Explanation:

The word Steganography is from the Greek word "Steganographia" where "Stego" means cover or concealed and "Graphia" means text/writing.

Steganography can be defined as data that is hidden within data. This simply means that, it is a cybersecurity technique used to hide information in another information and concealing the fact that a communication is in action or taking place.

In Computer science, Steganography is an encryption technique which is used alongside cryptography to cover or conceal the existence of a message (text) and render it un-intelligible to outsiders by transforming the message (text). Therefore, it is generally considered to be an extra-secure method to protect data from unauthorized access, use or piracy of copyright information. It is commonly used for audio, video and image files.

Hence, Steganography renders the message un-intelligible to outsiders by hiding it in a picture or other document.

Explanation:

A database such as SQL is considered as a well-structured group of information that is managed in a computer or server for easy access when needed to call upon.

Therefore, in any given database management, a lot of tasks can be done, among other several other features available is the HIDE and FREEZE functions.

Hence, a user can use the HIDE and FREEZE functions to prevent field columns from showing or to view two nonadjacent field columns for comparison in database management.

Hence, in this case, the correct answer to the statement presented is to HIDE and FREEZE

Answer:

1)

Add this while statement to the code:

while(keep_going!='n'):  

#the program keeps asking user to continue bidding until the user enter 'n' to stop.

2)

Here is the code for ACTIVITY 53.3. While loop: Insect growth:

num_insects = int(input())

while num_insects <= 100:

   print(num_insects, end=' ')

   num_insects = num_insects * 2

Explanation:

Here is the complete code for 1)

import random

random.seed (5)

keep_going='-'

next_bid = 0

while(keep_going!='n'):

   next_bid = next_bid + random.randint(1, 10)

   print('I\'ll bid $%d!' % (next_bid))

   print('continue bidding?', end='')

   keep_going = input()

Here the the variable keep_going is initialized to a character dash keep_going='-'

The statement keep_going = input() has an input() function which is used to take input from user and this input value entered by user is stored in keep_going variable. while(keep_going!='n'):  is a while loop that keeps iterating until keep_going is not equal to 'n'.    print('continue bidding?', end='')  statement prints the continue bidding? message on the output screen. For example the user enters 'y' when this message appears on screen. So keep_going = 'y' . So the operation in this statement next_bid = next_bid + random.randint(1, 10) is executed in which next_bid is added to some randomly generated integer within the range of 1 to 10 and print('I\'ll bid $%d!' % (next_bid))  prints the result on the screen. Then the user is prompted again to continue biffing. Lets say user enters 'n' this time. So keep_going = 'n'. Now the while loop breaks when user enters 'n' and the program ends.

2)

num_insects = int(input()) #the user is prompted to input an integer

while num_insects <= 100: #the loop keeps iterating until value of num_insects exceeds 100

   print(num_insects, end=' ') #prints the value of num_insects  

   num_insects = num_insects * 2 #the value of num_insects is doubled

For example user enters 8. So

num_insects = 8

Now the while loop checks if this value is less than or equal to 100. This is true because 8 is less than 100. So the body of while loop executes:

   print(num_insects, end=' ') statement prints the value of num_insects

So 8 is printed on the screen.

num_insects = num_insects * 2 statement doubles the value of num_insects So this becomes:

num_insects = 8 * 2

num_insects = 16

Now while loop checks if 16 is less than 100 which is again true so next 16 is printed on the output screen and doubled as:

num_insects = 16 * 2

num_insects = 32

Now while loop checks if 32 is less than 100 which is again true so next 32 is printed on the output screen and doubled as:

num_insects = 32 * 2

num_insects = 64

Now while loop checks if 64 is less than 100 which is again true so next 64 is printed on the output screen and doubled as:

num_insects = 64 * 2

num_insects = 128

Now while loop checks if 128 is less than 100 which is false so the program stops and the output is:

8 16 32 64  

The programs along with their output is attached.

This line initializes variable personindex to 0

personindex = 0

This line iterates from 1 to 10

for i in range(1,11):

The next two line prompts user for input

      print("Person ",i)

      pancake = int(input(": "))

This line inserts the user input to the created list "persons"

      persons.append(pancake)

The next if statement checks for the person with the most pancakes

      if pancake > most:

             most = pancake

             personindex = i

This line prints the person with most pancakes

print("Person ",personindex," ate most pancakes")

SingleClick

SingleClick is an Optical Character Recognition (OCR) tool that can be used to capture machine produced characters in low volume ad-hoc capture applications and populating a line of business application.

OCR (Optical Character Recognition)

OCR as a technology provides the ability to successfully capture machine produced characters in preset zones or, full page. OCR systems can recognise many different OCR fonts, as well as typewriter and computer-printed characters. Dependent upon the capabilities of the particular OCR product, this can be used to capture low to high volumes of data, where the information is in consistent location(s) on the documents. 

ICR (Intelligent Character Recognition)

ICR is the computer translation of hand printed and written characters. Data is entered from hand-printed forms through a scanner, and the image of the captured data is then analysed and translated by sophisticated ICR software. ICR is similar to optical character recognition (OCR) but is a more difficult process since OCR is from printed text, as opposed to handwritten characters.

Answer:

The feature of a server that makes it a potential and likely target of hacker attacks is it network capability.

Hackers are interested in attacking as many computers as possible.  Therefore, their best target is a server that serves the networked resources, computers, and systems.  From that point, their malwares can be distributed easily and smoothly to unsuspecting computer stations so that they in turn start replicating the malware and also malfunction.

Explanation:

Bear in mind that a server manages all network resources.  The storage capability resides in a server.  The security settings are usually installed in the server to serve all networked devices and systems.  It is from the server that all systems are administered.  Servers are usually dedicated to their server roles and nothing else.

Answer:

Social engineering.

Explanation:

To represent the 5 children as a computer bit, we make use of the equation [tex]2^b = n[/tex]. 3 bits are required to represent the 5 children.

Given that

[tex]n = 5[/tex] ---- number of children

The number of bits (b) is calculated as:

[tex]2^b = n[/tex]

Substitute 5 for n

[tex]2^b = 5[/tex]

Take logarithm of both sides

[tex]\log(2)^b = \log(5)[/tex]

Apply law of logarithm

[tex]b \times \log(2) = \log(5)[/tex]

Make b the subject

[tex]b = \frac{\log(5)}{\log(2)}[/tex]

[tex]b = 2.32[/tex]

The number of bits must be an integer. So, we use the greatest integer closest to 2.32. The integer is 3

So:

[tex]b=3[/tex]

Hence, the number of bits to represent the 5 children is 3.

Answer: C. Differential backup

Explanation: There are several ways od ensuring the preservation and storage of data even cases of disaster, one of such ways is data data mirroring which allows data to be replicated or copied in real time and several backup options. In cases where there there is need to restore a server, the warm recovery site provides a data or disaster recovery option used to mitigate the effect of data loss on organization. In the absence of data mirroring, differential backup option, provides the quickest recovery option as it only requires changes in the data stored after the last full backup. These speed experieced should be expected due to the relatively low data been dealt with rather than the entire data.

Answer:

Add this statement to the code using format method:

result = "{} miles equals {:.1f} km".format(miles,km)

Explanation:

Here is the complete program:

def convert_distance (miles):

   km = miles * 1.6

   result = "{} miles equals {:.1f} km".format(miles,km)

   return result    

print(convert_distance(12))# should be: 12 miles equals 19.2 km

print(convert_distance(5.5)) # should be: 5.5 miles equals 8.8 km

print(convert_distance(11)) # Should be: 11 miles equals 17.6 km

The format() method is used to format the values of the specified parameters and insert the formatted values into the curly brackets which are called placeholders. The parameters of format() method here are miles and km . The first placeholder is for formatted value of miles variable and second placeholder is for formatted value of km variable. Note that placeholder for km has {:.1f} which means the value of km is rounded to 1 decimal place. For example if the value is 19.23245 then it is displayed up to 1 decimal place as: 19.2

The above program has a method convert_distance that takes miles as parameter and converts the value of miles to km by formula:

km = miles * 1.6

It then displays the output in the specified format using format() method. Now lets take an example:

print(convert_distance(5.5))

The above statement calls the method by passing the value 5.5 So,

miles = 5.5

Now the function converts this value to km as:

km = miles * 1.6

km = 5.5 * 1.6

km = 8.8

Statement: result = "{} miles equals {:.1f} km".format(miles,km) becomes:

{} first place holder holds the value of miles i.e. 5.5

{} second place holder holds the value of km up to 1 decimal place i.e. 8.8

Hence it becomes:

5.5 miles equals 8.8 km

So return result  returns the result of this conversion.

Hence the output is:

5.5 miles equals 8.8 km

The program and its output is attached.

The format method is used to substitute and format output data before they are eventually printed.

The complete statement using the format method is:

result = "{} miles equals {:.1f} km".format(miles,km)

From the question, we understand that the program is to output the converted distance to 1 decimal place.

The function definition receives miles as its argument, while the equivalent distance in kilometers is calculated within the function.

Answer:

Encrypted message: CPONYIERTN

Explanation:

Message = ENCRYPTION

keyword = ONE

keyword ONE is of length 3 so the rows are of length 3

Permutation is given by the alphabetical order of the letters in the keyword ONE. Here E appears first in alphabet, then comes N and in last comes O so the order would be 321.

Now the message ENCRYPTION is written in tabular form with width of the rows defined by a keyword ONE

O     N     E

3      2      1

E      N     C

R      Y     P

T       I     O

N

Now this message is read by the column in alphabetic order of the keyword ONE.

Since alphabetic order of E is 1 so the column under E is read first which has the letters:

CPO

Then column under N is read which has the letters:

NYI

In the last the column under O is read which has the letters:

Answer:

A. True.

Explanation:

Authentication in computer technology can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.

Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification

Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.

Hence, if the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing.

This simply means that, when a user enters his or her private key (password); the authenticator matches the private key to the uniquely defined credentials. Permission and access is granted by the authorization system right after a successful authentication.
