Checksum: meaning, definitions and examples
🔍
checksum
[ ˈtʃɛksˌʌm ]
data integrity
A checksum is a value used to verify the integrity of data. It is calculated from a set of data, allowing for error detection in data transmission or storage. If the checksum does not match the expected value, it indicates that the data may have been compromised or corrupted.

Etymology
The term 'checksum' is derived from the combination of 'check' and 'sum', referring to a value that is checked for accuracy in data. The concept of checksums has been prevalent in computing since the early days of data transmission and storage, where ensuring data accuracy was critical. Initially, checksums were simple sums of data bytes, but as technology evolved, more sophisticated algorithms were developed to enhance error detection capabilities. The use of checksums has expanded beyond basic error detection to applications in cryptography, data integrity verification, and network communications. These tools have become essential in modern computing, ensuring that data remains intact across various systems and platforms.
