Codebooks

A codebook is a reference guide used in data processing and communication, outlining how information is represented or encoded. It defines the set of possible symbols, codes, or instructions used to translate complex data into simpler, standardized formats for storage, transmission, or analysis. Think of it as a detailed instruction manual that ensures everyone or every system understands how to interpret the encoded data correctly. Codebooks are essential in fields like data compression, cryptography, and survey research, helping to maintain consistency and accuracy when handling large or complex datasets.
