Answer:

The correct option is B.

Explanation:

Memory hierarchy is the ordering of storage systems according to their speed, capacity and cost.

The hierarchy consist of Register as the top, followed by cache, then main memory, secondary memory and external storage. As you go down the hierarchy, the speed decreases, the size increases and the cost decreases also.

Memory hierarchy diagram is attached for reference.

If a system's instruction set consists of an 8-bit opcode, what is the maximum number of output signal lines required for the co
otez555 [7]

Answer:

D. 256

Explanation:

Given

Instructions = 8\ bit

Required

Determine the maximum number of output

To get the required value, we make use of the following:

Maximum = 2^n

Where n is the bits of the opcode.

i.e.

n = 8

Substitute 8 for n in Maximum = 2^n

Maximum = 2^8

Maximum = 256

<em>Hence, option D answers the question</em>

The value of the mathematical constant e can be expressed as an infinite series: e=1+1/1!+1/2!+1/3!+... Write a program that app
LUCKY_DIMON [66]

Answer:

// here is code in c++ to find the approx value of "e".

#include <bits/stdc++.h>

using namespace std;

// function to find factorial of a number

double fact(int n){

double f =1.0;

// if n=0 then return 1

if(n==0)

return 1;

for(int a=1;a<=n;++a)

       f = f *a;

// return the factorial of number

return f;

}

// driver function

int main()

{

// variable

int n;

double sum=0;

cout<<"enter n:";

// read the value of n

cin>>n;

// Calculate the sum of the series

  for (int x = 0; x <= n; x++)

  {

     sum += 1.0/fact(x);

  }

  // print the approx value of "e"

    cout<<"Approx Value of e is: "<<sum<<endl;

return 0;

}

Explanation:

Read the value of "n" from user. Declare and initialize variable "sum" to store the sum of series.Create a function to Calculate the factorial of a given number. Calculate the sum of all the term of the series 1+1/1!+1/2!.....+1/n!.This will be the approx value of "e".

Output:

enter n:12

Approx Value of e is: 2.71828
