True or False 8. The Zero flag is clear when the result of an arithmetic operation is zero. 9. Registers in the floating-point unit are 80 bits long. 10. Microprograms are interpreted and executed by machine instructions. 11. In Real-address mode, only one program can run at a time. 12. In Virtual-8086 mode, only a single virtual machine can run at one time. 13. In the multi-segment model (Protected mode), each program is given its own local descriptor table. 14. Segment limit and base address are both fields within a segment descriptor. 15. In Protected mode, the total memory used by all running programs can never be larger than the computer's physical memory
