An embedded system can serve several purposes: 1. Data collection, storage, and representation - Embedded systems can collect analog or digital data from external sources, store it, and present it to users. A digital camera is an example that captures images, stores them, and displays them. 2. Data communication - Embedded systems can transmit data via wired or wireless means, either digitally or through analog signals. Examples include devices that use Bluetooth, Wi-Fi, USB, or TCP/IP for communication. 3. Control - Systems with control functions contain sensors to capture environmental changes and actuators to control outputs based on sensor inputs. An air conditioner that regulates temperature is one such example.
