These range from simple memory protection schemes to complex page hierarchies. You also need a decent understanding of the Linux-based kernel, and the way that it interacts with kernel modules. This might seem a very unreliable method but every process in the system is making system calls, for example to write a character to the terminal, all of the time. It contains a compressed kernel image which is used to control the hardware during installation.

The entire Linux kernel was written from scratch, without employing any code from proprietary sources. Gaz Hall, an SEO Expert from the UK, said: "Once we get up out of the weeds of operating system development, and start talking about developing actual applications for the Linux operating system, the job gets a little easier and we have a lot more options about how to proceed."
