SLR4: Paging, segmentation & VM

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

• To increase the speed of the CPU

• To efficiently allocate and manage memory resources

• To enhance the graphics performance

• To improve network connectivity

In the context of memory management, what is paging?

• Dividing memory into variable-sized sections

• Dividing memory into fixed-sized sections

• Storing data on the hard disk

• A method to increase CPU speed

What is a potential disadvantage of paging?

• It requires more hard disk space

• It can separate related instructions, leading to inefficiency

• It increases the speed of memory access

• It reduces the amount of available RAM

How does segmentation differ from paging?

• Segmentation uses fixed-sized sections, while paging uses variable-sized sections

• Segmentation uses logical divisions, while paging uses physical divisions

• Segmentation is faster than paging

• Segmentation is a type of virtual memory

What happens when a program is too large to fit into the available memory spaces?

• The program is terminated

• The program is split and stored using segmentation

• The program is stored entirely on the hard disk

• The program is compressed to fit

What is virtual memory?

• A type of RAM that is faster than regular RAM

• A method to increase the physical size of RAM

• A technique to use hard disk space as an extension of RAM

• A method to store data in the cloud

Why is virtual memory used in modern computers?

• To increase the speed of the CPU

• To allow more programs to run simultaneously than the physical RAM can hold

• To improve graphics performance

• To enhance network connectivity

What is the role of the bootstrap program in memory management?

• To manage network connections

• To load the operating system from the disk into RAM

• To increase the speed of the CPU

• To enhance graphics performance

What happens when RAM is full and a new program needs to be loaded?

• The computer shuts down

• The new program is not loaded

• Some instructions are moved to virtual memory

• The CPU speed is reduced

Which of the following is a similarity between paging and segmentation?

• Both divide memory into fixed-sized sections

• Both divide memory into logical divisions

• Both are methods to manage memory efficiently

• Both increase the physical size of RAM
