What is the difference between a computer’s RAM and its hard disk?
A. RAM is not volatile, which means that it is more reliable than a hard disk. A hard disk is volatile, which means that it is vulnerable to electronic interference.

B. RAM is volatile, which means that it does not retain information in memory after powering down. A hard is not volatile, which means that it retains information in memory after powering down.

C. RAM is not volatile, which means that it retains information in memory after powering down. A hard disk is also not volatile, which means that it retains information in memory after powering down.

D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.

Answers

Answer 1

Answer:

D. RAM is volatile, which means that it must be handheld with care when removed or replaced. A hard disk is not volatile, which means that it is much more resistant to movement during removal or replacement.

Explanation:

Most RAM (random access memory) used for primary storage in personal computers is volatile memory. Volatile memory contrasts with non-volatile memory, which does not lose content when power is lost. Non-volatile memory has a continuous source of power and does not need to have its memory content periodically refreshed.

Answer 2

Answer:

Explanation:

RAM can be accessed faster than hard drive. – Any changes made to the file will be present in RAM while once the changes are saved it is copied to the hard drive permanently. – RAM needs power to store data, hard drives do not.

Without proper synchronization, which is possible, a deadlock, corrupted data, neither or both? Give reasons for your answer.
need answer pls​

Answers

Without proper synchronization, corrupted data is possible due to the fact that a shared datum can be accessible by multiple processes.

Data synchronization simply means the idea of keeping multiple copies of dataset in coherence with one another in order to maintain data integrity. It's the process of having the same data in two or more locations.

Without proper synchronization, corrupted data is possible because a shared datum could be accessed by multiple processes without mutual exclusive access.

Write the function void sort2(double* p, double* p) that receives two pointers and sorts the values to which they point. To test the function, write the main function that prompts the user to enter two values and then print out the sorted values. If you call sort2(&x, &y) then x <= y after the call.

Answers

The function illustrates the use of pointers.

Pointers are used to store address in programming languages such as C and C++.

The program in C language where comments are used to explain each line is as follows:

#include <stdio.h>

//This defines the function

void sort2(double* p1, double* p2){

   //This declares a temporary variable t

double t;

//If p2 is less than p1,

if (*p2 < *p1) {

    //The next 3 lines swap their values

    t = *p2;

    *p2 = *p1;

    *p1 = t;

}

//This prints p1

printf("%f ", *(p1));

//This prints p2

printf("%f ", *(p2));

}

//The main method to test the function begins here

int main(){

double x = 23.0;

double y = 14.1;

sort2(&x, &y);

return 0;

}

//The program ends here

The types of models in SDLC:

Generally, there are six (6) types of models in software development life cycle (SDLC) and these are:

Agile ModelV-Shaped ModelIterative ModelSpiral ModelBig Bang ModelWaterfall Model

What is a waterfall model?

In SDLC, a waterfall model refers to a process which involves the sequential breakdown of software development into linear stages (steps or phases). Thus, its development stages takes a downward flow like a waterfall and as such, each stage must be completed before starting another and without any overlap in the process.

Consider the following class. public class ClassicClass { private static int count = 0; private int num; public ClassicClass() { count++; num = count; } public String toString() { return count + " " + num; } } What is printed when the following code in the main method of another class is run? ClassicClass a = new ClassicClass(); ClassicClass b = new ClassicClass(); ClassicClass c = new ClassicClass(); System.out.println(a + ", " + b + ", " + c);

Answers

The the code in the main method is run, it will print

"3 1, 3 2, 3 3"

The static/class field count stores the number of instances of the class created. count is always incremented when the instance constructor is called.

The instance field num acts like an identifier/serial number for the instance created. When the constructor is called, the current count is stored in the num field of the instance.

Each instance's toString( ) method will output the total count (from count) and the serial of the instance (from num).

When the code runs in the main method, it creates three instances (making count==3), so that we have

a = {count: 3, num: 1}b = {count: 3, num: 2}c = {count: 3, num: 3}

and implicitly calls toString( ) in the println method for each of the three instances to produce the following output

"3 1, 3 2, 3 3"
