In processor management, what does the "blocked" state of a process indicate?

• The process is currently executing

• The process is ready to execute

• The process is waiting for an event to occur

• The process has completed execution

What is the main difference between paging and segmentation in memory management?

• Paging divides memory into variable-sized units, while segmentation divides it into fixed-sized units

• Paging divides memory into fixed-sized units, while segmentation divides it into variable-sized units

• Both paging and segmentation divide memory into fixed-sized units

• Both paging and segmentation divide memory into variable-sized units

What is virtual memory primarily used for in an operating system?
