Source coding and channel coding are two different processes in digital modulation. Source coding is the process of compressing the data to reduce the amount of information that needs to be transmitted. It aims to remove redundancy and irrelevant information from the source data. On the other hand, channel coding is the process of adding redundancy to the data before transmission in order to make it more resilient to errors that may occur during transmission. It aims to protect the data from noise and interference in the communication channel. In summary, source coding reduces the amount of data to be transmitted, while channel coding adds redundancy to protect the data during transmission. **

The coding strand, also known as the sense strand, is the DNA strand that has the same sequence as the mRNA that is transcribed from it. This means that the coding strand has the same sequence as the resulting protein. On the other hand, the non-coding strand, also known as the template strand, is the DNA strand that is used as a template for the synthesis of mRNA during transcription. It has a complementary sequence to the mRNA and does not directly code for the protein. **

Huffman coding is a method used for lossless data compression, where variable-length codes are assigned to different characters based on their frequencies in the input data. This technique ensures that more frequent characters are assigned shorter codes, while less frequent characters are assigned longer codes, resulting in overall compression of the data. Huffman coding is widely used in various applications, such as file compression algorithms and data transmission protocols, to reduce the size of data without losing any information. **

Online commerce refers to the buying and selling of goods and services over the internet, while retail commerce refers to the traditional brick-and-mortar stores where customers can physically visit and make purchases. Online commerce offers the convenience of shopping from anywhere at any time, while retail commerce provides the opportunity for customers to see, touch, and try products before making a purchase. Online commerce often involves lower overhead costs and can reach a wider audience, while retail commerce provides a more personalized and immediate shopping experience. **
