In older existing installations, where an equipment ground does not exist in a metal switch box that is located within reach of a conductive floor such as tile or cement, NEC 404.9(B) requires the use of what kind of faceplate
Answer:
A metal faceplate with grounding means
Explanation:
metal faceplate with grounding means is required in older existing installations, where an equipment ground does not exist in a metal switch box that is located within reach of a conductive floor such as tile or cement.
Answer:
The NEC requires the use of a metallic faceplate for this situation.
Explanation:
NEC 404.9(B) requires a metal faceplate having a means for grounding to be used in older installations where there is no ground for an equipment in a metal box switch located within a conductive floor. There is however an exception which states that as long as the wiring method does not have anything to do with an equipment-grounding conductor, it is required that a snap switch that is wired and located within reach of conductive floors must have a nonmetal faceplate or protected by an interrupter.

A technician removed the Trojan, but a security administrator expressed concern that unauthorized personnel might be able to access data on the server. The security administrator decided to check the server further. Of the following choices, what is the administrator MOST likely looking for on this server?
a. Trojan
b. spyware
c. adware
d. ransomware
Answer:
B. Spyware
Explanation:
Spywares are silent software that steals sensitive information such as internet or company data, and other similar information. They are oftentimes unnoticed and supply stolen data to external users, data centers or advertisement companies.
Sophisticated spyware can go as far as installing software to manipulate your settings or use passwords on your behalf.
Even though the Trojan was detected in our scenario, The Trojan would have created a backdoor to allow spyware in. This spyware will not be easily noticed by the technician or the antivirus, however, it could be more devastating than the Trojan.
That is why the security administration expresses concern over a breach despite the removal of the Trojan.

Suppose the beta of Microsoft is 1.13, the risk-free rate is 3 percent, and the market risk premium is 8 percent. Calculate the expected return for Microsoft.
Answer:
8.65%
Explanation:
Rj = Rf + risk premium.
Rj = Rf + β[E(RM − Rf)].
= 3 + 1.13 (8 - 3)
= 3 + 1.13 x 5
= 3 + 5.65
= 8.65 percent
This relationship between risk and expected return is called the security market line.
The expected return for Microsoft, using CAPM and the given risk-free rate, beta, and market risk premium, is 12.04 percent.
To calculate the expected return for Microsoft, given that the beta of Microsoft is 1.13, the risk-free rate is 3 percent, and the market risk premium is 8 percent, we can use the Capital Asset Pricing Model (CAPM). The CAPM formula is:
Expected Return = Risk-Free Rate + (Beta Times Market Risk Premium)
Plugging in the given values:
Expected Return = 3% + (1.13 Times 8%)
Expected Return = 3% + 9.04%
Expected Return = 12.04%%
Therefore, the expected return for Microsoft is 12.04% percent.
The __________ cipher is a single-alphabet substitution cipher that is a permutation of the Caesar cipher. All characters are rotated 13 characters through the alphabet.
Answer:
ROT13 is the correct answer of this question.
Explanation:
The ROT13 cipher is a single-alphabet substitution cipher, which is a Caesar cipher permutation. All letters are rotated through the alphabet to 13 characters. ROT13 is a particular case of the Caesar cypher that was created in ancient Rome.
ROT13 is a direct letter cryptographic hash function, combining a letter in the alphabet with the 13th letter after it. ROT13 is used from a casual viewpoint in online forums to cover surprises, punchlines, puzzle solutions and offensive content.Final answer:
The ROT13 cipher is a permutation of the Caesar cipher where each character in the plaintext is rotated 13 places through the alphabet; it's different from the transposition cipher used in the Zimmerman Telegram.
Explanation:
The cipher described in the student's question is the ROT13 cipher. This cipher is a specific type of substitution cipher where each letter in the plaintext is rotated 13 positions down the alphabet. For example, 'A' becomes 'N' and 'N' becomes 'A'. It is called a permutation of the Caesar cipher because, like the Caesar cipher, it involves shifting the alphabet. However, the shift is always 13, making it a fixed variation. Unlike a transposition cipher, such as the one used in the Zimmerman Telegram, a substitution cipher replaces one character with another rather than rearranging them.

A Color class has a constructor that accepts three integer parameters: red, green and blue components in the range of 0 ... 255 with 0 representing no contribution of the component and 255 being the most intense value for that component. The effect of full or semi-transparency can be achieved by adding another component to the color called an alpha channel. This value can also be defined to be in the range of 0...255 with 0 representing opaque or totally non-transparent, and 255 representing full transparency. Define a class AlphaChannelColor to be a subclass of the Color class. AlphaChannelColor should have the following: - an integer instance variable alpha - a constructor that accepts four parameters: red, green, blue and alpha values in that order. The first three should be passed up to the Color class' constructor, and the alpha value should be used to initialize the alpha instance variable. - a getter (accessor) method for the alpha instance variable
Answer:
The following are the code in the Java Programming Language.
//define a class and inherit the other class
public class AlphaChannelColor extends Color {
//define constructor and pass arguments
public AlphaChannelColor(int red, int green, int blue, int alpha) {
super(red, green, blue);
this.alpha = alpha;
}
//define function
public int getAlpha()
{
return alpha;
}
//declare a private type variable
private int alpha;
}
Explanation:
The following are description of the program.
Firstly, define a class 'AlphaChannelColor' that inherits the other class that is 'Color' through the extend keyword. Define the constructor (in Java, the class name and the name of the constructor remain same) and pass four integer data type arguments 'red', 'green', 'blue' and 'alpha' in its parameter. Define the integer data type function 'getAlpha()' that returns the value of the variable 'alpha'.An IT department submits a purchase order to buy a new computer from a vendor.

You are tasked with accumulating survey data on a web page and are responsible for it being free from dirty data once you close the survey and get the data to the researching team. Which is the best way to handle the possibility of dirty data?
Answer:
Build a website that validates data as the survey participant takes the survey.
Explanation:
Whenever a user is charged towards gathering survey information on such a webpage and seems to be liable for freeing this against bad data when the survey is closed as well as the data will be sent to the testing group.
Creating a platform that validates information is just the easiest approach to tackle the risk of bad results as when the research user completes the test.
The analysts at Techno Info Systems are considering the four-model approach to system development for a new client. If they make use of the four-model approach, which of the following is a likely outcome?
A. It will not be possible to get ac clear picture of the current system functions before modifications are made.
B. Time taken to develop the model increases.
C. The requirements of a new information system will always be different from the current information system.
D. Costs need to develop a logical and physical model of the current system will be less.
Answer:
Option B is correct.
Explanation:
Within Techno Info Systems the user has been analyst contemplating that four-model concept towards computer development for such its new customer. When they adopt that four-model method, thus the result seems to be the time taken to implement the rises in the method.
So, therefore the other options are incorrect according to the following scenario.
Final answer:
Using the four-model approach to system design likely leads to an increase in the time taken to develop the model, as it entails creating complex and detailed models to replace the real system for analysis.
Explanation:
If the analysts at Techno Info Systems employ the four-model approach to system development for a new client, a likely outcome is that time taken to develop the model increases. This approach involves creating different models, each with its purpose and complexity. For instance, understanding ecosystem dynamics necessitates analytical and simulation models that can predict the consequences of changes within an ecosystem. Similarly, a four-model approach in system development requires meticulous detail, and this extensive modeling aims to replace the real system with an easier-to-examine version, ultimately providing more reliable predictions and a detailed design.
However, as the complexity of models increases with the aim of better accuracy and understanding, it also often leads to longer development times. While the models serve to understand the system before making modifications, a more detailed four-model approach means investing more time to build and analyze each model. One must balance the drive for comprehensive understanding against the requirement to deliver results in a timely manner.

For the client server application over UDP, why may the client program be executed before the server program?
Answer:
In a TCP connection the server program must be executed before the client program because if the server is not listening, the client fails to establish connection with the server.
UDP does not require a connection from the server.
The server software must be run before the client program in a TCP connection because the client cannot connect to the server if the server is not listening. The server does not need to establish a connection for UDP.
What is client server application?In theory, a client/server application consists of client software that makes use of server software's services. The client contacts the server application's operations to request services from it.
A client frequently requests a server for goods or services rather than sharing any of its resources. Clients thereby establish channels of communication with servers, which subsequently keep an eye out for incoming requests. The client-server architecture is used by a number of computer programs, including email, network printing, and the World Wide Web.
A client application uses the framework provided by an underlying client to access the resources provided by WebSphere® Application Server.
Thus, The server software must be run before the client program in a TCP connection.
