This video explains the method of converting a decimal number to a binary number. Many solved examples are given here and also two exercises which you can attempt on your own and then check the answers. I have also discussed the concept of LSB (least significant bit) and MSB (most significant bit), and also least significant digit (LSD) and most significant digit (MSD). This topic is important for following courses: class 11 and 12 computer science of all state boards, class 11 and 12 physics, BSc Computer science, BSc IT, MCA (Masters degree in Computer Applications), BTech, BE (First Year), and many competitive examinations.
