What two things can a vehicle computer actually perform (output)?

The vehicle computer can perform the action of turning something on or off, which is crucial for managing various systems within the vehicle. This capability enables the computer to control components like fuel injectors, ignition coils, relays, and other electrical devices throughout the vehicle. By exerting control over these components, the vehicle computer can effectively manage operations such as the starting and stopping of the engine, activating lights, or engaging the air conditioning system, facilitating the vehicle's overall functionality.

While other functions like storing and processing information or calculating values are important roles of vehicle computers, they primarily serve the purpose of managing outputs and actions within the vehicle systems.
