FIGURE 1Discussion on Question 5 of Lab 6:The limitation on the amount of memory you can install in a 32-bit operating system is 4 GB, whichcomes from the fact that 232= 4 G (i.e. 4×1024×1024×1024)?What about the memory limitations forthe various 64-bit editions of Windows 10, say, Windows 10 Education, Windows 10 Professional, etc.?Why do you think they are NOT 264?Points to ponder upon1.Addressing SpaceIf we are given 2 bits for addressing, we can see up to 4 bytes of memory, since 22is 4If we are given 4 bits for addressing, we can see up to 16 bytes of memory since 24is 16If we are given 10 bits for addressing, we can have 1,024 bytes of addressing space as 210is 1024If we are given 20 bits for addressing, we can have 1024 × 1024 bytes of addressing space, whichis 1MBIf we are given 30 bits for addressing, we can have 1024 × 1024 × 1024 bytes of memory, whichis 1GBThus 40-bit addressing space corresponds to 1 TB of maximum memory support; 50-bit, 1 PB(petabytes); 60-bit, 1 EB (exabytes)
