A: EFS is the security solution that would prevent a user from reading a file that they did not create.
The Encrypting File System (EFS) on Microsoft Windows is a property introduced in version 3.0 of NTFS that offers filesystem-level encryption. The EFS security solution enables files to be transparently encrypted in order to protect confidential data from cyber attackers with physical access to the computer. EFS encryption control technology enables users to have control over who can read the files on their system; thus EFS prevents provides prevention a file from reading by the user who did not create the file.

Finding outliers in a data set. Detecting unusual numbers or outliers in a data set is important in many disciplines, because the outliers identify interesting phenomena extreme events, or invalid experimental results. A simple method to check if a data value is an outlier is to see if the value is a significant number of standard deviations away from the mean of the data set. For example, X is an outlier if Xx - wxl > Nox where wx is the data set mean, ox is the data set standard deviation, and is the number of standard deviations deemed significant. Assign outlierData with all values in userData that are numberStd Devs standard deviations from userData's mean. Hint: use logical indexing to return the outlier data values. Ex: If userData is [9.50, 51, 49, 100 ) and numberStd Devs is 1, then outlierData is (9.100) Function Save C Reset D MATLAB Documentation 1 function outlierData = getOutliers(userData, numberStdDevs) 2 % getOutliers: Return all elements of input array data that are more than 3 % numStdDevs standard deviations away from the mean. 4 5 % Inputs: userData - array of input data values 6 % numberStdDevs - threshold number of standard deviations to determine whether a particular data value is an outlier * Outputs: outlierData - array of outlier data values Assign dataMean with the mean of userData dataMean = 0; Assign dataStdDev with userData's standard deviation dataStdDev = 0; % Assign outlierData with Return outliers outlierData = 0; 21 end Code to call your function C Reset 1 getOutliers (19, 50, 51, 49, 100, 1)
To assign outlierData with all values in userData that are numberStd Devs standard deviations from userData's mean, check the given code.
What is standard deviation?A statistic known as the standard deviation, which is calculated as the square root of variance, gauges a dataset's dispersion from its mean. By figuring out how far off from the mean each data point is, the standard deviation can be calculated as the square root of variance.
A higher deviation exists within a data set if the data points are further from the mean; consequently, the higher the standard deviation, the more dispersed the data.
//CODE//

Suppose TCP Tahoe is used (instead of TCP Reno), and assume that triple
duplicate ACKs are received at the 16th round. What are the ssthresh and the
congestion window size at the 19th round?
At the 16th round, when the triple duplicate ACKs are received, the ssthresh value is set to half of the current congestion window size.
This means that the ssthresh value at the 16th round is half of the congestion window size at the 16th round (i.e., W16). Thus, ssthresh at the 16th round = W16/2.
Congestion Window Size:
At the 19th round, the congestion window size is set to ssthresh + 3 × MSS, where MSS is the maximum segment size. Therefore, the congestion window size at the 19th round = ssthresh + 3 × MSS.
Thus, the ssthresh and the congestion window size at the 19th round can be calculated as follows:
ssthresh at the 19th round = W16/2
Congestion window size at the 19th round = (W16/2) + 3 × MSS

The correct response is b) sudo. The Linux command sudo, which stands for "super user do," enables the execution of programs as either the super user (also known as the root user) or another user.
Users must by default submit their own password for authentication, not the password of the target user, in contrast to the comparable command su. The system runs the requested command after authentication, if the configuration file (usually /etc/sudoers) grants the user access. The configuration file enables specific access rights, such as allowing commands only from the invoking terminal, needing a password per user or group, requiring a password to be entered each time, or never requiring a password at all for a given command line. Additionally, it can be set up to allow giving parameters or multiple instructions. The program sudo, which stands for superuser do or substitute user do, launches an elevated prompt without requiring you to assume a different identity. You can issue single commands as root or as another user, depending on the settings in the /etc/sudoers file.

The StudentAnswerSheet class is given and will be used as part of this system and contains a student's name and the student's answers for a multiple-choice test. Note the class attribute (key) and method (setKey) for the loading and storing the answer key. The answers are represented as "char" with an omitted answer being represented by the question mark '?'. These answers are stored in an array in which the position of the answer corresponds to the question number on the test (question numbers start at zero). A student's score on the test is computed by comparing the student's answers with the corresponding answers in the answer key for the test. One point is awarded for each correct answer and 1/4 point is deducted for each incorrect answer. Omitted answers do not change the student's score.
Write a class GradeStudents with a "main" method only that will read, using Scanner, a filename from the user (assumed to exist and in the correct format). Then read the comma-delimited input file containing the answer key in the first row and student names/answers in other rows, one per line.
First read and load the key. Then read, grade and output each student. Also determine the highest scoring student. If ties for highest scoring save all their names. You do not know how many questions are on the test until you read the first line of the file, which is always the key.

To write a class GradeStudents with a "main" method only that will read, using Scanner, a filename from the user (assumed to exist and in the correct format) check the code given below.
What is a filename?The title of a file and its extension are included in its filename. An entire file name is, for instance, "readme.txt."
Additionally, only the first part of a file may be described in the file name. A file with the name "readme" and the file name extension ".txt" is an example.

An ANOVA can find significant positive main effects at the same time as a significant negative interaction effect. True False
that is averaged over all other independent variable levels in experimental design and variance analysis.
Is it possible to have a large interaction but no major effect?
When the interaction is there, is it really required to include both main effects? No, you do not always require primary effects when there is an interaction, to put it simply. The interaction term won't, however, signify the same thing as it would if both primary impacts were taken into account.
What connection exists between interactions and major effects?
The impact one independent variable has on the dependent variable without taking into consideration other independent variables is known as a primary effect. The impact of one independent variable on another independent variable and how that impact affects the dependent variable is known as an interaction.

Which functions read from the keyboard or write to the monitor? Choose all correct answers. (Please be advised that there is penalty for incorrect answers) O stdin O stdout O print O fprintf O getchar O getc O putchar
In the question, some functions are used to read data from keyobard or write to monitor.
In the given question, different functions are given such as stdin, stdout, print, fprintf, getchar, putchar and getc either to read the data from keyboard or print/write to monitor.
The detail of each function are given below.
Functions that read data from keyboards are:getchar(): The getchar function read data from keyboard in form of characters.
getc(): it reads a single character from the current stream position and advances the stream position to the next character and it is identical to getchar() but it read one by one character.
However, stdin is not a function, but it is a class that provides methods to read the data such as getchar() and getc() etc.
Functions that print or write to monitor are:print(): this function print or write to monitor.
fprintf(): this function also print or write to monitor but in the formatted way.
putchar(): This function is used to print one charter to monitor or on the screen.
However, stdout is not a function, but it is a class that provides methods to print the data to screen such as print, fprint, putchar() etc.
