What is the leading use of computers?

Group of answer choices.

a. web surfing.

b. email, texting, and social networking.

c. e-shopping.

d. word processing.

e. management of finances.

Answer:

b. email, texting, and social networking.

Explanation:

Communication can be defined as a process which typically involves the transfer of information from one person (sender) to another (recipient), through the use of semiotics, symbols and signs that are mutually understood by both parties. One of the most widely used communication channel or medium is an e-mail (electronic mail).

An e-mail is an acronym for electronic mail and it is a software application or program designed to let users send texts and multimedia messages over the internet.

Also, social media platforms (social network) serves as an effective communication channel for the dissemination of information in real-time from one person to another person within or in a different location. Both email and social networking involves texting and are mainly done on computer.

Hence, the leading use of computer is email, texting, and social networking.

Tyrone Shoelaces has invested a huge amount of money into the stock market and doesnât trust just anyone to give him buying and selling information. Before he will buy a certain stock, he must get input from three sources. His first source is Pain Webster, a famous stock broker. His second source is Meg A. Cash, a self-made millionaire in the stock market, and his third source is Madame LaZora, world-famous psychic. After several months of receiving advice from all three, he has come to the following conclusions:

a) Buy if Pain and Meg both say yes and the psychic says no.

b) Buy if the psychic says yes.

c) Donât buy otherwise.

Construct a truth table and find the minimized Boolean function to implement the logic telling Tyrone when to buy.

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 {
private int x;
private int y;

A video game character can face toward one of four directions: north, south, east, and west. Each direction is stored in memory as a sequence of four bits. A new version of the game is created in which the character can face toward one of eight directions, adding northwest, northeast, southwest, and southeast to the original four possibilities. Which of the following statements is true about how the eight directions must be stored in memory?
A. Four bits are not enough to store the eight directions. Five bits are needed for the new version of the game.
B. Four bits are enough to store the eight directions
C. Four bits are not enough to store the eight directions. Sodeen bits are needed for the new version of the game.
D. Four bits are not enough to store the eight directions. Eight bits are needed for the new version of the game.

Write a Python program (rainfall.py) to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. Then for each year, the program should ask twelve times, once for each month, for inches of rainfall for that month. At the end, , the program should display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.

Your program should contain two functions:

(1) rainfall(year): This function takes in a year (integer) as a parameter, and returns two values (totalMonths and totalRainfall). In this function, you need to use nested loop. The outer loop will iterate once for each year. The inner loop will iterate twelve times, once for each month. Each iteration of the inner loop will ask the user for inches (float) of rainfall for that month. After all iterations, the function should return the number of months (totalMonths) and the total inches of rainfall (totalRainfall). (Submit for 4 points)

(2) __main__: In the main, you do the following: (Submit for 6 points)

a. Prompt the user to input the number of years. Reprompt the user if the number of years is 0 or less. Hint: use a while loop.
b. Call rainfall(year) and pass to it the value entered above.
c. Calculate the average based on the returned values from rainfall function.
d. Display the number of months, the total inches of rainfall, and the average rainfall per month for the entire period.

You are given an array of arrays a. Your task is to group the arrays a[i] by their mean values, so that arrays with equal mean values are in the same group, and arrays with different mean values are in different groups. Each group should contain a set of indices (i, j, etc), such that the corresponding arrays (a[i], a[j], etc) all have the same mean. Return the set of groups as an array of arrays, where the indices within each group are sorted in ascending order, and the groups are sorted in ascending order of their minimum element.

Example

For
a = [[3, 3, 4, 2],
[4, 4],
[4, 0, 3, 3],
[2, 3],
[3, 3, 3]]
the output should be

meanGroups(a) = [[0, 4],

[1],

[2, 3]]

mean(a[0]) = (3 + 3 + 4 + 2) / 4 = 3;
mean(a[1]) = (4 + 4) / 2 = 4;
mean(a[2]) = (4 + 0 + 3 + 3) / 4 = 2.5;
mean(a[3]) = (2 + 3) / 2 = 2.5;
mean(a[4]) = (3 + 3 + 3) / 3 = 3.
There are three groups of means: those with mean 2.5, 3, and 4. And they form the following groups:

Arrays with indices 0and 4 form a group with mean 3;
Array with index 1 forms a group with mean 4;
Arrays with indices 2and 3 form a group with mean 2.5.
Note that neither

meanGroups(a) = [[0, 4],

[2, 3],

[1]]

nor

meanGroups(a) = [[0, 4],

[1],

[3, 2]]

will be considered as a correct answer:

In the first case, the minimal element in the array at index 2 is 1, and it is less then the minimal element in the array at index 1, which is 2.
In the second case, the array at index 2 is not sorted in ascending order.
For
a = [[-5, 2, 3],
[0, 0],
[0],
[-100, 100]]
the output should be

meanGroups(a) = [[0, 1, 2, 3]]

The mean values of all of the arrays are 0, so all of them are in the same group.

Input/Output

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

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex:
101
133
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.

Code:

#include
#include // Enables use of rand()
#include // Enables use of time()
using namespace std;

int main() {
int seedVal = 0;

seedVal = 4;
srand(seedVal);

/* Your solution goes here */

return 0;
}

EXTRA CREDIT - 1 point! Scenario: A small business has implemented the best way to handle the few Service Accounts they have in their AD: They use a random password generator to set Service Account passwords, have 1 Service Account per service, and policies are set so that the accounts do not expire. The current passwords are not even stored anywhere. The company rigorously documents this setup, and diligently deprovisions accounts when services configurations change. The company has also implemented Account Monitoring, and know when any of the Service Accounts is being attempted to be used without the correct password, indicating an attack attempt. Due to the security sensitivity of the data accessible via the Service Accounts, any attack attempts will cause the service account to be disabled and IT staff alerted. Finally, the company has implemented a script that can be used to update the existing passwords -- resetting them via the only account delegated this authority: the Enterprise Root account. To ensure none of the IT staff can use the Enterprise Root account to reset a Service Account without consent, the password for the Enterprise Root account is only known to the company's CIO (Chief Information Officer), and is not stored anywhere. Identify (1) one major problem that you can see with this setup, and describe why this is a problem. There are multiple correct answers possible for this EXTRA CREDIT question.

In the QuickSort algorithm, the partition method we developed in class chose the start position for the pivot. We saw that this leads to worst case performance, O(n2), when the list is initially sorted. Try to improve your QuickSort by choosing the value at the middle, instead of the value at the start, for the pivot. Test your solution with the Driver you used for homework. Upload the output produced by the Driver, and your modified QuickSort source file.
