Final answer:
The recipient of the message interprets its content, while a hash is used to ensure integrity and authenticity of data.
Step-by-step explanation:
The recipient of a message and a hash have different roles and functions. The recipient of the message is the intended receiver of the communication. They receive the message and interpret its content. On the other hand, a hash is a mathematical function that takes an input (data) and generates a fixed-size string of characters, which serves as a unique identifier for the input. In the context of computer science and security, the recipient of a message and a hash are used to ensure the integrity and authenticity of data. The recipient can verify the authenticity of a message by comparing the hash received with the recalculated hash of the message itself. If the hashes match, it means that the message has not been tampered with during transmission. For example, in email systems, when a recipient receives an email, the email message typically includes a hash value. By recalculating the hash of the received message, the recipient can compare it with the original hash to ensure that the message has not been altered in transit.
