Week 7

Key Learnings:

This week, I learned about encoding digital data into both digital and analogue signals, and the differences between IPv4 and IPv6. Understanding these concepts is crucial for grasping how data is transmitted across networks and how IP addressing supports the vast number of connected devices today.

Personal Insights:

These new learnings changed my perspective on how networks handle data. I realized how IPv6 solves the issue of limited IP addresses, and I gained a clearer understanding of the importance of encoding methods in communication systems.

Application of Knowledge:

In a workshop, I discussed the benefits of IPv6 over IPv4 with my peers, particularly its larger address space. Additionally, I applied my understanding of DNS and ARP during an assignment on address resolution.

Challenges Faced:

I found it difficult to understand routing protocols like distance vector vs. link state. Reviewing tutorials and discussing with peers helped me overcome this by breaking down the concepts.

Future Goals:

Next week, I aim to deepen my understanding of TCP and UDP by analyzing packet data and comparing their use in real-world scenarios.

Week 8

Key Learnings:

This week, I learned about Media Access Control (MAC) for Ethernet and WLAN, and how Ethernet switches use forwarding tables to direct traffic. Understanding MAC protocols helps me see how data is efficiently managed and transmitted over networks, ensuring smooth communication across devices.

Personal Insights:

Learning about MAC and Ethernet forwarding tables enhanced my understanding of how network devices avoid collisions and how data is routed within a network. It challenged my previous view that data transmission was more chaotic and less structured.

Application of Knowledge:

In an assignment, I applied my knowledge of WLAN setups and service sets, exploring how channels are used to avoid interference. I also discussed with peers how large organizations structure their LANs and WANs for better scalability.

Challenges Faced:

I found it challenging to grasp how Ethernet switches build and maintain forwarding tables. Reviewing examples and diagrams helped clarify this process.

Future Goals:

Next week, I aim to focus on how routing works between LANs and WANs, particularly how organizations manage traffic at a larger scale.

Week 9

Key Learnings:

This week, I explored the structure of the Internet, including Autonomous Systems, Internet Exchange Points (IXPs), and Content Delivery Networks (CDNs). Understanding these components helps me grasp how the Internet is organized to ensure efficient and reliable data transmission across global networks.

Personal Insights:

Learning about the decentralized nature of the Internet and its reliance on open standards has highlighted the strengths in its design, such as resilience and scalability. However, I also realized the vulnerabilities, such as threats from cyberattacks and the challenges of maintaining control over such a vast system.

Application of Knowledge:

In a group discussion, I used my understanding of IXPs and CDNs to explain how they improve Internet performance and reliability. I also analyzed potential future directions for Internet development, focusing on innovations in network security and infrastructure.

Challenges Faced:

I found it difficult to fully grasp the impact of decentralized design on Internet control. Studying case studies and participating in discussions helped me understand both the benefits and drawbacks of this approach.

Future Goals:

Next week, I plan to delve deeper into emerging technologies that could shape the future of the Internet, such as advancements in network protocols and the integration of AI in managing Internet infrastructure.
