8. (10pts) suppose we have a system that uses dynamic partitioning with 32m of memory, and the following events happen in order: p1, 9m, is launched p2, 3m, is launched p3, 15m, is launched p4, 2m, is launched p1 is suspended p5, 2m is launched p6, 3m is launched p7, 2m is launched p6 finishes p8, 2m is launched p4 finishes give a diagram like from the notes showing the change on memory with each event for each of the placement algorithms: best-fit, first-fit, and next-fit. is there enough memory to unsuspend p1? can p1 be unsuspended for any of the placement algorithms? why or why not?

Answers

Answer 1

First, let's define the three placement algorithms:

Best-fit: allocates memory to the smallest partition that is big enough to fit the process.First-fit: allocates memory to the first partition that is big enough to fit the process.Next-fit: allocates memory to the next partition that is big enough to fit the process, starting from the last allocated partition and wrapping around to the beginning when the end is reached.

Using these algorithms, we can create the following memory diagrams for each event:

Best-fit:

| Free (32m) |

| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

| p1 (9m) | Free (23m) |

| p2 (3m) | Free (20m) |

| p3 (15m) | Free (5m) |

| p4 (2m) | p7 (2m) | p8 (2m) | p5 (2m) |

| Free (1m) | p6 (3m) | Free (2m) | Free (2m) |

First-fit:

| Free (32m) |

| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

| p1 (9m) | Free (23m) |

| p2 (3m) | Free (20m) |

| p3 (15m) | Free (5m) |

| p4 (2m) | p7 (2m) | p8 (2m) | p5 (2m) |

| Free (1m) | p6 (3m) | Free (2m) | Free (2m) |

Next-fit:

| Free (32m) |

| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |

| p1 (9m) | Free (23m) |

| p2 (3m) | Free (20m) |

| p3 (15m) | Free (5m) |

| p4 (2m) | p7 (2m) | p8 (2m) | p5 (2m) |

| p6 (3m) | Free (2m) | Free (2m) | Free (1m) |

Note: In the Next-fit diagram, we start at the end of the last allocated partition (p4) for the next allocation, which is p6.

From these diagrams, we can see that there is not enough contiguous memory to unsuspend p1, which requires 9m. None of the placement algorithms can unsuspend p1 because there is not enough memory in any one partition to fit it.

The adoption of ---- has been an important factor in the development of the Internet of Things 1. IPv6 2. IPv8 3. IPv4 4. IPv2

Answers

The adoption of IPv6 has been an important factor in the development of the Internet of Things.

The Internet of Things (IoT) is a network of interconnected physical devices, vehicles, buildings, and other objects that are embedded with sensors, software, and network connectivity, allowing them to collect and exchange data. The adoption of IPv6 (Internet Protocol version 6) has been an important factor in the development of IoT because it provides a vastly expanded address space for internet-connected devices. IPv6 is designed to replace IPv4, which has a limited address space that cannot accommodate the growing number of devices that require internet connectivity. IPv6 uses a 128-bit address space, which allows for a virtually unlimited number of unique addresses, making it possible to connect billions of devices to the internet. IPv8 and IPv2 are not currently used in the internet protocol and are not relevant to the development of IoT. IPv8 was a proposed protocol that was never implemented, while IPv2 was an early version of the protocol that was superseded by IPv3 and IPv4.

5.18 lab: swapping variables write a program whose input is two integers and whose output is the two integers swapped. ex: if the input is: 3 8 the output is: 8 3 your program must define and call the following function. swap values() returns the two values in swapped order. def swap values(user val1, user val2)

Answers

The program should take two integers as input and output those two integers swapped. To accomplish this task, you need to define a function called "swap values()" which takes two user values as input (let's call them val1 and val2) and returns these values in swapped order.

Here's an example of what the code might look like: ``` # Define the swap values function def swap_values(val1, val2): # Store the value of val1 in a temporary variable temp = val1 # Set val1 equal to val2 val1 = val2 # Set val2 equal to the temporary variable (which holds the original value of val1) val2 = temp # Return the swapped values return val1, val2 # Take user input for val1 and val2 user_val1 = int(input("Enter an integer for val1: ")) user_val2 = int(input("Enter an integer for val2: ")) # Call the swap values function and print the swapped values swapped_val1, swapped_val2 = swap_values(user_val1, user_val2) print("Swapped values: ", swapped_val1, swapped_val2) ``` In this program, we define the function `swap_values()` which takes two input parameters `val1` and `val2`. Inside the function, we use a temporary variable `temp` to store the value of `val1`. Then, we set `val1` equal to `val2` and `val2` equal to `temp` (which holds the original value of `val1`). Finally, we return the swapped values. To get the user input for `val1` and `val2`, we use the `input()` function to take input from the user and convert it to an integer using the `int()` function. Then, we call the `swap_values()` function with the user input values as parameters and store the swapped values in `swapped_val1` and `swapped_val2`. Finally, we print the swapped values using the `print()` function.

What does the agile estimation technique of ideal days ignore, discount, or simplify?

Answers

The agile estimation technique of "ideal days" is a simplified approach to estimating the amount of time it will take to complete a particular task or project.

This technique is often used in Agile software development methodologies like Scrum, and it involves estimating the number of "ideal" working days it will take to complete a task, assuming that there are no interruptions, distractions, or delays.

However, the ideal days approach does ignore, discount, or simplify several factors that can affect the actual time required to complete a task, including:

Interruptions and distractions: In reality, it is rare for someone to work on a task uninterrupted for an entire day. The ideal days approach assumes that the person will be able to work on the task without any interruptions or distractions, which is often not the case.Unexpected issues: The ideal days approach assumes that everything will go smoothly during the task and there will be no unexpected issues that arise. However, this is often not the case, and unexpected issues can significantly delay the completion of a task.Complexity: The ideal days approach assumes that the task is relatively straightforward and can be completed within a set amount of time. However, if the task is more complex than initially anticipated, it may require more time and effort to complete.Skill level and experience: The ideal days approach assumes that the person working on the task is skilled and experienced enough to complete it within the estimated timeframe. However, if the person lacks the necessary skills or experience, it may take them longer to complete the task.

Spanning tree blocking refers to the mechanism that prevents loops in network topology by disabling redundant links. Layer 2 interfaces support this mechanism by blocking or unblocking certain ports based on their roles in the spanning tree protocol.

Forwarding of spanning tree BPDUs (Bridge Protocol Data Units) is another important function of Layer 2 interfaces. BPDUs are used to exchange information about the network topology and ensure that the spanning tree protocol is functioning properly. Layer 2 interfaces support the forwarding of BPDUs between switches.

Routing is the process of forwarding packets between networks. While Layer 2 interfaces do not perform routing themselves, they can be used to connect different networks or VLANs to a router that performs the actual routing function.

Traffic examination, traffic shaping via QoS, and firewall management are not functions supported by Layer 2 interfaces. These functions are typically performed by Layer 3 devices such as routers and firewalls.

An Agile team estimated a story at 4 ideal days. If the team size is doubled, how would that impact the story size estimate?

Answers

When an Agile team estimates a story at 4 ideal days, it means that the team believes it will take 4 days of focused work to complete the story. If the team size is doubled, the impact on the story size estimate depends on various factors such as the complexity of the task, communication, and coordination among team members.



In some cases, the increased team size may reduce the completion time as more resources are available. However, it does not always guarantee that the story size estimate will be halved to 2 ideal days. This is because tasks may not be perfectly divisible, and adding more team members can increase coordination and communication efforts, potentially affecting overall efficiency.
In conclusion, doubling the team size could lead to a faster completion of the story, but the impact on the story size estimate is not always proportional to the increase in team members. Agile teams should continuously reassess the estimates and adapt their planning accordingly.

This may involve regular performance reviews, feedback mechanisms, performance improvement plans, or other systematic approaches to ensure that performance is continuously assessed, address, and optimized.

Performance accountability: A culture of accountability that holds individuals, teams, or entities responsible for meeting their performance expectations. This includes clear consequences for performance outcomes, both positive and negative, and mechanisms for addressing performance gaps or issues in a timely and appropriate manner.

Performance alignment: Alignment of performance expectations and structures with overall organizational goals, strategies, and values. This ensures that individual or team performance is aligned with the broader organizational direction and contributes to its success.

Performance transparency: Transparency in performance expectations, structures, and processes, where relevant stakeholders have access to information about performance criteria, progress, and outcomes. This fosters trust, open communication, and collective understanding of performance expectations and outcomes.

Continuous improvement: An emphasis on continuous improvement of performance expectations, structures, and processes, based on feedback, data, and insights. This involves regularly reviewing and updating performance expectations and structures to ensure they remain relevant, effective, and aligned with changing organizational needs.

Supportive resources: Adequate resources, such as tools, technology, training, and support, that are necessary to enable individuals, teams, or entities to meet their performance expectations. This includes identifying and addressing any barriers or gaps in resources that may impede performance.

Fairness and equity: Fair and equitable treatment of individuals, teams, or entities in terms of performance expectations, structures, and processes, to ensure that they are based on objective criteria, applied consistently, and free from bias or discrimination.

Communication and feedback: Open and effective  channels and feedback mechanisms that enable regular exchange of information, expectations, and feedback related to performance. This promotes clarity, understanding, and collaboration in achieving performance expectations.

When does an Agile team reconfirm its commitments and identify project impediments?

Answers

Thus, an Agile team regularly reconfirms its commitments and identifies project impediments throughout the project lifecycle to ensure that they are continuously improving and delivering value to the customer.

An Agile team typically reconfirms its commitments and identifies project impediments during regular meetings, such as daily stand-ups, sprint planning, sprint reviews, and retrospectives.

During the daily stand-up meeting, team members discuss their progress since the last meeting, any impediments they are facing, and what they plan to work on next. This meeting is a quick and efficient way for the team to stay aligned and address any issues in real-time.During sprint planning, the team reviews the goals for the upcoming sprint and decides what work they will commit to completing. This is an opportunity for the team to discuss any potential impediments and make a plan for addressing them.During the sprint review, the team demonstrates the work they completed during the sprint and receives feedback from stakeholders. This meeting provides an opportunity to identify any impediments that arose during the sprint and discuss how they were addressed.Finally, during the retrospective, the team reflects on the previous sprint and identifies what went well, what didn't go well, and what they can improve on in the next sprint. This is a key opportunity to identify project impediments and develop a plan to address them.

Overall, an Agile team regularly reconfirms its commitments and identifies project impediments throughout the project lifecycle to ensure that they are continuously improving and delivering value to the customer.
