Mapped Learning Podcast

Mapped Learning has always been built on a simple idea: Clear, calm, ad‑free education that anyone can access, no matter their background or income. Everything I create — every video, every article, every walkthrough — is free, and most importantly it will stay that way. But I also want to be transparent about what donations support, why they matter, and how they help this project grow. Donations...

⭐ Certifications, Degrees, Experience — and Why Quality Beats Quantity Every Time Read the article below, or listen to the podcast if you want to hear me tell the full story in my own voice. Breaking into tech — or growing within it — is confusing. Everyone has an opinion about certifications, degrees, and experience, and most of those opinions contradict each other. Some people swear by certific...

Staying Safe Online: How to Verify What You Click — Part 1 (Desktop Edition) By Jonathan — Mapped Learning Online safety isn’t about fear. It’s about clarity. Every day, people click links in emails, messages, and websites without realizing how easy it is for attackers to imitate something familiar. A login page that looks identical. A sender name that seems legitimate. A URL that’s almost right....

IPv4 Subnetting, Part 2 — The Magic Number, the Octet of Interest, and the Subnetting Workflow Subnetting is one of the most important skills in networking — and one of the most intimidating when you’re first learning it. In Part 1 of this series, you learned the foundations: CIDR notation, borrowing bits, and how AND‑ing determines network boundaries. In Part 2, we take those ideas and turn them...

Subnetting has a reputation for being one of the most confusing topics in networking — but that’s usually because people jump straight into the math without understanding the ideas underneath it. In Mapped Learning, we do things differently. Before we calculate anything, we build the mental tools that make subnetting make sense. Today’s lesson is IPv4 Subnetting, Part 1 , and it focuses entirely o...

Today’s lesson is based on a question from a friend:“Would you upgrade your modem from an XB7 from Xfinity? I was curious if there was a better, more secure option or if it was good enough as-is since it’s a Cisco modem but it only seems to have WEP2 security.” Great question! If you would like to ask your own question for me to answer, feel free to ask here: Mapped Learning Chat To answer that qu...

This video is a clear, beginner‑friendly walkthrough of the CIA Triad , the foundational model that shapes every cybersecurity decision.

In the video, I explain what the CIA Triad a...

Summary : IPv4 is a 32‑bit addressing system made of four 8‑bit octets, with binary values determining ranges, classes, and subnet masks. This lesson walks through binary powers, classful addressing, default masks, and CIDR notation using clear examples like 192.168.1.15/24.

Welcome to the About Me video — the story behind who I am, where I come from, and why I created Mapped Learning. My path through education has been long, intentional, and built on curiosity. I started at Heald College, earning four Associate’s degrees in Applied Sciences: Electronics and Computer Repair, Cisco Networking, Microsoft Networking, and Network and Systems Administration. From there, I...
