(#M40154339) AMCAT QUESTION Computer science Keep an EYE

Any program residing in the memory contains a set of instructions that need to be executed by the
computer in a sequential manner. This cycle for every instruction is known as the instruction cycle. The cycle
consists of the following steps which may or may not be the proper sequence of the execution.
1. Fetch the operand from the memory
2. Execution
3. Fetch instruction
4. Decode the instruction
5. Result
In which of the following steps, is the Program Counter (PC) loaded with the address of the next
instruction?
o Execution
o Fetch instruction
o Decode the instruction
o Result

Consider the following reference string -
1, 2, 3,4,2, 1,2. 3, 5, 6, 2, 1, 7, 6, 3,2

A page fault will occur when a program accesses a page that is mapped in the virtual address space, but not loaded in physical memory .All the frames are initially empty, so your first unique page will cost one fault each.
What will be the number of the page faults, if the FIFO replacement policy is used with 3 page frames?
1)11
2)12
3)15
4)17

(#M40154330) AMCAT QUESTION Automata(C) Keep an EYE

Mooshak the mouse has been placed in a maze.There is a huge chunk of cheese somewhere in the maze.

The maze is represented as a two dimentional array of integers, where 0 represents walls.1 repersents paths where mooshak can move and 9 represents the huge chunk of cheese. Mooshak starts in the topleft corner at 0,0

Write a method isPath of class MazePath to determine if Mooshak can reach the huge chunk of cheese. The input to
isPath consists of a twodimentional
array grid for the maze matrix. the method should return 1 if there is a path
from Mooshak to the cheese.and 0 if not Mooshak is not allowed to leave the maze or climb on walls.
EX:8 by 8(8*8) matrix maze where Mooshak can get the cheese.
1 0 1 1 1 0 0 1
1 0 0 0 1 1 1 1
1 0 0 0 0 0 0 0
1 0 1 0 9 0 1 1
1 1 1 0 1 0 0 1
1 0 1 0 1 1 0 1
1 0 0 0 0 1 0 1
1 1 1 1 1 1 1 1
Test Cases:
Case 1:
Input:[[1,1,1,][9,1,1],[0,1,0]]
Expected return value :1
Explanation:
The piece of cheese is placed at(1,0) on the grid Mooshak can move from (0,0) to (1,0) to reach it or can move from (0,0) to (0,1) to (1,1) to (1,0)

Test case 2:
Input:
[[0,0,0],[9,1,1],[0,1,1]]
Expected return value:0
Explanation:
Mooshak cannot move anywhere as there exists a wall right on (0,0)

Code:
(C Language)
//include header files needed by your program
// some libray functionality may be restricted
// define any function needed
// fucion signature begins, this function is required
Int isPath(int **grid,int m,int n)
{
// write your code here
}

In a factory. the jobs are processed according to the priorities that are assigned to the jobs Priorities can be defined either internally or externally. Let us assume a job P is waiting for its turn but the higher priority jobs are preferred and P waits for its turn for a long time So now in this situation, either the Job P will run when the system has no jobs to process of higher priorities or the system will crash What is the solution of this problem?

1)Definate blocking
2)Aging
3)Preemption
4) Buffering
