Which of the following methods is used to check the integrity of data?
- Hashes or checksums
Answers Explanation & Hints:
Hashes or checksums are used to check the integrity of data. Hashing is a process of generating a fixed-size string of characters, called a hash, from a piece of data using a mathematical function. The hash is unique to the input data, so any change in the data will result in a different hash value. By comparing the hash values of the original data and the received data, the integrity of the data can be checked. Checksums work similarly to hashes but are typically used to verify the integrity of files.
