This lesson covers data compression — reducing the size of files to save storage space and reduce transmission time. You need to understand lossy and lossless compression, and specific algorithms: Run-Length Encoding (RLE), Huffman coding, and dictionary encoding (LZW).
| Benefit | Explanation |
|---|---|
| Reduced storage | Smaller files use less disk space |
| Faster transmission | Smaller files transfer more quickly over networks |
| Lower bandwidth usage | Less data to send = less network capacity needed |
| Cost savings | Less storage and bandwidth = lower costs |
