👋 Hi! I’m John McNae. I’m a passionate IT professional with a deep curiosity about how technology shapes our world. With years of hands-on experience in hardware, software, and networking, I love turning complex technical concepts into clear, practical knowledge. Driven by a constant desire to learn and share, I created this space to collect and organize valuable insights about information technology — from essential definitions to detailed how-to guides. My goal is simple: to make tech understanding accessible to everyone, whether you’re an experienced professional or just beginning your digital journey.
