what level of security access should a computer user have to do their job?

Answer:

the issued Automatic Private IP Addressing (APIPA) address.

Explanation:

Since we are told that the user was able to access the network resources yesterday, and all the network equipment in the user's computer is functioning properly, there is a very high possibility that because the user's computer has been issued an Automatic Private IP Addressing (APIPA) address, it affected his computer's ability to connect to a public network.

This is the case because private network IP addresses are known to prevent inflow and outflow of data onto public networks.

Explanation:

The DNS server is said to be a caching-only DNS server.

A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.

Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.

The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.

Explanation: The operating system is a huge part of a computer system which plays a an invaluable role in the working of computer programs, hardwares and influences the overall experience of the user. It operating system serves as the interface between the computer hardware itself and the user who may wish to perform different tasks using a computer. In other to teach and learn, it is necessary to input and also obtain output, store our files and process and most essentially one may need to install application programs or softwares, all these functions are made possible with the help of an operating system. In essence, a system without an operating system can perform very little to no function at all. So basically teaching and learning becomes difficult. Teaching and Learning tools such as video, writing and other application softwares cannot be installed without an operating system and thus teaching or learning becomes impossible in it's absence.

Depending on the software that Raj was using to create his project he should first see if the software itself saved the project. Usually many software such as those included in the Microsoft Office Suite save the file automatically every 5 minutes or so in case of a power outage or abrupt closure of the file. If this is not the case he should try and do a system restore with the unlikely hope that it restores an older version of his project.

In a situation like this, it would be advisable for Raj to contact IT personnels and seek if the files could be retrieved.

Answer:

"Router screening" is the correct option.

Explanation:

So that the above seems to be the correct approach.

Answer:

This approach is not the same as letting the client execute a normal RPC

Explanation:

This approach is not the same as letting the client execute a normal RPC and this is because an asynchronous RPC sends an additional message across the network after the initial call/message is sent by the sender to the client. this additional message sent through the network is directed towards the sender of the initial call/message as an acknowledgement of the receipt of the initial message by the client .

synchronous RPC is made of two asychronous RPCs, hence the client executing a normal RPC  will not establish a reliable communication between the client and the sender as asynchronous RPC would

Answer:

Locality of reference.

Explanation:

In computing, The principle of locality of reference is the probability of a processor to repeatedly access the same set of memory locations within a small time interval. This reference of locality can be spatially based (repetitive usage of data within the same location on the computer memory), or temporally based (repetitive usage of a particular data or resources within a shot time interval). The ability of some computing system to perform this action increases their predictability, and efficiency of memory hierarchy use, among other abilities.

I am writing a Python program:

pi=3.14 #the value of pi is set to 3.14

radius = float(input("Enter the radius of sphere: ")) #prompts user to enter the radius of sphere

surface_area = 4 * pi * radius **2 #computes surface area of sphere

volume = (4.0/3.0) * (pi * radius ** 3) #computes volume of sphere

print("Surface Area of sphere is: ", surface_area) #prints the surface area

print("Volume of sphere is: {:.2f}".format(volume)) #prints the volume        

Explanation:

Please see the attachment for the complete interactive code.

The first three lines of print statement in the attached image give a brief description of the program.

Next the program assigns 3.14 as the value of π (pi). Then the program prompts the user to enter the radius. Then it computes the surface area and volume of sphere using the formulas. Then it prints the resultant values of surface area and volume on output screen.

The psuedocode for this program is given below:

PROGRAM SphereVolume

pi=3.14

NUMBER radius, surface_area, volume  

INPUT radius

COMPUTE volume = (4/3) * pi* radius ^3

COMPUTE surface_area = 4 * pi * radius ^ 2

OUTPUT volume , surface_area

def inputNumber():

   l = []

   num = int(input("Enter the number of integers you want to enter\n"))

   for i in range(0,num):

       print("Enter the ", i+1, " integers ")

       a = float(input())

       l.append(a)

   return l

def averageCalculator(l):

   total = 0

   for i in l:

       total += i

   avg = total/len(l)

   return avg

def printoutput(avg):

   print("The average of numbers is ", avg)

l = inputNumber()

avg = averageCalculator(l)

printoutput(avg)

Explanation:

A subprogram may be considered as a method where we pass some values in the arguments and return some value.

The answer is written in python language, where we have used

inputNumber() subprogram to get the input from the user.

function averageCalculator() to calculate the average.

printoutput() subprogram to print the output or the average of the numbers.

Please refer to the attached image for better understanding of the indentation of code.

Now, let us learn about them one by one:

inputNumber(): We get the number of values to be entered as an integer value and then get the numbers as float.

Store the values in a list and return the list to the caller main program.

averageCalculator(l): Contains a list as argument as we got from inputNumber(). It sums all the numbers and divides with total number to find the average. Returns the average value to the caller main program.

printoutput(avg): Contains an argument which is the average calculated in the averageCalculator(). It prints the argument passed to it.

Answer:

Here is the JAVA program. Let me know if you need the program in some other programming language.

import java.util.Scanner; // used for taking input from user

public class Main{ //Main class

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

  Scanner scan = new Scanner(System.in); // creates a Scanner type object

   String input; // stores input series

    int sum = 0; //stores the sum of the series

    System.out.println("Enter a series of numbers separated by commas: "); //prompts user to enter a series of numbers separated by comma

     input = scan.nextLine(); //reads entire input series

     String[] numbers = input.split("[, ]"); //breaks the input series based on delimiter i.e. comma and stores the split sub strings (numbers) into the numbers array

   for (int i = 0; i < numbers.length; i++) { //loops through each element of numbers array until the length of the numbers reaches

          sum += Integer.parseInt(numbers[i]); } // parses the each String element of numbers array as a signed decimal integer object and takes the sum of all the integer objects

     System.out.println("Sum of all the numbers: " + sum);  } } //displays the sum of all the numbers

Explanation:

The program prompts the user to enter a series separated by commas.

Then split() method is used to split or break the series of numbers which are in String form, into sub strings based on comma (,) . This means the series is split into separate numbers. These are stored in numbers[] array.

Next the for loop iterate through each sub string i.e. each number of the series, converts each String type decimal number to integer using Integer.parseInt and computes the sum of all these integers. The last print statement displays the sum of all numbers in series.  

If the input is 7,9,10,2,18,6

Then the output is: 7+9+10+2+18+6

sum = 52

The program and its output is attached.

Answer:

Here is the Python program:

def input_type(input_string): #function that takes a string as input and returns the type of that string

   try:   #used to test a block of code for input string type              

       if type(eval(input_string)) == float: #if the type of the string is float

           return "float" #function returns float

       elif type(eval(input_string)) == int: #else if the type of the string is int

           return "integer"#function return integers

       elif type(eval(input_string)) == bool:#else if the type of the string is bool

           return "boolean" #function return boolean

   except: #if the type of the string is neither int, bool nor float

       return "string" #function return boolean

#following statements are used to  test the working of the above function

print(input_type(" ")) #prints string

print (input_type ("False")) #prints boolean

print (input_type ("7.432621")) #prints  float

print (input_type("2788"))#prints int

Explanation:

The function input_type() takes a user input and returns the type of that string input the user entered. The user input can be one of the following types:

int which is the data type of an integer for example 1, 2, 3 etc

float which is the data type of a floating point number for example 1.2, 3.4 etc

bool which is the data type of a boolean for example True or False

string that can be characters for example an empty space character " "

try block here is used to generate an exception and it is used to test a block in the code that checks for the type of the user input. The except block here is used to handle that error. This is executed when the try part raises an error.

Inside the try block, the if and elif statements check the type of the string.

if type(eval(input_string)) == float: statement checks if the type of the string is float. Here the eval() method is used to convert the input string because the user input is basically a string value. So this method evaluates the input_string.

type() method is used to return the type of that evaluated user input string. If condition checks if type(eval(input_string)) which is the type of the evaluated input string is equal to float. If this condition evaluates to true then the function returns "float" otherwise it moves to the next elif statement. Similarly the type of the user input is checked for int in elif part and if both these if and elif conditions evaluate to false then the next elif statement is executed that checks the user input to be bool. If all these three if elif statements evaluate to false then the except part executes which returns "string". The program along with its output is attached in a screenshot.    

Answer:

The program written in Python is as follows:

See Explanation section for line by line explanation

for n in range(100,1000):

     isum = 0

     for d in range(1,n):

           if n%d == 0:

                 isum += d

     if isum == n * 2:

           print(n)

Explanation:

The program only considers 3 digit numbers. hence the range of n is from 100 to 999

for n in range(100,1000):

This line initializes sum to 0

     isum = 0

This line is an iteration that stands as the divisor

     for d in range(1,n):

This line checks if a number, d can evenly divide n

           if n%d == 0:

If yes, the sum is updated

                 isum += d

This line checks if the current number n is a double-perfect number

     if isum == n * 2:

If yes, n is printed

           print(n)

When the program is run, the displayed output is 120 and 672
