Since no channel is perfectly silent, we need "Coding." This involves adding structured redundancy to the data so the receiver can detect and fix errors.
This is the process of compressing data. By understanding the probability of certain bits appearing, we can represent common data with fewer bits (like Huffman Coding), ensuring we don't waste "bandwidth" on redundant information. 2.

Digital copies were non-existent. The departmental server held a corrupted PDF that jumped from page 68 to 70. Legend among the PhD students said that page 69 contained a handwritten note from a former researcher—a shortcut through the complex math of Reed-Solomon codes that felt more like magic than logic.
