LZW Compression: Why Variable Encoding is Better (Fixed vs Variable Perl)

Learn how LZW compression really works with a clear step-by-step example using ABABABA. In this video, we implement LZW in Perl, starting with fixed 16-bit encoding and then moving to a more efficient variable-length approach. You’ll understand dictionary building, encoding logic, decompression, and why variable bit sizes improve compression ratios. Perfect for students and developers studying data compression algorithms. 🕒 Timestamps: 0:00 LZW Overview & Example 1:10 Fixed 16-bit Implementation in Perl 1:50 Compress Method 4:00 Decompress Method 4:50 Variable Bit Encoding (9–12 bits) 6:20 Compress Method 7:40 Decompress Method 8:20 Results Comparison 8:40 Closing DISCLAIMER: All logos and trademarks belong to their respective owners. #perl #compression #algorithm #datacompression #programming #computerscience #coding #techeducation #LZW #fixed #variable
