The technique that allows the parent and child processes to initially share the same pages, but when either process modifies a page, a copy of the shared page is created is called copy-on-write.
Copy-on-write (COW) is a memory management technique used by many operating systems, including Unix and Linux, to optimize the copying of memory pages. When a parent process creates a child process, the child process initially shares the same memory pages as the parent process. However, when either the parent or child process modifies a shared memory page, a new copy of that page is created, and the modifications are made to the new copy. This allows the parent and child processes to share memory pages without the overhead of copying pages unnecessarily.
COW can be implemented in various ways, but a common approach is to use page-level protection. Initially, the parent and child processes share memory pages with read-only access. When a process attempts to modify a shared page, a page fault occurs, and the operating system creates a new copy of the page with write access for the modifying process.

Cache types that are generally implemented on the same chip as the CPU include __________ and__________.
The cache is a type of memory that is designed to improve computer performance by storing frequently accessed data closer to the CPU. There are several types of cache, including L1, L2, and L3 cache. L1 cache is the smallest and fastest cache, while L3 cache is the largest but slower. Generally, cache types that are implemented on the same chip as the CPU include L1 and L2 cache.
L1 cache is the fastest type of cache, with a very low latency of just a few cycles. It is typically very small, with a capacity of a few kilobytes. L2 cache, on the other hand, is slightly slower than L1 cache but has a much larger capacity, typically in the range of a few megabytes. It is also more expensive to manufacture and is usually shared among multiple cores in a multi-core CPU.
In summary, the cache types that are generally implemented on the same chip as the CPU include L1 and L2 cache. L1 cache is the fastest but has a small capacity, while L2 cache is slower but has a larger capacity. Both types of cache are essential for improving computer performance by reducing the time it takes to access frequently used data.

"What type of attack is being performed when multiple computers overwhelm a system with fake requests?
a. DDoS
b. DoS
c. SYN flood
d. replay attacks "
When multiple computers overwhelm a system with fake requests, this is known as a Distributed Denial of Service (DDoS) attack. This type of attack aims to disrupt the normal functioning of a website or online service by flooding it with a massive amount of traffic from multiple sources.
The goal of the attack is to exhaust the resources of the target system, rendering it unavailable to legitimate users. In a DDoS attack, the fake requests come from many different computers, making it difficult to trace the source of the attack. Attackers typically use malware or botnets to control these computers remotely and direct them to flood the target system with traffic. The fake requests may also be designed to mimic legitimate traffic, making it even harder to distinguish between real and fake requests. DDoS attacks can be particularly damaging to businesses and organizations that rely heavily on their online presence. Such attacks can cause significant financial losses, damage to brand reputation, and loss of customer trust. To mitigate the risk of a DDoS attack, organizations can implement various security measures, including network firewalls, intrusion prevention systems, and DDoS mitigation services. It's also essential to have a response plan in place to quickly detect and respond to any attacks that occur.

You have recently taken over leadership of an Agile team that is halfway through a complicated project. You have recently examined project requirements and now want to get an idea of team velocity. Which document should provide some insight on the team's velocity?
To get an idea of the Agile team's velocity in a complicated project, the document that would provide some insight is the team's sprint backlog, which contains the list of user stories or tasks that the team has committed to complete during a sprint.
The sprint backlog is a dynamic document that is typically maintained by the Agile team and is used to track the progress of work during a sprint. It includes the user stories or tasks that have been estimated, prioritized, and selected for the current sprint, along with their corresponding status (e.g., to-do, in progress, done).
By examining the team's sprint backlog, a project manager can gain insights into the team's velocity, which is a measure of the amount of work the team is able to complete during a sprint. Velocity is typically calculated as the sum of the story points or task points completed by the team in a sprint.
By comparing the completed story points or task points from previous sprints, a project manager can assess the team's velocity over time. This can provide valuable information for planning and forecasting, as it helps the project manager and the team to estimate how much work can be completed in future sprints and make adjustments to the project timeline or scope as needed.
It's important to note that velocity is not a fixed or absolute measure, and it can vary depending on factors such as team composition, sprint duration, complexity of work, and external dependencies. It's a useful tool for gauging team performance and productivity, but it should be used in conjunction with other project management techniques and continuous improvement practices to ensure successful project delivery.

If the product owner has highlighted performance issues with the released features during an iteration demonstration, it is important to address these issues as soon as possible.
The first step is to prioritize the issues based on their severity and impact on the usability of the product. If the issues are critical and render the released features unusable, it may be necessary to roll back the iteration and address the issues before moving forward. If the issues are less severe, it may be possible to continue with the iteration while working on resolving the issues. It is important to communicate the situation to the development team and make sure they understand the impact of the performance issues on the usability of the product. The team can then work together to identify the root cause of the performance issues and come up with a plan to address them.
It is also important to involve the product owner in the process and keep them updated on the progress of resolving the performance issues. This will help to build trust and ensure that the product owner is aware of any potential delays or impacts on the product roadmap. Overall, addressing performance issues during an iteration demonstration requires a collaborative approach and a focus on resolving the issues as quickly as possible to ensure the usability of the product is not impacted.

solve the following recurrences using the iterative method, aka the method of substitution. you must show your work, otherwise you will lose points. assume a base case of t (1)
To solve a recurrence relation using the iterative method or the method of substitution, we need to first assume a solution and then substitute it into the recurrence relation to see if it works.
If it does not work, we modify our assumption and repeat the process until we arrive at a solution. Let's consider the following recurrence relation: T(n) = 2T(n/2) + n Assuming a base case of T(1), we can write the following sequence of values:
T(n) = 2T(n/2) + n
= 2[2T(n/4) + n/2] + n
= 2^2 T(n/2^2) + 2n
= 2^2 [2T(n/2^3) + n/2^2] + 2n
= 2^3 T(n/2^3) + 3n
= ...
= 2^k T(n/2^k) + kn
We can see that this sequence terminates when n/2^k = 1, or k = log_2 n. Therefore, we have: T(n) = 2^log_2 n T(1) + n log_2 n = nT(1) + n log_2 n Thus, the solution to the recurrence relation T(n) = 2T(n/2) + n using the iterative method or the method of substitution is T(n) = nT(1) + n log_2 n.

All interactions between the stakeholders and the Development Team should be through the Product Owner.
Thus, the success of this approach relies on the Product Owner's ability to effectively manage the product backlog and prioritize stakeholder needs in a way that balances business value with technical feasibility.
The Scrum framework places a significant emphasis on the role of the Product Owner in serving as the primary point of contact between the Development Team and the stakeholders. This approach is based on the principle that having a single person responsible for prioritizing and managing the product backlog ensures a clear and consistent direction for the development effort.
By channeling all interactions through the Product Owner, the Development Team is able to maintain a focus on their primary responsibility of delivering the highest possible value in each sprint. This means that stakeholders are encouraged to communicate their needs and feedback to the Product Owner, who then prioritizes these items based on their importance and impact on the product's success.In practice, this approach can result in increased efficiency and productivity, as well as improved transparency and collaboration between the various parties involved in the development process. However, it is important to note that the Product Owner is not expected to act as a gatekeeper or filter for all stakeholder input, but rather as a facilitator for effective communication and decision-making.Ultimately, the success of this approach relies on the Product Owner's ability to effectively manage the product backlog and prioritize stakeholder needs in a way that balances business value with technical feasibility. By doing so, they can help ensure that the Development Team is able to focus on delivering high-quality, valuable software that meets the needs of both the stakeholders and the end-users.Know more about the product backlog
