An Embedded System is a special-purpose computer system designed to perform dedicated functions or tasks within a larger mechanical or electrical system. Unlike general-purpose computers, embedded systems are optimized for performance, reliability, and efficiency in specific applications.

Communication Protocols in Embedded Systems

• I2C / SPI – For communication between chips and sensors.

• UART / USART – Serial communication.

• CAN – Widely used in automotive.

• Ethernet / Wi-Fi / BLE – Networking.

• USB – Device connection to PCs or peripherals.
