Embedded systems are specialized computing systems that perform dedicated functions within larger mechanical or electrical systems. The key components of embedded systems include:

Microcontroller/Microprocessor: The brain of the system, responsible for executing instructions and controlling the overall operation. Microcontrollers often integrate CPU, memory, and peripherals on a single chip.

Memory: Used for storing code, data, and intermediate processing results. It typically includes both RAM (for temporary storage) and ROM/Flash memory (for permanent storage of firmware).

Input/Output Interfaces: Facilitate communication between the embedded system and external devices. These interfaces can include GPIO (General Purpose Input/Output) pins, serial ports (e.g., UART, SPI, I2C), and specialized interfaces like USB or Ethernet.

Power Supply: Provides the necessary power to the system. Embedded systems often operate on low power and may include power management features to extend battery life.

Sensors and Actuators: Sensors collect data from the environment (e.g., temperature, pressure), while actuators convert electrical signals into physical actions (e.g., motor movements).

Software/Firmware: The embedded code that runs on the microcontroller, handling tasks like data processing, communication, and control functions.

Understanding these components is crucial for designing and optimizing embedded systems. For those seeking to gain expertise in this field, enrolling in an embedded system certification course can be highly beneficial.
