1.2.1b Paging, Virtual Memory

What is the primary function of memory management in a computer system?

• To increase the speed of the CPU

• To manage the allocation and deallocation of memory

• To enhance the graphics performance

• To control the input and output devices

Which of the following is a method of memory management that involves dividing memory into fixed-size units?

• Segmentation

• Paging

• Virtual Memory

• Defragmentation

In the context of memory management, what does segmentation refer to?

• Dividing memory into equal-sized pages

• Dividing memory into variable-sized segments

• Combining multiple programs into a single block

• Allocating memory based on user priority

What is virtual memory primarily used for in a computer system?

• To increase the physical size of RAM

• To allow a computer to compensate for shortages of physical memory

• To enhance the speed of the hard drive

• To store permanent data

In the video, what happens when Program C is closed?

• The memory is permanently lost

• The memory is released and becomes available for other programs

• The memory is transferred to the hard drive

• The memory is compressed

Why can't Program E fit into the available spaces in main memory, according to the video?

• The total free space is insufficient

• The free space is not contiguous

• The program is too large for any single block

• The memory is corrupted

What is one potential solution mentioned in the video for fitting Program E into memory?

• Increasing the size of RAM

• Moving the location of Program D in memory

• Compressing Program E

• Deleting other programs

What is the main challenge with moving programs in memory to create contiguous free space?

• It is time-consuming and complex

• It requires additional hardware

• It decreases the speed of the CPU

• It increases the risk of data loss

Which of the following best describes random access memory (RAM)?

• Permanent storage for data

• Temporary storage that is fast and volatile

• A type of external storage device

• A method of data encryption

What happens to the operating system when a computer first starts up?

• It is loaded into the hard drive

• It is loaded into random access memory (RAM)

• It is deleted from memory

• It is compressed to save space
