Question

HLA assembly program

Question 1:

The bits stored in the EFLAGS register are extremely perishable and can be used to force a conditional jump only when the desired conditional jump instruction directly follows the CMP( ... ) instruction.

True/False

Question 2:

Because of the way the CPU registers overlap, when changing the bits in a certain CPU register, an HLA programmer may also be changing the bits in one or two other CPU registers.

True/False

Question 3: Given the way AND( ... ) works, the most likely outcome is a true result (that is, the value 1), not a false result (that is, the value 0).

True/False

Question 4: When programmers work with assembly language instructions, the source and destination registers or operands of a MOV instruction must have matching sizes.

True/False

Question 5: A single hexadecimal digit can represent one of eight different possible values.

True/False

Question 6: In a binary number represented by 8 bits, the "zeroth bit" of this number will also referred to as the "high-order bit".

True/False

Question 7: In a binary number represented by 16 bits, the "zeroth bit" of this number will also referred to as the "low-order bit".

True/False

Question 8: Given the way OR( ... ) works, the most likely outcome is a true result (that is, the value 1), not a false result (that is, the value 0).

True/False

Question 9: Assembly language programs are processor-specific and not portable from one type of CPU to another.

True/False

Question 10: When the bits of register AH are changed by an HLA programmer, no other register will find its bits changed as a result.

True/False

Explanation / Answer

Q1

This is true

Q2

This is false as we can't change the content of two registers at the same time.

Q3

This is false as according to the truth table only 1 out of 4 case have the answer as true

Q4

This is true as both must be of same size

Q5

This is false as hex value represent 16 different value

Q6

This is false

Q7

True

Q8

This is true as from truth table of OR, only when both numbers are 0 then the instruction is false

Q9

This is true

Q10

This is also true
