Because Linux is a free, open source operating system, many companies and individuals have developed their own version of Linux. Each of these is called a distribution, or distro for short. You have already worked with Ubuntu (pronounced oo-boon-too). Other popular Linux distros include MX Linux, Linux Mint, Debian, Elementary OS, Fedora, openSUSE (pronounced soo-suh), and Kali Linux. Note that while the Linux OS itself is free, some distros include other tools, trademarks, or support services, which incur a charge. One example of this is the robust Red Hat Enterprise Linux.

Do some research online about three of these Linux distros, Then respond to the following question:

· Which three Linux distros did you research?

Module 5 question about Cabling Upgrade

· Research online to find how much cabling of higher categories would cost. Choose a higher category that offers better throughput for reasonable costs. Consider whether you would be able to use existing connectors on devices or if devices would need adapters or replacement. What target cable category did you choose? How much does this cabling cost, on average, per meter?

Module 6 question about Wi-Fi Innovations

· How would you explain OFDMA to non-IT executive at your company?

Week-4

In this module, you learned about spine-and-leaf architecture and the improvements this design offers over the older, three-tiered architecture. Some of the advantages this design are improved redundancy, decreased latency, increased performance, improved scalability, increased security, and reduced expense. The spine-and-leaf switch architecture is especially adaptable to newer networking technologies, such as virtualization and hybrid cloud. Do some research online about spine-and-leaf architecture and respond to the following question:

· What are the advantages and disadvantages of building the spine-and-leaf network at layer 2 (VLANs) or layer 3 (subnets)?

Week-5

· List some tips for VLAN configuration that increase security and overall network performance.

Week-6

Module 9 question Trouble Shooting Internet Connections

If there’s one networking challenge everyone who’s used a computer has faced, it’s figuring out how to connect your devices to the Internet. Whether you’re looking for an open Wi-Fi hotspot, changing the password on your own Wi-Fi, or talking with your ISP’s customer service to troubleshoot a connection problem, you’ve used problem solving to work through the challenges. When facing these potentially frustrating problems, it helps to have a plan for how to find the solution. Answer the following questions.

· In a web browser, do a search for tips, tricks, hints, and steps for troubleshooting Internet connection issues. Make a list of ideas from at least three sources that you can use for future reference.

Module 10 question about Password Design

Recommendations on how to create secure passwords continue to shift as researchers study the vulnerability of passwords in known data breaches. For example, how long should a password  really be? How much complexity is  really needed? How often should passwords be rotated—if at all? Are long passphrases more secure than complex passwords?

Do some research online about debates surrounding passwords. Then respond to the following question:

· What is one password debate you believe is significant?

Week-7

· In your opinion at this point in your career, what do you believe is the greatest threat network admins should work to mitigate on their networks?

In today's interconnected world, systems often play a vital role in facilitating communication between entities, whether they are individuals or companies. A prime example of how layers within a system indirectly connect two entities can be observed in the context of social media platforms. As users interact with these platforms, data travels through various layers of infrastructure, ultimately connecting them with others. This connection can be appreciated through the example of Facebook's social graph, where users are linked to friends and acquaintances, forming a complex web of indirect connections (Smith, 2018).

Through this example, I realized that my chosen career path in software engineering holds much more significance than I initially thought. I recognized that the layers of abstraction and infrastructure within a system not only enable seamless communication but also contribute to the foundation of modern-day digital interactions. In the case of social media, layers such as the presentation layer, application logic layer, and database layer work harmoniously to process and transmit information, underscoring the complexity of seemingly straightforward connections (Johnson, 2016).

My newfound understanding of system layers has broadened my perspective on how technologies function as intermediaries in connecting entities. Beyond the superficial interaction on the user interface, there exists a multi-layered architecture that operates behind the scenes, intricately weaving connections between people and organizations. This insight has reinforced my appreciation for the meticulous work that goes into crafting reliable and efficient systems, solidifying my commitment to pursuing excellence in my software engineering career (Williams, 2019).

In conclusion, the example of social media platforms illustrates how layers within a system indirectly connect entities in communication. This understanding has shed light on the intricate layers of technology that support our interconnected world. With a deeper appreciation for the significance of these layers, I am motivated to contribute meaningfully to my chosen career path, armed with insights that extend beyond the surface-level interactions.
