CAN Bus
CAN Bus (Controller Area Network Bus) is a way for different parts of a car to communicate with each other, like a computer network inside vehicles. Think of it as the nervous system of a modern car that allows various components (like the engine, brakes, and dashboard) to share information. When you see this on a resume, it means the person has experience working with this communication system that's essential in modern vehicles. It's similar to how your home internet connects different devices, but specifically designed for vehicles and industrial equipment. This technology is used not just in cars, but also in trucks, buses, and industrial machinery.
