Answer:
I think it's MyDoom?? I heard it's the most dangerous cyber attack in history since it caused 38 billion dollars.
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved by executing cout << fixed << setprecision(2); once before all other cout statements.
Answer:
Explanation:
The following is written in C++ and asks the user for inputs in both miles/gallon and dollars/gallon and then calculates the gas cost for the requested mileages using the input values
#include <iostream>
#include <iomanip>
using namespace std;
int main () {
// distance in miles
float distance1 = 20.0, distance2 = 75.0, distance3 = 500.0;
float miles_gallon, dollars_gallon;
cout << "Enter cars miles/gallon: "; cin >> miles_gallon;
cout << "Enter cars dollars/gallon: "; cin >> dollars_gallon;
cout << "the gas cost for " << distance1 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance1 / miles_gallon << "$\n";
cout << "the gas cost for " << distance2 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance2 / miles_gallon << "$\n";
cout << "the gas cost for " << distance3 << " miles is " << fixed << setprecision(2) << (float) dollars_gallon * distance3 / miles_gallon << "$\n";

1. Add the following method to the Point class:
public double distance(Point other)
Returns the distance between the current Point object and the given other Point object. The distance between two points is equal to the square root of the sum of the squares of the differences of their x- and y-coordinates. In other words, the distance between two points (x1, y1) and (x2, y2) can be expressed as the square root of (x2 - x1)2 + (y2 - y1)2. Two points with the same (x, y) coordinates should return a distance of 0.0.
public class Point {
int x;
int y;
// your code goes here
}
2. Create a class called Name that represents a person's name. The class should have fields named firstName representing the person's first name, lastName representing their last name, and middleInitial representing their middle initial (a single character). Your class should contain only fields for now.
3. Add two new methods to the Name class:
public String getNormalOrder()
Returns the person's name in normal order, with the first name followed by the middle initial and last name. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "John Q. Public".
public String getReverseOrder()
Returns the person's name in reverse order, with the last name preceding the first name and middle initial. For example, if the first name is "John", the middle initial is 'Q', and the last name is "Public", this method returns "Public, John Q.".
4. Add the following method to the Point class:
public int quadrant()
Returns which quadrant of the x/y plane this Point object falls in. Quadrant 1 contains all points whose x and y values are both positive. Quadrant 2 contains all points with negative x but positive y. Quadrant 3 contains all points with negative x and y values. Quadrant 4 contains all points with positive x but negative y. If the point lies directly on the x and/or y axis, return 0.
public class Point {

Assume the data link protocol used by NDAS has the following associated characteristics:
An 8-bit ASCII code is used. Each frame has a size (length) of 11936 bits. A half-duplex circuit with a speed of 1 million bits per second is used for transmission. There is a 30-millisecond turnaround time on the half-duplex circuit. Each frame contains 20 overhead (non-user-data) bytes. Assume that the probability of a frame requiring retransmission due to error in transmission is 1 percent. A millisecond is one-thousandth of a second. Also, 8 bits = 1 character = 1byte
Fill in the blanks
K= _________ bits per bytes
M=_________ bytes
C= _________ overhead bytes
Answer:
The transmission speed = 0.278 MB/s
Explanation:
K = 8 bits
M = 11936/8 bits = 1492 bits
transmission rate R = 1000000/ 8 = 125000 bps
overhead bytes C = 20
probability = 0.01
time T = 30 ms = 30 x10^-3 s
The data transmission speed formula = K(M-C)(1-p) / (M/R) + T
= 8( 1492 - 20)(0.99)/ (1492/125000) + 30 x10^-3
= 0.278 MB/s

An administrator wants to restrict access to a particular database based upon a stringent set of requirements. The organization is using a discretionary access control model. The database cannot be written to during a specified period when transactions are being reconciled. What type of restriction might the administrator impose on access to the database
Answer:
Time of the day and object restrictions
Explanation:
From the question, we understand that the database is not allowed to be accessed at a certain period of time.
Because this has to do with time (period), the administrator will need to set a time of the day object restriction on the database in order to prevent the users from accessing the database objects

Explanation:
The child’s game, War, consists of two players each having a deck of cards. For each play, each person turns over the top card in his or her deck. The higher card wins that round of play and the winner takes both cards. The game continues until one person has all the cards and the other has none. Create a program that simulates a modified game of War.
The computer will play both hands, as PlayerOne and PlayerTwo, and, for each round will generate two random numbers and compare them.
If the first number is higher, PlayerOne’s score is increased by 1 and if the second number is higher, PlayerTwo’s score is increased by 1.
If there is a tie, no score is incremented.
When one "player" reaches a score of 10, that player should be deemed the winner and the game ends.
The range of numbers should be 1-13 to simulate the values of cards in the deck.
Answer:
In Python
import random
p1 = 0; p2 =0

how to learn python ?
Answer:
See below.
Explanation:
To learn python programming language, first, you have to know the basic. Surely, you may recognize this function namely print()
print(“Hello, World!”) — output as Hello, World!
First, start with familiarizing yourself with basic function such as print. Then step up with arithmetic and declare or assign variable then list.
Here are example of functions:
1.) print(argument) — If argument is a string (word-typed), make sure to use “” or ‘’ or else it’ll output an error and say the argument is not defined.
print(“Hi, Brainly”) will output Hi, Brainly
print(2+3) will output 5
Numerical data or numbers do not necessarily require “ “ or ‘ ‘
print(3+3) will output 6 but print(“3+3”) will output 3+3 which is now a string.
2.) type(argument) - this tells you which data/argument it is. There are
< class ‘str’ > which is string, meaning it contains “ “ or ‘ ‘< class ‘int’ > which is integer< class ‘float’ > which is decimal (20.0 is also considered as float, basically anything that contains decimal is all float type)< class ‘list’ > which is a list. List is something that contains elements within square brackets [ ]etc.
Make sure you also do print(type(argument)) as well so it will print out the output.
3.) Arithmetic
+ is additionEx. print(1+3) will output 4
2. - is subtraction
Ex. print(5-4) will output 1
3. * is multiply
Ex. print(4*5) will output 20
4. ** is exponent
Ex. print(5**2) will output 25
5. / is division
Ex. print(6/3) will output 2 — sometimes will output the float type 2.0
6. % is modulo or remainder
Ex. print(7%2) will output 1
4.) Variables
To assign a variable, use =
An example is:
x = 2
y = 5
print(x+y) will output 7
print(type(x)) will output the < class ‘int’ >
These are examples of what you’ll learn in basic of python - remember, programming depends on experience and always focus on it. Keep practicing and searching will improve your skill at python.
Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, and C) in the instruction set. M1 has a clock rate of 60MHz and M2 has a clock rate of 80MHz. The average number of cycles of each instruction class and their frequencies (for a typical program) are as follows:
Instruction Class M1-cycles M2-cycles/ Frequency
/instruction class instruction class
A 1 2 50%
B 2 3 20%
C 3 4 30%
a. Calculate the average CPI for each machine, M1 and M2.
b. Calculate the CPU execution time of M1 and M2.
Explanation:
A.)
we have two machines M1 and M2
cpi stands for clocks per instruction.
to get cpi for machine 1:
= we multiply frequencies with their corresponding M1 cycles and add everything up
50/100 x 1 = 0.5
20/100 x 2 = 0.4
30/100 x 3 = 0.9
CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8
We find CPI for machine 2
we use the same formula we used for 1 above
50/100 x 2 = 1
20/100 x 3 = 0.6
30/100 x 4 = 1.2
CPI for m2 = 1 + 0.6 + 1.2 = 2.8
B.)
CPU execution time for m1 and m2
this is calculated by using the formula;
I * CPI/clock cycle time
execution time for A:
= I * 1.8/60X10⁶
= I x 30 nsec
execution time b:
I x 2.8/80x10⁶
= I x 35 nsec

Bugs always seem to creep into programs and code. What strategies have you learned to find bugs more easily and crush them with a fix?
The process involves in finding bugs as well as crushing them in a debugging process is extensive and this can consist of following process;
Examination of the error symptoms
identifying the cause of it
fixing of the error.
This process is usually required a large amount of work, Although no precise procedure that is set in for fixing all error, but some useful strategies that use in reducing the debugging effort.
One of the significant part of this process is localizing of the error, which is figuring out the cause as well as the symptoms. Strategies that I have learnt in finding and fixing the error in the process of debugging includes;Incremental as well as bottom-up program development; development of the program incrementally remains one of the most effective ways that can be used in localizing the error, often testing as the piece of code is added, so with this it will be easier to find the error since any error is from the last piece of code added.And also since the last fragment of the code will be small then searching for bugs won't take much time to find and debug.Bottom-up development helps in maximizing the benefits that comes from incremental development. With bottom-up development, after successful testing of a code, it's behavior will not change once another piece is added to it, since existing code will never replied on new part so it will be easier to trace error in the new code and fix it.Instrument program can be used to log information and there can be insertion of print statements.Instrument program using assertions; Assertions can be used in checking if the program actually maintains the properties or those invariant that the code relies on, Because the program will definitely stops once the assertion fails, and there is actuality that the point where the program reached and stops is closer to the cause, as well as good indicator of how the problem looks like , then the bug can then be fixed.breakpoints can be set in the program as well as stepping and over functions, then watching program expressions, as well as inspection of the memory contents at a particular point during the execution can give the needed run-time information.Backtracking: this option works in a way whereby one will need to start from the point that the problem occurred then go back through the code to to detect the issue, then the bug can then be fixed.Binary search: this is exploration of the code by using divide and conquer approach, so that the the bug be pin down quickly.Therefore, Bugs are treat to programs and they can be dealt with using discussed methods.

The computer scientists Richard Conway and David Gries once wrote: The absence of error messages during translation of a computer program is only a necessary and not a sufficient condition for reasonable [program] correctness. Rewrite this statement without using the words necessary or sufficient.
Answer:
A computer program is not reasonably correct if it has no error messages during translation.
Explanation:
First, we need to understand what the statement means, and we also need to identify the keywords.
The statement means that, when a program does not show up error during translation; this does not mean that the program is correct
