eMMC
eMMC (embedded Multi-Media Card) is a type of storage technology commonly used in automotive infotainment systems, like the memory card in your phone but built into the car's system. It's basically a small storage device that holds important information like navigation maps, entertainment apps, and system software. When you see this term in resumes, it usually means the person has experience working with car entertainment systems' storage and memory components. Think of it like a built-in USB drive that's specifically designed for vehicles and other embedded systems.
