until I know about system call context , system calls are using for calling functions that kernel provides, from our user space programs(c,python,etc programs), that refer the control of execution from user-space program to kernel because executing desire function such as changing directory belongs to kernel territory,
and most of system calls can be called from shell commands, exactly as chdir,
I hope this helps
