Unformatted text preview: 24. If, in a single, contiguous memory-management system, the program is loaded at address 30215 , compute the physical addresses (in decimal) that correspond to the following logical addresses: a. 9223 b. 2302 c. 7044 25. If, in a fixed-partition memory-management system, the current value of the base register is 42993 and the current value of the bounds register is 2031, compute the physical addresses that correspond to the following logical addresses: a. 104 b. 1755 c. 3041 26. If, in a dynamic-partition memory management system, the current value of the base register is 42993 and the current value of the bounds register is 2031, compute the physical addresses that correspond to the following logical addresses: a. 104 b. 1755 c. 3041...
