Name a common method for verifying data integrity after conversion.

• A. Data encryption
• B. Data compression
• C. Checksums or hash functions
• D. User authentication

Answer: (C)

Checksums or hash functions are a widely used method for verifying data integrity after conversion because they provide a way to ensure that the data has not been altered during the conversion process. A checksum is a value derived from a set of data using a specific algorithm. When data is converted, a checksum is calculated before and after the conversion. By comparing these two checksums, one can verify whether the data remains unchanged. Using checksums or hash functions allows for a quick and reliable way to detect any discrepancies that may have occurred during conversion. If the checksums do not match, it indicates that the data may have been corrupted, altered, or otherwise compromised during the conversion process. This makes checksums and hash functions essential tools in maintaining data integrity, especially in contexts where accuracy is critical. In contrast, data encryption focuses on securing data from unauthorized access rather than verifying its integrity. Data compression reduces the size of data but does not provide any verification mechanism. User authentication is concerned with verifying the identity of individuals accessing data but does not relate to integrity checks of the data itself. Thus, checksums or hash functions stand out as the correct choice for verifying data integrity after conversion.
