Question 1

What is for jump

Answer 1

We can jump anywhere in physical memory

Question 2

What is bubble sort

Answer 2

Target any 2 elements of array, compare them and sort. Then pick another number,compare them and if require then swap them and so on, until whole array get sorted.

Question 3

How to define an array in assembly

Answer 3

dw, 60, 55, 12, 16

Question 4

What is keyword for swap

Answer 4

swap

Question 5

What is first executable instruction

Answer 5

offset 0100

Question 6

What is JMP

Answer 6

It is the unconditional jump that executes regardless of the state of all flags.

Question 7

What is relative addressing

Answer 7

It does not tell the exact address rather it tells how much forward or backward to go from the current position

Question 8

What are types of jumps

Answer 8

The three types of jump, near, short, and far

Question 9

What is Near Jump

Answer 9

When the relative address stored with the instruction is in 16 bits, the jump is called near jump

Question 10

What is short jump

Answer 10

If the offset is stored in a single byte, the jump is called a short jump.

Question 11

Is it true unconditional jumps can be short, far and near and conditional jumps can only be short.

Answer 11

Yes

Question 12

What is Far jump

Answer 12

Far jump is not position relative but is absolute. Both segment and offset must be given to a far jump. The other 2 jumps were used to jump within a segment. Sometimes we may need to go from one code segment to another, and near and short jumps cannot take us there. Then we use far jump. Far jump is intra segment.
