernel?

Answer:
These are separate and unrelated tasks. To check the version of the running kernel in Linux, use the command uname -r. To upgrade the kernel, either use your distro's package manager (if any) to update the system, or download and compile the Linux kernel source.
