How the Internet Actually Works
A first-principles look at the internet: how data is split into packets, how routers pass them along, and how cables and agreed rules tie networks together.
Networks and Computing
Networks and Chips
The connections and silicon underneath modern technology.
Data Centers Explained: The Buildings Behind the Cloud
What is inside a data center, from server racks to cooling and backup power, and why their electricity and water use has become a topic of public debate.
How a Computer Chip Is Made
A high-level tour of semiconductor manufacturing: silicon wafers, photolithography, etching, doping, layering, testing and packaging, and why it is so hard.
Moore Law and the Slowing Pace of Chip Progress
What Moore's observation about transistor counts actually said, why chip progress has become slower and costlier, and what approaches may carry computing forward.
Undersea Cables: The Physical Backbone of the Internet
How fiber-optic cables laid across the ocean floor carry most international data, how they are built and repaired, and what threatens them.
What 5G Is and What It Changes
A plain explanation of fifth-generation mobile networks: the radio bands, lower delay, network slicing, and realistic expectations beyond the marketing.
What the Internet Protocol Does and Why IPv6 Exists
How IP addresses label devices and route packets, why the original IPv4 address space ran short, and how IPv6 offers a vastly larger pool.
Why Graphics Processors Became Central to AI
How parallel computing and matrix math made graphics chips a natural fit for training and running neural networks, and where other accelerators come in.
Wi-Fi Explained: How Wireless Home Networks Work
How Wi-Fi turns radio waves into a home network, what the router does, what the 2.4, 5 and 6 GHz bands mean, and common causes of slow connections.
