Answer: Provided in the explanation segment

Explanation:

Below is the code to carry out this program;

/* C++ program helps prompts user to enter the size of the array. To display the array elements, sorts the data from highest to lowest, print the lowest, highest and average value. */

//main.cpp

//include header files

#include<iostream>

#include<iomanip>

using namespace std;

//function prototypes

void displayArray(int arr[], int size);

void selectionSort(int arr[], int size);

int findMax(int arr[], int size);

int findMin(int arr[], int size);

double findAvg(int arr[], int size) ;

//main function

int main()

{

const int max=50;

int size;

int data[max];

cout<<"Enter # of scores :";

//Read size

cin>>size;

/*Read user data values from user*/

for(int index=0;index<size;index++)

{

cout<<"Score ["<<(index+1)<<"]: ";

cin>>data[index];

}

cout<<"(1) original order"<<endl;

displayArray(data,size);

cout<<"(2) sorted from high to low"<<endl;

selectionSort(data,size);

displayArray(data,size);

cout<<"(3) Highest score : ";

cout<<findMax(data,size)<<endl;

cout<<"(4) Lowest score : ";

cout<<findMin(data,size)<<endl;

cout<<"(5) Lowest scoreAverage score : ";

cout<<findAvg(data,size)<<endl;

//pause program on console output

system("pause");

return 0;

}

/*Function findAvg that takes array and size and returns the average of the array.*/

double findAvg(int arr[], int size)

{

double total=0;

for(int index=0;index<size;index++)

{

total=total+arr[index];

}

return total/size;

}

/*Function that sorts the array from high to low order*/

void selectionSort(int arr[], int size)

{

int n = size;

for (int i = 0; i < n-1; i++)

{

int minIndex = i;

for (int j = i+1; j < n; j++)

if (arr[j] > arr[minIndex])

minIndex = j;

int temp = arr[minIndex];

arr[minIndex] = arr[i];

arr[i] = temp;

}

/*Function that display the array values */

void displayArray(int arr[], int size)

{

for(int index=0;index<size;index++)

{

cout<<setw(4)<<arr[index];

}

cout<<endl;

}

/*Function that finds the maximum array elements */

int findMax(int arr[], int size)

{

int max=arr[0];

for(int index=1;index<size;index++)

if(arr[index]>max)

max=arr[index];

return max;

}

/*Function that finds the minimum array elements */

int findMin(int arr[], int size)

{

int min=arr[0];

for(int index=1;index<size;index++)

if(arr[index]<min)

min=arr[index];

return min;

}

Assume that a large number of consecutive IP addresses are available starting at 198.16.0.0 and suppose that two organizations,

Fiesta28 [93]

Answer & Explanation:

An IP version 4 address is of the form w.x.y.z/s

where s = subnet mask

w = first 8 bit field, x = 2nd 8 bit field, y = 3rd 8 bit field, and z = 4th 8 bit field

each field has 256 decimal equivalent. that is

binary denary or decimal

11111111 = 2⁸ = 256

w.x.y.z represents

in binary

11111111.11111111.11111111.11111111

in denary

255.255.255.255

note that 255 = 2⁸ - 1 = no of valid hosts/addresses

there are classes of addresses, that is

class A = w.0.0.0 example 10.0.0.0

class B = w.x.0.0 example 172.16.0.0

class C = w.x.y.0 example 198.16.8.1

where w, x, y, z could take numbers from 1 to 255

Now in the question

we were given the ip address : 198.16.0.0 (class B)

address of quantity 4000, 2000, 8000 is possible with a subnet mask of type

255.255.0.0 (denary) or

11111111.11111111.00000000.00000000(binary) where /s = /16 That is no of 1s

In a VLSM (Variable Length Subnet Mask)

Step 1

we convert the number of host/addresses for company A to binary

4000 = 111110100000 = 12 bit

step 2 (subnet mask)

vary the fixed subnet mask to reserve zeros (0s) for the 12 bit above

fixed subnet mask: 11111111.11111111.00000000.00000000 /16

variable subnet mask: 11111111.11111111.11110000.000000 /20

now we have added 4 1s in the 3rd field to reserve 12 0s

subnet mask: 255.255.16.0 (where the 1s in each field represent a denary number as follows)

1st 1 = 128, 2nd 1 = 64 as follows

1 1 1  1  1 1 1 1

128 64 32 16 8 4 2 1

step 3

in the ip network address: 198.16.0.0/19 (subnet representation) we increment this using 16

that is 16 is added to the 3rd field as follows

That means the ist Valid Ip address starts from

Ist valid Ip add: 198.16.0.1 - 198.16.15.255(last valid IP address)

Company B starts+16: 198.16.16.0 - 198.16.31.255

+16: 198.16.32.0- 198.16.47.255 etc

we repeat the steps for other companies as follows

Company B

Step 1

we convert the number of host/addresses for company B to binary

2000 = 11111010000 = 11 bit

Step 2

vary the fixed subnet mask to reserve zeros (0s) for the 11 bit above

fixed subnet mask: 11111111.11111111.00000000.00000000 /16

variable subnet mask: 11111111.11111111.11111000.000000 /21

now we have added 5 1s in the third field to reserve 11 0s

subnet mask: 255.255.8.0 (where the 1s in each field represent a denary number as follows)

1st 1 = 128, 2nd 1 = 64 as follows

1 1 1 1 1  1 1 1

128 64 32 16 8  4 2 1

Step 3

Starting from after the last valid Ip address for company A

in the ip network address: 198.16.16.0/21 (subnet representation) we increment this using 8

That means the ist Valid Ip address starts from

Ist valid Ip add: 198.16.16.1 - 198.16.23.255(last valid IP address)

Company C starts +16: 198.16.24.0- 198.16.31.255

+16: 198.16.32.0- 198.16.112.255 etc

Company C

Step 1

we convert the number of host/addresses for company C to binary

4000 = 111110100000 = 12 bit

Step 2

vary the fixed subnet mask to reserve zeros (0s) for the 12 bit above

fixed subnet mask: 11111111.11111111.00000000.00000000 /16

variable subnet mask: 11111111.11111111.11110000.000000 /20

now we have added 4 1s in the 3rd field to reserve 12 0s

subnet mask: 255.255.16.0 (where the 1s in each field represent a denary number as follows)

1st 1 = 128, 2nd 1 = 64 as follows

1 1 1 1 1 1 1 1

128 64 32 16 8 4 2 1

Step 3

Starting from after the last valid ip address for company B

in the ip network address: 198.16.24.0/20 (subnet representation) we increment this using 16

That means the ist Valid Ip address starts from

Ist valid Ip add: 198.16.24.1 - 198.16.39.255(last valid IP address)

Company C starts +16: 198.16.40.0- 198.16.55.255

+16: 198.16.56.0- 198.16.71.255 etc

Company D

Step 1

we convert the number of host/addresses for company D to binary

8000 = 1111101000000 = 13 bit

Step 2

vary the fixed subnet mask to reserve zeros (0s) for the 13 bit above

fixed subnet mask: 11111111.11111111.00000000.00000000 /16

variable subnet mask: 11111111.11111111.11100000.000000 /19

now we have added 3 1s in the 3rd field to reserve 13 0s

subnet mask: 255.255.32.0 (where the 1s in each field represent a denary number as follows)

1st 1 = 128, 2nd 1 = 64 as follows

1 1  1  1 1 1 1 1

128 64 32  16 8 4 2 1

Step 3

Starting from after the last valid ip address for company C

in the ip network address: 198.16.40.0/20 (subnet representation) we increment this using 32

That means the ist Valid Ip address starts from

Ist valid Ip add: 198.16.40.1 - 198.16.71.255(last valid IP address)

Company C starts +16: 198.16.72.0- 198.16.103.255

+16: 198.16.104.0- 198.16.136.255 etc

Which type of page of replacement algorithm is Windows XP and Unix are using?

mel-nik [20]

Answer:

Windows XP uses the Local Page Replacement algorithm. It is a type of FIFO. In this, Pages are taken from processes using more than their minimum working set and Processes initialize with a default of 50 pages. XP monitors page fault rate and adjusts working set size accordingly.

UNIX uses the Global replacement Algorithm through Modified second-chance clock algorithm. Here Pages are aged with each second and Pages that are not used for a long time will eventually have a value of zero.

"How has graphic design changed through time?"

noname [10]

The main purpose behind graphic designing is to communicate, The different colors, shapes and patterns used in graphics aim to deliver a meaningful message, which sometimes is hidden. Back in the time, graphic designs usually portrayed what was going on at that time, for instance wars, with larger icons and catchy slogans. Over the time, the graphic designs have evolved where psychedelic, geometrical and monochromatic designs have gained more popularity, with different typographic styles to follow. Moreover, since the world has been taken over by technology in a storm, we get to see some drastic changes in the photography styles, use of color balances with minimal designs and subtle tones.
