Which operating system problem might cause the desktop background to change
unexpectedly? Choose the answer.
A boot failure
B startup loop
C malware D incompatibility

Answer:

d

Explanation:

If your computer freezes on a regular basis, and you have enough memory and that isn't causing a problem. You should install additional fans to cool the motherboard. The correct option is D.

Computer freezing means the computer is not running smoothly. It is causing concerns in opening any application or running software. It is also called computer hanging. The freezing can occur due to the heating of the motherboard. The addition of the fans would be good.

Freezing on the computer happens when the memories of the computer are full, or any virus has been installed on the computer. Hanging or freezing of computers can be avoided by emptying some data or installing an antivirus.

Thus, the correct option is D. Install additional fans to cool the motherboard.

Explanation:

Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.

Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.

Answer:

2. right below the application layer

Explanation:

TLS (Transport Layer Security) is an improved and more secured version of the SSL (Secure Socket Layer) used as cryptographic protocol for providing authentication and encryption over a network. It is initialized at the transport layer of the IP stack and finalized at the application layer. In other words, it is located between the transport and application layer of the Internet protocol stack. And this is necessary so that data received in the application layer from the transport layer are protected from start to end between these two layers.

Therefore, it is safe to say that the TLS is located right below the application layer.  

Answer:

C. ATA Secure Erase

D. Smash the USB drive

Explanation:

Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.

Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.

ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.

Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.

Answer:

deployment phase

Explanation:

This specific scenario belongs to the deployment phase of the hardware lifecycle. This phase is described as when the purchased hardware and software devices are deployed to the end-user, and systems implemented to define asset relationships. Meaning that everything is installed and set up for the end-user to be able to use it correctly.

Program starts here

#include<iostream>

#include<string>

using namespace std;

//The function get_ap_terms begins here

string get_ap_terms(int a, int d, int size_tn)

{  

// This line initializes the expected string to empty string

string result = "";

//The for iteration loops through the number of terms the function is expected to return

for(int i = 1; i<= size_tn;i++)

{

//This line checks if the loop is less than the number of  terms    

if(i < size_tn)

  {

//This string gets the current term of the progression

   result+=to_string(a)+ ", ";

//This line calculates the next term

   a+=d;  

  }

  else

  {

//This line calculates the last term

   result+=to_string(a);

  }

}

//This line returns the string containing the first n terms of the arithmetic progression

return result;

}

//The main function starts here

int main()

{

//This line declares the first term (a), the common difference (d) and the number of terms (size_tn)

int a,d,size_tn;

//This line prompts the user for the first term

cout<<"First Term: ";

//This line gets the first term

cin>>a;

//This line prompts the user for the common difference

cout<<"Common Difference: ";

//This line gets the common difference

cin>>d;

//This line prompts the user for number of terms

cout<<"Number of Terms: ";

//This line gets the number of terms

//This line calls the function to print the string containing the first n terms

The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?

def is_positive(number):

       if  _____ :

           return _____

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

---------------------------------------------------------------------------------

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

----------------------------------------------------------------------------------

The code above has been written in Python.

Now, let's explain each of the lines of the code;

Line 1: defines a function called is_positive which takes in a parameter number. i.e

def is_positive(number):

Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e

if (number > 0):

Line 3: returns a boolean value True if the number is positive. i.e

return True

Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e

else:

Line 5: returns a string value "None" if the number is not positive. i.e

return "None"

All of these put together gives;

===============================

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

================================

An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None

Following are the python program to check input number is positive or negative:

def is_positive(n):#defining the method is_positive that takes one variable in parameter

   if (n > 0):#defining if block that check input number is positive

       return True#return boolean value that is True

   else:#else block

      return "None"#return string value

n=int(input("Enter number: "))#defining n variable that input a number

print(is_positive(n))#using print method that calls and prints method return value
