The OS kernel is asked to run a program via the execve system call, which signals the kernel to load the program from an executable file, typically in ELF format on Linux. The kernel then sets up the stack, loads code and data into memory, and prepares to jump to the entry point of the program, which is typically a function called _start that initializes the language's runtime before calling ...
