What role does encryption play in data transmission?

Encryption plays a crucial role in data transmission by ensuring that the information being sent is kept private and secure. When data is encrypted, it is converted into a format that is unreadable to anyone who does not have the correct decryption key. This means that even if the data is intercepted by unauthorized individuals during transmission, they would be unable to understand or make use of it, as it appears as gibberish.

In addition to safeguarding against eavesdropping and unauthorized access, encryption also reinforces the integrity of the data by making it significantly more difficult for malicious actors to alter the content without detection. This level of security is essential for protecting sensitive information, such as personal data, financial records, and confidential communications, thereby fostering trust in digital communications and transactions. Security measures like encryption are foundational in compliance with regulations that protect personal data and privacy.

Other options do not accurately represent the primary function of encryption in data transmission. For instance, while data integrity is essential, preventing corruption typically relies on checksums or error-detection methods rather than encryption. Likewise, encryption does not enhance retrieval speed; the process of encrypting and decrypting data can add overhead. Finally, encryption does not negate the necessity for data backups since protecting against data loss involves additional
