A software interface to the operating system that implements access
control by limiting the system commands that are available to a user is
called a(n):
A.
Physically constrained user interface
B.
Restricted shell
C.
Interrupt
D.
View
Explanation:
Answer Interrupt refers to a software or hardware interrupt to a processor
that causes the program to jump to another program to handle the
interrupt request. Before leaving the program that was being executed
at the time of the interrupt, the CPU must save the state of the computer
so that the original program can continue after the interrupt has
been serviced.
*A physically constrained user interface is one
in which a user’s operations are limited by the physical characteristics
of the interface device. An example would be a keypad with the
choices limited to the operations permitted by each key.
*View refers to database views, which restrict access to information contained
in a database through content-dependent access control.
