Final answer:
Carla's time saving measure of sending unencrypted emails on occasion may not be appropriate. She should consider using encryption for all her communications to ensure privacy and security.
Step-by-step explanation:
Carla's time saving measure of sending unencrypted emails on occasion may not be appropriate. While she may consider these emails to be private, there is no guarantee that they will remain private. Once an email is sent, it can be intercepted or forwarded without her knowledge or consent.
To ensure the privacy and security of her emails, Carla should consider using encryption for all her communications. Encryption scrambles the content of the email, making it unreadable to anyone without the decryption key. This provides an extra layer of protection and reduces the risk of unauthorized access or distribution.
Hence, by using encryption, Carla can have peace of mind knowing that her messages are secure, even if they fall into the wrong hands.
