Answer:

Option A (Kernal) seems to be the right answer.

Explanation:

  • A Kernel appears to be the central component of such an OS. This handles machine as well as hardware activities, including most importantly storage as well as CPU power.
  • This manages the majority of the initialization as well as program input/output requests, converting them into CPU data-processing commands.

Declare a structure whose tag name is Server and that contains the following fields: manufacturer, a string, model and serialnum
NemiM [27]

Answer:

The answer to this question as follows :

Structure definition:

struct Server  //define structure server.

{

string manufacturer;

 //define string variable.

string model, serialnum;  //define string variable.

int year;

 //define integer variable.

double clockSpeed;

 //define double variable.

int cores;   //define integer variable.

int ram;

    //define integer variable.

int storage;

  //define integer variable.

};

Explanation:

Structure is a collection of heterogeneous(different type) elements. It is a user-define datatype which is available on the C/C++ programming language. To define any structure we use the struct keyword. The syntax of defining structure can be given as:

Syntax:

struct structure name

{

//define variables

//statements and code.

};

OR

struct structure name

{

//define variables

//statements and code.

}create structure variable;  

In the above structure code, we define a structure that is "Server". In this structure, we define different types of variables that is " manufacturer, model, serialnum, year, clockSpeed, cores, ram, and storage". In this structure variable manufacturer, model and serialnum datatype are a string and clockSpeed datatype is double and variable year, cores, ram, and storage data type is an integer.
