GATE - 1998 [Operating System]

Question:

A linker reads four modules whose lengths are 200, 800, 600, and 500 words, respectively. If they are loaded in that order, what are the relocation constants?

A

0, 200, 500, 600

B

0, 200, 1000, 1600

C

200, 500, 600, 800

D

200, 700, 1300, 2100

   

Solution:

Option (B) is Correct.

First module loaded starting at address 0. Size is 200. Hence it will occupy first 200 address, last address being 199.


Now 2nd will start loading at 200, since size is 800, so last address is 999.


Now 3rd module will start loading at 1000, since size is 600. So last address is 1599.


Now 4th module will start loading at 1600 and go till 2099.

 

Thank You
