If my computer has 4 gigabytes of ram memory then I have 4e+9 bytes of memory.  I think-

Answer: That isn't a software problem, its a hardware problem. There is a difference between 12gb of ram versus 100 gb of HDD. Ram is temporary storage, you can not turn SSD or HDD storage into RAM. If you are a gamer, STEER AWAY FROM LAPTOPS, DO NOT BUY A GAMING LAPTOP. Either buy a DESKTOP (or build) or a console. They give more performance for the price and they are easily upgradable. Not many people can open up a laptop and put in more RAM because the hardware is incredibly small.

Answer:

Here is the Python program.

def DigitList(number):  

   return sum(map(int, str(number)))  

list = [18, 23, 35, 43, 51]  

ascendList = sorted(list, key = DigitList)  

print(ascendList)

Explanation:

The method DigitList() takes value of numbers of the list as parameter. So this parameter is basically the element of the list. return sum(map(int, str(number)))  statement in the DigitList() method consists of three methods i.e. str(), map() and sum(). First the str() method converts each element of the list to string. Then the map() function is used which converts every element of list to another list. That list will now contain digits as its elements. In short each number is converted to the string by str() and then the digit characters of each string number is mapped to integers. Now these digits are passed to sum() function which returns the sum. For example we have two numbers 12 and 31 in the list so each digit is 1 2 and 3 1 are added to get the sum 3 and 4. So now the list would have 3 4 as elements.

Now list = [18, 23, 35, 43, 51] is a list of 5 numbers. ascendList = sorted(list, key = DigitList)  statement has a sorted() method which takes two arguments i.e. the above list and a key which is equal to the DigitList which means that the list is sorted out using key=DigitList. DigitList simply converts each number of list to a another list with its digits as elements and then returns the sum of the digits. Now using DigitList method as key the element of the list = [18, 23, 35, 43, 51] are sorted using sorted() method. print(ascendList) statement prints the resultant list with values in the list in ascending order sorted by the sum of their digits.

So for the above list [18, 23, 35, 43, 51] the sum of each number is 9 ,5, 8, 7, 6 and then list is sorted according to the sum values in ascending order. So 5 is the smallest, then comes 6, 7, 8 and 9. So 5 is the sum of the number 23, 6 is the sum of 51, 7 is the sum of 43, 8 is the sum of 35 and 9 is the sum of 18. So now after sorting these numbers according to their sum the output list is:

[23, 51, 43, 35, 18]                                                                                                          

Answer:

milespergallon = float(input())

dollarspergallon = float(input())

milestodrive = int(input())

trip_cost = milestodrive / milespergallon * dollarspergallon

print('Cost to drive {:d} miles at {:f} mpg at $ {:.2f}/gallon is: $ {:.2f}'.format(milestodrive, milespergallon, dollarspergallon, trip_cost))

Explanation:

Get the inputs from the user for milespergallon, dollarspergallon and milestodrive

Calculate the trip_cost, divide the milestodrive by milespergallon to get the amount of gallons used. Then, multiply the result by dollarspergallon.

Print the result as requested in the question

Answer:

def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon):

  gallon_used = driven_miles / miles_per_gallon

  cost = gallon_used * dollars_per_gallon  

  return cost  

miles_per_gallon = float(input(""))

dollars_per_gallon = float(input(""))

cost1 = driving_cost(10, miles_per_gallon, dollars_per_gallon)

cost2 = driving_cost(50, miles_per_gallon, dollars_per_gallon)

cost3 = driving_cost(400, miles_per_gallon, dollars_per_gallon)

print("%.2f" % cost1)

print("%.2f" % cost2)

print("%.2f" % cost3)

Answer:

c. Purging

Explanation:

Based on the information provided it can be said that the best method for sanitizing the data would be Purging. This is a process that permanently erases the data from a specific storage unit. Doing so prevents data from being recovered by an expert and also frees up storage and memory space to be used for other information. Since it is very inexpensive and provides the best overall results this would be the best option in this scenario.

Answer:

Linked lists and arrays are both linear data structures but while an array is a collection of items that can be accessed randomly, a linked list can be accessed sequentially.

A sparse matrix contains very few non-zero elements. For example;

_                        _

|  0   0   3  0  6    |

|   0   5   0  0  4   |

|   2   0   0  0  0   |

|_ 0   0   0  0  0 _|

In the implementation of a sparse matrix, the following are some of the pros and cons of using a linked list over an array;

PROS

i.  Linked lists are dynamic in nature and are readily flexible - they can expand and contract without having to allocate and/or de-allocated memory compared to an array where an initial size might need to be set and controlled almost manually. This makes it easy to store and remove elements from the sparse matrix.

ii. No memory wastage. Since the size of a linked list can grow or shrink at run time, there's no memory wastage as it adjusts depending on the number of items it wants to store. This is in contrast with arrays where you might have unallocated slots. Also, because the zeros of the sparse matrix need not be stored when using linked lists, memory is greatly conserved.

CONS

i. One of the biggest cons of linked lists is the difficulty in traversing items. With arrays, this is just of an order of 0(1) since the only requirement is the index of the item. With linked lists, traversal is sequential which means slow access time.

ii. Storage is another bottle neck when using linked lists in sparse matrix implementation. Each node item in a linked list contains other information that needs to be stored alongside the value such as the pointer to the next or previous item.

Explanation:

SONET is an acronym for synchronous optical networking while SDH is an acronym for synchronous digital hierarchy. They are both standard protocols used for the transmission of multiple digital bit streams (multiplex) synchronously through an optical fiber by using lasers.

Hence, both SONET and SDH are interoperable and typically the same standard protocols in telecommunication networks. Also, the SONET is a standardized protocol that is being used in the United States of America and Canada while SDH is an international standard protocols used in countries such as Japan, UK, Germany, Belgium etc.

The synchronous optical networking was developed in 1985 by Bellcore and it was standardized by the American National Standards Institute (ANSI). SDH was developed as a replacement for the plesiochronous digital hierarchy (PDH).

Generally, SONET comprises of four functional layers and these are;

1. Path layer

2. Line layer.

3. Section layer.

4. Physical or Photonic layer.

The SDH comprises of four synchronous transport modules and these are;

1. STM-1: having a basic data rate of 155.52Mbps.

2. STM-4: having a basic data rate of 622.08Mbps.

3. STM-16: having a basic data rate of 2488.32Mbps.

4. STM-64: it has a basic data rate of 9953.28Mbps.

These two standard telecommunications protocols are used to transmit large amounts of network data over a wide range through the use of an optical fiber.

Answer:

Here is the JAVA program to calculate volume of cuboid:

import java.util.Scanner; // Scanner class is used to take input from user

public class CuboidVol { // class to calculate volume of cuboid

public static void main(String[] args) { // start of main() function body

Scanner input= new Scanner(System.in); //create Scanner class object

// prompts user to enter length of cuboid

System.out.println("Enter the cuboid length:");

double length=input.nextDouble(); //reads the input length value from user

// prompts user to enter width of cuboid

System.out.println("Enter the cuboid width:");

double width=input.nextDouble(); //reads the input width from user

// prompts user to enter height of cuboid

System.out.println("Enter the cuboid height:");

double height=input.nextDouble(); //reads the input height from user

/* the following formula is to calculate volume of a cuboid by multiplying its length width and height and a double type variable cuboidVolume is defined to store the value of the resultant volume to it */

double  cuboidVolume= length*width*height; //calculates cuboid volume

//displays volume of cuboid and result is displayed up to 2 decimal places

System.out.printf("Volume of the cuboid (length " + length + "/ height " + height + "/ width" +width +" is: " + "%.2f",cuboidVolume);   } }

Explanation:

The formula for the volume of a cuboid is as following:

Volume = Length × Width ×  Height

So in order to calculate the volume of cuboid three variable are required for length, width and height and one more variable cuboidVolume to hold the resultant volume of the cuboid.

The program is well explained in the comments added to each statement of the program. The program prompts the user to enter the value of height width and length of cuboid and the nextDouble() method is used to take the double type input values of height length and width. Then the program declares a double type variable cuboidVolume to hold the result of the volume of cuboid. Then the last printf statement is used to display the volume of cuboid in the format format "Volume of the cuboid (length  / height  / width ) is" and the result is displayed up to 2 decimal places.

Deployment

Explanation:

Hardware lifecycle management is geared at making optimum use of the computer hardware so as to maximize all the possible benefits. During the deployment stage of the hardware lifecycle, the user is prompted by the computer to input their own computer hostname and username. In doing this, it is important that the user takes note of possible flaws in security. Passwords are set at this stage too. The four stages in the hardware lifecycle are procurement, deployment, maintenance, and retirement. At the deployment stage, the hardware is set up and allocated to employees so that they can discharge their duties effectively.

So, for organizations, it is important that strong passwords are used to prevent security breaches in the event that an employee leaves the organization.

The program written in Python is as follows

nums = []

for i in range(0,68):

-->nums.append(i)

print(nums)

Explanation:

Please note that --> is used to denote indentation

The first line creates an empty list

nums = []

This line creates an iteration from 0 to 67, using iterating variable i

for i in range(0,68):

This line saves the current value of variable i into the empty list

nums.append(i)

At this point, the list has been completely filled with 0 to 67

This line prints the list

print(nums)

(d) is used by Ping

Explanation:

ICMP is the short form of Internet Control Message Protocol. It is a protocol used by networking devices such as routers to perform network diagnostics and management. Since it is a messaging protocol, it is used for sending network error messages and operations information. A typical message could be;

i. Requested service is not available

ii. Host could not be reached

ICMP does not use ports. Rather it uses types and codes. Some of the most common types are echo request and echo reply.

Traceroute - which is a diagnostic tool - uses some messages available in ICMP (such as Time Exceeded) to trace a network route.

Ping - which is an administrative tool for identifying whether a host is reachable or not - also uses ICMP. The ping sends ICMP echo request packets to the host and then waits for an ICMP echo reply from the host.

ICMP is not required to solve NAT traversal problem neither does it have a new version in IPV6.

B) An approach to the evolutionary algorithm and its users are going to just have states M x N. But each state (i, j) indicates the absolute difference between the amount of the selected diamond and the amounts of the costs incurred.

DP(i, j) = DimondVal(i, j) + max ((DP(i, j-1)-2), (DP(i-1,j-1)-3))

DP(i, j) is a description of the state.

DimondVal(i, j) is the diamond value at (i j), 0 if there is no diamond available.

This states must calculate the states of M N  and it involves continuous-time for each State to determine. Therefore the amount of time of such an algo is going to be O(MN).
