Which of the following is not a data processing operation?a. Data sortingb. Data compressionc. Data encryptiond. Data deletion

To answer the question about which operation is not typically considered a data processing operation, let’s analyze the options provided.

1. Data Sorting: This is a data processing operation where data is organized in a specific order, usually ascending or descending based on a certain criterion.

2. Data Compression: This operation reduces the size of data for storage efficiency, making it a valid data processing operation.

3. Data Encryption: While this involves altering data to secure it, it is not considered a traditional data processing operation aimed at organizing or managing data.

4. Data Deletion: This is the operation of removing data, which is indeed a form of data processing.

Conclusion

The operation that is not typically classified as a data processing operation is Data Encryption (c). While it's crucial for securing data, it fundamentally alters the data rather than organizing, managing, or processing it in a conventional sense.
