Answer:
b. AES
Explanation:
AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.
It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).
Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.

Discuss the different types of user-friendly interfaces and the types of users who typically use each.
Answer:
1. Natural Language Interface- Telephone users
2. Menu Driven Interface- Automated Teller machine users.
3. Graphic User Interface- Computer users
4. Form-based interface- Website visitors
5. Command-line interface- Advanced users of computers
Explanation:
User interface refers to the hardware and software features in a computer system which makes it easier for the operators to relate with the system. Some of them include;
1. Natural Language Interface- This software feature allows the user to send oral instructions to the computer system. Telephone users experience this when they give oral commands to their phones.
2. Menu Driven Interface- Contains buttons and a touch screen feature that allows users to enter commands in a menu. Automated teller machines used by bank customers are menu-driven interfaces.
3. Graphic User Interphase- Involves the use of the cursor to draw images using graphic icons. Graphic designers can use this to create images.
4. Form-based Interface- Basically contains fields with boxes and menus that would need to be completed. For example, job seekers have to complete fields and boxes before they submit a job application form online.
5. Command-line interface- Is characterized by basic commands which are to be entered by the user to the computer. Advanced users of computes use this feature.
Write a program to compute answers to some basic geometry formulas. The program prompts the user to input a length (in centimeters) specified as a floating point value. The program then echoes the input and computes areas of squares and circles and the volume of a cube. For the squares, you will assume that the input length value is the length of a side. For the circles, this same value becomes the diameter. Use the meter value input to calculate the results in square (or cubic) meters and then print the answers in square (or cubic) meters.
Answer:
import math
l = float(input("Enter length in cm: "))
l = l / 100;
print("Entered length is " + str(l) + " meters")
area_square = l * l
print("Area of square is " + str(area_square))
area_circle = math.pi * l/2 * l/2
print("Area of circle is " + str(area_circle))
volume_cube = l * l * l
print("Volume of cube is " + str(volume_cube))
Explanation:
*The code is in Python
Ask the user to enter the length in cm
Convert the length to meters and print it
Calculate the area of the square and print it (Since length is equal to a side, the area is length * length)
Calculate the area of the circle and print it (Since length is equal to the diameter, you need to divide it by two to get the radius. The area is pi * length/2 * length/2)
Calculate the volume of the cube and print it (Since length is equal to a side, the volume is length * length * length)

C# The video game machine at your local arcade output coupons according to how well you play the game. You can redeem 10 coupons for a candy bar or 3 coupons for a gumball. You prefer candy bars to gumballs. Write a program that defines a variable initially assigned to the number of coupons you win. Next, the program should output how many candy bars and gumballs you can get if you spend all of your coupons on candy bars first, and any remaining coupons on gumballs.
Answer:
#include<iostream>
using namespace std;
/* main is a function without a parameters which returns an int value*/
int main( )
{
/* declare int data type for numeric values initialize candyBar and gumBall */
int coupons, cabdyBr=10,gumall=3;
int candyBarAmount,gumBallAmount,remainder;
/* cout is used to show the message to user cin to read user input from keyboard and sets the value to coupon */
cout<<"Enter the number of coupons"\t";
cin>>coupons;
/* First check coupons with cabdyBar */
if (coupons >= candyBar)
{
candyBarAmount=coupons/candyBar;
remainder=coupons-(candyBarAmount*10);
}
else
{
candyBarAmount=0;
}
/* check remaining value with gumBall */
if (remainder<<candyBar && remainder>=gumBall)
{
gumBallAmount=remainder/gumball;
}
else
{
gumBallAmount=0;
}
/* show thw required output to the user */
cout<<"The number of Candy bars is "<< candyBarAmount <<endl;
cout<<"The number of gumballs is "<<gumballAmount <<endl;
/* The program ends and return 0 as the functions value */
return 0;
}
OUTPUT
Enter the number of coupons: 23
The number of candy bars = 2
The number of gumballs = 1

_________ attacks are becoming less common in modern operating systems.
a. Denial of service
b. SYN flood
c. Buffer overflow
d. None of the above
Answer:
c. Buffer overflow
Explanation:
In Computer programming, buffer can be defined as an area of memory set aside specially and specifically for holding data or informations.
A type of exploit that relies on overwriting contents of memory to cause unpredictable results in an application is known as buffer overflow. This ultimately implies that, buffer overflow is the process of exceeding the storage capacity of a memory buffer with data, beyond the amount it is designed to hold and therefore overwrites any adjacent memory locations.
Buffer overflow attacks are becoming less common in modern operating systems because the modern operating system usually leaves a space between buffers and randomize the layout of memory through call mapping, as well as through the use of runtime protection.
