B)RTOS
C)GUI
D)DOS

Question

Quizplus · Accepted Answer

MILS (Multiple Independent Levels of Security) is an architecture that allows for multiple levels of classification to run on the same CPU without leakage between levels. MILS is commonly used in embedded systems that require high levels of security, such as military and aerospace applications. RTOS (Real-Time Operating System) is a type of operating system that is designed to handle time-sensitive tasks and is often used in embedded systems, but it does not guarantee the same level of security as MILS. GUI (Graphical User Interface) is a type of interface that allows users to interact with a computer using visual elements, such as icons and menus. DOS (Disk Operating System) is an old operating system that is no longer commonly used.
