History of Modern Technology: Cards, Codes, And Courage | Technology Education
professorjrod@gmail.com A census solved with cardboard, a company remade by a $5 billion gamble, and a tiny firmware layer that cracked open the PC market—this is the human story behind how computing became a platform, not a product. We go from Hermann Hollerith’s 1890 insight to IBM’s sales-first system that taught the world to think in fields and records, and then to the cultural and ethical crosscurrents that come with scale. Those punched holes didn’t just count people; they trained gener...

The One Hundred Episode
professorjrod@gmail.com The mic feels heavier at 100—not from gear, but from history. We started with a doctoral dare, a $40 class, and a shaky first recording. We built a library that helped learners pass A+, Network+, and Security+ while connecting the dots between hardware, operating systems, storage, networking, and the human choices behind every device and policy. Along the way, our mission sharpened: pair skill with story, prioritize curiosity over checkboxes, and keep ethics at the cen...

A Plus+ Fundamentals: Network Language, Decoded | IT Skills Development Chapter 6
professorjrod@gmail.com Ever wish the network would just explain itself? We walk through the real language of connectivity—how links come alive, how packets choose their paths, and how a few core ideas unlock routers, firewalls, addressing, and the exam questions that test them. It starts with the wire (and the air): DSL over copper, cable scaling with DOCSIS, fiber to an ONT at your home, and why fixed wireless, satellite, and 5G fill coverage gaps with very different tradeoffs in speed and ...

professorjrod@gmail.com What if your “all-in-one” router is doing too much—and your Wi‑Fi “speed” isn’t the real bottleneck? We pull back the rack door and trace the digital bloodstream from SOHO setups to enterprise backbones, translating jargon into choices you can actually make. Starting with LANs, WANs, WLANs, and SANs, we map how scope changes design, cost, and risk, then contrast the convenience of a home gateway with the clarity of dedicated roles—routers, switches, firewalls, and load...

History of Modern Technology: Pocket Power: The USB Story | Technology Education
professorjrod@gmail.com A tiny stick changed how we move information—and how attackers move too. We pull back the curtain on the USB flash drive’s quiet takeover: why floppies and CD-Rs failed us, how flash memory and USB converged, and which teams across Singapore, Israel, and China raced to ship the first pocket drive that actually worked. From early 8 MB models that cost a small fortune to today’s terabyte dual‑connector rockets, the arc is a crash course in convenience beating complexity....

professorjrod@gmail.com A dead PC at the worst moment is a gut punch—unless you have a roadmap. We walk through the exact thinking that turns “no lights, no fans, no display” into a calm, step‑by‑step recovery, starting where every system truly begins: firmware. BIOS and UEFI aren’t trivia; they decide how your machine discovers drives, validates bootloaders, and applies security like Secure Boot and TPM. That’s why a simple post‑update check of boot order, storage mode, and firmware toggles ...

professorjrod@gmail.com Storage didn’t just get bigger; it got personal. We rewind to the late ’90s and early 2000s to unpack the clash between Iomega’s Zip drive and the laser-lit world of the CD—two formats that taught a generation how to back up, carry, and truly own their data. From the pain of 30‑floppy installs to the thrill of dropping a 700 MB burn into a jewel case, we dig into what made each medium take off, where they stumbled, and why their lessons still shape how we save files to...
