Every Popular Protocol Explained in 17 minutes
Ever wondered how devices actually communicate from the chips on a circuit board to the servers across the globe? In this video I break down 14 of the most essential hardware and network protocols from UART and SPI to TCP and HTTPS so you can finally understand the full stack of how data moves through our world.
This comprehensive guide is split into two halves: Hardware Protocols where we look at how microcontrollers talk to sensors and peripherals and Network Protocols where we dive into the foundation of the internet and real time data exchange. Whether you are an electronics hobbyist a computer science student or a developer this 17 minute breakdown explains the fundamentals in one place.
