Protocol for Sending Encrypted Data over the Internet: SSL
Explanation:
To send encrypted data over the Internet, the Secure Sockets Layer (SSL) protocol is used. SSL provides a secure and encrypted connection between a client (such as a web browser) and a server (such as a website). Here is a detailed explanation of SSL and why it is the correct answer:
- SSL (Secure Sockets Layer):
- SSL is a protocol that ensures secure communication over the Internet.
- It uses encryption algorithms to encrypt data before transmission and decrypt it upon receipt.
- SSL establishes a secure connection by authenticating the server and, in some cases, the client.
- It provides confidentiality, integrity, and authenticity of the transmitted data.

- HTTPS (Hypertext Transfer Protocol Secure):
- HTTPS is an extension of the HTTP protocol that uses SSL/TLS encryption to secure the communication.
- It encrypts the data exchanged between a client and a server, preventing unauthorized access.
- HTTPS is commonly used for secure communication in activities like online banking, shopping, and accessing sensitive information.

- Other options:
- HTTP (Hypertext Transfer Protocol): HTTP is the standard protocol for transmitting data over the Internet. However, it does not provide encryption, making it unsuitable for sending sensitive data.
- SMPT (Simple Mail Transfer Protocol): SMTP is a protocol used for sending email. While it is involved in the transmission of data, it does not provide encryption by itself.
- FTP (File Transfer Protocol): FTP is a protocol used for transferring files between a client and a server. It does not provide encryption by default, but FTPS (FTP over SSL) is a variant that adds SSL/TLS encryption to FTP.

In conclusion, SSL (Secure Sockets Layer) is the correct answer as it is the protocol specifically designed for sending encrypted data over the Internet. It ensures the security and privacy of the transmitted information, making it a crucial component of secure communication on the web.
