In this section, we will take a look at Linux Syscalls.
-
A kernel is the major component of an operating system and is the core interface between a computer’s hardware and its processes.
-
The Kernel can be divided into two memory areas, user space and kernel space.
-
Applications running in user space get access to data on devices by making special requests to the kernel called system calls.
-
If we want to create an empty file called error.login the /tmp file system – it will make several system calls.
