Understanding Memory and Processor Management

What is the primary purpose of paging in memory management?

• To divide the memory into variable-sized segments

• To divide the memory into fixed-sized blocks

• To increase the speed of the processor

• To enhance the security of the system

Which of the following best describes segmentation in memory management?

• Dividing memory into fixed-sized pages

• Dividing memory into variable-sized segments

• Allocating memory based on process priority

• Using a single contiguous block of memory

What is the main difference between paging and segmentation?

• Paging uses variable-sized blocks, while segmentation uses fixed-sized blocks

• Paging uses fixed-sized blocks, while segmentation uses variable-sized blocks

• Both use fixed-sized blocks

• Both use variable-sized blocks

Which of the following is a method for replacing pages in virtual memory?

• First Come First Served

• Least Recently Used

• Shortest Job First

• Round Robin

What is disk thrashing?

• A condition where the CPU is over-utilized

• A condition where the system spends most of its time swapping pages in and out of memory

• A method of scheduling processes

• A technique for optimizing disk usage

In processor management, what does multitasking allow?

• Running multiple processes simultaneously

• Running a single process at a time

• Allocating memory to a single process

• Using a single CPU core for all tasks

Which of the following is NOT a process state?

• Running

• Ready

• Blocked

• Terminated

Which scheduling routine is based on the time quantum?

• Shortest Job First

• Round Robin

• First Come First Served

• Shortest Remaining Time First

How does an OS kernel act as an interrupt handler?

• By executing processes in a sequential manner

• By managing memory allocation

• By responding to hardware and software interrupts

• By scheduling tasks based on priority

What is a composite data type?

• A data type that consists of a single value

• A data type that consists of multiple values or elements

• A data type used only for numerical values

• A data type used only for text values
