System call. A high-level overview of the Linux kernel's system call interface, which handles communication between its various components and the userspace.

Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive interface available with punched cards ...
