Wide-mouth frog is the simplest known key distribution center (KDC) authentication protocol

C: \SAMPLE.EXE

Yes, it can be used, if an accurate clock frequency  is not required. also the component cost is low compared to LC or Crystal.

11

Because, on preprocessing the expression becomes  a = ( 3 + 2 * 2 + 3),  as Ist preference is multiply & then addition, it evalvates as(3+ 2 * 3 +2) = (3+6+2)=11.

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.

Glass Box (or white box) testing is the process of giving i/p to the system and checking how the system processes i/p to generate o/p

Black Box testing is the process of giving i/p to the system and checking if the system is giving correct o/p without bothering how the o/p is generated.

As we can see from the definitions, the role of black box testing is to ensure that the o/p generated is correct. And role of white box testing is to ensure that methods used to generate the o/p are correct.

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.
