Just finished watching the match between Mexico and South Africa I'm still sitting on the couch as I'm typing this let's dive in as I still post all I've learnt so far.. Chapter 3: Types of Networks One of the things I learned early in my cybersecurity journey at Bloomy Technology was that not all networks are the same. Before then, I thought a network was just "internet" and nothing more. As I progressed through the networking module, I learned that networks are often grouped based on their size and coverage area. The three that stood out to me were: 🔹 LAN (Local Area Network) A LAN connects devices within a small area such as a home, school, office, or cyber café. At the time, I realized that whenever my phone and laptop were connected to the same Wi-Fi, they were already part of a LAN. 🔹 MAN (Metropolitan Area Network) A MAN covers a larger area, usually a city. An example would be an organization connecting multiple branches within the same city. 🔹 WAN (Wide Area Network) A WAN covers a much larger geographical area, connecting networks across states, countries, or continents. The Internet itself is the most common example of a WAN. What fascinated me back then was realizing that the Internet isn't one giant network. It's actually a collection of smaller networks connected together. Looking back now, this may seem basic, but understanding these concepts helped me appreciate why networking is often considered the foundation of cybersecurity. You can't effectively secure a network if you don't understand how it works. This was one of the lessons that stuck with me from my first networking classes. #CyberSecurity #Networking #NetworkPlus #LearningInPublic #CyberSec @ireteeh @johncvillanueva @_DeejustDee

Static Routing = manually telling routers where to send traffic 🌐 • Uses routing tables & next hops • Best for small or stub networks • No dynamic routing overhead • More secure but less scalable • Changes require manual updates #Networking #Routing #NetworkPlus

Chapter 1: Introduction to Networking The first thing I learned when I started my cybersecurity journey at Bloomy Technology was Networking. At the time, I used the internet every day but never stopped to think about what actually happens when I send a message, open a website, watch a video, or download a file. Networking taught me that computers don't magically communicate with each other. They follow rules. They use addresses. They send and receive data through devices and protocols designed to make communication possible. One of the simplest ways I now explain networking is this: Imagine sending a letter to a friend. You need: 📍 An address 📍 A way to deliver it 📍 Rules that ensure it gets to the right person Computer networks work in a similar way. Every device has an address, data travels through different paths, and communication follows specific rules called protocols. Before cybersecurity can protect a network, you first need to understand how that network works. That's why networking became the foundation of everything else I learned afterward. Although I didn't know why they started with this instead of first introducing us to the topic itself, cyber Security.... While typing this I'm looking at the notes I made during the first class.. I'll be using the notes throughout my journey So what I post is exactly what I got From the class A question for those further along in cybersecurity: What's one networking concept that completely changed the way you understand the internet? #CyberSecurity #Networking #NetworkPlus #LearningInPublic #CyberSec @ireteeh @johncvillanueva
