Once sales are​ forecasted, ________ must be generated to estimate required raw materials. A. a pro forma statement B. a production plan C. a cash budget

Answers

Answer 1

Answer:

Option B i.e., a production plan.

Explanation:

While sales are estimated, the manufacturing schedule for estimating the necessary raw materials should be produced.

So when the revenue is already estimated then at that time the manufacturing schedule should be produced approximately that raw material which is needed, so the following option is correct according to the scenario.

Option a is incorrect because it is not related to the following scenario.Option B is incorrect because in the above statement, it is not mentioned or related to the budget plan.

For a line segment, show that clipping against the top of the clipping rectangle can be done independently of the clipping against the other sides. Use this result to show that a clipper can be implemented as a pipeline of four simple clippers.

Answers

Final answer:

The answer explains the concept of clipping in geometry and how it relates to implementing clippers in a pipeline. It also discusses the proofs and theorems in geometry regarding segments, polygons, and constructions using straight-edge and transferer of segments.

Explanation:

Clipping against the top of the clipping rectangle can be done independently of the other sides due to the nature of line segments. This concept is essential in implementing a clipper as a pipeline of four simple clippers.

Proofs and theorems in geometry demonstrate the relationships and properties of segments, polygons, and shapes in a structured manner.

Understanding the construction using straight-edge and transferer of segments allows for solving a variety of geometrical problems by drawing straight lines and laying off segments.

Suppose Host A wants to send a large file to host B. The path from Host A to Host B has three links, of rates R1 = 500 kbps, R2=2 Mbps, and R3 = 1 Mbps. Assuming no other traffic in the network, what is the throughput for the file transfer? 500 kbps

Answers

Answer:

500kbps

Explanation:

Bandwidth is the actual amount of data that a network is capable of transferring theoretically.

Throughput is the actual amount of data passing through a connection. It is the rate (usually measured in bps- bits per sec or pps - packets per second) at which packets or bits are successfully delivered over a network channel

If R₁=500 kbps, R₂=2 Mbps, and R₃ = 1 Mbps.

Since there is no other traffic in the link from Host A to Host B, the Throughput is the minimum of the links between Host A and Host B. Therefore:

Throughput= Mininum(R₁,R₂,R₃)

=500kbps

Write a program named ArrayDemo that stores an array of 10 integers. (Note that the array is created for you and does not need to be changed.) Until the user enters a sentinel value, allow the user four options: (1) to view the list in order from the first to last position in the stored array (2) to view the list in order from the last to first position (3) to choose a specific position to view (4) to quit the application.

Answers

Answer:

Hi Zoom! Good question. This is particularly useful for learning sorting functions in arrays and user input handling as well. Please find the implementation below.

Explanation:

I have implemented the code in Python 2+. You can save the below code into a file called ArrayDemo.py and then run it from the command line with the command "python ArrayDemo.py". I have declared the demo_array in the code to an array of 10 unsorted integer values to test this. You can change the code if needed to have this array input by user as well and it should work fine.

Note: if you're using Python 3+ then you'll need to change the "raw_input" in the code to just "input" to make it work.

ArrayDemo.py

demo_array = [2,1,3,4,5,7,6,8,10,9]

option = 0

while (option != 4):

 option = raw_input("Enter 1 to view list in ascending order, 2 to view list in descending order, 3 to choose specific poisition to view, 4 to quit the application: ")

 try:

   option = int(option)

   if option == 1:

     sort_by = 'asc'

     print(sorted(demo_array, reverse=False))

   elif option == 2:

     sort_by = 'desc'

     print(sorted(demo_array, reverse=True))

   elif option == 3:

     position = raw_input("Enter specific position to view (0-9): ")

     try:

       position = int(position)

       if position < 0 or position > 9:

         print("Position does not exist")

       else:

         print(demo_array[position])

     except ValueError:

       print("Position does not exist!")

   elif option == 4:

     break

   else:

     break

 except ValueError:

   print("Invalid input!")

The actual methods used to protect against data loss are __________ controls, but the program that identifies which data to protect is a ___________ control.

Answers

Answer:

The actual methods used to protect against data loss are Technical controls, but the program that identifies which data to protect is a Procedural control.

Explanation:

In technical control, different software has been installed and protocols has been deployed to avoid any data loss in network security. As all the devices and protocols that we need while installing a network needs technical support. This is the reason, these things are called technical control of the system.

Another control in network security is procedural control. In this type of control it has been identified that, which data should be protected or which data should not be accessed to unauthorized users. This is called procedural control.

What is the value of the cost variable after the following code snippet is executed? int cost = 82; if (cost < 100) { cost = cost + 10; } if (cost > 50) { cost = cost * 2; } if (cost < 100) { cost = cost - 20; }

Answers

Answer:

184

Explanation:

Given the codes

       int cost = 82;        if (cost < 100)        {            cost = cost + 10;        }        if (cost > 50)        {            cost = cost * 2;        }        if (cost < 100)        {            cost = cost - 20;        }

The initial value of cost is 82.

The if condition in Line 3 will pass and therefore cost = 82 + 10 = 92

The if condition in Line 8 will pass and therefore cost = 92 * 2 = 184

The if condition in Line 13 will fail l and therefore the if block will be skipped.

At last, the we get cost = 184.

Agile methods use rapid development cycles to iteratively produce running versions of the system. How would these shorter cycles affect the ability of the analyst to manage system’s requirements?

Explanation:

Iterative production or procedure seems to be a technique of distinguishing product progression from expansive implementation to littler bits. This including code in regurgitated processes is designed, developed and attempted.

Regularly iterative architecture is used in conjunction with gradual improvement where a certain more sketched-out process of code progress is composed of littler components building on each other.

Time-consuming.Better testing.Better product.Review of code.

This will improve observer performance, as each move is systematic and cheap to run.

The shorter cycles of Iterative production affect the ability of the analyst to manage system’s requirements in a way that improve the observer performance as each move is systematic and cheap to run.

Your friend has a Lenovo IdeaPad N580 laptop, and the hard drive has failed. Her uncle has offered to give her a working hard drive he no longer needs, the Toshiba MK8009GAH 80-GB 4200-RPM drive. Will this drive fit this laptop? Why or why not?a. Yes, the drive form factor and interface connectors match.b. No, the drive form factor matches but the interface does not match.c. Yes, the drive form factor, spindle speed, and interface all match.d. No, the drive form factor and interface do not match.

Answers

Solution:

It will not fit on Lenovo Ideapad N580.

The Ideapad N580 will fit HDD of form factor 2.5" (2.5 Inch) but the form factor of Toshiba mk8009GAH is 1.8" hence won't fit in the slot.

The interface type specifies which type of connector used to connect the motherboard and the HDD and it should be the same in order to use on it.

Ideapad uses the SATA interface type to connect the HDD but the Toshiba mk8009GAH is having an ATA type interface on it hence they cannot be connected with each other.

Final answer:

No, the Toshiba MK8009GAH 80-GB 4200-RPM hard drive will not fit in the Lenovo IdeaPad N580 laptop because it is a 1.8-inch PATA (IDE) drive, while the laptop requires a 2.5-inch SATA drive.

Explanation:

To determine if the Toshiba MK8009GAH 80-GB 4200-RPM hard drive will fit in the Lenovo IdeaPad N580 laptop, we'll need to consider both the drive form factor and interface connector compatibility. Most laptops, including the Lenovo IdeaPad N580, use a 2.5-inch SATA hard drive. The Toshiba MK8009GAH, however, is an older 1.8-inch PATA (IDE) drive (as indicated by its 4200-RPM speed which is more common in older drives, and the MK series which was typically PATA drives).

The answer is d. No, the drive form factor and interface do not match. The physical size (form factor) of the Toshiba drive is smaller and the interface is IDE, not SATA. Therefore, this drive would not fit nor connect properly without an appropriate adapter, which typically is not a feasible solution for replacing a laptop hard drive.

Write a method swapArrayEnds() that swaps the first and last elements of its array parameter. Ex: sortArray = {10, 20, 30, 40} becomes {40, 20, 30, 10}.

Answers

Final answer:

The swapArrayEnds() method exchanges the positions of the first and last elements in an array. For an array with two or more elements, the method uses a temporary variable to hold one element during the swap. This method is a basic array manipulation technique in programming.

Explanation:

The method swapArrayEnds() swaps the first and last elements of an array. In a programming language like Java or Python, this task is typically performed by accessing the elements at their respective indices and then swapping their values. Here’s an example of how you might write this method in Java:

void swapArrayEnds(int[] array) {
   if(array != null && array.length > 1) {
       int temp = array[0];
       array[0] = array[array.length - 1];
       array[array.length - 1] = temp;
   }
}

By checking if the array is not null and has more than one element, we ensure that we do not try to swap ends on an empty or single-element array, which would be unnecessary. This is a common operation in array manipulation, and understanding how to implement it is useful in many programming and computer science applications.

Suppose you were assigned to develop a logical model of the registration system at a school or college. Would you be better off using a top-down approach, or would a bottom-up strategy be better

Answers

Answer:

top down approach

Explanation:

Top down approach is process of breaking down system into sub-system which helps in formulating the overall system. At the end every sub system can be refined with more details.

While bottom up approach is process of gathering systems to design large complex system.

Top down is better as basic information is present and resources can be utilized effectively without impacting maintennance and operations.

Final answer:

Choosing between a top-down approach and a bottom-up approach for developing a school registration system depends on the project goals and context. A top-down approach is hierarchically structured and policy-driven, while a bottom-up approach focuses on detailed, user-centric components. A hybrid approach may offer the best of both methodologies.

Explanation:

When developing a logical model of a registration system at a school or college, choosing between a top-down approach and a bottom-up approach depends on the specific context and goals of the project. A top-down approach generally starts with defining the high-level processes and structures of the system based on the policies and requirements of the institution. It is methodical, following a hierarchical path from the general to the specific, which can be beneficial when there are clear objectives and standards to adhere to.

On the other hand, a bottom-up approach builds the system from the lowest level of detailed requirements, often focusing on user needs and individual system components before integrating them into the full model. This can be advantageous when needing to understand complex details from the outset or when user feedback is critical in shaping the system's functionality.

In the implementation phase of a policy process, one might consider elements from both strategies. For example, important federal policies might require adherence to regulations (top-down), but the practical and on-the-ground impact of policies might be best understood by considering local circumstances (bottom-up). Thus, developing a registration system could potentially benefit from a hybrid approach, combining the structured, policy-driven aspects of the top-down method with the detailed, user-driven focus of the bottom-up method.

4.15 LAB: Mad Lib - loops Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and integer as input, and outputs a sentence using those items as below. You may assume that the string does not contain spaces.The program repeats until the input is quit 0. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away. Note: This is a lab from a previous chapter that now requires the use of a loop. LAB ACTIVITY 4.15.1: LAB: Mad Lib - loops 0 / 10

Answers

Final answer:

This answer provides C++ and Python code for a Mad Libs game that uses loops to generate sentences based on user inputs until 'quit 0' is entered.

Explanation:

This lab activity requires the creation of a Mad Libs game using loops in both C++ and Python programming languages. The game will prompt users to input a string and an integer, and use those inputs to construct and output a humorous sentence. The loop will terminate when the user inputs 'quit 0'. Below you'll find an example code snippets in C++ and Python that accomplish this task.

C++ Example

Write complete code in C++ to create a Mad Libs game that continues to ask for user inputs until 'quit 0' is entered:

#include
#include
using namespace std;

int main() {
   string word;
   int number;
   while (true) {
       cin >> word;
       if (word == "quit") {
           cin >> number;
           if (number == 0) {
               break;
           }
       }
       cin >> number;
       cout << "Eating " << number << " " << word << " a day keeps the doctor away." << endl;
   }
   return 0;
}

Python Example

Write complete code in Python to accomplish the same task:

while True:
   word, number = input().split()
   number = int(number)
   if word == 'quit' and number == 0:
       break
   print(f'Eating {number} {word} a day keeps the doctor away.')

As part of the systems engineering development team, use IDEF0 to develop a functional architecture. The functional architecture should address all of the functions associated with the ATM. This functional architecture should be at least two levels deep and should be four levels deep in at least one functional area that is most complex. Note that you will be graded on your adherence to proper IDEF0 semantics and syntax, as well as the substance of your work.

Pick three scenarios from the operational concept and describe how these scenarios can be realized within your functional architecture by tracing functionality paths through the functional architecture. Start with the external input(s) relevant to each scenario and show how each input(s) is(are) transformed by tracing from function to function at various levels of the functional decomposition, until the scenario's output(s) is(are) produced. Highlight with three different colors (one color for each scenario) the thread of functionality associated with each of these three scenarios.

If your functional architecture is inadequate, make the appropriate changes to your functional architecture.239

As part of the systems engineering development team for the ATM, update your requirements document to reflect any insights into requirements that you obtained by creating a functional architecture. That is, if you added, deleted, or modified any input, controls, or outputs for the system, modify your input/output requirements.

Security is an essential aspect in any company and for any software organization, through a better protected area or network, the company will be able to maintain important data and operations with access for only authorized users.

Currently, there is a network of hackers and intruders of IT systems whose intention is to steal relevant data and obtain financial benefits from the invasion of company systems, so the IT infrastructure must be a planned and well implemented step in companies, to avoid intruders and failures that could harm an organization's operations.

The ideal IT structure is one developed to meet the needs of a company and its professionals, so there is a need for research, testing and for the implementation of the system to be directed at strategies and organizational objectives.

Another important factor is the development of the policy that will guide the rules and conduct for using the IT system, it is necessary that the policy has the ideal flexibility for the company, so that all its development is focused on coherence and cohesion with the company's strategy must be comprehensive to establish usage rules for users and authentication procedures for specific networks.

Write a function maxTemp which takes a filename as string argument and returns the maximum temperature as float type for the week. Input file will contain temperature readings for each day of the week. Your function should read each line from the given filename, parse and process the data, and return the required information. Your function should return the highest temperature for the whole week. Empty lines do not count as entries, and should be ignored. If the input file cannot be opened, return -1. Remember temperature readings can be decimal and negative numbers.

Answers

Answer:

The solution is written in Python 3

def maxTemp(fileName):    try:        with open(fileName) as file:            raw_data = file.readlines()            highest = 0            for row in raw_data:                if(row == "\n"):                    continue                                data = float(row)                if(highest < data):                    highest = data            return highest    except FileNotFoundError as found_error:        return -1 higestTemp = maxTemp("text1.txt") print(higestTemp)

Explanation:

Firstly, create a function maxTemp that take one input file name (Line 1). Next create an exception handling try and except block to handle the situation when the read file is not found or cannot be open, it shall return -1 (Line 2, Line 15 -16).

Next use the readlines method to read the temperature data from the input file (Line 4). Before we traverse the read data using for loop, we create a variable highest to hold the value of max temperature (Line 5). Let's set it as zero in the first place.

Then use for loop to read the temp data line by line (Line 6) and if there is any empty line (Line 7) just ignore and proceed to the next iteration (Line 7 -8). Otherwise, the current row reading will be parsed to float type (Line 10) and the parsed data will be check with the current highest value. If current highest value is bigger than the current parsed data (), the program will set the parse data to highest variable (Line 11 -12).

After finishing the loop, return the highest as output (Line 14).

(a) How many segments has host A sent in total and how many ACKs has host B sent in total? What
are their sequence number? Answer this question for all three protocols.
(b) If the timeout values for all three protocols are much longer than 5 RTT, then which protocol
successfully delivers all five data segments in the shortest time interval?

Answers

Answer:

The explanation of the question is described in the section below.

Explanation:

(a)

Go Back N :

A gives in a maximum of 9 pieces. Typically they will be sent back sections 1, 2, 3, 4, 5 and then re-sent segments 2, 3, 4 and 5.

B sends out 8 ACK's. They are 4 ACKS including 1 series and 4 ACKS with 2, 3, 4 and 5 series amounts.

Selective Repeat :

A sends in such max of 6 bits. Subsequently, segments 1, 2, 3, 4, 5 and earlier re-sent Segments 2 will be sent.

B assigns five ACKs. We are 4our ACKS with numbers 1, 3, 4, 5. However there is one sequence quantity 2 ACK.

TCP :

A assigns in a total of 6 bits. Originally, segments 1, 2, 3, 4, 5 and future re-sent Segments 2 have always been sent.

B sends five ACKs. There are 4 ACKS with either the number 2 series. There has been one ACK with a sequence of numbers 6. Remember that TCP always needs to send an ACK with a sequence number you anticipate.

(b)

This is although TCP utilizes convenient retransmission without searching for the time out.

So, it's the right answer.

"Suppose that a program's data and executable code require 1,024 bytes of memory. A new section of code must be added; it will be used with various values 35 times during the execution of a program. When implemented as a macro, the macro code requires 61 bytes of memory. When implemented as a procedure, the procedure code requires 168 bytes (including parameter-passing, etc.), and each procedure call requires 6 bytes. How many bytes of memory will the entire program require if the new code is added as a macro

Answers

Answer:

3,159 bytes

Explanation:

When implemented as a macro, for each of the 35 executions, the program will require enough memory for the whole macro code (61 bytes). Since the program's data and executable code require 1,024 bytes, the number of bytes required by the entire program is:

[tex]M = 1,024+(35*61)\\M=3,159\ bytes[/tex]

The program requires 3,159 bytes if the new code is added as a macro.

2 – [4 pts] Imagine that you are an application developer. A new version of your operating system is released with several changes made to the transport layer protocols. Specifically, the algorithm for TCP has been changed from Tahoe to Reno. What changes must be made to your application to accommodate these changes?

Answers

Answer:

TCP convention is totally connection oriented, it searches for the information that was going in the system definitely and will guarantee an affirmation on the parcel sent, likewise if the uplayer convention is down, it won't permit to move the information, fundamentally it will guarantee there is no any bundle misfortune during the exchange.  

~ However UDP is connectionless convention, there is no any affirmation business in UDP convention, it regularly utilized where not many datagram misfortune doesn't a make a difference. It was nearly a light gauge convention.  

So underneath are sway we will confront, if TCP is expelled.  

1. There will association foundation required in information move, so the application will work minimal quicker.  

2. without appropriate information control and affirmations, there is gigantic possibility for information misfortune.  

3. Presently the application needs to depend totally on UDP, since UDP doesn't has blockage control, the application will get clogged.  

4. Likewise the communication with top layer convention will be a wreck, it won't look if the layers are down or not. so if any upper layer is down, consequently the information will stuck the system, can't capable arrive at the goal.

Explanation:

Switching to TCP Reno from Tahoe requires adapting to faster congestion recovery and retransmission strategies. Applications should adjust for improved throughput and handling of packet loss signals.

Switching the TCP algorithm from Tahoe to Reno in the operating system affects how your application interacts with the network, particularly in terms of congestion control and handling of packet loss. Here are the key changes you would need to consider and potentially address in your application:

1. Congestion Control Behavior: Reno TCP introduces Fast Recovery and Fast Retransmit mechanisms, which allow faster recovery from packet loss compared to Tahoe. Your application should be aware of these behaviors, especially in scenarios where it needs to manage large data transfers or real-time communications. It may need to adjust its own congestion control strategies or settings to optimize performance with Reno TCP.

2. Handling of Packet Loss: Reno TCP reacts differently to packet loss compared to Tahoe. Instead of immediately halving the congestion window (as Tahoe does), Reno enters Fast Recovery, retransmits the lost packet, and then adjusts its congestion window dynamically. Your application should be prepared for potentially different patterns of packet loss and recovery, which could affect application-level retransmission strategies or timeouts.

3. Performance Monitoring and Tuning: With the change to Reno TCP, monitoring and tuning network performance metrics becomes crucial. Your application may need to adapt its monitoring mechanisms to track parameters specific to Reno's congestion control algorithms, such as congestion window size, packet retransmission rates, and round-trip time estimates.

4. Compatibility and Testing: Ensure compatibility with both Tahoe and Reno TCP variants during transitional periods. Your application should be able to gracefully handle connections with both types of TCP algorithms to support users who have not yet upgraded their operating systems.

5.Documentation and User Communication: Update documentation and inform users about any changes in network behavior or performance optimizations that may result from switching to Reno TCP. Provide guidance on configuring your application to leverage Reno's improvements effectively.

By considering these factors and making necessary adjustments in your application, you can ensure optimal performance and compatibility with the new Reno TCP algorithm introduced in the operating system update.

Briefly describe the interface between the memory and the processing unit. That is, describe the method by which the memory and the processing unit communicate.

Answers

Answer:

The memory and the processing unit communicate through the Memory Address Register (MAR) and the Memory Data Register (MDR).

Explanation:

Final answer:

The memory and processing unit in a computer communicates through the system bus, utilizing RAM for fast access to data. This interaction is optimized with techniques like caching and, when necessary, swapping to manage memory usage effectively.

Explanation:

The interface between the memory and the processing unit in a computer system facilitates communication and data exchange crucial for computational tasks. These two components communicate through a data pathway known as the system bus. This bus includes data lines for transferring data, address lines to specify where the data should be sent, and control lines to manage the timing and direction of data flow.

Random Access Memory (RAM) plays a pivotal role in this communication. When a process is initiated, data from the long-term storage (like a hard drive) is loaded into RAM, because RAM is much faster, though more expensive. The processing unit (CPU) then reads instructions and data directly from RAM, performs computations, and may write the results back to RAM or send them to output devices or long-term storage.

Another method to facilitate communication involves caching. CPU caches are small, faster memory locations that store copies of the data from frequently used main memory locations. These caches help reduce the time it takes for the CPU to access data from RAM, speeding up the computation process.

To manage and optimize memory use, operating systems may employ techniques like swapping, where data is moved back and forth between RAM and a hard drive, particularly when RAM is full. However, this can significantly slow down system performance due to the difference in speed between RAM and hard drives.

1. The programmer intends for this pseudocode to display three random numbers in the range of 1 through 7. According to the way we’ve been generating random numbers in this book, however, there appears to be an error. Can you find it?

Answers

Answer:

Display random(1, 7).

Explanation:

In the following question, some details of the question are missing that is pseudocode.

//  Program shows three random numbers

// the range of 1 to 7.

Declare the Integer count

// Shows three random numbers.

For count = 1 To 3

Display random(7, 1)

End For

In the following pseudocode, it generates three random numbers from 1 to 7 because the for loop statement is starts from 1 and end at 3 so the loop will iterate three times and every time it generates one random number from 1 to 7. So, the following are the reason that describe the answer is correct according to the scenario.

Final answer:

The issue with the pseudocode might be related to the exclusive nature of the upper boundary in many random number generator methods. The programmer may need to add 1 to the function to generate values inclusive of 7.

Explanation:

Without seeing the actual pseudocode, it's tough to give a specific correction. However, the common error in generating random numbers is not considering the exclusive nature of the upper boundary in random number methods. Most methods generate numbers from 0 (inclusive) up to the specified upper limit number (exclusive).  To generate random numbers within the range from 1 to 7 (inclusive), the code should add 1 to the random output. Therefore, a possible correction would be to modify the random number generator function to include 7 and exclude 0.

For example, in many programming languages, one could use a function similar to '1 + Math.floor(Math.random() * 7)', ensuring that we generate random numbers between 1 and 7 inclusive. Kindly refer to the specific programming language practices when implementing.
