which of the following is the term used for a set of programs that acts as an interface between the applications that are running on a computer and the computer's hardware?
Answer:
Operating System
Explanation:
Operating System is a software program which acts as an mediator between computer hardware and user program applications and allows interaction between the user and computer/hardware. OS is used to manage both the hardware and software related tasks. OS is used to manage memory. It allocates memory to various processes and manages the primary memory by monitoring what portion of it is in use and what portion is not in usage.OS is used to manage processes by allocating and deallocating resources to processes which is also called process scheduling.It also provide security by preventing unauthorized access to data and computer. This is done via passwords which identify who is authorized to use a computer programs or manipulate data.Operating system also communicates with hardware devices via device drivers and also monitors the devices through I/O controller.OS allows communication between user and computer. User cannot understand computer language therefore assemblers, compilers, interpreters are provided by the OS to the user to interact with computer and computer programs.OS also controls and manages file system, it checks the status of the files, manages the directories and files and keeps information about where the data is stored.Which part of the Office interface is located across the top of the application window and organizes common features and commands into tabs.

What file system allows you to continue to add files to a CD or DVD disc after the initial burn, as long as there is room on the disc?
Answer:
Live file system
Explanation:
The live file system allows you to continue adding files to CD or DVD disc after an initial burn as long as there is enough space left on the disc.
In an attempt to burn files on a CD or DVD disc, Windows will prompt you if you want the live file system or the other (which is mastered disc format). Once you select the live file system, you can then keep adding files over and over until there is not enough space on the disc.
Note that Windows might not display the prompt as "live file system". It could be represented in some other ways like: "Like a USB flash drive". But then going through the prompt will tell you which is which.
Python provides a special version of a decision structure known as the ________ statement, which makes the logic of the nested decision structure simpler to write.
Answer:
if-elif-else
Explanation:
In Python if condition is used to decide whether a statement or a block of statements is to be executed or not based on the condition, if the condition evaluates to true then the block of statements is executed and if the condition is false then it is not executed.
Sometimes we need to execute some other statement when the condition is false. For example
if (number1 <= number2)
print (number1, "is the smallest")
Lets suppose we want to print another statement if this condition evaluates to false. If the condition gets false then the following message should be displayed:
print(number 2, "is the smallest")
For this purpose else statement is used along with if statement to execute the block of code when the if condition evaluates to false.
if (number1 <= number2)
print (number1, "is the smallest")
else:
print(number 2, "is the smallest")
Now what if there are three numbers or more numbers to be compared in order to identify the smallest number from the given numbers. So in this case we have multiple options to be checked. else statement will not be enough a for else there can be at most one statement. With if elif else multiple conditions can be checked and if any of the condition evaluates to true then its block of code is executed and if none of the condition is true then the last else statement will be executed.
For example:
if (number1 <= number2) and (number1 <= number3):
print (number1, "is the smallest")
elif (number2 <= number1) and (number2 <= number3):
print (number1, "is the smallest")
else:
print (number3, "is the smallest")
In this example number1 is compared to number2 and number3. If both numbers are less than number1 then the program control goes to elif statement where number2 is compared to number1 and number3. if this condition is false too then the final else part will be printed which is that number3 is the smallest.
Take another example where there are more number of expressions to be checked.
val = 50
if (val == 40):
print ("value is 40")
elif (val== 35):
print ("value is 35")
elif (val == 25):
print ("value is 25")
elif(val==15):
print ("value is 15")
else:
print ("value is not present")
This will output the else part value is not present, because none of the condition evaluates to true.
Final answer:
Python uses the 'elif' statement as a way to simplify nested decision structures, allowing programmers to add additional conditions without the need for excessive nesting.
Explanation:
Python provides a special version of a decision structure known as the elif statement, which makes the logic of the nested decision structure simpler to write. The elif statement stands for 'else if', and it allows for more succinct and readable conditional logic compared to using multiple if statements. For example:
if condition1:
# Code block for first condition
elif condition2:
# Code block for second condition
else:
# Code block if neither condition is met
Without elif, you would have to nest an if statement within an else block, which could make the code harder to read and understand.

An Update Request provides one-time Editor access. What feature could be used to allow information to be included in an update request, but restrict the recipient from making changes?
Answer:
The feature is the LOCK ROW FEATURE
Explanation:
There are basically about five to six different step in sending an update request which includes:
Activating or opening the sheet we want to update.
Highlight the row for which we want to request an update. We can decide to highlight multiple rows by using either the Shift or Ctrl direction command key
Click the down arrow in the second column of the row and choose Send Update Request. The Send Update Request dialogue box appears at this point
Then we follow the normal procedure of send a typical email by imputing the subject of mail and recipient then send.
It should be noted that an update request is sent to recipient(s) who will need to click the Update Rows button in the e-mail.
It should also be noted that the recipient’s browser shows a pared-down interface with only the rows you sent visible. The recipient can edit any unlocked rows so to make the recipient unable to edit or restrict recipient from making changes, we Lock the Row.
Something is wrong with the logic in the program above. For which values of time will the greeting "Good Morning!" be displayed? var time = promptNum("What hour is it (on a 24 hour clock)?"); var greeting = ""; if (time < 6) { greeting = "It is too early!"; } else if (time < 20) { greeting = "Good Day!"; } else if (time < 10) { greeting = "Good Morning!"; } else { greeting = "Good Evening!"; } console.log(greeting);
Answer:
There is logic problem in condition of elseif statement that is (time<20).
Explanation:
elseif(time<20) will be true for time<10 that means program will never greet good morning as to make logic correct either change condition from elseif(time<20) to elseif(time<20&& time>=10). Or change the order of condition like check first for elseif(time<10)
solution 1
if (time < 6) { greeting = "It is too early!"; }
else if (time < 20 && time>=10) { greeting = "Good Day!"; }
else if (time < 10) { greeting = "Good Morning!"; }
else { greeting = "Good Evening!"; }
console.log(greeting);
solution 2
if (time < 6) { greeting = "It is too early!"; }
else if (time < 10) { greeting = "Good Morning!"; }
else if (time < 20 ) { greeting = "Good Day!"; }
else { greeting = "Good Evening!"; }

An email can lead to miscommunication because:________.a. it is a faster mode of communicationb. there is no opportunity to interpret nonverbal cuesc. receiver might not have access to the Internetd. sender might type in the wrong email address
Answer:
b. there is no opportunity to interpret nonverbal cues
Explanation:
Email is a very efficient, quick and simple way for communication and it is being used a lot. With providing convenience and ease to the people to communicate and send messages to each other, email can also result in miscommunication. Miscommunication occurs when a person misinterprets the email messages sent by another. This is because its a non verbal way of communication. So the person might not be able to explicitly interpret the feelings , emotions or expressions of the sender of the email. So there is no way to understand meaning of some non verbal cues and can be perceived in a incorrect manner. Although various symbols can be used to express the feelings non verbally e.g. exclamation mark, capital letters, emoticons etc but even these symbols can be wrongly interpreted by the recipient as the use of some symbols like capital letter in email are not always appreciated . Even some simple messages can be perceived as sarcasm. So the major reason of the miscommunication caused by email is the absence of facial expressions, certain gestures and body language which are better interpreted with face to face communication.Answer:
The answer is B. An email can lead to miscommunication because there is no opportunity to interpret non-verbal cues. Everybody is different and we have different communication styles. To better communicate without having to have a negative tone on an email, the sender has to use positive positioning.

In data compression, there are many different methods for compressing data. We have many different protocols because there is no one method that provides the absolute best compression for all files in a reasonable amount of time. Which of the following is the BEST term for the above example?a) An algorithm b) A heuristic c) A selection d) An iteration
Answer:
A heuristic
Explanation:
Some time there are many methods to solve a particular problem, or learn something. These all methods are able to solve the problem. We cannot say that, which method is perfect or which one is optimal. These solutions are being used and sufficient to provide the solution. The technique that is used to solve problem in this way is called Heuristic.
For Example
There are many methods of teaching, few student understand some method and rest of the student better understand the other method of teaching. The students who think first method is perfect may think that other method is optimal and as well the students who think that second method is perfect, who may assume first solution as optimal.
The purpose of both of the teaching methods is to teach the students and both are sufficient to learn.

Which of the following statements is true?
1. Data and information are two terms that can be used interchangeably.
2. Information is data that has been organized.
3. Information is data that has been sifted.
4. Data is information that has been extracted.
Answer:
1. Data and information are two terms that can be used interchangeably.
Explanation:
Data is a raw fact, but information is a meaningful term.
Multiple data produce information
Data need to be processed toform information, information is understandable
The correct statement : Information is data that has been organized.
Hence correct statement is B .
Given, statements regarding data and information .
1. Data and information are two terms that can be used interchangeably.
This statement is not true.
While data and information are related, they are not the same thing. Data refers to raw facts, figures, or symbols that do not have any meaning on their own. On the other hand, information is the result of processing and organizing data in a meaningful way.
2. Information is data that has been organized.
This statement is true.
Information is created by organizing and processing data. When data is organized, categorized, or structured in a particular way, it becomes more meaningful and useful.
3. Information is data that has been sifted.
This statement is not entirely accurate.
While sifting or filtering data can be a part of the process of creating information, it is not the only step. Sifting implies removing unwanted or irrelevant data, which can help in narrowing down the focus, but it does not necessarily result in information.
4. Data is information that has been extracted.
This statement is not true.
Data is not the result of extracting information; rather, it is the raw material that is used to generate information. Data is collected, gathered, or obtained from various sources. It is then processed, organized, and analyzed to extract meaningful insights, which then become information.
Hence option B is correct .

What would you have to know about the pivot columns in an augmented matrix in order to know that the linear system is consistent and has a unique solution?
Answer:
The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.
[tex]rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)[/tex]
Then satisfying this theorem the system is consistent and has one single solution.
Explanation:
1) To answer that, you should have to know The Rouché-Capelli Theorem. This theorem establishes a connection between how a linear system behaves and the ranks of its coefficient matrix (A) and its counterpart the augmented matrix.
[tex]rank(A)=rank\left ( \left [ A|B \right ] \right )\:and\:n=rank(A)[/tex]
[tex]rank(A) <n[/tex]
Then the system is consistent and has a unique solution.
E.g.
[tex]\left\{\begin{matrix}x-3y-2z=6 \\ 2x-4y-3z=8 \\ -3x+6y+8z=-5 \end{matrix}\right.[/tex]
2) Writing it as Linear system
[tex]A=\begin{pmatrix}1 & -3 &-2 \\ 2& -4 &-3 \\ -3 &6 &8 \end{pmatrix}[/tex] [tex]B=\begin{pmatrix}6\\ 8\\ 5\end{pmatrix}[/tex]
[tex]rank(A) =\left(\begin{matrix}7 & 0 & 0 \\0 & 7 & 0 \\0 & 0 & 7\end{matrix}\right)=3[/tex]
3) The Rank (A) is 3 found through Gauss elimination
[tex](A|B)=\begin{pmatrix}1 & -3 &-2 &6 \\ 2& -4 &-3 &8 \\ -3&6 &8 &-5 \end{pmatrix}[/tex]
[tex]rank(A|B)=\left(\begin{matrix}1 & -3 & -2 \\0 & 2 & 1 \\0 & 0 & \frac{7}{2}\end{matrix}\right)=3[/tex]
4) The rank of (A|B) is also equal to 3, found through Gauss elimination:
So this linear system is consistent and has a unique solution.

A loop decision point for an algorithm consists of three features: an initial value, a set of actions to be performed, and a(n) ________.
a. class operator
b. documentation plan
c. test condition
Answer:
Option c is the correct answer for the above question.
Explanation:
A loop is used to repeat some lines in some specific times which depends on some conditions of the loop. If a person wants to print "welcome" on 5 times then he can do this by two ways one is writing a print statement 5 times and the other is states a loop that executes 5 times through condition. The loop is described or written by three necessary points which are:-
The fist is to initialize the initial value which tells the compiler for the starting point of the loop.The second is to any action for that condition variable which takes the loop for the direction of ending points.The third is a condition that defines the ending point of the loop.The above question also states about the loop in which first and second points are given then the third point is necessary to complete the sentence which is states in option c. Hence the option c is correct while the other is not because--
Option 'a' states about the class operator which is not the part of the loop. Option b states about the documentation plan which is also not the part of the loop.
