Answer:
logical data structures are impossible in data flow diagram
A black hole is logically impossible in a data flow diagram (DFD) because a process must act on input, shown by an incoming data flow, and produce output, represented by an outgoing data flow.
What is a data flow diagram?A data flow diagram (DFD) is a graphical or visual representation of a business's activities through data movement that employs a defined set of symbols and notations. They are frequently components of formal methodologies like Structured Systems Analysis and Design Method (SSADM). DFDs may appear to be flow charts or Unified Modeling Language (UML) diagrams on the surface, but they are not intended to depict specifics of program logic.
In a data flow diagram (DFD), a black hole is theoretically impossible since a process must act on input, represented by an entering data flow, and create output, represented by an existing data flow.
Thus, the required fill-in-the-blank would be a black hole in the given sentence.

You manage small LAN for a branch office. The branch office has three file servers and few client workstations. You want to use Ethernet device and offer guaranteed bandwidth to each server. You design the network by connecting all network devices to a switch. Connect each server to its own switch port.
Explanation:
A local-area network (LAN) is a computer network that spans a relatively small area.Most often, a LAN is confined to a single room, building or group of buildings, however, one LAN can be connected to other LANs over any distance via telephone lines and radio waves.The LAN is the networking infrastructure that provides access to network communication services and resources for end users and devices spread over a single floor or building.Designing a LAN for the campus use case is not a one-design-fits-all proposition. If there is a single 48-port switch, 47 devices can be supported, with only one port used to connect the switch to the rest of the network, and only one power outlet needed to accommodate the single switch
A server is expected to process 2,000 transactions per second during its initial year of deployment. If it is expected to increase transaction growth by 10% annually, how many transactions per second should the server be able to process by the end of its fifth year?
Answer:
This is like a compound interest problem,
Here, p=2000
r=10%
t=5
Transaction after 5 years= 2000(1+10/100)^5= 3221.02 per second
Explanation:
This is as explained above a compound interest type of question. And the number of transaction per second after 5 years is equal to 3221. Remember, you need to understand the difference between compound interest and simple interest. In first one, we have new p after each year. However, in Simple interest, the p remains the same as the first one.
The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word ____________________, followed by the name of the column to be updated, an equals sign, and the new value.
The format for the UPDATE command is the word UPDATE, followed by the name of the table to be updated. The next portion of the command consists of the word SET, followed by the name of the column to be updated, an equals sign, and the new value.
Explanation:
An Update Query is an action query (SQL statement) that changes a set of records according to criteria you specify.The SQL UPDATE Query is used to modify the existing records in a table. You can use the WHERE clause with the UPDATE query to update the selected rows, otherwise all the rows would be affected. Update Queries let you modify the values of a field or fields in a table.UPDATE Syntax
UPDATE table_name SET column1 = value1, column2 = value2, ... WHERE condition;UPDATE table_name SET column1 = value1, column2 = value2, etc WHERE condition;
table_name: name of the table column1: name of first , second, third column.... value1: new value for first, second, third column.... condition: condition to select the rows for which the values of columns needs to be updated.Assume there is a variable, nobel_peace_prizes, that is associated with a dictionary that maps years to winners of the Nobel Peace Prize for that year and assume it is up-to-date through the year 2005. Write a statement that adds an entry that maps the key 2006 to "Muhammad Yunus and Grameen Bank".
Final answer:
To add Muhammad Yunus and Grameen Bank as the 2006 Nobel Peace Prize winners, add the entry 'nobel_peace_prizes[2006] = "Muhammad Yunus and Grameen Bank"' to the dictionary.
Explanation:
To add an entry that maps the key 2006 to "Muhammad Yunus and Grameen Bank" to the nobel_peace_prizes dictionary, you would use the following Python statement:
nobel_peace_prizes[2006] = "Muhammad Yunus and Grameen Bank"
This statement will append a new key-value pair to the dictionary, where the key is 2006 and the value is 'Muhammad Yunus and Grameen Bank'. This assumes that nobel_peace_prizes is a dictionary that is already defined and associated with the Nobel Peace Prize winners up until the year 2005. By executing this statement, the dictionary gets updated with the Nobel Peace Prize winner for the year 2006.

Explanation:
An array of integers named parkingTickets has been declared and initialized to the number of parking tickets given out by the city police each day since the beginning of the current year. (Thus, the first element of the array contains the number of tickets given on January 1; the last element contains the number of tickets given today.) A variable named ndays has been declared and initialized to hold the size of the array. (Thus, if today were January 18, ndays would have the value 18; if today were February 3, ndays would have the value 34.) In addition, a variable named mostTickets has been declared, along with a variable k. Without using any additional variables, and without changing the values of ndays or the elements of the parkingTickets array, write some code that results in mostTickets containing the largest value found in parkingTickets.
An array of integers named parkingTickets has been declared and initialized to the number of parking tickets given out by the city police each day since the beginning of the current year.
Explanation:
A variable named ndays has been declared and initialized to hold the size of the array.The first element of the array contains the number of tickets given on January 1; the last element contains the number of tickets given today.A variable named mostTickets has been declared, along with a variable k.If today were January 18, ndays would have the value 18; if today were February 3, ndays would have the value 34mostTickets=0;
for (k=0; k< ndays; k++)
{
if (parkingTickets[k]>mostTickets) mostTickets=parkingTickets[k];
}
To find the largest value in the parkingTickets array without using any additional variables or changing the values of ndays or the elements in the array, you can use a for loop to iterate through the elements of the array.
Explanation:To find the largest value in the parkingTickets array without using any additional variables or changing the values of ndays or the elements in the array, you can use the following code:
for (int i = 1; i < ndays; i++) {
if (parkingTickets[i] > parkingTickets[i - 1]) {
mostTickets = parkingTickets[i];
}
}
This code iterates through the elements of the array and checks if each element is greater than the previous element. If it is, it updates the value of mostTickets to the current element. At the end of the loop, mostTickets will contain the largest value found in parkingTickets.

"The graphics driver was recently updated on a system. Now, the graphical user interface (GUI) is not displaying, preventing the user from logging in. You need to access the system locally. Which of the following commands will access the tty2 terminal?"
You can access a full-screen TTY session by holding down the Ctrl+Alt keys, and pressing one of the function keys. Ctrl+Alt+F3 will bring up the login prompt of tty3. If you log in and issue the tty command, you'll see you are connected to /dev/tty3.
Explanation:
tty2 is short for teletype, but it's more popularly known as terminal. It's basically a device (implemented in software nowadays) that allows you to interact with the system by passing on the data (you input) to the system, and displaying the output produced by the systemYou can either : press ctrl+alt+F7 Or run the command startx if the above commands do not work.The tty command of terminal basically prints the file name of the terminal connected to standard input.In Linux, there is a pseudo-teletype multiplexor which handles the connections from all of the terminal window pseudo-teletypes (PTS). The multiplexor is the master, and the PTS are the slaves. The multiplexor is addressed by the kernel through the device file located at /dev/ptmx.The -s (silent) option causes tty to generate no output.
Final answer:
Access tty2 terminal by pressing Ctrl+Alt+F2, log in with your username and password, and be aware that password characters won't display for security reasons.
Explanation:
To access the tty2 terminal on a Linux system when the GUI is not displaying, you can use the keyboard shortcut Ctrl+Alt+F2. This will switch you from the GUI to the second tty terminal, tty2. Once the terminal is accessed, you will be prompted to log in with your username and password. Remember that when typing your password, you will not see any characters on the screen; this is a security feature to prevent onlookers from seeing the contents or length of your password. After successfully logging in, the command prompt should reflect your username, similar to oneils atmosphere ~$, indicating you are now logged in to the system via the command-line interface.
What will be displayed after the following code executes? (Note: the order of the display of entries in a dictionary are not in a specific order.) cities = {'GA' : 'Atlanta', 'NY' : 'Albany', 'CA' : 'San Diego'} if 'FL' in cities: del cities['FL'] cities['FL'] = 'Tallahassee' print(cities)
Answer:
Nothing will be printed
Explanation:
You can easily find out that FL is not a member of the Dictionary. And we are checking these in the if. Since the if condition ends up being false, the further process will not run as they will only if the condition ends up being true. Hence, nothing will be printed.
Remember, del is used to delete a dictionary item. If this would have been a true condition for if then the FL item in the dictionary would have been deleted as it, in that case, would have been present there. And then the next line would have again added the FL item, and print would have printed the dictionary items with FL item as well. However, since if the condition is ending up being false, nothing will be printed.
If cities['FL'] and print is outside if then
the output will be
{'FL': 'Tallahassee', 'GA': 'Atlanta', 'NY': 'Albany', 'CA': 'San Diego'}
Final answer:
The Python code checks for the 'FL' key in the cities dictionary, does not find it, and thus the dictionary remains unchanged when printed.
Explanation:
The question relates to the execution of a Python code snippet involving a dictionary named cities. Upon running the provided code, the following will be displayed: { 'GA' : 'Atlanta', 'NY' : 'Albany', 'CA' : 'San Diego' }. The code first checks if 'FL' is a key in the cities dictionary, which it is not. Therefore, the deletion operation is not performed and the subsequent assignment of 'FL' to 'Tallahassee' is also not executed. As a result, the initial contents of the dictionary remain unchanged before it is printed.
An experimenter discovers that the time for people to detect a string of letters on a computer screen is 400 milliseconds, and that the time to push one of two buttons as to whether that string of letters is a legitimate word (e.g., travel) versus a nonword (e.g., terhil) is 575 milliseconds. Which technique would be most useful in figuring out the time for word recognition, independent of letter-string detection?
a. Introspectionsb. Operant conditioningc. Neuropyshologyd. Subtractive method
Answer:
The correct answer to the following question will be Option D (Subtractive method ).
Explanation:
This approach essentially requests a participant to construct two activities that are already in almost every way similar, except for a mental process that is assumed to also be included in any of the activities although omitted in another.This method will be much more valuable when deciding the period for phonemic awareness, despite text-string identification.The other three options are not related to the given scenario. So that Option D is the right answer.

Students in a 6th grade science class are completing a project about an invention for which they must print a 3-D prototype on the 3-D printer. After giving them instruction about the 3-D printer software, some of the students are still struggling with how to use the software to create the prototype they envision.
What is the best way to help the students complete the assignment?
Answer:
Providing them with a template and simple instructions for how to design and print their prototype.
Explanation:
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
The creation of a 3D printed object is achieved using additive processes. In an additive process an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.
By providing them with the information for how to design the 3D printer and how to print heir prototype in a template is best way to help the students.
It will need some prior research about 3D Printer.

Port Replicator
Docking Station
Answer:
A Port Replicator
Explanation:
Port Replicators are universal and do not require that your computer (laptop) be docked (Placed) on them to function. All you need is the devices connected to the port replicator and whenever you need to move the laptop, you disconnect the port replicator from it. It generally is connected via a type of USB port.
A Docking station on the other hand can be a drag in the sense that you might have a challenge always having to dock and undock your laptop from the station anytime you need to move. This can be annoying if you are in a rush. Also the Docking stations use expansion ports which are a lot of times not universal (Not just any type of laptop can connect to the dock stations, just your model or specified models).
Answer:
Port Replicator
Explanation:
While you may be able to use a docking station for this purpose, a port replicator is designed specifically for this kind of use.

What does the following fragment of code display? What do you think the programmer intended the code to do, and how would you fix it? int product = 1; int max = 20; for (int i = 0; i <= max; i++) product = product * i; System.out.println("The product is " + product);
Answer:
0
Explanation:
Given the code segment:
int product = 1; int max = 20; for (int i = 0; i <= max; i++) product = product * i; System.out.println("The product is " + product);Since the counter i in the for loop started with 0, and therefore product * i will always be 0 no matter how many rounds of loop to go through.
The code is likely to perform factorial calculation. To do so, we need to change the starting value for the counter i to 1.
int product = 1; int max = 20; for (int i = 1; i <= max; i++) product = product * i; System.out.println("The product is " + product);For reproducibility needed for auto-grading, seed the program with a value of 2.

Note: A common student mistake is to create an instance of Random before each call to rand.nextInt(). But seeding should only be done once, at the start of the program, after which rand.nextInt() can be called any number of times.

What will be the value of discountRate after the following statements are executed? double discountRate = 0.0; int purchase = 100; if (purchase > 1000) discountRate = 0.05; else if (purchase > 750) discountRate = 0.03; else if (purchase > 500) discountRate = 0.01;
The value of discountRate after the following statements are executed
double discountRate = 0.0;
int purchase = 100;
if (purchase > 1000) discountRate = 0.05;
else if (purchase > 750) discountRate = 0.03;
else if (purchase > 500) discountRate = 0.01;
is 0.0
Explanation:
The discount rate is declared as a double; double discountRate = 0.0;
The purchase is declared as integer; int purchase = 100;
The first if statement shows if purchase > 1000 then the discountRate is 0.05
The second if statement shows if purchase > 750then the discountRate is 0.03
The third if statement shows if purchase > 500 then the discountRate is 0.01
Since none of these statements are true, the original discountRate is printed.
Final answer:
After executing the statements, the value of discountRate will remain 0.0 because the purchase amount does not meet any of the specified conditions to receive a discount.
Explanation:
The value of discountRate after executing the given statements will be 0.0. The code snippet provided is a series of conditional statements that assign a value to the variable discountRate based on the value of the variable purchase.
The initial value of purchase is 100, which does not satisfy any of the given conditions for increasing the discountRate (i.e., purchase must be greater than 500, 750, or 1000 to get a discount). Therefore, the discountRate remains at its initial value of 0.0 since no conditions are met.
