Translation:The computer has no access to the keyboard.
What does this mean, exactly? That the keyboard isn't connected to the computer? Or (more humorously) that you can't blame the computer for your keyboarding mistakes? Or something else?
Meaning that the computer doesn't permit you to use the keyboard? Or something else?
The computer isn't permitted to use it. Maybe because the cord is broken or because the keyboard is protected with a password.
Or it could be a headless system, with no screen or keyboard. So you would just ssh into it from another computer.
