Today my paper :) mcqs mostly from past paper
Subjective.....
Q : Which BOIS interrupt provides services for serial port? Mark 2
Q : what the 5:6:5 format means? Mark 2
Q : IVT is located at which location in the memory? Mark 2
Q : TF has every special relation with interrupt and debugger. Briefly describe this relation? Mark 2
Q : How to create or Truncate File using INT 21 Service?INT 21 - CREATE OR TRUNCATE FILE? Mark 3
Q : In C and Pascal calling convention, which registers are used as scratch when we call a function? Mark 3
Q : Consider the following interrupt that save the current content of AX register into PCB MOV [pb+bx+0], Ax
now write down intruction for saving the current contents of CX,DX,SI,DI,BP,and ES register into PCB in same order? Mark 3
Q : in order terminate a program, we can use either services 4C or services 31 of INT, how these services are different in their working? Mark 3
Q : In BIOS video services, which specific services in text mode are invoked by the following values of AH register?
AH=1
AH=2
AH=3
AH=4
AH=5
AH=6
AH=7
AH=8
AH=9 ???? Mark 5
Q : write an assembly program attributes for loading program using INT21? Mark 5
Q: keeping the VISA services into view, describe the purpose of following two instruction.
MOV AX, 0*4f02
MOV bx, 0*4117 ??? Mark 5
Q : how many types of interrupt are used for writing debugger?? Also alaborate the functionality of these interrupt with proper example?? Mark 5
