A hardware malfunction
#12
What is the role of a supervisor mode in an operating system?
To restrict access to certain system resources
To manage user privileges
To execute privileged instructions and access restricted resources

#13
What is the difference between fragmentation and defragmentation?
There is no difference; both terms refer to the same concept
Fragmentation is the process of dividing files into smaller pieces, while defragmentation is the process of combining those pieces into contiguous blocks
Fragmentation refers to memory allocation, while defragmentation refers to disk space management
Fragmentation occurs in solid-state drives, while defragmentation occurs in hard disk drives
#14
What is the difference between a mutex and a semaphore?
There is no difference; both terms refer to the same synchronization mechanism
A mutex is a binary semaphore, while a semaphore can have multiple states
A mutex is used for process scheduling, while a semaphore is used for memory management
A mutex is used in real-time operating systems, while a semaphore is used in general-purpose operating systems
#15
What is the difference between multiprogramming and multitasking?
There is no difference; both terms refer to the same concept
Multiprogramming involves executing multiple programs concurrently on a single processor, while multitasking involves executing multiple tasks concurrently on a single computer
Multiprogramming involves executing a single program on multiple processors, while multitasking involves executing multiple programs on a single processor
Multiprogramming involves executing a single program, while multitasking involves executing multiple programs sequentially
#16
What is a kernel in an operating system?
The central part of the operating system that manages hardware resources
A type of programming language
A user interface component
A file system
#17
What is real-time operating system (RTOS)?
An operating system designed to guarantee a certain response time for specific computing tasks or processes
An operating system used exclusively in virtual environments
A type of operating system developed by real-time strategy game developers
An operating system primarily used for scientific computing
#18
What is a context switch in an operating system?
The process of switching between user and supervisor modes
The process of switching between different user accounts
The process of saving and restoring the state of a process or thread
The process of switching between different operating systems
#19
What is the purpose of the command-line interface (CLI) in an operating system?
To provide a graphical user interface
To manage network connections
To execute commands and interact with the operating system
To optimize memory usage
