Big-endian and little-endian describe the byte order used in computer memory for multi-byte data types. Different systems must agree on byte order to exchange data correctly, or convert formats to avoid misinterpretation.

Computational thinking enables us to solve complex problems by breaking them down into smaller parts (decomposition), recognizing patterns, and focusing on essential elements (abstraction). We then design algorithms with clear steps for resolution. These elements together simplify understanding and tackling challenging issues, making solutions more efficient and manageable.
