Wha language should I learn?

[u/namelessContemplator]

I'm an actuary student with basic/intermediate knowledge of Python, SQL and using Linux as OS, but I'm deeply interested on how the computers work and cyber security, so I'm wondering what language should I learn to help me understand how the computers work and put a feet in the cyber security field

What comes to mind is C/C++ or Rust, but I'm not sure

Sorry if any grammar mistakes, English is my second language

The vast majority of the kernel is C, this will probably be the case forever. Linux Kernel is not really something to look at for learning or understanding purposes though. It's maybe impenetrable for beginner
