What is one of the main advantages of using encryption?

One of the main advantages of using encryption is that it protects sensitive information from unauthorized access. Encryption works by converting data into a format that cannot be easily understood or accessed without the proper decryption key. This means that even if data is intercepted or accessed by malicious actors, it remains unintelligible without the correct decryption credentials. This is particularly important for securing personal information, financial data, and confidential communications, ensuring that only authorized users can access or decipher the information.

Other choices do not describe key benefits of encryption effectively. For instance, while enhancing internet speed or allowing for unlimited data storage might be desirable features in other contexts, they do not relate to the primary function of encryption. Likewise, creating backups of all data is not a direct application of encryption; rather, backups can also be encrypted as an additional layer of security but do not define the purpose of encryption itself.
