Channel Title: Craig'n'Dave Channel Description: The Craig’n’Dave YouTube channel provides students and teachers with ad-free videos covering the knowledge required for every bullet point of the GCSE and A level specification for Computer Science. Unlike other channels, these are not generic computer science videos. They are bespoke to the specification with different videos for each exam board, AQA, Cambridge, OCR and Pearson Edexcel. Ideal for flipped classroom teaching, videos allow students to be prepared ahead of their lesson by learning the subject content at home. A handy “take notes” icon on some slides prompts the student to pause the video and take Cornell notes. This scaffolding is removed at A Level to prepare students for university. Narrated by teachers with over twenty-five years’ experience in secondary classrooms, Craig and Dave both have a degree in computer science, experience in the industry, and an expert knowledge of the subject and pedagogy. <video> Why can't we just stick RAM on the CPU? Description: Why can't we just stick RAM on the CPU? 🤔 Ever wondered why we can't just stick RAM directly onto the CPU for faster speeds and zero latency? It sounds like the ultimate upgrade, but there’s more to it than meets the eye! The Lesson Hacker looks into why combining RAM and the CPU isn’t as simple as it seems. From the technical differences between CPUs and DRAM to the speed limitations that hold us back, we break it all down in a fun and easy-to-understand way. 🚀 We also explore the role of SRAM as a faster alternative to DRAM and why, despite its speed, it’s just too costly for most of us to use in every CPU. So, if you're curious about the tech behind your computer and why things are designed the way they are, hit play and let's get into it! 🎥 🔔 Don’t forget to like, comment, and subscribe for more tech drama and insights from Craig’n’Dave.

The Hidden Price Behind Your Chip! Ever wondered how much it actually costs to build a CPU? In this video, the Craig 'n' Dave lesson Hacker takes you through the insanely complex and costly process of creating the CPUs we rely on daily, from atomic-scale transistors to the cutting-edge brainpower behind it all. It’s not just about silicon and a bit of heat—it's a high-stakes game of precision, technology, and eye-watering costs. From the £8,000+ price tag for a single usable silicon wafer to the mind-blowing £16 billion price of building a state-of-the-art factory (a "fab"), the cost of making a CPU is nothing short of jaw-dropping! Hit play to see just how much goes into building the tiny chip that powers your tech! 🔔 Don’t forget to like, comment, and subscribe for more tech drama and insights from Craig’n’Dave.

We also take a look at the history of computing and explain why binary has stood the test of time, while alternatives like ternary (Base-3) were eventually left behind. 🔔 Don’t forget to like, comment, and subscribe for more tech drama and insights from Craig’n’Dave.
