Final answer:
Encryption is vital to secure communication between an end user and a data center, protecting data in transit from unauthorized access and potential threats.
Step-by-step explanation:
The question regards the encryption of communication for security purposes. In contexts such as cloud computing and data transfer, it is essential to encrypt the communication between the end user and the data center. This ensures that sensitive data is protected and prevents unauthorized access. When a user accesses data stored in a cloud service or a remote server, the data travels through a network, and without encryption, it could be vulnerable to interception or eavesdropping. Encryption technologies like SSL/TLS are used to encrypt the data in transit, making it unreadable to anyone other than the intended recipient with the proper decryption key.
