Answer:
Java Socket programming is used for communication between the applications running on different JRE.
Java Socket programming can be connection-oriented or connection-less.
Socket and ServerSocket classes are used for connection-oriented socket programming and DatagramSocket and DatagramPacket classes are used for connection-less socket programming.
The client in socket programming must know two information:
IP Address of Server, and
Port number.
Here, we are going to make one-way client and server communication. In this application, client sends a message to the server, server reads the message and prints it. Here, two classes are being used: Socket and ServerSocket. The Socket class is used to communicate client and server. Through this class, we can read and write message. The ServerSocket class is used at server-side. The accept() method of ServerSocket class blocks the console until the client is connected. After the successful connection of client, it returns the instance of Socket at server-side.
Explanation:
Creating Client:
import java.io.*;
import java.net.*;
public class MyServer {
public static void main(String[] args){
try{
ServerSocket ss=new ServerSocket(6666);
Socket s=ss.accept();//establishes connection.
DataInputStream dis=new DataInputStream(s.getInputStream());

Consider a short, 90-meter link, over which a sender can transmit at a rate of 420 bits/sec in both directions. Suppose that packets containing data are 320,000 bits long, and packets containing only control (e.g. ACK or handshaking) are 240 bits long. Assume that N parallel connections each get 1/ N of the link bandwidth. Now consider the HTTP protocol, and assume that each downloaded object is 300 Kbit long, and the initial downloaded object contains 6 referenced objects from the same sender.
Required:
Would parallel download via parallel instances of non-persistent HTTP make sense in this case? Now consider persistent HTTP. Doyou expect significant gains over the non-persistent case?

Each union variable should be printed as a float, a double and a long double. Do the values always print correcly? Note The long double result will vary depending on the system (Windows, Linux, MAC) you use. So do not be concern if you are not getting the correct answer.

Write a program that creates an an array large enough to hold 200 test scores between 55 and 99. Use a Random Number to populate the array.Then do the following:1) Sort scores in ascending order.2) List your scores in rows of ten(10) values.3) Calculate the Mean for the distribution.4) Calculate the Variance for the distribution.5) Calculate the Median for the distribution.
Answer:
Explanation:
The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.
from random import randint
import numpy as np
test_scores = []
for x in range(200):
test_scores.append(randint(55, 99))
sorted_test_scores = sorted(test_scores)
count = 0
print("Scores in Rows of 10: ", end="\n")
for score in sorted_test_scores:
if count < 10:
print(str(score), end= " ")
count += 1
else:
print('\n' + str(score), end= " ")
count = 1
mean = np.mean(sorted_test_scores)
variance = np.var(sorted_test_scores, dtype = np.float64)
median = np.median(sorted_test_scores)
print("\n")
print("Mean: " + str(mean), end="\n")
print("Variance: " + str(variance), end="\n")
print("Median: " + str(median), end="\n")
Which of the following acronyms refers to a network or host based monitoring system designed to automatically alert administrators of known or suspected unauthorized activity?
A. IDS
B. AES
C. TPM
D. EFS
Answer:
Option A (IDS) is the correct choice.
Explanation:
Whenever questionable or unusual behavior seems to be detected, another alarm is sent out by network security equipment, which would be considered as Intrusion Detection System.SOC analysts as well as occurrence responders can address the nature but instead, develop a plan or take steps that are necessary to resolve it predicated on such notifications.All other three alternatives are not related to the given query.

Answer:
The advantage of returning a structure type from a function when compared to returning a fundamental type is that
e. a and b only.
Explanation:
One advantage of returning a structure type from a function vis-a-vis returning a fundamental type is that the function can return multiple values. The second advantage is that the function can return can an object. This implies that a function in a structure type can be passed from one function to another.

Create a Python dictionary that returns a list of values for each key. The key can be whatever type you want.
Design the dictionary so that it could be useful for something meaningful to you. Create at least three different items in it. Invent the dictionary yourself. Do not copy the design or items from some other source.
Next consider the invert_dict function.
def invert_dict(d):
inverse = dict()
for key in d:
val = d[key]
if val not in inverse:
inverse[val] = [key]
else:
inverse[val].append(key)
return inverse
Modify this function so that it can invert your dictionary. In particular, the function will need to turn each of the list items into separate keys in the inverted dictionary.
Run your modified invert_dict function on your dictionary. Print the original dictionary and the inverted one.
Describe what is useful about your dictionary. Then describe whether the inverted dictionary is useful or meaningful, and why.

Answer:
ITS A SIMPLE ANSWER BUT THE PROBLEM IS TOO BIG!
Explanation:
The phishing email might contain a link which on clicking will take you to a fake web page. For example, the link might take you to a fake bank website which looks very legitimate but in reality is just a lookalike. If the victim falls for the scam and enters his/her account details on the website, the details will actually go to the hacker's server instead of going to the bank and the hacker will have all the information that the victim has provided on the website.
