Through a number of methods, an embedded system protocol guarantees dependable communication. Data transmission mistakes are found and fixed via error detection and correction techniques like checksums and CRC (Cyclic Redundancy Check). Data interchange between devices is coordinated by handshaking protocols, which guarantee that data is transferred and received in a systematic manner. Data transmission speeds are regulated via flow control techniques, such as XON/XOFF, to avoid buffer overflow. Retransmission techniques are also used by protocols such as TCP/IP to restore dropped packets and preserve data integrity.

An embedded system course provides both theoretical knowledge and practical abilities for students who wish to become experts in this subject. It includes important topics including microcontroller programming, real-time operating systems, and numerous communication protocols.
