If someone’s boss wanted to send a message to an employee that contains both a video and a Word processing document, which Internet service would be the most appropriate for her to use?\
Answer:
Email.
Explanation:
Email or electronic mail is a digital messaging platform that sends digitised data through the internet to a specific or group of specified receivers.
It uses the IMAP protocol to download copies of received data from the server to the client's computer and the POP protocol to store the data only on the server, with a copy sent to the client.
The email environment provides an attachment tool to add video, image or audio files to text documents on the message to be sent across.
A data file "parttolerance.dat" stores on one line, a part number, and the minimum and maximum values for the valid range that the part could weigh. Write a script "parttol" that will read these values from the file, prompt the user for a weight, and print whether or not that weight is within range. For example, IF the file stores the following:>> type parttolerance.dat123 44.205 44.287Here might be examples of executing the script:>> parttolEnter the part weight: 44.33The part 123 is not in range>> parttolEnter the part weight: 44.25The part 123 is within range
Final answer:
The script 'parttol' reads a data file with part numbers and weight tolerances, prompts for a weight input, and assesses if it's within range, providing feedback on part validity.
Explanation:
The question involves writing a script parttol for reading a data file named parttolerance.dat which contains part numbers and their respective weight tolerance ranges. The script should then prompt the user for a weight input and determine if that weight is within the range specified for a part number.
Here's a pseudocode outline for the parttol script:
Open and read the contents of parttolerance.dat.Extract the part number, minimum, and maximum weight values.Prompt the user to enter a weight.Check if the entered weight is within the range.Print a message indicating whether the part is within range.The execution of this script provides feedback to the user about the validity of the part's weight, thereby ensuring quality control in a manufacturing or engineering context.
___________ is the term used to describe the time taken from when a packet is sent to when the packet arrives at the destination. This is commonly referred to as "ping time" in various places such as online gaming.
Answer:
Packet delay
Explanation:
In measuring the efficiency of a network, one of the many factors to consider is packet delay. Packet delay is the total time taken for a data packet to travel from its source network to its destination. It is sometimes called latency.
High packet delay or latency are caused by, but not limited to, the following:
(i) The distance between the source network and the destination network
(ii) The size of the packet being transferred
(iii) The time taken to forward data - packet switching delay.

Answer:
The above query gives an error.
Explanation:
The query gives an error because is not the correct syntax of the select or inserts query.The syntax of the select query is as follows: "select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name;".The syntax of the insert query is : "insert into table_name (column_1_name, column_2_name,...,column_n_name) values (column_1_value, column_2_value,...,column_n_value);".The syntax of the insert and select query is : "insert into table_name (select Attributes_1_name, Attributes_2_name,...., Attributes_n_name from table_name);".But the above query does not satisfy any property which is defined above. Hence it gives a compile-time error.When information is modified by individuals not authorized to change it you have suffered a:_____a. Loss of confidentiality b. Loss of integrity c.

Do you believe that OOP should be phased out and we should start working on some alternative(s)? Provide your answer with Yes or No.
Give your opinion with two solid reasons to support your answer.
Answer:
I don't think so. In today's computer era, many different solution directions exist for any given problem. Where OOP used to be the doctrine of choice, now you would consider it only when the problem at hand fits an object-oriented solution.
Reason 1: When your problem can be decomposed in many different classes with each many instances, that expose complex interactions, then an OO modeling is justified. These problems typically produce messy results in other paradigms.
Reason 2: The use of OO design patterns provides a standardized approach to problems, making a solution understandable not only for the creator, but also for the maintainer of code. There are many OO design patterns.
What is it called to persist in trying to multitask can result in this; the scattering bits of one’s attention among a number of things at any given time?
Select one:
a. attention
b. multi tasking
c. continuous partial attention
d. none of the choices are correct
Answer: is Option B.
B). Multi tasking: A person capability to carry out more than one task at the same time is called multitasking. Person performing more than one task at the same time is nearly impossible and it's hard for him to focus on each and every detail, thus leading to scatter attention among numbers of things at a time resulting in inaccuracy and greater numbers of fault in final result.
Explanation of other points:
A). Attention: is defined as performing tasks with special care and concentration.
C). Continuous partial attention: Under this category people perform tasks by concentrating on different sources to fetch information by only considering the most valid information among all information. people who use this technique to gather information works superficially concentrating on the relevant information out of numerous sources in a short period of thinking process.
Database management systems are expected to handle binary relationships but not unary and ternary relationships.'
True or false
Answer:
False
Database management systems are expected to handle binary, unary and ternary relationships.
Explanation:
Unary Relationship: It is a recursive relationship which includes one entity in a relationship which means that there is a relationship between the instances of the same entity. Primary key and foreign key are both the same here. For example a Person is married to only one Person. In this example there is a one-to-one relationship between the same entity i.e. Person.
Binary Relationships: It is a relationship involving two different entities. These two entities identified using two relations and another relation to show relationship between two entities and this relation holds primary keys of both entities and its own primary key is the combination of primary keys of the both relations of the two entities. For example Many Students can read a Book and many Books can be obtained by a Student.
Ternary Relationships: is a relationship involving three entities and can have three tables. For example a Supplier can supply a specific Part of many Mobiles. Or many Suppliers may supply several Parts of many Mobile models.
Final answer:
The claim that database management systems cannot handle unary and ternary relationships is false; they can manage unary, binary, and ternary relationships as well as other complex relationships.
Explanation:
The statement 'Database management systems are expected to handle binary relationships but not unary and ternary relationships.' is false. Modern database management systems (DBMS) are equipped to handle a variety of relationship types, including unary (or recursive), binary, and ternary relationships, among others. A unary relationship is an association between two instances of the same entity. For example, an employee entity might have a manager relationship that relates an employee to another employee who is the manager. A binary relationship exists between two different entities, such as an 'Employee' entity and a 'Department' entity where an employee works in a department. A ternary relationship involves three different entities at the same time, such as a 'Supplier', 'Product', and 'Consumer' entities, where a supplier provides products to a consumer.
What is the value of vals[4][1]? double[][] vals = {{1.1, 1.3, 1.5}, {3.1, 3.3, 3.5}, {5.1, 5.3, 5.5}, {7.1, 7.3, 7.5}};
Answer:
When the user concludes the value of "vals[4][1]", then it will give an exception of "ArrayIndexOutOfBoundsException".
Explanation:
It is because the size of the above array is [4*3] which takes the starting index at [0][0] and ending index at [3][2]. It is because the array index value starts from 0 and ends in (s-1). When the double dimension array size is [5][5], then it will conclude the value of [4][1].The above array have following index which value can be calculated :-- [0][0],[0][1],[0][2],[1][0], [1][1],[1][2], [2][0], [2][1], [2][2],[3][0],[3][1] and [3][2].Which of the following is required for counter-controlled repetition?
A. a boolean
B. a method
C. a condition
D. All of the above
Counter-controlled repetition requires a condition to determine when the loop should stop, involving initializing a counter, setting a condition for it, and updating the counter within the loop. No boolean or method is strictly required, just the condition.
Explanation:The question asks which of the following is required for counter-controlled repetition. The correct answer is C. a condition. In computer programming, counter-controlled repetition requires a condition to determine when the repetition should stop. This involves initializing a counter to a starting value, setting a condition for the counter (such as counter < 10), and updating the counter within the loop (often incrementing or decrementing). This loop continues to execute as long as the condition evaluates to true.
For example, in a for loop, you might see something like for(int i = 0; i < 10; i++), where i is the counter, i < 10 is the condition that must be true for the loop to continue, and i++ updates the counter. No boolean or method is strictly required for this process, just the condition that guides the repetition.
The packets used to transmit voice on the Internet are similar to the packets that are used to send email. What are some of the advantages of this approach ?
Answer:
Quality of service (QOS).
Explanation:
In recent computer networking, the convergence of voice, video and text data packet has been made possible. There is no need for a dedicated network for a particular type of packet.
QOS or quality of set is a service rendered to voice or audio packets in VoIP phones to enhance communication.
The email is a digital mailing system that can be used to send all three packets. It enjoys the QOS as voice packets. It is given high preference for transmission and uses the TCP protocol to transmit data reliably.
CTIVITY 2.2.2: Method call in expression. Assign to maxSum the max of (numA, numB) PLUS the max of (numY, numZ). Use just one statement. Hint: Call findMax() twice in an expression.
Answer:
The one statement is:
maxSum = maxFinder.findMax(numA, numB) + maxFinder.findMax(numY, numZ);
Explanation:
The given code in the Activity contains a method named findMax() in class SumOfMax which has two parameters num1 and num2. The method returns the maximum value after comparing the values of num1 and num2.In the main() function, 4 variables numA, numB, numY and numZ of type double are declared and assigned the values numA=5.0, numB=10.0, numY=3.0 and numZ=7.0. Also a variable maxSum is declared and initialized by 0. After that an object named maxfinder of SumOfMax class is created using keyword new.SumOfMax maxFinder = new SumOfMax();
We can invoke the method findMax() by using reference operator (.) with the object name. So the task is to assign to maxSum the maximum of numA, numB plus maximum of numY, numZ in one statement. Using findMax() method we can find the maximum of numA and numB and also can find the maximum numY and numZ. The other requirement is add (PLUS) the maximum of numA, numB to maximum of numY, numZ. The statement used for this is given below:maxSum = maxFinder.findMax(numA, numB) + maxFinder.findMax(numY, numZ);
So as per the hint given in the question statement, findMax() function is being called twice, at first to find the maximum between the values of variables numA and numB and then to find the maximum between the values of numY and numZ. According to the given values of each of these variables:numA=5.0, numB=10.0,
So numB>numA
Hence findMax returns numB whose value is greater than numA Now findMax() is being called again for these variables:numY=3.0 and numZ=7.0
So numZ>numY as 7.0>3.0
Hence findMax() returns numZ whose value is 7.0Finally according to the statement maximum will be added and the result of this addition will be assigned to variable maxSum10.0 is added to 7.0 which makes 17.0 System.out.print("maxSum is: " + maxSum);This statement displays the value of maxSum which is 17.0
We will pass in 2 values, X and Y. You should calculate XY XY and output only the final result. You will probably know that XY XY can be calculated as X times itself Y times. # Get X and Y from the command line:import sysX= int(sys.argv[1])Y= int(sys.argv[2])# Your code goes here
Answer:
import sys
# The value of the second argument is assigned to X
x = int(sys.argv[1])
# The value of the third argument is assigned to Y
y = int(sys.argv[2])
# The result of multiplication of x and y is assigned to 'result'
result = x * y
#The value of the result is displayed to the user
print("The result of multiplying ", x, "and ", y, "is", result)
Explanation:
First we import sys which allow us to read the argument passed when running the program. The argument is number starting from index 0; the name of the python file been executed is sys.argv[0] which is the first argument. The second argument is sys.argv[1] and the third argument is sys.argv[2].
The attached file is named multplyxy (it wasn't saved as py file because the platform doesn't recognise py file); we can execute it by running: python3 multiplyxy.py 10 23
where x will be 10 and y will be 23.
To run the attached file; it content must be saved as a py file: multiplyxy.py
Which command would rename the file cows.txt to cheezburger.txt? Select one: a. mv cows.txt cheezburger.txt b. I can haz cheezburger! c. rename cows.txt d. rn cows.txt cheezburger.txt e. rm cows.txt
Answer:
Option A i.e., mv cows.txt cheezburger.txt is the correct option.
Explanation:
In Linux, mv means move that is used to move a file from one destination to other but the user also used the mv command for renaming the file because it is the easiest way to rename any file to others.
Syntax:
mv first_file.ext new_file.ext
In the above syntax, mv is the command and first_file is the name of that file whose name wants to be change and .ext is the file extension, new_file.ext is that file that name wants to be applied on first one.

The cardinality of a relationship is the maximum number of entity occurrences that can be involved in it. (T/F)
Answer:
False
Explanation:
In an entity relationship (ER) model, which is the conceptual illustration of certain entities and the relationships that exist between them, the cardinality of a relationship is the possible (minimum and maximum) number of entity occurrences that can be associated or involved in it.
Note: An entity is a real world object that is being modeled.
For example, a school has many staff members. The school and the staff members are the objects while the relationship between the school and the staff members is one-to-many.
One, many, zero are all values of cardinality.

Using basic programming (for loops, while loops, and if statements), write two MATLAB functions, both taking as input:
- dimension n;
- n x n matrix A;
- n x n matrix B;
-n × 1 vector x.
Have the first function compute ABx through (AB)x and the second compute ABx through A(Bx). Have both output:
- the number of flops used.
(a) Print out or write out the first function.
(b) Print out or write out the second function.

The correct code that corresponds to the question informed is attached in the photo and we can notice that the faster approach is A(Bx).
So knowing that the information given in the text is that;
For n = 100:
(AB)x: 10100 A(Bx): 200For n = 200:
(AB)x: 40200 A(Bx): 400For n = 400:
(AB)x: 160400 A(Bx): 800For n = 800:
(AB)x: 640800 A(Bx): 1600A(Bx) exist faster cause demand hardly any interplay to find a result: for (AB)x you bear (n*n)+n interplay while for A(Bx) you bear n+n, so we have that:
a)Watching the function for (AB)x:
function loopcount1 = FirstAB(A,B,x)
n = size(A)(1);
AB = zeros(n,n);
ABx = zeros(n,1);
loopcount1 = 0;
for i = 1:n
for j = 1:n
AB(i,j) = A(i,:)*B(:,j);
loopcount1 += 1;
end
end
for k = 1:n
ABx(k) = AB(k,:)*x;
loopcount1 += 1;
end
end
b) Watching the function for A(Bx):
function loopcount2 = FirstBx(A,B,x)
n = size(A)(1);
Bx = zeros(n,1);
ABx = zeros(n,1);
loopcount2 = 0;
for i = 1:n
Bx(i) = B(i,:)*x;
loopcount2 += 1;
end
for j = 1:n
ABx(j) = A(j,:)*Bx;
loopcount2 += 1;
end
end
