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.

Q:

Point out the error, ifany, in the followingb code?

typedef struct

{

     int data;

     NODEPTR link;

} *NODEPTR;

 

Answer

A typedef defines a new name for a type, and in simpler cases like the one shown below you can define a new structure type and a typedef for it at the same time.


typedef struct


{


    char name[20];


    int age;


} emp;


However, in the structure defined in this question, there is an error because a typedef declaration cannot be used until it is defined. In the given code fragment the typedef declaration is not yet defined at he point where the link field is declared.
