As we delve into the realm of internet infrastructure and its critical role in fostering innovations like web applications, it becomes increasingly essential for product management for beginners to attain a foundational understanding of the online world. This knowledge not only empowers product managers to devise robust digital strategies but also prepares them for challenging product management interviews.

Understanding the Network of Networks

At its core, the internet is a vast mosaic of interconnected networks functioning seamlessly to connect billions of users worldwide. Whether it’s a network serving just four individuals or one linking four billion, the internet’s underlying principles remain consistent. This seamless connectivity likens to a system of roads and highways, where information travels across vast distances from one computer to another.

The Role of IP Addresses and DNS Servers

IP addresses, like home addresses for postal deliveries, uniquely identify devices on the internet. The transition from IPv4 to IPv6 supports the expanding global network amid digital device proliferation.

To make the internet user-friendly, DNS servers act as the internet’s phonebook, translating domain names like ‘’ into IP addresses that computers understand. These servers maintain this crucial mapping, allowing for the efficient location and retrieval of information across the globe.

Decoding TCP/IP: The Language of the Internet

The TCP/IP protocols are the linchpins of internet communication, ensuring that data is reliably transferred between devices over this vast network. Breaking down large files into manageable packets allows for efficient data transport. Consider these packets as letters sent via post, each tagged with a unique sequence and metadata to reach its destination accurately.

The Crucial Handshake Between TCP and IP

While IP takes charge of directing packets to their destinations based on addresses, TCP oversees the orderly reassembly of these packets at the receiving end. It’s a digital symphony of sending and receiving information, orchestrated by integral rules for internet robustness and reliability.

ISP: The Connective Backbone

Internet Service Providers (ISPs) play an often-overlooked yet vital role. They lay down the physical and virtual pathways that empower us to access the vast expanse of the internet. Their services form the backbone of our daily online experiences, from streaming videos to conducting virtual meetings.

Why Should Product Managers Care?

In the domain of product management, a deep-seated comprehension of these technologies is non-negotiable. Innovating in digital requires understanding internet mechanics, from web apps to governing protocols. Product managers need a broad understanding to create products for dynamic online environments.

Conclusion: Bridging Knowledge with Application

Thriving as a product manager requires understanding internet basics, user-centric design, and market analysis. For product management success, understand the internet’s infrastructure, a reservoir of potential for digital innovation.

Flipped Classroom


Our learners learn by discussing and debating on real-world problems and are actively involved in the solution design process.

Conventional classroom

Sage on Stage

  • A teacher shares the knowledge via live presentations
  • Teachers are at the center of the learning and considered sage on stage
  • Knowledge transfer is one-way and the focus is on knowledge retention
  • Learners don’t get to discuss their ideas or opinions in the class
  • Hence, most learners are unable to apply these concepts in their everyday work life
  • Great for scenarios, where knowledge acquisition and retention is the only focus

Flipped classroom

Guide on side

  • Learners are the center of the universe
  • Classes are meant for healthy discussions and debates on topics
  • Learners go through the material on their own provided by the mentors
  • Mentors work as guide on the side, with the learners
  • Learners develop skills on problem solving, critical thinking and self-learning – the 21st century skills that employers look for
  • Great for scenarios where application skills matter
  • 21st century skills require guide on the side. Simply acquiring knowledge is worthless now.
