What is the primary purpose of encryption?

To improve data processing speeds
To obscure data to prevent unauthorized access
To format data for network transmission
To create backups of sensitive information

The correct answer is: To obscure data to prevent unauthorized access

The primary purpose of encryption is to obscure data to prevent unauthorized access. By transforming readable data into a coded format, encryption ensures that only those with the appropriate decryption key can access the original information. This is crucial for protecting sensitive information from potential threats, such as data breaches or unauthorized interception during transmission. While encryption can have secondary effects on data processing speeds, it is not designed primarily to enhance performance. Formatting data for network transmission and creating backups are also important tasks, but they do not align with the core purpose of encryption, which is centered around safeguarding data integrity and confidentiality against unauthorized access.
