CRC Using Polynomial & Checksum (Complementary) in Bangla | Error Detection | Data Communication

n this video, I explain Error Detection techniques in Bangla, focusing on CRC using Polynomial representation and Checksum, based on Week-11, Lesson-1 & 2 of Data Communication (CSE 225/233). This lecture helps you understand how cyclic codes work using polynomials, how CRC division is performed, and how Checksum is used in real networking systems like the Internet (Network & Transport layer). 🔹 Topics Covered in This Video: Polynomial representation of binary data CRC using polynomial division Standard Generator Polynomials Why CRC is reliable for error detection What is Checksum Concept of Checksum (Sender & Receiver) Complementary Checksum procedure Checksum algorithm Numerical examples of Checksum 🎓 Suitable for: CSE, EEE & Diploma in Engineering students studying Data Communication (CSE 225/233) or Computer Networks. crc bangla checksum bangla crc polynomial bangla error detection bangla data communication bangla computer network bangla cse 225 bangla crc division bangla generator polynomial bangla checksum algorithm bangla networking bangla tutorial digital communication bangla
