Prueba AMV

Mark the wrong answer.In current systems, the addresses assigned to symbols in program files…

• are logical addresses
• are a subset of the logical address space of the processor
• should be different for each program to implement protection
• are the addresses referenced by the CPU

Mark the wrong asnwer. The MMU…

• receives all the addresses referenced by all user processes
• implements translation and protection at loading time
• Implements translation and protection at execution time
• It is configured by the OS when a process reaches the CPU

A context switch

• involves configure the MMU with the new address space
• it is not related with the memory management
• always deallocates the physical memory of the leaving proc.
• None of the above

The exec system call

• involves allocate physical memory
• involves deallocate physical memory
• causes the loading of a program
• All of the above

If a system implements loading of demand….

• it can speedup the loading of programs
• It is possible to increase the multiprogramming grade
• size(logical_addess_space) >= size(physical_address_space)
• all of the above
