Assume a base register is set to 2000 (hex) and the bound register is set to 3FFF (hex), given a logical memory address of 02AB (hex) what is its physical address in hexadecimal?
A. 1FFFF
B. 1DF4
C. 22AB
D. 3D54
Homework Answers
Correct option - C
physical address= logical address + base register
=02AB + 2000
= 683 + 8192
= 8875(22AB)

You want to access the 818,768th byte of physical memory. Is it possible to reach this value from some segment using the hexadecimal offset 2A30? If so, what value would you load into the segment register? Write the full logical address in segment:offset format needed to access this byte in physical memory. Use hexadecimal
