Memory Management Quiz

What is the primary focus of the video?

• File systems

• Network protocols

• CPU scheduling

• Memory management

Which of the following is NOT mentioned as a memory management strategy in the video?

• Cache memory

• Paging

• Segmentation

• Virtual memory

What happens when program C is closed?

• The memory is released

• The memory is fragmented

• The program is swapped out

• The program is moved to disk

Why is moving a program in memory not desirable in practice?

• It is not supported by modern operating systems

• It requires additional hardware

• It is too expensive

• It takes a lot of time

How does paging divide memory?

• Into fixed-size pages

• Into variable-size segments

• Into logical divisions

• Into arbitrary blocks

What is a potential issue with paging?

• It is slower than segmentation

• It is not compatible with modern CPUs

• It requires more memory

• It can separate instructions inside a looping condition

How does segmentation divide memory?

• Into fixed-size pages

• Into arbitrary blocks

• Into equal parts

• Based on logical divisions

What is virtual memory?

• A method to increase CPU speed

• A type of physical memory

• A way to store data permanently

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

What happens when a computer runs out of RAM?

• The operating system crashes

• Instructions not being used are transferred to the hard disk

• The computer shuts down

• The CPU stops working

Why does a computer slow down when using virtual memory?

• Because the programs are too large

• Because the operating system is outdated

• Because the CPU is overloaded

• Because accessing the hard disk is slower than accessing RAM
