Which of the following statements is TRUE of a peer-to-peer network?
A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.
B. In a peer-to-peer network, all files being shared are kept on one server. Anyone who wants to access one of those files can get it directly from the server.
C. A peer-to-peer network can create heavy traffic and makes download times increase significantly.
D. Creating a directory of which computers have certain files is an acceptable practice.

Answers

Answer:

A. Different parties have very different opinions on what can and can’t be shared through a peer-to-peer network.

Explanation:
CORRECT
Choice 'A' is very true.
There have been many arguments and court cases over what content can and cannot be shared through a peer-to-peer network. Users of these networks often argue that free speech allows us to share whatever we want online. Content creators on the other hand frequently sue for copyright infringement.


INCORRECT
Choice 'B' is describing a centralized system, not a peer-to-peer network. In a peer-to-peer network, there is no central location of files. Files are transferred directly from one computer to another without a middleman.

Choice 'C' is also not true of peer-to-peer networks. These networks are actually much more efficient than centralized systems because there is no large server holding all the files. It takes less time to download files from a peer-to-peer network because there is no centralized source of information and files.

Choice 'D' is also false; this was decided in the court case about Napster, one of the first large peer-to-peer networks. Having a centralized directory of who has which files is not considered free speech.

The peer-to-peer network is said to have varying views that form the basis of what can and cannot be shared. Thus, option A is correct.

What is a peer-to-peer network?

A peer-to-peer network is given as the connection of the computers that are linked with the following same responsibilities and permissions.

The network is said to have varying views. Many debates and court cases have erupted over what content can and cannot be shared over a peer-to-peer network.

Users of these sites frequently argue that freedom of speech allows us to share whatever we want on the internet.On the other hand, content creators frequently file copyright infringement lawsuits.

Thus, option A is correct.

b. StudentIDs newStudent = new StudentIDs (Integer iVal1, Integer iVal2);
c. StudentIDs newStudent = new StudentIDs(int iVal1, int iVal2);
d. StudentIDs newStudent = new StudentIDs(9, 5);

Answers

Answer:

StudentIDs<TheType> newStudent = new StudentIDs<TheType>(9,5);

Explanation:

Required

Which statement creates a studentIDs object

The question has conflicting details as none of the options is true because some definitions that do not appear in the options.

So, I will answer the question based on the definition in the question.

From the question, we have the class definition to be:

public class StudentIDs<TheType extends Comparable<TheType>>

The above definition is a simple generic java class that follows:

public class Class-Name<Variable-name extends Comparable<Variable-name>>

The object of the class will be created using the following syntax:

Class-Name<TheType> Object-Name = new Class-Name<TheType>();

By comparison:

Class-Name = StudentIDs

Variable-name = TheType

So, the object will be defined as:

StudentIDs<TheType> newStudent = new StudentIDs<TheType>();

Solving further:

The class declares two variables (i1 and i2) as follows:

public StudentIDs(TheType i1, TheType i2)

This means that two TheType variables and/or values will be passed along with the definition of the class.

So, the object definition will be:

StudentIDs<TheType> newStudent = new StudentIDs<TheType>(9,5);

Walt needs to ensure that messages from colleague in another organization are never incorrectly identified as spam. What should he do?
- configure a safe recipient
- configure a blocked sender
- configure a safe sender
- do nothing

Answers

Answer:

Configure a safe sender.

Explanation:

Spam is a computer term that designates unwanted messages in an email, as well as advertising messages on websites. The main characteristic of these messages is that they do not respond to any previous action on the part of the receiver, such as a conversation with the sender or an advertisement that arises from search engine algorithms, but is sent randomly by an anonymous sender with objectives that are not entirely clear or legitimate.

Therefore, if Walt wishes that his colleague's messages are not classified as spam, he must categorize this person as a safe sender within his email box.

Using recursion, write a program that asks a user to enter the starting coordinates (row, then column), the ending coordinates (row then column), and calculates the number of paths from the starting coordinate to the ending coordinate.

Answers

Answer:

The program in Python is as follows

def Paths(row,col):

if row ==0 or col==0:

 return 1

return (Paths(row-1, col) + Paths(row, col-1))

row = int(input("Row: "))

col = int(input("Column: "))

print("Paths: ", Paths(row,col))

Explanation:

This defines the function

def Paths(row,col):

If row or column is 0, the function returns 1

if row ==0 or col==0:

 return 1

This calls the function recursively, as long as row and col are greater than 1

return (Paths(row-1, col) + Paths(row, col-1))

The main begins here

This prompts the user for rows

row = int(input("Row: "))

This prompts the user for columns

col = int(input("Column: "))

This calls the Paths function and prints the number of paths

print("Paths: ", Paths(row,col))

Write a program that prompts the user to enter an oligonucleotide sequence, such as TATGAGCCCGTA.

If the user entered a valid oligo sequence consisting only of the characters A, C, G, or T, the program should then display the reverse complement of that sequence, in this case TACGGGCTCATA, along with text indicating that it is the reverse complement .

After displaying the reverse complement, the program should then prompt the user to enter another sequence. The program should continue this pattern of prompting the user for a new oligo sequence and displaying its reverse complement until the user enters a sequence with at least one character that is invalid (i.e. a character other than A, C, G, or T).

Answers

Answer:

Explanation:

The following code is written in Python. It continues looping and asking the user for an oligonucleotide sequence and as long as it is valid it outputs the reverse complement of the sequence. Otherwise it exits the loop

letters = {'A', 'C', 'G', 'T'}

reloop = True

while reloop:

   sequence = input("Enter oligonucleotide sequence: ")

   for x in sequence:

       if x not in letters:

           reloop = False;

           break

   if reloop == False:

       break

   newSequence = ""

   for x in sequence:

       if x == 'A':

           newSequence += 'T'

       elif x == 'T':

           newSequence += 'A'

       elif x == 'C':

           newSequence += 'G'

       elif x == 'G':

           newSequence += 'C'

   print("Reverse Complement: " + newSequence)

What is the definition of personality? Your talents and skills The way you prefer to think and act The things that make you unique The jobs at which you will be good

Answers

Answer:

The things that make you unique.

Explanation:

Personality can be defined as a unique blend of various characteristics or traits such as mental, physical, emotional and social with respect to an individual.

Some of the factors that influence the personality of a person includes the following;

I. Hereditary.

II. Environment.

III. Culture.

IV. Family background.

Hence, the definition of personality would be the things that make an individual or a person unique.

This ultimately implies that, a person's personality is unique to him or her and as such differentiates them entirely from another person based on thought, emotional and behavioral patterns.

__' the low level language? a.machine and assembly c.3G and 4G d.machine and 4gl​

Answers

Answer:

a. machine and assembly.

Explanation:

An instruction set architecture (ISA) can be defined as series of native memory architecture, instructions, addressing modes, external input and output devices, virtual memory, and interrupts that are meant to be executed by the directly.

Basically, this set of native data type specifies a well-defined interface for the development of the hardware and the software platform to run it.

A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.

Machine and assembly are referred to as the low level programming language used in writing software programs or applications with respect to computer hardware and architecture. Machine language is generally written in 0s and 1s, and as such are cryptic in nature, making them unreadable by humans. Also, assembly language use commands written in English such as SUB, MOV, ADD, etc.

On the other hand, a high level language can be defined as a programming language which is generally less complex than a machine (low level) language and easy to understand by the end users (programmers).

This ultimately implies that, a high level programming language is typically a user friendly language and as such simplifies coding or programming for beginners.

Some examples of high level programming language are Python, Java, C#, Ruby, Perl, Visual Basic, PHP, Cobol, C++, Fortran, Javascript, etc.

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in the string. The output should include the input character and use the plural form, n's, if the number of times the characters appears is not exactly 1. g

Answers

Answer:

The program in Python is as follows:

string = input("String: ")

chr = input("Character: ")[0]

total_count = string.count(chr)

print(total_count,end=" ")

if total_count > 1:

   print(chr+"'s")

else:

   print(chr)

Explanation:

This gets the string from the user

string = input("String: ")

This gets the character from the user

chr = input("Character: ")[0]

This counts the occurrence of the character in the string

total_count = string.count(chr)

This prints the total count of characters

print(total_count,end=" ")

If the count is greater than 1

if total_count > 1:

Then it prints a plural form

   print(chr+"'s")

If otherwise

else:

Then it prints a singular form

Write a program that randomly (using the random number generator) picks gift card winners from a list of customers (every customer has a numeric ID) who completed a survey. After the winning numbers are picked, customers can check if they are one of the gift card winners. In your main function, declare an integer array of size 10 to hold the winning customer IDs (10 winners are picked). Pass the array or other variables as needed to the functions you write. For each step below, decide what arguments need to be passed to the function. Then add a function prototype before the main function, a function call in the main function and the function definition after the main function.

Answers

Answer:

Explanation:

Since no customer ID information was provided, after a quick online search I found a similar problem which indicates that the ID's are three digit numbers between 100 and 999. Therefore, the Java code I created randomly selects 10 three digit numbers IDs and places them in an array of winners which is later printed to the screen. I have created an interface, main method call, and method definition as requested. The picture attached below shows the output.

import java.util.Random;

interface generateWinner {

   public int[] winners();

}

class Brainly implements generateWinner{

   public static void main(String[] args) {

       Brainly brainly = new Brainly();

       int[] winners = brainly.winners();

       System.out.print("Winners: ");

       for (int x:winners) {

       int[] arr = new int[10];

       for (int x = 0; x < arr.length; x++) {
