a __________ is a separate file from the user ids where hashed passwords are kept.
Answers
A password hash file is a separate file from the user IDs where hashed passwords are kept. This file stores the hashed versions of user passwords, providing an additional layer of security by ensuring that even if the file is accessed, the actual passwords remain encrypted and difficult to decipher.
A "password hash file" or a "password hash database" is a separate file or database where hashed passwords are stored. In this file, instead of storing passwords directly, the passwords are transformed into irreversible hash values using cryptographic algorithms such as bcrypt, PBKDF2, or SHA-256. Storing hashed passwords instead of plaintext passwords enhances security by making it extremely difficult for attackers to retrieve the original passwords from the hashes.

Answers
The first thing you should check if you discover that domain names are not resolving into IP addresses on a PC or workstation is the DNS server settings. DNS (Domain Name System) servers are responsible for resolving domain names into IP addresses, so if there is an issue with these settings, it can result in domain names not resolving into IP addresses.
To check the DNS server settings on a Windows PC, follow these steps:
Click the Windows Start button and select "Control Panel".Click "Network and Internet" and then "Network and Sharing Center".Click "Change adapter settings" on the left side of the window.Right-click on the network adapter you are using and select "Properties".Scroll down to "Internet Protocol Version 4 (TCP/IPv4)" and select it.Click the "Properties" button.Make sure that "Obtain DNS server address automatically" is selected.

Write a program to solve the problem using multiple processes where the first process spawns a fixed number of processes, say X, and the children spawn their own X multiple processes each, and so on and so forth. The maximum number of processes spawned should be NP. Your tree structure may be pre-defined and hence avoid using loops or recursion or counters to create a new tree. You also have the option to ask the user to provide X. At the end, you must produce at least 2 varying tree structures using X and compare with each other to address all questions.
Answers
The program described can be implemented using multiple processes and a pre-defined tree structure. By comparing different tree structures with varying values of X, we can address all questions related to performance and efficiency.
The problem described involves creating a program that uses multiple processes to spawn a tree structure with a maximum number of processes defined by NP. The first process spawns a fixed number of processes, X, and each of these children spawns their own X processes, and so on.
To implement this program, we can use the fork() system call to create new processes. The first process will call fork() X times to create X children processes. Each of these children processes will then call fork() X times again to create X more processes. This process will continue until we reach the maximum number of processes defined by NP.
To avoid using loops or recursion or counters to create a new tree, we can define the tree structure beforehand. We can represent the tree as a data structure, such as an array or a linked list, and use that structure to create the processes.
We can give the user the option to provide the value of X by accepting input from the command line or through a user interface.
To compare different tree structures, we can create two or more tree structures with different values of X and compare their performance. We can measure the time taken to create the tree structure, the total number of processes spawned, and the memory usage. We can also compare the efficiency of different tree structures in performing a particular task, such as searching for a specific value or sorting the nodes.

This code declares a class called "Employee" and defines two string variables called "first name" and "last name," as well as a double variable called "monthly salary."
What does a class's instance variable mean?A variable that is declared in a class but not within constructors, methods, or blocks is referred to as an instance variable. The instance variable can thus be given access modifiers. After the double variable called "monthly salary" in this code, the next step is to design a parameterized constructor that puts the value into the variable and checks the value of "monthly salary" using an if block. Additionally, it holds and returns its value via the getter and setter methods.

For iterating through a series, use a for loop. This functions more like an iterator method seen in other object-oriented programming languages and is less like the for keyword found in other programming languages.
How to write program in loop ?A high-level, all-purpose programming language is Python. Code readability is prioritised in its design philosophy, which makes heavy use of indentation. Python uses garbage collection and has dynamic typing. It supports a variety of programming paradigms, such as functional, object-oriented, and structured programming.
A while loop in Python is used to repeatedly run a block of statements up until a specified condition is met. And the line in the programme that follows the loop is run when the condition changes to false.
We can write the code in a simple way like this below :
n = int(input("How many numbers do you need to check? "))
divisible = 0

You are considering to invest in PFIZER. To that end, you download the stocks' historical price data given in "Computer_Exercise 2.xlsx". More precisely, you analyze the daily market-closing stock prices (or bid-ask averages in case of no trade on that day) from July 3,2000 to December 31, 2020. Please answer the following questions. 1. To start, you want to get an idea of the daily return that you could have obtained by buying on one trading day and selling on the next (assuming that there are no dividends). Compute the daily net return. Express the net return in terms of the percentage change in prices. 2. Now you want to know on how many of the total trading days in your sample you would have made a net return greater than or equal to 0.55%. What is the number of days on which your net return would have been above or equal 0.55% ? 3. You decided that you want to invest in PFIZER. Say that the outcome of your "experiment" (i.e. your investment) that you are interested in is whether you will win a net return larger than or equal to 0.55% on the first day or not. That is, you define a Bernoulli random variable, x, that can take on values 1 (net return >=0.55% on first day), and 0 (net return <0.55% on first day). Since you don't know how to otherwise approach the question (you are a first-time investor), you decide that the likelihood of successes in the past should be an indication of the future probability of success. Hence, what is the probability of success (i.e. net return >=0.55% ) based on the 2000-2020 sample? 4. What is the expected value/population mean of your Bernoulli variable X ? 5. What are the (population) variance and standard deviation of X ? Having computed the latter, comment on how good your "guess" for X (i.e. the expected value in 4.) really is. 6. Is the distribution of X symmetric about its mean? Why or why not? 7. Instead, now assume that your investment horizon is 14 trading days, where on each day you either can gain a net return larger than or equal to 0.55%(X 1
=1) or a net return <0.55%(X=0). Assume that the random variables X 6
i=1,2,…,14, are independent. The probability of success is still the same as in question 3 . above, and it is the same for all i. What is the probability that you will make a net return >=0.55% on 9 (out of the in total 14) following trading days? 8. Under the same assumptions as in question 7. above, what is the probability that you will make a net return above or equal 0.55% on more than 10 (out of the in total 14 ) following trading days?
Answers
1. The daily net return for investing in Pfizer is computed by calculating the percentage change in prices from one trading day to the next, assuming no dividends. This provides an idea of the daily return that could have been obtained by buying and selling the stock consecutively.
2. The number of trading days in the sample period where the net return would have been greater than or equal to 0.55% is determined to assess the frequency of favorable returns.
3. Based on the historical data, the probability of success, defined as obtaining a net return larger than or equal to 0.55% on the first day of investment, is determined by considering the likelihood of past successes as an indication of future success.
4. The expected value or population mean of the Bernoulli random variable X, representing the net return being larger than or equal to 0.55% on the first day, is calculated to determine the average outcome of the investment.
5. The population variance and standard deviation of X are computed to measure the variability and dispersion of the outcomes. This analysis provides insight into the reliability of the expected value.
6. The symmetry of the distribution of X about its mean is evaluated to understand whether the net return on the first day is equally likely to be above or below 0.55%. This impacts the overall risk assessment of the investment.
7. Assuming a 14-day investment horizon with independent random variables, the probability of achieving a net return greater than or equal to 0.55% on nine out of the 14 following trading days is calculated to assess the likelihood of sustained favorable returns.
8. Similarly, the probability of obtaining a net return above or equal to 0.55% on more than 10 out of the 14 following trading days is determined to gauge the probability of consistently positive returns within the specified investment period.
1. To calculate the daily net return, we need to compute the percentage change in prices using the historical stock prices data. This provides insights into the potential returns obtained by buying on one day and selling on the next, assuming no dividends.
2. By analyzing the net return values, we can determine the number of trading days where the net return exceeds or equals 0.55%. This helps understand the frequency of favorable returns during the sample period.
3. The probability of success is derived from the historical data, considering the past successes as an indication of the likelihood of future success. By calculating the proportion of days with a net return larger than or equal to 0.55% on the first day, we can estimate the probability.
4. The expected value or population mean of the Bernoulli variable X is calculated by summing the products of the possible outcomes (1 or 0) and their respective probabilities. This provides the average net return expected from the investment.
5. The population variance and standard deviation of X are computed to assess the spread or variability of the net return outcomes. By measuring the dispersion around the expected value, we can evaluate the consistency of the investment performance.
6. The symmetry of the distribution of X is assessed by examining whether the probabilities of net return being above or below 0.55% on the first day are equal. This provides insights into the potential biases or tendencies of the investment outcomes.
7. By assuming independent random variables X for each trading day, we can calculate the probability of obtaining a net return greater than or equal to 0.55% on nine out of the 14 following trading days. This evaluates the likelihood of sustained favorable returns within the specified investment period.
8. Similarly, we determine the probability of achieving a net return above or equal to 0.55% on more than 10 out of the 14 following trading days. This helps gauge the probability of consistently positive returns over the specified investment horizon.

6.36. Four kilograms of steam in a piston/cylinder device at 400kPa and 175 ∘
C undergoes a mechanically reversible, isothermal compression to a final pressure such that the steam is just saturated. Determine Q and W for the process.
Answers
To determine Q (heat transfer) and W (work) for the given process, we can use the first law of thermodynamics:
Q = ΔU + W
where ΔU is the change in internal energy of the system.
For an isothermal process, the change in internal energy (ΔU) is zero since the temperature remains constant. Therefore, the equation simplifies to:
Q = W
Now let's calculate the work done:
Work done (W) = P_initial * V_initial * ln(V_final / V_initial)
Given:
P_initial = 400 kPa
V_initial = (mass of steam) / (density of steam at initial conditions)
V_final = (mass of steam) / (density of saturated steam at final pressure)
To calculate the specific volume (V), we can use the steam tables or properties of water and steam at different conditions.
Once we have the specific volumes at initial and final conditions, we can calculate W using the equation mentioned above.
To calculate Q, we can use Q = W since it is an isothermal process.
