What is a Linux kernel?
The Linux® kernel is the main component of a Linux operating system (OS) and is the core interface between a computer’s hardware and its processes. It communicates between the 2, managing resources as efficiently as possible.
The kernel is so named because—like a seed inside a hard shell—it exists within the OS and controls all the major functions of the hardware, whether it’s a phone, laptop, server, or any other kind of computer.
What are the 4 jobs the kernel does?
3 - Memory management: Keep track of how much memory is used to store what, and where
2 - Process management: Determine which processes can use the central processing unit (CPU), when, and for how long
3 - Device drivers: Act as mediator/interpreter between the hardware and processes
4 - System calls and security: Receive requests for service from the processes
