As a student learning computer science and software development, you embark on a journey filled with countless concepts, tools, and technologies. However, amidst all these terms and information, it’s easy to lose sight of the real purpose of learning: understanding how things work and why they matter. Many learners fall into the trap of accumulating knowledge without a clear sense of its practical function. Instead of learning for the sake of learning, the focus should be on grasping concepts because they serve a purpose. Another issue is the tendency to overlook certain fundamental concepts, thinking they’re unimportant or less relevant. But as you progress, these gaps in understanding start to form knowledge voids that can hinder deeper learning and problem-solving. This blog is here to fill those gaps—to explore the "between-the-lines" knowledge that often goes unnoticed but plays a crucial role in mastering technology. I break down why these concepts matter, even when they don’t seem significant at first glance.
