STP prevents network loops & keeps switches stable 🌐 • Detects and blocks looped paths • Creates a loop-free topology • Restores connectivity if a link fails • RSTP provides much faster recovery ⚡ #Networking #STP #NetworkPlus

Network performance depends on proper interface configuration ⚡ • Match speed & duplex settings • Correct IP, gateway & DNS are essential • Link Aggregation boosts bandwidth • MTU & Jumbo Frames improve efficiency #Networking #Ethernet #NetworkPlus

VLANs help organize and secure networks 🌐 • Separate broadcast domains on one switch • 802.1Q trunking carries multiple VLANs • Layer 3 switches enable inter-VLAN routing • Voice & data traffic can stay isolated #Networking #VLAN #NetworkPlus

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

NAT helps solve IPv4 exhaustion 🌐 • Converts private IPs to public IPs • Lets devices access the internet securely • PAT/NAT Overload allows many devices to share one public IP #Networking #NAT #NetworkPlus

Routing keeps networks connected 🌐 • Routing tables decide packet paths • Administrative Distance picks trusted routes • Metrics choose the fastest/best path • FHRP adds gateway redundancy with VIPs • Subinterfaces allow routing between VLANs #Routing #NetworkPlus

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 2: What Exactly Is a Network? When I first heard the word "network," I thought it sounded complicated. It turns out the idea is actually simple. A network is just two or more devices connected together so they can communicate and share resources. For example: 📱 Your phone connected to your home Wi-Fi 💻 Your laptop connected to a printer 🏢 Computers connected within an office All of these are examples of networks. What surprised me was that the Internet itself is simply a massive network made up of millions of smaller networks connected together. Without networks: ❌ No WhatsApp messages ❌ No YouTube videos ❌ No Google searches ❌ No online banking Understanding networks is important because cybersecurity professionals spend a lot of time protecting them. You can't secure something you don't understand. That's one of the biggest lessons networking taught me. Next, I'll share the different types of networks and where we use them in everyday life. #CyberSecurity #Networking #NetworkPlus #LearningInPublic @ireteeh @_DeejustDee @johncvillanueva

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
