  Command (computing) Summary
Commands are the instructions, also called directives, which are conveyed to a computer or an associated device.
In computing, a command is a directive to a computer program acting as an interpreter of some kind, in order to perform a specific task.
Most commonly a command is a directive to some kind of command line interface, such as a shell.

 Noncommand User Interfaces
Most computer history textbooks use fundamental changes in the underlying hardware technology as the defining feature of computer generations, but as shown in Table 1, there are actually several other interesting dimensions of computing that have followed a set of generations roughly parallel with hardware developments, as the scope of user interfaces has broadened [47].
With this syntax, the computer has knowledge of the operand at the time where the user tries to select the operator, and it can therefore help the user select a function that is appropriate for that object by only showing valid commands in menus and such.
