Answer 1

1. In real-address mode, convert the following segment offset address to a linear address: 0950:0100

Add the Hex address which is...

09500 + 100 = 09600

Therefor the linear address is 09600(hex).

2. In real-address mode, convert the following segment offset address to a linear address: 0CD1:02E0

0CD10 + 2E0 = CFF0(hex)

3. What is the duration of a single clock cycle (in nanoseconds) in a 3.4 GHz

1Giga=10⁹ .

1/3.4*10^9= 0.294 ns

4. A hard disk rotates at 4200 RPM (rotations per minute). What is the time of one rotation in milliseconds?

Rotation in one second = 4e200/60 = 70 (rotations per second)

1milliseond = 10^-3 seconds

Rotation time in 1 milliseconds = 1000/70 = 14.285

5. Which Intel processor was the first member of the IA-32 family?

386

6. Which Intel processor first introduced super scalar execution?

x86

7. Name all 32-bit general-purpose registers.

EAX, ESP, ESI, EBP, EDX, EBX, EDI, ECX

8. Name all six CPU status flags in the Intel processor.

Sign flag, Zero flag, Auxiliary carry flag, Parity flag, Overflow flag, Carry flag

9. Which flag is set when an arithmetic or logical instruction produces a
negative result?

Sign flag is set when an arithmetic or logical instruction produces a
negative result.

10. What is the range of addressable memory in protected mode?

uptill 4 GB.
