I'm stuck on the 1st and 4th question.

1. (2 pts) If you desired to set the direction flag, carry flag and zero flag, what hexadecimal number would you "OR" it with? 2. (2 pts) If you wanted to clear the carry flag, sign flag, and overflow flag, what hexadecimal number would you "AND" it with? 3. (2 pts) If esp = 0x12ff0 and you pushed 3 parameters onto the stack, what is the new value of esp? 4. (2 pts) Earlier in the code you pushed 4 registers to the stack and esp = Ox129A0, now you restore them, what is the new value of esp? 5. (2 pts) Virtual memory is a useful design to help with which of the following? a. When the amount of physical memory is less than the address space of the processor. b. When global variables are assigned a new value during program execution. c. When writing data to / from a hard disk. d. When the amount of physical memory is greater than the address space of the processor. e. Multiple processes can be run at the same virtual address without concern for overwriting each other's memory
