• Kernel

• User Interface

• Device Drivers

• File System

Which of the following is NOT a function of an operating system?

• Managing memory allocation

• Handling input and output devices

• Managing file systems

Which type of user interface allows users to enter text-based commands?

• Command Line Interface (CLI)

• Graphical User Interface (GUI)

• Touch-based Interface

• Natural Language Interface

Which type of operating system scheduling method ensures all processes get equal time to execute?

• Round Robin

• First Come First Served

• Shortest Job First

• Shortest Remaining Time

Which scheduling method prioritizes the job that will take the least time to complete?

• Shortest Job First

• Round Robin

• Multi-level Queue

Which of the following best describes a process in the ‘ready’ state?

• Waiting to be executed by the CPU

• Currently executing on the CPU

• Waiting for input/output operations

Which statement about virtual memory is true?

• It allows the system to use disk space as an extension of RAM.

• It is a type of high-speed cache memory.

• It is another term for main memory (RAM).

• It increases the physical size of RAM.

What is the primary difference between paging and segmentation?

• Paging divides memory into fixed-size blocks, segmentation uses variable-size blocks.

• Segmentation divides memory into fixed-size blocks, paging uses variable-size blocks.

• Paging uses virtual memory, while segmentation does not.

• Segmentation is used only in GUI-based operating systems.

What problem can occur when excessive paging slows down a system?

• Disk Thrashing

• Buffer Overflow

• Deadlock

• Memory Leak
