Computing Architectures was created for anyone who wants to understand computers beyond the surface. The site explores everything from core operating systems Windows, macOS, Linux to building desktops, upgrading components, troubleshooting issues, and navigating enterprise IT challenges. It also dives into gaming and performance, optimization techniques, networking, and the growing ecosystem of software and open source tools.
The purpose is simple: make complex computing concepts understandable without losing their depth. Articles are written with clarity in mind, offering explanations that students, hobbyists, professionals, and IT administrators can all put into practice. This is not a place for hype or marketing it’s a place to find honest, well researched guidance that helps readers make better decisions, whether they’re installing a new SSD, setting up a network, or managing enterprise systems.
At its core, Computing Architectures is about empowerment. By breaking down the “why” behind technology, the site equips readers to troubleshoot with confidence, optimize with purpose, and embrace the fast changing landscape of computing with curiosity instead of confusion.
It’s built on Harold’s lifelong passion for both technology and teaching and designed to be a trusted resource for anyone who wants to truly understand the architecture that powers our digital world.
About Harold Trujillo
Harold Trujillo grew up in Albuquerque, New Mexico, in a home where technology and curiosity went hand in hand. His mother taught physics at the local high school. While his father worked as a hardware engineer in telecommunications. The family garage was less a place for cars and more a workshop filled with old circuit boards, wires, and half assembled computers. It was there that Harold first discovered the thrill of pulling machines apart. Experimenting with makeshift networks, and writing code to control small sensors.
That early fascination guided him to Arizona State University, where he earned a Bachelor of Science in Computer Engineering. During college, Harold worked in the systems lab, helping graduate students run experiments in parallel computing. It was hands on work that gave him an appreciation for both the elegance and complexity of modern computing. After graduation, he joined a midsized data infrastructure company as a systems architect. For the next several years, he designed distributed systems, optimized performance across enterprise platforms. And learned how hardware and software decisions ripple out into real world results.
Alongside his technical career, Harold always sought ways to teach. He wrote internal guides for colleagues, mentored junior engineers, and spoke at local tech meetups. What he noticed, again and again, was a gap: everyday computer users, hobbyists, and even new IT professionals often struggled to find explanations that were practical without being shallow, or detailed without being overwhelming. That gap became the seed for Computing Architectures.
In 2025, Harold launched Computing Architectures as a space where technology could be explained clearly and applied directly. Today, the blog covers everything from operating systems like Windows, macOS, and Linux to hardware upgrades, gaming performance, networking, enterprise IT, troubleshooting, and open source software. Each article reflects Harold’s belief that good computing knowledge should be accessible to anyone willing to learn. His mission is simple: to give readers the confidence to not just use computers, but to truly understand how they work.
