1.Internet devices known as hubs, switches, and routers each play a specific role in networking at their respective level. Most of the time, these devices are integrated into a single device, making it prone to be mistaken that they carry out the same responsibilities. This post will discuss how each of them is different from the others in terms of various domains and the OSI model.
The first devices we are going to discuss are hubs, which belong to the Physical layer (or layer 1) of the OSI model. They forward data retrieved from the upper layers without knowing any information about where to send the data such as hardware (MAC) or logical (IP) addresses. To prevent collisions, hubs operate in a half-duplex manner, which allows each host to either transmit or receive data, but not both. This makes hubs belong to the same collision domain, defined as a physical segment of the network where collisions may occur. They also belong to only one broadcast domain, which is the logical segment of the network instructing how far the data can be transmitted. (Aaron, 2014)
Going one layer up we encounter switches, which reside in the Data Link layer (or layer 2) of the OSI model, determining the MAC address to where they need to send the data frame. They utilize the frame headers and their MAC address tables to identify the target MAC address when forwarding the frame they received from the upper layer. Switches can operate in full-duplex, and each port on a switch belongs to its own collision domain, resulting in multiple collision domains and fewer collisions. Still, however, switches belong to only one broadcast domain, just like the hubs do. This makes switches not suitable for large and scalable networks since they have no mechanism to differentiate between networks. (Aaron, 2014)
Further going one more layer up, we finally meet the last Internet device we would like to discuss – the routers. Located in the Network layer (or layer 3) of the OSI model, they are responsible for forwarding packets from one network to another. This characteristic of routers requires them to be the only Internet devices among hubs and switches that can belong to more than one broadcast domain. In addition, like switches, routers can create multiple collision domains resulting in fewer collisions since each interface on a router belongs to its own collision domain. Similar to switches each of which has MAC address tables to decide the target MAC address, each router uses a routing table to decide the next hop router and perform forwarding decisions. (Aaron, 2014)
Below is a summary of the differences between hubs, switches, and routers. Each resides in a different OSI model starting from the lowest layer and up. Hubs belong to the Physical layer, switches to the Data Link layer, and routers to the Network layer. Hubs belong to only one collision domain and one broadcast domain, whereas routers can belong to multiple collision and broadcast domains. Switches, on the other hand, can belong to multiple collision domains, but only one broadcast domain.

After this week’s reading, I have a better understanding of the breakdowns of networking devices, IP addresses, and protocols. Here is a short summary of the differences between hub, switch, and router in terms of their performance in the areas mentioned in the prompt based on my understanding. 
Hub: It’s a layer 1 device on the ISO since it has no intelligence. All devices connected to the hub share the same collision domain and it doesn’t separate the broadcast domain. It has a very high potential for collision because a signal from one port will be propagated to all – when two devices are sending signals at the same time collision happens. 
Switch: Switch recognizes the incoming and receiving MAC addresses which significantly reduces the chance for collision. Each port on the switch is considered as its own collision domain. It’s a layer 2 device on the ISO dealing with MAC addresses. Broadcast is still shared by all the ports.
Router: Router is a layer 3 device on the ISO dealing with IP addresses. I don’t think routers deal with collisions since they are on a higher layer. Each interface on a router is one collision domain. The broadcast domain is defined by each local network (Comer, D. E., 2018).

1.Assessing Cloud Architectures:
Determine whether the cloud constructiveness provides efficient resource usage by differentiating between relative resource consumption and practical resource consumption (e. g., auto-scaling, pay-as-you-go). The state should weigh the possibilities of expenditure reduction in comparison with the expenses on the on-premise structures.
Determine what aspects point to the ability to accommodate different requirements in terms of architecture. Are they easily expandable in circumstances when the workload increases and contractible under situations when it decreases?
Assess the security measures implemented by the cloud provider and consider compliance standards that the cloud provider must adhere to. Learn what measures are in place in terms of data protection and safeguards at rest and in transit.
What is the current state as measured on the availability, latency, reliability, and up-time of the architecture? Compliance with the performance needs of your applications:
Determine to what extent this architecture is compatible with what you already have in terms of on-premises resources and applications.
Virtualized Computing:
Assess how you are leveraging virtual resources available for your use. Is there any virtual machine that remains unoccupied or not in use that can be combined with others or turned off?
Supervise VM’s from the aspect of CPU utilization, amount of RAM and used storage. This is a question of determining existing constraints such as a system’s bottleneck or limited resource availability.
Discuss the current measures for securing virtual environment and the issues of Virtual Machine isolation as well as controlling the access.
Examine the cost involved in the operation and OS of virtual machines, especially in terms of licensing and workload management.
SaaS Applications:Assess whether the SaaS application has the right functionalities that can suit your business processes.
Evaluate and analyze the security measures as well as data protection standards of the SaaS provider. Make sure they meet your compliance expectations in particular wherever applicable.
The last thing you need to understand is how deeply your SaaS application is going to assimilate with your existing systems and processes.
Determine whether the chosen SaaS application meets expectations about scalability for the future growth in your business.
Think about the risks which are connected with using certain SaaS applications and its providers when using of specific SaaS applications and providers becomes essential for your company.
Pre-Implementation, Key Practices That Determine The Success Of Cloud Migration Processes: Here are some essential strategies and considerations:Clearly Define Objectives: The first step is to determine a vision that can be achieved through the cloud migration process. Whatever your goals for adoption of the cloud technology is, ensure that they are precise before venturing into it. Thus value proposal may be expressed in financial terms (e. g., cost savings, increased agility more flexibility and scalability).
Evaluate Your Existing Infrastructure: Evaluate the existing information technology environment and the applications that can be moved to cloud environment efficiently.
Choose the Right Cloud Service Model: Choose the appropriate model in the cloud service model hierarchy and one that is affordable to your firm.
Develop a Migration Strategy: Develop a clear roadmap before transferring all your workloads to the cloud so that you can know the procedures that are involved.
Security is Paramount: Security should not be overlooked during any of the stages or in executing the migration strategy. The organizations must adopt strong Information Technology security measures and apply sensitive data encryption.
Consider the cloud resources and adopt ongoing measures to maintain optimal use in relation to costs.
Perform a detailed change management analysis to identify risks and concerns to implementing new cloud systems.
2. The businesses who are responsible for adopting cloud-based solutions are the ones who are obligated to make certain that these solutions comply with all of the appropriate security standards and regulatory requirements. Laws pertaining to data privacy, regulations that are specialized to a certain industry, and recommendations for best practices in cybersecurity are all examples of these types of regulations. When you want to make sure that sensitive data is protected in a continuous manner, it is probable that you will need to implement stringent access restrictions, encryption protocols, monitoring and logging methods, and other monitoring and logging approaches. 
This is because you want to make sure that the data is safeguarded. In order to achieve successful cloud migration campaigns, it is necessary to make advantage of the expertise and support that cloud service providers have to offer (Pahl et al., 2013). This is yet another crucial approach that must be implemented. When it comes to assisting businesses with the process of migration, cloud providers typically provide their customers with a wide variety of professional services and tools to choose from. In addition to providing solutions for deployment assistance, evaluation, and planning, these services and products also provide services. Engaging with cloud providers is something that organizations should do in order to properly manage the intricacies of cloud migrations and ensure a smooth transition to the new environment. Businesses now have the ability to properly manage cloud migrations as a result of this being achievable.

The file is for one of my classmate
I have to do reflection for every course
Don’t do just paraphrase, i upload the file to let you know how is the assignment. make sure there are no similarties and plagiarism and AI. there are some the same courses in the file
there are 8 courses which are 1- Research Methods Skills Development (1.5)
2- Become a Blockchain Developer (1.5 cp)
3- Understanding and Applying Quantitative Methods in Research (1 cp)
4- Advanced Quantitative Database Design (1 cp)
5- GRS: Foundational Issues in Qualitative Research (1 cp)
6- GRS: Developing a qualitative research design (1 cp)
7- GRS: Approaches to Qualitative Data Analysis (1 cp)
8- GRS: Common Methods in Qualitative Research (1 cp)
If you read the file , by his reflection, you will understand the content for every courses
In Assignment 1B you are required to reflect on the success of that plan and give an overview of what you learned over the course of the semester.
General Guidelines
A key part of this assignment is for you to assure me that you have upskilled. To do this, your submission should as checklist have
What you planned [assignment 1A] – activity, date, credit points
What you actually did – activity, date, credit points and artefacts
a reflection of your upskilling
Your reflective essay should consist of a brief summary of what your learning intentions were for TRM, followed by an overview of how successful your plan was. In doing so you should give an indication of the course components you took and what you learned from each. You should also discuss if there were major differences between your initial plan (assignment 1A) and what you actually did. Please note that reflection is not a description of what was covered by different Modules, which could be written by anyone using a course content.
For each of the activities, include a discussion of what you learned. This might include a detail on a problem you have solved, an overview of a new technique you were exposed to or an example of some other work you completed. This could also involve the development of a toy model for you to show you took material from the course and could apply it independently, or by analysing some of your own data using a learning technique. Each of the activities MUST have an artefact of your learning (something you designed, an activity you completed, etc.)
AGAIN: Your discussion should include the full 9 cp of work that you were expected to carry out.
This is not an essay. You should consider having specific sections for each course component you studied with an introduction as to what you tried to achieve and a reflective conclusion on what you believe you gained.
Your reflection should be maximum 3000 words in length.
In Assignment 1B you are required to reflect on the success of that plan and give an overview of what you learned over the course of the semester.

You generate an enormous amount of data in your personal and professional life, oftentimes without even thinking about it. Identify a business or organization that collects data on you, and consider what those data are, what they are used for, and how they are stored.
Share the type of data that a specific business or organization collects. What specific pieces of data are collected? Discuss how the data might be stored within a database such as MySQL addressing how many tables and columns might be used to store the data so that the data is accurate and secure.
