Q:

Bright light is found to emit from photographer’s flashgun. This brightness is due to the presence of which one of the following noble gases?

A) Argon B) Xenon
C) Neon D) Helium
 
Answer & Explanation Answer: B) Xenon

Explanation:

Electronic Flash differs from the consumable bulb flash in important aspects. Instead of creating light by burning up in an atmosphere containing oxygen, a consumable material (each bulb being used therefore only once), it produces a brilliant incandescent by discharging a current for a brief instant through a rarified gas, usually xenon. The gas glows every time the discharge is made through it but it is not consumed, so that many thousands of flashes are obtainable from a single tube, which helps to offset the much higher cost of the initial apparatus.

Q:

What are the different job scheduling in operating systems?

Answer

Scheduling is the activity of the deciding when process will receive the resources they request.


FCS ---> FCSFS stands for First Come First Served. In FCFS the job that has been waiting the longest is served next.


Round Robin Scheduling--->Round Robin scheduling is a scheduling method where each process gets a small quantity of time to run and then it is preempted and the next process gets to run. This is called time-sharing and gives the effect of all the processes running at the same time


Shortest Job First ---> The Shortest job First scheduling algorithm is a nonpreemptive scheduling algorithm that chooses the job that will execute the shortest amount of time.


Priority Scheduling--->Priority scheduling is a scheduling method where at all times the highest priority process is assigned the resource.

Write a program for matrix multiplication in c

Answer

#include <stdio.h>


int main() {


  int a[5][5], b[5][5], c[5][5], i, j, k, sum = 0, m, n, o, p;


  printf( "\nEnter the row and column of first matrix" );


  scanf( "%d %d", &m, &n );


  printf( "\nEnter the row and column of second matrix" );


  scanf( "%d %d", &o, &p );


  if(n!=o) {


      printf( "Matrix mutiplication is not possible" );


      printf( "\nColumn of first matrix must be same as row of second matrix" );


  }


  else {


      printf( "\nEnter the First matrix" );


      for( i=0; i<m; i++ )


      for( j=0; j<n; j++ )

           sum = 0;

               sum = sum + a[i][k]*b[k][j];


           c[i][j] = sum;


      }


      }


  }


  printf( "\nThe multiplication of two matrix is\n" );


  for( i=0; i<m; i++ ) {


      printf("\n");


      for( j=0; j<p; j++ ) {


           printf( "%d\t", c[i][j] );
