I WILL GIVE BRAINLIEST TO WHO ANSWERS FIRST AND CORRECTLY.

(--BRAINLIEST--) Explain the types of secondary memory on the basis of data access.

Nina [5.8K]

There are two types of secondary memories.

RAM
ROM

RAM:

RAM stands for random access memory .
It is expandable.
we can do multiple things in it.
Its erasable.

ROM

ROM stands for read only memory.
It is permanent .
We can only read in it.
Its permanent hence not removable.

Variance for accumulator. Validate that the following code, which adds the

Art [367]

Using the knowledge of computational language in JAVA it is possible to write a code that Validate that the following code, which adds the methods var() and stddev() to Accumulator, computes both the mean and variance of the numbers presented as arguments to addDataValue()

<h3>Writting the code:</h3>

import java.util.*;

public class Accumulator {

private static double m;

private static double v;

private static double st;

private static double s[]=new double[5];

private static int N;

private static int count =0;

public static void main(String[] args) {

// TODO Auto-generated method stub

Random r = new Random();

System.out.println("hello world");

for(int i=0;i<5;i++) {

double randomvalue = r.nextDouble();

addDataValue(randomvalue);

}

for(int i=0;i<s.length;i++) {

System.out.println("dataValue:"+s[i]);

}

mean();

System.out.println("mean:"+m);

var();

System.out.println("variance:"+v);

stddev();

System.out.println("standard deviation:"+st);

}

public static void addDataValue(double value) { // addes data values to array

s[count]=value;

count++;

}

public static double mean() { // returns mean

double sum=0.0;

for(int i=0;i<s.length;i++) {

sum+=s[i];

}

m = sum/s.length;

return m;

}

public static double var() { //returns variance

double mm = mean();

double t = 0;

for(int i=0;i<s.length;i++) {

t+= (s[i]-mm)*(s[i]-mm);

}

v= t/(s.length-1);

return v;

}

public static double stddev() { // returnsn the stardard deviation

st= Math.sqrt(var());

return st;

}

Secure software development: a security programmer's guide by jason grembi isbn-10: 1-4180-6547-1, isb-13: 978-1-4180-6547

a_sh-v [17]

Secure software development is known to be a kind of methodology (often linked with DevSecOps) for making software that incorporates a lot of security into every stage of the software development life cycle (SDLC).

<h3>What is secure software development practices?</h3>

Secure software development is seen as a method that is used form the creation of a lot of software that uses both security into all of the phase of the software development making cycle.

This book is known to be A Programmer's Guide that can be able to leads readers in all of the tasks and activities that one can do to be successful computer programmers and it is one that helps to navigate in the area of reading and analyzing requirements as well as choosing development tools, and others.

Hence, Secure software development is known to be a kind of methodology (often linked with DevSecOps) for making software that incorporates a lot of security into every stage of the software development life cycle (SDLC).
